OBJECTIVE To our knowledge, ours is the largest single-center experience with diagnosis and management of acute arterial hemorrhagic and limb-threatening ischemic complications associated with total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS Between 1989 and 2002, 23,199 TKA procedures (13,618 total, 11,953 primary, 1665 revision)(More)
True aneurysm of the subclavian artery is extremely rare. Excluding the more common aneurysms of an aberrant right subclavian artery, those associated with thoracic outlet syndrome, and posttraumatic "aneurysms," atherosclerosis is the most common cause. Syphilis, tuberculosis, and cystic medial necrosis are less often the cause. These aneurysms can(More)
OBJECTIVE Early in our experience with endovascular aortic aneurysm repair (EVAR) we performed both serial computed tomography scans and duplex ultrasound (DU) imaging in our post-EVAR surveillance regimen. Later we conducted a prospective study with DU imaging as the sole surveillance study and determined cost savings and outcome using this strategy. (More)
PURPOSE The North American Subfascial Endoscopic Perforator Surgery (NASEPS) Registry was established to evaluate the safety, feasibility, and efficacy of minimally invasive endoscopic Linton operations for treatment of chronic venous insufficiency. METHODS Retrospective analysis was performed on the clinical data of 151 patients who underwent attempt at(More)
Recognizing the impact of the decision making by the dialysis access surgeon on the successful placement of autogenous arteriovenous hemodialysis access, the Society for Vascular Surgery assembled a multispecialty panel to develop practice guidelines in arteriovenous access placement and maintenance with the aim of maximizing the percentage and(More)
PURPOSE The objective of this study was to compare clinical outcome and costs for two widely used treatment strategies for hemodialysis graft thrombosis. METHODS During a 4-year period, 80 patients with thrombosed dialysis grafts were randomly assigned to surgical thrombectomy with or without graft revision (SURG) or thrombolytic therapy with urokinase(More)
Spontaneous dissection of the superior mesenteric artery (SMA) is rare. We report a case of rupture of the SMA after spontaneous dissection in a 51-year-old male who presented with acute onset of abdominal pain and hypotension. The patient was initially treated with intravenous fluid resuscitation and endovascular intervention followed by open surgery. No(More)
Three unusual cases of an abdominal aortic aneurysm spontaneously rupturing into the retroperitoneum and an adherent posterior vein are reported. No patient demonstrated signs or symptoms of an aortovenous fistula before surgery. Emergent surgery prevented extensive preoperative diagnostic testing. The three abdominal aortic aneurysms were very large and(More)
BACKGROUND Total graft excision with in situ or extra-anatomic revascularization is considered mandatory to treat infection involving the body of aortic grafts. We present a series of nine patients with this complication and such severe comorbid medical illnesses or markedly hostile abdomens that traditional treatments were precluded. In these patients(More)
The Society for Vascular Surgery (SVS) appointed a committee of experts to formulate evidence-based clinical guidelines for the management of carotid stenosis. In formulating clinical practice recommendations, the committee used systematic reviews to summarize the best available evidence and the GRADE scheme to grade the strength of recommendations (GRADE 1(More)
