The persistent sciatic artery (PSA), first described by Green in 1832, is a rare congenital anomaly resulting from the failure of regression of the sciatic artery during the embryonal period. Diagnosis can be difficult, and life-and limb-threatening complications are well…
Originally described in 1984, failing bypass grafts now include any stenosis or abnormal hemodynamics determined by clinical examination, duplex scanning, or arteriography. Although clinical examination provides an initial assessment for vein graft patency, this approach in isolation fails to identify…
Vascular laboratory surveillance of infrainguinal bypass graft function has evolved to a recommended standard of patient care. The rationale for testing is based on the progressive nature of atherosclerosis and the propensity of both autologous vein and prosthetic conduits to…

Acute, pathologic arterial and graft clot formation can severely compromise distal perfusion beds of the leg and commonly requires immediate treatment. The decrease in distal blood flow and the resultant tissue hypoxia promote thrombus deposition in the small nutrient vessels.…
The role for superficial femoral artery (SFA) endarterectomy, either localized or remote (semiclosed), has assumed a less prominent role in current vascular surgical practice. Though described previously, these techniques have been largely supplanted by the well-established superior results of vein…

The choice of intervention and conduit for lower extremity arterial reconstructions when the ipsilateral greater saphenous vein (GSV) is not present remains controversial. Many reconsider less optimal endovascular interventions, and others opt for use of the contralateral GSV, followed by…
Surgical revascularization for lower extremity arteriosclerotic occlusive disease, manifested by critical limb ischemia (CLI) and life-limiting claudication, has been enhanced by an expanding array of conduit choices. In the absence of a perfect arterial substitute, autologous vein possesses the most…
Options for the treatment of patients with limb-threatening lower extremity ischemia in the setting of multilevel occlusive disease are diverse. An open revascularization with the greater saphenous vein (GSV) in the setting of extensive disease or after failed endovascular approach…
