PURPOSE Underdeployment of an intravascular stent has been identified as a cause of restenosis or occlusion of a treated arterial lesion. Intravascular ultrasound (IVUS) has been shown to initially improve the anatomic and clinical stenting. The purpose of this study was to determine whether the use of IVUS increased long-term patency of this intervention.(More)
BACKGROUND Planned reductions in reimbursement for all forms of vascular surgery dictate a need for the development of more cost efficient, yet quality oriented, treatment programs. We are faced with an increasingly older patient population with multiple comorbidities. In this environment it will become extremely difficult to accomplish aortic surgery in a(More)
PURPOSE Cryopreserved saphenous vein allografts are used for femoral-infrapopliteal bypass graft purposes when adequate autogenous vein is unavailable. Anticoagulation, immunosuppression therapy, or both have been suggested means for improving allograft patency. Immunosuppression has significant cost and morbidity and has produced variable results. Our(More)
BACKGROUND Carotid endarterectomy (CEA) is the standard of care for patients with high-grade carotid artery stenosis who are acceptable surgical candidates. Focal occlusive lesions of the origin of aortic arch vessels can be effectively and safely treated with balloon angioplasty and primary stenting. The purpose of this study was to retrospectively review(More)
BACKGROUND The optimal therapy for TransAtlantic Societal Consensus (TASC) type C femoropopliteal lesions remains a critical issue in the treatment of infrainguinal occlusive disease. The purpose of this study was to evaluate the outcome of limbs with TASC C femoropopliteal lesions and critical limb ischemia treated with the FoxHollow SilverHawk atherectomy(More)
BACKGROUND Mobile atheromas of the aortic arch are associated with otherwise unexplained strokes and transient ischemic attacks (TIA). They are associated with increased perioperative strokes in patients undergoing coronary artery bypass surgery. Peripheral embolization is an additional risk. Transesophageal echocardiography (TEE) accurately identifies(More)
The purpose of this study is to describe the advantages and value of an endovascular suite in the operating room from a vascular surgeon's perspective. All endovascular procedures were performed in a specially equipped operating room by vascular surgeons using digital fluoroscopic imaging equipment. Between January 1, 1994 and August 31, 1996,(More)
The proximal 4 mm of the Gore Excluder endoprosthesis are scalloped. Our purpose is to describe our initial experience of a novel technique, referred to as the "endowedge," that takes advantage of this scalloped configuration in aneurysms with short proximal necks. The technique utilizes a balloon in the renal artery to aid alignment of a scallop and allow(More)
PURPOSE This study was undertaken to determine whether the use of intravascular ultrasound (IVUS) during balloon angioplasty and stenting of atherosclerotic aortoiliac occlusive lesions improved long-term clinical outcome. IVUS has been previously shown to be more accurate than arteriography in evaluating the deployment of stents in both peripheral and(More)
This case report details the multidisciplinary treatment of peripartum left iliac vein thrombosis using percutaneous catheter-directed urokinase thrombolysis and balloon thromboplasty. Enhanced chances for long-term patency and the normalization of venous function make these minimally invasive procedures accepted options for the treatment of iliofemoral(More)
