Duplex ultrasound was used to study the diameters, flow patterns, and peak blood flow velocities of the common femoral vein (CFV) in 12 normal subjects (mean age 35 years). Each subject was supine and non-weight-bearing on a tilt table and rotated in 10-degree increments from -10 degrees (head down) to +30 degrees (head up). Cross-sectional B-mode ...

Aortobifemoral bypass (ABF) is the preferred operation for patients with bilateral aortoiliac occlusive disease, but for those with unilateral occlusion without significant stenosis of the contralateral iliac artery, alternative reconstructions, such as femorofemoral (FF) or iliofemoral (IF) bypass have been advocated. We compared the surgical outc...

Survival in patients with diminished left ventricular ejection fraction (EF) is reduced after major vascular surgery. The objective of this study was to determine perioperative (30-day) and subsequent outcome after major vascular surgery in those with severe cardiac dysfunction, defined by EF being 35% or less (normal EF greater than 50%). From Aug...

Two hundred forty-nine well-characterized difficult distal bypasses, entered into a multicenter dextran 40 trial, were reevaluated after 3 years. Seventy in situ (IS) vein grafts, 49 reversed saphenous (RS) vein grafts, 60 polytetrafluoroethylene (PTFE) grafts, and 70 umbilical vein (UV) grafts were used. Primary and secondary patency rates at 3 ye...

The treatment of 41 patients with chronic mesenteric insufficiency is reviewed: 20 men and 21 women with a mean age of 59 years were treated and observed for an average of 42 months. Thirty-one patients had symptoms of intestinal angina whereas 10 patients underwent prophylactic revascularization during other aortic operations. All but one patient ...

The existence of inhibitors of plasminogen activator has been shown to play an important role in regulation of fibrinolysis and postoperative thrombosis. Platelets and endothelium are sources of plasminogen activator inhibitor (PAI). This study determines the contribution of platelet-released PAI to perioperative fibrinolytic shutdown. PAI levels w...

Although complications of balloon catheter embolectomy are infrequent, the injury potential of these catheters is well recognized. This article describes a case of multiple tibial artery pseudoaneurysms that appeared 4 years after embolectomy in a 42-year-old man with otherwise normal arteries. The patient was treated by internal aneurysmorrhaphy w...

Between 1982 and 1987, 32 patients with severe aortorenal atherosclerosis had simultaneous aortic and bilateral renal revascularization. All patients were hypertensive. Eighteen patients (56%) had renal insufficiency with a mean serum creatinine (SC) of 2.8 mg/dl. Nine patients had an aortic aneurysm; the remaining 23 patients had aortoiliac occlus...

Hypertension as a result of proximal renal artery stenosis has been described in patients with neurofibromatosis, but a review of the English language literature showed no familial incidence of renovascular lesions in association with neurofibromatosis. We report a case of neurofibromatosis in a 24-year-old white woman with renovascular hypertensio...

The Kensey dynamic angioplasty instrument is an atherectomy device approved by the Food and Drug Administration that uses a rotating cam tip housed within a flexible polyurethane catheter to recanalize obstructed and stenotic arteries. Twenty patients with significant femoral arteriosclerotic occlusive disease underwent attempted transluminal endar...
