TL;DR: Although the survival rate has improved, paraplegia/paraparesis and kidney failure continue to be vexing problems that require further research.

TL;DR: Duplex scan determination of 70% to 99% stenosis as defined in the NASCET requires the adoption of duplex criteria modified from those in current use in most vascular laboratories, and an ICA PSV/CCA PSV ratio of 4.0 provided the best combination of sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy.

TL;DR: The incidence of aneurysm rupture in the city of Malmö, Sweden from 1971 to 1986 was not low compared with other Scandinavian studies, but was low in comparison with studies from the United Kingdom.

TL;DR: An in vitro tridimensional vascular model that exhibits some phenotypic characteristics of in vivo vascular cells could be useful in the study of events that lead to atherosclerotic plaque formations.

TL;DR: Early recanalization is important in preserving valve integrity for all but the posterior tibial segment, however, the small number of patients with reflux despite early lysis or without Reflux despite relatively late lysis suggests that other factors may also contribute to the development of valvular incompetence.

TL;DR: PTRA is recommended as first choice of therapy for atherosclerotic renal artery stenosis causing renovascular hypertension if combined with intensive follow-up and aggressive reintervention.

TL;DR: In the groups studied, an increased incidence of ulceration was associated with an increase in ambulatory venous pressure irrespective of whether the venous problem was the result of superficial or deep venous disease.

TL;DR: In this paper, the mesenteric duplex scanning was used to visualize the celiac (CA) and superior mesentic (SMA) arteries in 34 patients, and duplex-determined peak systolic velocities from CA and SMA were recorded without knowledge of the angiographic results.

TL;DR: Preliminary results show that straight and bifurcated endovascular grafts can be positioned accurately and securely in the abdominal aorta.

TL;DR: Although complete protection against persistent or recurrent infection has not been achieved and late deterioration may be expected, in situ allograft replacement seems to be a major advance in the management of infected infrarenal aortic prosthetic grafts.

TL;DR: It was concluded that a staged, multimodal approach to the Paget-Schroetter syndrome can effectively restore venous patency, reduce rethrombosis, and return normal function.

TL;DR: Magnetic resonance venography is an accurate noninvasive venographic technique for the detection of DVT and was found to be more accurate than contrast venography when compared with duplex scanning.

TL;DR: The thickness of the I-M complex of the common carotid arteries is a measure of the risk for the development of cardiovascular symptoms in symptom-free individuals.

TL;DR: This study confirms significant risk for asymptomatic patients with critical stenosis or echolucent plaque and demonstrates the importance of contralateral disease and the absence of orderly progression from minimal disease through high-grade stenosis to symptomatic cerebral ischemia.

TL;DR: All FAs do not thrombose spontaneously and at least one third require surgical repair, and patients receiving continuous anticoagulation should undergo aneurysm repair, while discharge of patients with FAs less than 6 cm3 is safe and many AVFs close spontaneously.

TL;DR: A 78-year-old man was seen with an expanding 5 cm false aneurysm of the right subclavian artery that was treated by an intraluminal graft-stent device introduced through the brachial artery via a 16 F sheath.

TL;DR: In just over half of patients with venous ulceration, the disease is confined to the superficial venous system, and this group of patients may benefit from surgical treatment.

TL;DR: This initial experience suggests that CTA may be a valuable alternative to conventional arteriography in the evaluation of the aorta and its branches in patients with abdominal aortic, renal, and visceral arterial disease.

TL;DR: This case report describes a new approach to repair a femoral arteriovenous fistula with a transluminally placed intraarterial graft-covered stent, inserting a balloon-expandable stented polytetrafluoroethylene graft after a bullet injured the left superficial femoral artery and vein of an 18-year-old man.

TL;DR: It is concluded that revision procedures were more optimally used during color-flow surveillance, whereas asymptomatic stenotic graft lesions are missed with clinical follow-up, which results in a higher percentage of graft failures.

TL;DR: Clinical assessment and duplex scanning were sufficient for the preoperative evaluation of 93% of the candidates for carotid endarterectomy and practical guidelines for the selective use of arteriography are developed.

TL;DR: The data strongly suggest that elastolysis is a primary event in AAA formation that occurs before over loss of adventitial structural integrity and the development of small aneurysms.

TL;DR: Findings demonstrate that accumulation of macrophages and T cells is an event associated with the development of liposclerotic skin changes that may lead to ulceration in venous disease.

TL;DR: Duplex surveillance of IRVGs is warranted by the 21% incidence of potentially remediable graft failure, mainly in the juxtaanastomotic position with reversed vein conduits.

TL;DR: The preliminary data support the presence of connective tissue abnormalities before valvular insufficiency and exclude enzymatic matrix degradation as an essential component in the formation of venous varicosities.

TL;DR: Revascularization of chronically ischemic bowel leads to significant multiple organ dysfunction, potentially as a result of intestinal ischemia and reperfusion injury.

TL;DR: Semiquantitative evaluation of theymphatic transport with lymphoscintigraphy reliably depicts abnormalities in the lymphatic circulation.
