Background Portal vein aneurysms are rare dilations in the portal venous system, for which the etiology and pathophysiological consequences are poorly understood. Method We reviewed the existing literature as well as present a unique anecdotal case of a patient presenting with a very large portal vein aneurysm that was successfully managed conserv...
Article
Objective: Multiple vascular inflow reconstruction options exist for claudication, including aortofemoral bypass (AFB) and alternative inflow procedures (AIPs) such as femoral reconstruction with iliac stents, and femoral-femoral, iliofemoral, and axillofemoral bypass. Contemporary multi-institution comparison of these techniques is lacking. Meth...
Article
Objective: National data evaluating outcomes for occlusive abdominal aortic reconstructions are well described. The relative effect of operative indication as well as the presence of concomitant abdominal aortic aneurysm (AAA) on in-hospital mortality is not well defined. Methods: The Nationwide Inpatient Sample was queried to identify patients...
Article
Background We compared the early postoperative morbidity and mortality rates of contemporary aortofemoral bypass (AFB) and other inflow procedures for claudication. Methods We identified 1974 claudicants who underwent elective AFB (n = 566) or non-AFB (nonaortofemoral bypass [NAFB]; n = 1408) inflow reconstruction using the ACS-NSQIP database (200...
Article
Infected aortic aneurysms (IAAs) are rare but can have devastating outcomes, particularly if diagnosis and treatment are delayed. The incidence of IAA is between 0.65% and 2% of all aortic aneurysms. The disease has a poor prognosis because these aneurysms have an increased tendency to grow rapidly and to rupture, and patients often have severe com...
Article
An isolated external iliac artery chronic total occlusion is currently treated either with subintimal percutaneous transluminal angioplasty and stent or with a bypass. This article describes a new application of an old technique, endarterectomy and patch angioplasty, performed on the external iliac artery through a single flank incision. This novel...

Une occlusion totale chronique isolée de l'artère iliaque externe est actuellement traitée par angioplastie transluminale percutanée sous-intimale avec stent ou par pontage. Cet article décrit une nouvelle application d'une vieille technique, l’endartériectomie avec angioplastie par patch, faite sur l'artère iliaque externe par une incision unique...

... 2,3 This result is also consistent with results from 2 other recent analyses from national databases, as well as our own institutional review. 14,21,22 It is difficult to compare the rate of major morbidity after ABF bypass across studies given the varying definitions in each individual study; however, rates of individual complications seem to be consistent with large contemporary cohorts. 4,21,22 Factors related to operative complexity, such as simultaneous lower extremity intervention, increasing operative time, and increasing operative blood loss, as predictors of perioperative major adverse events are consistent with results from our institutional review. ...
... The 30-day mortality and complication rate after open repair of an abdominal aortic aneurysm (AAA) by implanting a tube or bifurcated aorto-iliac graft have been well documented in many large patient series [1][2][3][4]. Similarly, the 30-day mortality and complication rate after aortofemoral or aorto-bifemoral bypass used to treat aorto-iliac occlusive disease (AIOD) is well established [5][6][7]. The prevalence of severe AIOD in AAA patients or the presence of an AAA in patients with severe AIOD is reported to be around 20% [8]. ...
... Pathological examination suggests that MRAAs develop from septic emboli that penetrate the vasa vasorum, seeding adventitial inflammation and dilation of the weakened arterial wall [9]. Growth rates of mycotic aneurysms have been reported in the thoracic and abdominal aorta [12][13][14], but this is the first case report to document the growth rate of a MRAA. ...
... While endovascular therapies are now employed for many obstructive CVDs due to their minimally invasive nature and rapid recovery times, open surgical repair using bypass grafts remains the gold standard for many patients due to better long-term outcomes and wider applicability to complex lesions [2][3][4]. For lower extremity peripheral artery occlusive disease, biological or synthetic grafts in the form of a patch [5][6][7] or tubular bypass [8][9][10][11] are frequently used to restore and maintain blood flow. Autologous saphenous vein grafts demonstrate superior patency rates [8][9][10] but, in many cases, this vein is unavailable due to comorbidities, size mismatch, or previous revascularization procedures [11]. ...
