PURPOSE Surgical management of carotid restenosis (CR) after carotid endarterectomy (CEA) has been associated with a higher perioperative complication rate than that of primary CEA. We recently used carotid angioplasty-stenting (CAS) as an alternative to operative management in patients who had undergone CEA within three years, and we retrospectively(More)
PURPOSE We studied the efficacy of preoperative noninvasive assessment of the upper extremity to identify arteries and veins suitable for hemodialysis access to increase our use of autogenous fistulas (AF). METHODS From Sep. 1, 1994, to Apr. 1, 1997, 172 patients who required chronic hemodialysis underwent segmental upper extremity Doppler pressures and(More)
The treatment of symptomatic congenital hepatic cysts is surgical. Aspiration does not provide definitive therapy and carries a high recurrence rate. Surgical exploration and drainage intraperitoneally, externally, and internally to a segment of bowel have been described. With the recent explosion in the applications of laparoscopic guided surgery, we(More)
Polytetrafluoroethelene (PTFE) is often utilized in patients with limb-threatening ischemia requiring infrainguinal revascularization in the absence of autologous saphenous vein. To increase long-term patency of PTFE grafts, vein interposition cuffs have been recommended as adjunctive procedures. The purpose of this study was to assess the efficacy of vein(More)
A 72-year-old male patient presented with a thrombosed popliteal artery aneurysm measuring 15 x 8 cm 12 years following ligation and saphenous vein bypass grafting through a medial approach. The giant aneurysm, which had grown and compressed the previously functional vein bypass graft to the point of graft thrombosis, was causing a knee contracture that(More)
PURPOSE Chronic venous insufficiency (CVI) and varicose vein (VV) formation is characterized histologically by the transformation of smooth muscle cells (SMC) from a contractile to a secretory phenotype and by intense collagen deposition. The subcellular regulation point for these processes may be the retinoblastoma protein (pRb), a known inhibitor of(More)
