Activation of the innate immune system, even by relatively innocuous stimuli, stimulates the release of cytokines (e.g. TNF) that can injure or kill the host. To maintain homeostasis, mammals have evolved a counter-regulatory response that suppresses the development of excessively robust inflammation. Fetuin, a 66-kD negative acute phase glycoprotein, was(More)
Compartment syndrome is a rare and dangerous complication of coronary artery bypass. All reported cases involved the vein donor limb. Once recognized, immediate fasciotomy is necessary to prevent irreversible ischemia and limb loss. Diagnosis requires a high index of suspicion and close observation of the patient, particularly those remaining intubated(More)
OBJECTIVE Hypogastric artery (HA) occlusion during aortic aneurysm repair has been associated with considerable morbidity. We analyzed the consequences of interrupting one or both HAs in the standard surgical or endovascular treatment of aortoiliac aneurysms (AIAs). METHODS From 1992 to 2000, 154 patients with abdominal aortic aneurysms (n = 66), iliac(More)
Autologous saphenous vein (ASV) and polytetrafluoroethylene (PTFE) grafts were compared in 845 infrainguinal bypass operations, 485 to the popliteal artery and 360 to infrapopliteal arteries. Life-table primary patency rates for randomized PTFE grafts to the popliteal artery paralleled those for randomized ASV grafts to the same level for 2 years and then(More)
Correction of symptomatic vascular steal distal to an arteriovenous fistula requires either fistula ligation or banding. Ligation carries the obvious disadvantage of destruction of a functioning angioaccess, whereas banding procedures have been plagued by the complexity of many of the reported techniques and by the difficulty of balancing fistula flow with(More)
BACKGROUND Advanced glycation endproducts (AGEs) are implicated in the pathogenesis of atherosclerotic vascular disease of diabetic and nondiabetic etiology. Recent research suggests that advanced glycation of ApoB contributes to the development of hyperlipidemia. AGE-specific receptors, expressed on vascular endothelium and mononuclear cells, may be(More)
Although advanced age has often been a relative contraindication to attempts at limb salvage, we have not regarded it as an important deterrent to arterial reconstruction. Our 6-year experience with 168 consecutive patients over 80 years of age who underwent arterial reconstruction or percutaneous transluminal angioplasty represented 18% of all patients(More)
Frey's syndrome after carotid endarterectomy (CEA) is due to iatrogenic injury to the auriculotemporal nerve and has not been previously reported. One month after uncomplicated CEA, our patient noted an erythematous flush and copious drainage of clear fluid from the superior portion of his neck wound whenever he ate, or smelled or thought of food. These(More)
We have used a simple reproducible method to measure total outflow resistance (OR) and its proximal and distal components in 101 bypasses (46 femoropopliteal [FP] and 55 femorodistal [FD]). All bypasses with a distal OR greater than 1.2 mm Hg/ml/min failed within 3 months and all with distal OR less than 1.2 mm Hg/ml/min remained patent for at least 3(More)
