Selective delivery of low-dose streptokinase was effective in the treatment of embolic occlusion of the celiac and superior mesenteric arteries. The two-catheter technique resulted in complete lysis of clot in the celiac artery and improvement in patency of the superior mesenteric artery. The procedure restored effective mesenteric blood flow and provided(More)
Fungal intravascular graft infections are rare. In addition to our case, which forms the basis of this article, only 13 documented instances could be found in the literature in the 20-year period from 1966 to 1986. Three of these cases (21%) had both fungus and bacteria grown in culture. Candida and Aspergillus species constituted most of the infecting(More)
Well known complications of polytetrafluoroethylene (PTFE) grafts include thrombosis, infection, and pseudoaneurysms. Chronic perigraft seromas (CPS) associated with knitted dacron grafts are well described but only sporadic cases have been described in conjunction with PTFE grafts. In order to document the clinical history of PTFE associated CPS, 1674 PTFE(More)
Lower extremity bypass grafts to the tibial and crural arteries are commonly employed to treat patients with atherosclerotic limb-threatening ischemia. Although occasional series have mentioned bypasses to a plantar artery, few of these specifically examine the results of arterial reconstructions using these vessels. Six patients underwent femoral to(More)
The advantages of tube versus bifurcation graft replacement of abdominal aortic aneurysms are well known, yet the risk of future development of iliac occlusive or aneurysmal disease still leads many to use bifurcation grafts routinely. Several studies have reported little risk of this development when patients are followed clinically. They suffer, however,(More)
Surgeons share their challenges and dilemmas in making ethical decisions in these twelve personal stories. The three commentary articles draw out the lessons the stories address. The commentators come from diverse backgrounds including sociology, bioethics, nursing, and surgery.
Autogenous vein remains the conduit of choice for lower extremity revascularization. When a large or dilated vein is used in a reversed manner, there may occasionally be a large size discrepancy between it and a small tibial artery. A technique is presented that reduces this mismatch and facilitates anastomoses between large veins and small arteries.
The functional capacity of the Superficial Palmar Arch (SPA) was evaluated in 200 normal hands by a non-invasive narrow beam ultrasonic technique. Peak systolic velocity of flow with radial artery occlusion increased in all SPAs except for 22 (11%) which were considered incomplete. Ulnar artery occlusion resulted in a more variable response including 89(More)
