Liver Cirrhosis Patient with Complications of Hepatic Hydrothorax. Case Report

Abstract: Introduction: Hepatic hydrothorax is that occurs in individuals with decompensated cirrhosis of the liver. Approximately 5 % of cases of pleural effusion occur in patients with cirrhosis and ascites. Although quite rare, it is associated with higher morbidity and lower survival rates. The mechanism is not fully understood, but the most widely accepted pathogenesis involves the presence of portal hypertension, diaphragmatic defects, and negative intrathoracic pressure. In this case, the pleural effusion occurs because of the direct displacement of peritoneal fluid through the small openings in the diaphragm into the pleural space. We aimed to study its clinical features and natural history.

Fetal Hydrothorax Treated with Pleuro-Amniotic Shunting: Fetal and Maternal Complications and Long-Term Outcomes

Abstract: Introduction: We aimed to identify maternal and fetal complications and investigate postnatal and long-term outcomes of fetal hydrothorax (FHT) treated with pleuro-amniotic shunting (shunt). Methods: Single-center retrospective observational cohort of shunt cases performed from 2000 to 2021. Risk factors for maternal complications, fetal demise, neonatal death (NND), and postnatal outcomes were identified. Results: Out of 88 cases, 70 (79.5%) were complicated by hydrops, with an average gestational age (GA) at diagnosis of 27 weeks (range 16–34). In 16 cases, definitive etiology of FHT was identified; five cases of Noonan syndrome and three cases of monogenic disorders diagnosed by whole-exome sequencing (EPHB4, VEGFR3, RASA1). Shunt was performed at an average GA of 28 weeks (20–34), with a dislodgement in 10 cases (11.4%). Maternal: Complications occurred in three cases; survival rate was 76.1% (67/88). Follow-up data were available for 57/67 (85.1%) children. Incidence of severe neurodevelopmental impairment and pneumopathy (broncho dysplasia, persistent pulmonary hypertension of newborn, and asthma) was 5.3% and 8.8%, respectively. Post-treatment persistence of hydrops, FHT associated with genetic syndromes, and GA at birth were risk factors for fetal demise, NND, and postnatal complications. Conclusion: In truly isolated FHT, whenever indicated, pleuro-amniotic shunting is a safe procedure associated with good survival rate and long-term outcome.

Pseudo-Meigs’ syndrome secondary to breast cancer with ovarian metastasis: a case report and literature review

Abstract: Ovarian metastasis of breast cancer with pseudo-Meigs’ syndrome (PMS) is extremely rare. Only four cases of PMS secondary to breast cancer with ovarian metastasis have been reported to date. In this report, we present the fifth case of PMS caused by ovarian metastasis of breast cancer. On the 2nd of July 2019, a 53-year-old woman presented to our hospital with complaints of abdominal distension, irregular vaginal bleeding, and chest distress. Color Doppler ultrasound examination revealed a mass approximately 109×89 mm in size in the right adnexal area, accompanied by multiple uterine fibroids and a large amount of pelvic and peritoneal effusions. The patient had no common symptoms and showed no signs of breast cancer. The main manifestations were a right ovarian mass, massive hydrothorax, and ascites. Lab workup and imaging revealed raised CA125 (cancer antigen 125) levels and multiple bone metastases. At first the patient was misdiagnosed with ovarian carcinoma. After the rapid disappearance of oophorectomy hydrothorax and ascites, and decreased CA125 levels, from 1,831.8u/ml to normal range. According to the pathology report, breast cancer was finally diagnosed. The patient underwent endocrine therapy (Fulvestrant) and azole treatment after oophorectomy. At the 40-month follow-up, the patient was still alive and doing well.

Tapped Twice: A Case of a Rapidly Re-accumulating Hepatic Hydrothorax in a Patient with Spontaneous Bacterial Empyema

Abstract: Hepatic hydrothorax (HH) is a complication of decompensated liver cirrhosis that only occurs in about 5–6% of cirrhosis patients, defined as a pleural fluid in the setting of known liver disease, with the absence of any other cardiopulmonary etiology. Infected HH is a rare complication, designated as spontaneous bacterial empyema (SBEM), found in only 13–16% of patients with HH. This case follows a patient with SBEM who developed a recurrent pleural effusion minutes after thoracentesis. Our patient is a 56-year-old female with a history of alcoholic cirrhosis with pleuritic pain found to have right-sided pleural effusion with decompensation. She had no ascites. She was initiated on antibiotics due to leukocytosis and underwent thoracentesis, revealing a sterile but exudative pleural effusion with high neutrophil count, confirming the diagnosis of SBEM. Despite initial symptom relief, her respiratory symptoms recurred within mere minutes of thoracentesis. Imaging showed reaccumulated right-sided effusion, and repeat thoracentesis showed a transudative effusion, suggesting HH. While she was in our care, we pursued expert consultation with gastroenterology and thoracic surgery; based on our shared clinical decision making, we agreed that definitive intervention with either indwelling catheter or intrapleural surgical options would cause more harm than good to our patient given her decompensated alcoholic cirrhosis. The patient was discharged with instructions for serial thoracentesis and close follow-up with gastroenterology to discuss next steps regarding her advanced and uncontrolled cirrhosis. We refer to this case to discuss HH and its rare complication of SBEM, as well as the management options for patients with these conditions.

A practical approach to pseudoexudative pleural effusions.

Abstract: Light's criteria falsely label a significant number of effusions as exudates. Such exudative effusions with transudative etiologies are referred to as "pseduoexudates". In this review, we discuss a practical approach to correctly classify an effusion that may be a pseudoexudate. A PubMed search yielded 1996 manuscripts between 1990 and 2022. Abstracts were screened and 29 relevant studies were included in this review article. Common etiologies for pseudoexudates include diuretic therapy, traumatic pleural taps, and coronary artery bypass grafting. Here, we explore alternative diagnostic criteria. Concordant exudates (CE), defined as effusions where proteins in pleural fluid/serum (PF/SPr) > 0.5 and pleural fluid LDH level of >160 IU/L (>2/3 upper limit of normal) confer higher predictive value to the Light's criteria. Serum-pleural effusion albumin gradient (SPAG) > 1.2 g/dL and serum-pleural effusion protein gradient (SPPG) > 3.1 g/dL together yielded a sensitivity of 100% in heart failure and a sensitivity of 99% in hepatic hydrothorax whe n identifying pseudoexudates (Bielsa et al., 2012) [5]. Pleural fluid N-Terminal Pro Brain Natriuretic Peptide (NTPBNP) offered a specificity and sensitivity of 99% in identifying pseudoexudates when using a cut-off of >1714 pg/mL (Han et al., 2008) [24]. However, its utility remains questionable. Additionally, we also looked at pleural fluid cholesterol and imaging modalities such as ultrasound and CT scan to measure pleural thickness and nodularity. Finally, the diagnostic algorithm we suggest involves using SPAG >1.2 g/dL and SPPG >3.1 g/dL in effusions classified as exudates when there is a strong clinical suspicion for pseudoexudates.

Portal Hypertension Refractory Ascites Caused by Secondary Hemochromatosis

Abstract: We report a patient with refractory ascites because of portal hypertension caused by hemochromatosis secondary to osteopetrosis. To our knowledge, this is the first well-documented case of this association. A 46-year-old male patient who was repeatedly infused with red blood cells for anemia secondary to osteopetrosis suffered from refractory ascites. The serum-ascites albumin gradient was 29.9 g/L. Abdominal computed tomography (CT) showed a large amount of ascites, hepatomegaly, and splenomegaly. Bone marrow biopsy showed a small bone marrow cavity with no hematopoietic tissue. A peripheral blood smear showed tear drop red blood cells and metarubricytes. Serum ferritin was 8,855.0 ng/mL. Therefore, we considered that the ascites resulted from portal hypertension caused by hemochromatosis secondary to osteopetrosis. We simultaneously performed the transjungular intrahepatic portal-systemic shunt (TIPS) and obtained a transjungular liver biopsy. The portal pressure gradient before TIPS was 28 mmHg, and iron staining was strongly positive on liver biopsy, which confirmed our diagnosis. After TIPS, both abdominal distention and ascites gradually resolved, and no recurrence as observed after the 12-month postoperative follow-up was observed. This case indicated that regular monitoring of iron load is important for patients with osteopetrosis. TIPS is safe and effective for portal hypertension complications due to osteopetrosis.

Tension hydrothorax in a patient with a history of pulmonary tuberculosis

Abstract: A tension hydrothorax is a massive pleural effusion that leads to hemodynamic instability. Here we present a case of tension hydrothorax secondary to poorly differentiated carcinoma. A 74-year-old male smoker presented after a one-week history of dyspnea and unintentional weight loss. Physical exam demonstrated tachycardia, tachypnea, and decreased breath sounds diffusely over the right lung. Imaging revealed a massive pleural effusion causing mass effect on the mediastinum with tension physiology. Chest tube placement revealed an exudative effusion with negative cultures and cytology. Pleural biopsy revealed atypical epithelioid cells consistent with poorly differentiated carcinoma.

Intravascular Ultrasound for Transjugular Intrahepatic Portosystemic Shunt Creation: “TIPS” and Tricks

Abstract: Cirrhosis affects 4.5 million people in the United States. 1 Sequela of cirrhosis and portal hypertension include varices, which occur in upto 60 to80% ofcirrhotic patients and pose a bleedingriskof25to35% 2 ;refractoryascites,whichoccurs in 5 to 10% of patients 3 ; recurrent hepatic hydrothorax, which occurs in 5 to 10% of cirrhotic patients 4 ; and hepatic enceph-alopathy, which occurs in up to 45% of patients with cirrhosis. 5 Transjugular intrahepatic portosystemic shunt (TIPS) creation results in portal venous decompression and reduces mortality and morbidity associated with these portal hyper-tensive sequelae. There is a clear survival bene fi t with TIPS creation in patients at risk of variceal hemorrhage, including those who fail endoscopic banding, who are at high risk of pharmacologic or endoscopic treatment failure, 6 and who undergo early TIPS creation for secondary prophylaxis against bleeding. 7,8 For those with refractory ascites and hepatic hydrothorax, resolution of fl uid accumulation can be expected in 85% 9 and 82%, respectively. 10

Open Thoracic Drainage Followed by Proximal Splenic Artery Embolization for Massive Hydrothorax Before Living Donor Liver Transplantation.

Abstract: Hepatic hydrothorax is associated with postoperative infectious complications and mortality in patients undergoing living-donor liver transplantation (LDLT). Thus, preoperative management of massive hepatic hydrothorax is essential for improving the outcomes of LDLT. This study aimed to demonstrate our successful cases and strategy for treating massive hepatic hydrothorax. Our strategy for hepatic hydrothorax includes (a) mini-thoracotomy under general anesthesia for the drainage of hydrothorax, (b) preoperative hepatic inflow modulation by proximal splenic arterial embolization, and (c) nutritional and physical intervention to improve the general condition. Two patients with massive hepatic hydrothorax were treated with our strategy. Both patients had end-stage liver disease secondary to primary biliary cholangitis. Their performance status deteriorated due to massive hydrothorax. After the intervention, their performance status significantly improved. After that, LDLTs with right lobe grafts were performed. The duration of the operation was 440 and 343 minutes, with an intraoperative blood loss of 1,700 and 1,600 g, respectively. Their postoperative courses were uneventful, and they were discharged on postoperative days 16 and 14. Our pre-LDLT multimodal management strategy for massive hepatic hydrothorax, including preoperative open thoracic drainage, pre-LDLT portal inflow modulation, and nutritional intervention, improved the preoperative condition of patients undergoing LDLT, resulting in successful outcomes.

Recurrent pleural effusion from ovarian hemangioma: A rare pseudo‐Meigs syndrome presentation

Abstract: Pleural effusion is a common condition related to various diseases such as heart failure, malignancies, and pneumonia. Ovarian hemangioma is a rare type of female genital tumour and can rarely cause pleural effusion. In this case, we present a 48‐year‐old female with repeated episodes of recurrent right‐sided pleural effusion over 1 year with no clear aetiology. Abdominal computed tomography revealed a large left ovarian mass. After surgical removal of the mass, the repeated pleural effusion episodes ceased, and histopathology analysis reported a rare ovarian hemangioma. Pseudo Meigs' syndrome is a triad of an ovarian tumour, ascites, and hydrothorax that rarely presents with ovarian hemangioma; both effusions are eradicated after removing the tumour.

Risk factors for hepatic hydrothorax in patients with cirrhosis: a clinical retrospective study

Abstract: Aims and background Hepatic hydrothorax, which presents as an unexplained pleural effusion, is one of the important complications in patients with end-stage cirrhosis. It has a significant correlation with prognosis and mortality. The aim of this clinical study was to detect the risk factors for hepatic hydrothorax in patients with cirrhosis and to better understand potentially life-threatening complications. Methods Retrospectively, 978 cirrhotic patients who were hospitalized at the Shandong Public Health Clinical Center from 2013 to 2021 were involved in this study. They were divided into the observation group and the control group based on the presence of hepatic hydrothorax. The epidemiological, clinical, laboratory, and radiological characteristics of the patients were collected and analyzed. ROC curves were used to evaluate the forecasting ability of the candidate model. Furthermore, 487 cases in the experimental group were divided into left, right, and bilateral groups, and the data were analyzed. Results The patients in the observation group had a higher proportion of upper gastrointestinal bleeding (UGIB), a history of spleen surgery, and a higher model for end-stage liver disease (MELD) scores compared with the control group. The width of the portal vein (PVW) (P = 0.022), prothrombin activity (PTA) (P = 0.012), D-dimer (P = 0.010), immunoglobulin G (IgG) (P = 0.007), high-density lipoprotein cholesterol (HDL) (P = 0.022), and the MELD score were significantly associated with the occurrence of the hepatic hydrothorax. The AUC of the candidate model was 0.805 (P < 0.001, 95% CI = 0.758–0.851). Portal vein thrombosis was more common in bilateral pleural effusion compared with the left and right sides (P = 0.018). Conclusion The occurrence of hepatic hydrothorax has a close relationship with lower HDL, PTA, and higher PVW, D-dimer, IgG, and MELD scores. Portal vein thrombosis is more common in cirrhotic patients with bilateral pleural effusion compared to those with unilateral pleural effusion.

Hydrothorax with Atypical Features as a Complication of Peritoneal Dialysis: A Case Report and Literature Review

Abstract: Hydrothorax is an uncommon but established complication of peritoneal dialysis, usually arising from pleuroperitoneal leak. There is currently no consensus on definitive testing or management. Thoracentesis, sclerosing agents, and either temporary or permanent discontinuation of peritoneal dialysis in favor of hemodialysis are often considered. We report an unusual case of right-sided PD-associated hydrothorax in a 54-year-old female with a history of hypertension and anemia, who presented without chest pain or dyspnea but rather with fatigue and syncope. We review the current literature on this etiology regarding underlying causes, as well as best practices for diagnosis and treatment.

Hydrothorax and Peritoneal Dialysis

Abstract: Peritoneal dialysis (PD) hydrothorax is a well-known, albeit uncommon, complication of PD. It happens as a result of the passage of PD fluid through a diaphragmatic defect. Two factors are involved in the pathogenesis of PD hydrothorax: presence of peritoneo-pleural communication such as congenital defects and increased intraperitoneal pressure, which drives the fluid from the peritoneal to the pleural cavity. Patients with PD hydrothorax usually present with shortness of breath and have pleural effusion on chest radiograph, usually on the right side. Analysis of pleural fluid sample should reveal sterile transudate. A very high glucose concentration in the pleural fluid analysis has a high positive predictive value. Different imaging modalities such as peritoneal scintigraphy, computed tomography peritoneography, and magnetic resonance imaging have been used for the diagnosis of PD hydrothorax, but all lack high sensitivities. Awareness of PD hydrothorax is essential. Once suspected, PD should be stopped until thoracocentesis (which can be done for diagnosis and relief of symptoms) and/or imaging studies are done. Therapeutic options include (1) conservative management where PD is stopped, and patients are transitioned to hemodialysis temporarily and subsequently rechallenged with PD; (2) pleurodesis, whether blind or through thoracoscopy; and (3) surgical repair through video-assisted thoracoscopic surgery or through thoracotomy.

Ovarian Carcinoma Presenting as Meigs’ Section Syndrome- A Rare Case Report

Abstract: Presence of fluid and air within pleural space is known as hydropneumothorax. A large proportion of patients present with shortness of breath, dry cough and pricking type of pleuritic chest pain as a result of pleural involvement. However, fever and constitutional symptoms like loss of appetite and loss of weight is most likely associated with tuberculosis. Meigs’ syndrome is a triad of ascites, hydrothorax and benign ovarian tumours (ovarian fibromas and fibrothecomas). Pseudo-Meigs’ syndrome shows accumulation of ascites, pleural effusion and associated with a pelvic or abdominal tumours. Here, is a case report of a 62-year-old postmenopausal female, who presented with right pleuritic chest pain and breathlessness, since one week. Chest radiograph showed right-sided hydropneumothorax which required an intercostal drainage tube insertion. Upon further evaluation, the primary unknown cancer was found to be of ovarian origin.

Case report of serial pleural effusion managed with good fetal outcome

Abstract: Fetal pleural effusion is a rare congenital anomaly that occurs when some amount of fluid surrounds the fetal lung without concomitant hydrops. It may remain the same or progress more. We present here a case of a 32-year-old lady with primary infertility who conceived naturally. She presented to us for her routine term pregnancy evaluation. At 17 weeks her targeted imaging for fetal anomalies (TIFFA) scan revealed left side severe fetal hydrothorax. Again at 29 weeks left pleural effusion was noted. A C-section was performed at 38th week of pregnancy and a male child weighing 2.995 grams was born, with no need for ventilator support.

Hepatic hydrothorax is not associated with increased complications or poor survival after liver transplantation

Abstract: ABSTRACT Background Hepatic hydrothorax (HH) is associated with a poor prognosis. Liver transplant (LT) is the best treatment modality. We aim to assess post-LT morbidity and mortality in patients with cirrhosis and HH. Research design and methods Adult patients with cirrhosis, who underwent LT at our institution from 2015 to 2020, were retrospectively reviewed. Baseline data was obtained at the time of LT. Patients were followed from baseline until the last follow-up or death. Censoring occurred at the time of the last follow-up or death, whichever occurred earlier. Cumulative incidence of outcomes was determined by the Kaplan–Meier method. Short-term post-operative complications were compared between both groups as well. Results 428 patients had a LT, of which 72 (16.8%) had HH. Most of the baseline characteristics were similar between patients with and without HH; however, patients in the HH group had a higher proportion of pre-operative history of ascites and hepatic encephalopathy. Pre-operative HH was not significantly associated with post-LT mortality (Hazard ratio 1.12, 95% confidence interval 0.54-2.32; P-value 0.76). Patients had similar short-term post-operative complications between both groups. Conclusions LT is an excellent therapeutic option for patients with cirrhosis and HH, with excellent long-term survival without increased morbidity.

A deep learning system to predict origins for cancers of unknown primary using cytological images from hydrothorax and ascites.

Abstract: e13628 Background: Cancer of unknown primary (CUP) origin is still a mystery in the field of tumor diagnosis, which is difficult to be diagnosed by conventional imaging methods. The aim of this study is to develop a deep learning based method to assist pathologists in determining the origin of malignant hydrothorax and ascites using cytological images. Methods: By curating cytology images of hydrothorax and ascites from 42682 cases at three hospitals, we developed a deep-learning-based method -Tumor Origin diffeRentiation for Cytological Histology (TORCH)- for diagnosis of malignancy and prediction of tumor origin. We examined its performance on three individual test sets (n=12799). We compared TORCH with a panel of four pathologists on 496 cases that were randomly selected from test sets. Area under the receiver operating characteristic curve (AUROC) was used as the primary classification metric. Metrics including accuracy, sensitivity, specificity, precision and negative predictive value were used to measure the efficacy of TORCH versus pathologists. A score system was used to evaluate and compare the performance between our AI model and pathologist experts. Attention heatmap was used to interpret model prediction results. Results: TORCH model reached an overall micro-average one versus rest auroc of 0.957(95% CI: 0.955-0.959). On the three test sets, TORCH achieved an AUROC of 0.964 (95% CI 0.957-0.972), 0.947 (0.940-0.953), and 0.988 (0.985-0.993) in the diagnosis of cancer and 0.947 (0.942-0.952), 0.957 (0.953-0.960) and 0.972 (0.968-0.976) in localization of tumor origin, respectively. For primary tumor origin prediction, TORCH achieved an overall top-1 accuracy of 79.2% and top-3 accuracy of 98.5%. On three test sets, the top-1 accuracy was 75.7%, 79.4%, and 85.0% respectively. Compared with pathologists, TORCH demonstrated a better prediction efficacy (1.665 ± 0.677 vs. 1.265 ± 0.555; P <0.001). The mean diagnostic score of junior pathologists assisted with TORCH was also remarkably higher than the previous one (1.326 ± 0.728 vs. 1.101 ± 0.824; P <0.001). The comprehensive accuracy of attention heatmaps capturing main area of isolated tumor cells was 87.3% (95% CI: 81.9-92.8%). Conclusions: TORCH model was able to provide relatively accurate diagnosis of malignancy and prediction of tumor cell origin in hydrothorax and ascites. It can be used as an effective ancillary method to aid clinicians in allocating personalized therapy and improving patients’ prognosis.

Meigs syndrome: About an uncommon case report

Abstract: Background: Ovarian fibroma is a very unusual epithelial tumor representing less than 1% of all ovarian tumors. It can be asymptomatic and discovered during surgery or be associated with a pleural effusion preferentially located on the right side and a more or less abundant free ascites in the framework of the so-called Meigs syndrome. The challenge of management then lies in distinguishing benign from malignant since clinically, radiologically, and biologically everything points towards malignant which requires radical surgical treatment. We report here the case of a 69-year-old postmenopausal patient with a clinical form of Meigs' syndrome that strongly suggested ovarian cancer. Case presentation: We hereby report here the case of a 69-year-old patient, menopausal, gravida 4 para 3 with 3 live children delivered vaginally and one miscarriage. She presented with ascites, hydrothorax, and a solid tumor of the ovary. Serum CA 125 and HE 4 levels were very high. ROMA score was highly suggestive of malignancy. A hysterectomy with adnexectomy was performed. It was only the histological evidence of ovarian fibroma and the rapid resolution of its effusions that confirmed Meigs syndrome. Conclusion: Meigs syndrome is an anatomical-clinical entity that associates a benign tumor of the ovary, ascites, and hydrothorax. Highly elevated CA 125 and HE-4 tumor markers often point clinicians toward a malignant tumor and compel radical surgical treatment. This case report reminds us once again that only histology confirms the diagnosis of cancer.

Clinical features of severe ovarian hyperstimulation syndrome with hydrothorax

Abstract: Abstract Research question: Does the presence of hydrothorax suggest that severe ovarian hyperstimulation syndrome (OHSS) is associated with more severe conditions and worse pregnancy outcomes? Design: The clinical data for 868 hospital patients with severe OHSS following IVF-ET at Peking University Third Hospital between January 1, 2016, and July 21, 2021, were retrospectively analysed. The patients were divided into two groups: the ascites alone group (n = 417) and the ascites combined with hydrothorax group (n = 451) to investigate the clinical features and pregnancy outcomes of patients with severe ovarian hyperstimulation syndrome (OHSS) combined with hydrothorax plus ascites. Results The clinical data for 868 hospital patients with severe OHSS following IVF-ET were included. The patients were divided into two groups: the ascites alone group (n = 417) and the ascites combined with hydrothorax group (n = 451). 51.96% of patients with severe OHSS had hydrothorax plus ascites, mainly bilateral and moderate hydrothorax. Most cases with hydrothorax could be monitored and observed, and only 2.66% of the cases required thoracentesis and pleural drainage. Clinically, time to visit due to worsening symptoms was longer; hospital stay was shorter; and OHSS-related laboratory tests such as white blood cells (WBC), haematocrit (HCT), and ovarian diameter were less severe in the ascites combined with hydrothorax group than in the ascites alone group. For live-birth outcomes of IVF-ET, the presence and the volume of hydrothorax were not independent risk factors, while late onset of OHSS (odds ratio [OR]: 0.857 95% confidence interval [CI]: 0.795, 0.925) and a history of foetal reduction (OR: 13.796 95% CI: 1.808, 105.288) were independent protective factors for live birth. Conclusion Patients with severe OHSS combined with hydrothorax plus ascites have less severe clinical manifestations and laboratory tests than those with ascites alone. The presence and the volume of hydrothorax are unrelated to live-birth outcomes following in vitro fertilization and embryo transfer (IVF-ET).
