What are the reasons for the occurrence of cerebral infarction in cardiac surgery? 


Best insight from top research papers

Cerebral infarction in cardiac surgery can occur due to various reasons. One of the main factors is intraoperative embolism, where a calcific embolus released during manipulation of the atheromatotic aorta can lead to cerebral infarction . Other risk factors include systemic inflammatory response syndrome, atrial fibrillation, temperature regulation, blood pressure control, and the use of postoperative blood products . Carotid artery stenosis, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation are also identified as risk factors for cerebral infarction after coronary artery bypass grafting (CABG) . Additionally, Coarctation of the aorta (CoA) patients undergoing reconstructive surgery may experience cerebral infarction as an adverse effect of the surgery . It is important to recognize these risk factors and take preventive measures during and after cardiac surgery to reduce the occurrence of cerebral infarction.

Is there a similar study on bp complications after pediatric cardiac surgery?5 answersThere is a study on blood pressure complications after pediatric cardiac surgery. Fishbein et al. conducted a retrospective chart review of children undergoing cardiac surgery with cardiopulmonary bypass (CPB) and assessed the association between intraoperative blood pressure variability (BPV) and the development of acute kidney injury (AKI). They found that greater BPV during cardiac surgery with CPB was associated with the development of postoperative AKI in infants, suggesting that BPV is a potentially modifiable risk factor for AKI in this high-risk population.
Does cardiac surgery have more sequelae and complications compared to other surgeries?5 answersCardiac surgery can have a wide array of complications and sequelae, affecting various body systems such as neurological, pulmonary, cardiac, renal, and mesenteric. The Clavien-Dindo Complications Classification (CDCC) and the Comprehensive Complication Index (CCI) have been successfully implemented to quantify postoperative morbidities in cardiac surgery. Elderly patients and those with multiple concomitant disorders undergoing cardiac surgery are at a higher risk of postoperative cardiac complications, including supraventricular tachycardia, atrial fibrillation, and postoperative bradycardia. Studies have focused on identifying predictors of perioperative complications in cardiac surgery to prevent untoward outcomes and optimize patient care. While morbidity and mortality rates have improved in cardiac surgery, errors in the operating room remain a major cause of preventable adverse events and avoidable death. Therefore, it is important to learn from surgical missteps and avoid repeating mistakes in the future.
What are the causes of MCA infarct?5 answersThe causes of MCA infarct include hypovolemia due to massive hemorrhage, intracranial artery disease such as hypertension and diabetes mellitus, and arterial thrombosis associated with COVID-19 infection.
What are the most common complications after stroke surgery?5 answersThe most common complications after stroke surgery include cardiac complications, pneumonias, venous thromboembolism, fever, pain, dysphagia, incontinence, and depression. Other complications may include deep venous thrombosis, pulmonary embolism, falls, systemic infections, cerebral edema, elevated intracranial pressure, hemorrhagic transformation, and seizures. Medical complications such as fever, infections, hyperglycemia, cardiac disorders, pressure sores, and deep venous thrombosis are associated with a poor prognosis and should be treated as early as possible. Timely identification and management of issues with other systems following stroke surgery are important for improving functional recovery and shortening hospital stays.
What are the most common reasons for stroke patients to be transferred to the surgical intensive care unit?5 answersThe most common reasons for stroke patients to be transferred to the surgical intensive care unit (ICU) include the presence of stroke-associated pneumonia (SAP) and the need for endovascular thrombectomy (EVT). SAP is a complication of stroke that can lead to increased morbidity and mortality. It is more commonly seen in patients with a history of diabetes mellitus (DM), hypertension (HTN), and a duration of stroke between 6 to 12 hours. However, these factors were not found to be statistically significant. EVT is a procedure used to remove large vessel occlusions in emergent large vessel occlusion (ELVO) strokes. Transfer to the surgical ICU may be necessary for patients undergoing EVT to receive specialized care.
What are the risks associated with CABG surgery?2 answersCoronary artery bypass grafting (CABG) surgery carries significant risks and complications. The most serious adverse events include death, stroke, bleeding requiring further surgery, peri-operative myocardial infarction, cardiac arrhythmias, and deep sternal wound infection. Other complications that can occur include sternal wound infections, pneumonia, thromboembolic phenomena, graft failure, atrial fibrillation, pulmonary hypertension, pericardial effusion, strokes, renal injury, gastrointestinal insults, and hemodynamic instability. Risk factors for sternal wound infections after CABG surgery include diabetes mellitus and obesity. CABG-associated stroke is a major concern, with risk factors including surgery with cardiopulmonary bypass and hyperthermic circulatory arrest, older age, and preoperative atrial fibrillation. Overall, CABG surgery is a complex and high-risk procedure that requires careful management and monitoring to minimize complications and improve patient outcomes.
