BACKGROUND Localized inflammation is a physiological protective response which is generally tightly controlled by the body at the site of injury. Loss of this local control or an overly activated response results in an exaggerated systemic response which is clinically identified as systemic inflammatory response syndrome (SIRS). Compensatory mechanisms are(More)
Pseudoaneurysms are common vascular abnormalities that represent a disruption in arterial wall continuity. Some complications associated with pseudoaneurysms develop unpredictably and carry high morbidity and mortality rates. The advent of new radiologic techniques with a greater sensitivity for asymptomatic disease has allowed more frequent diagnosis of(More)
INTRODUCTION Central (superior vena cava, brachiocephalic, or subclavian) venous stenoses are a major impediment to long-term arteriovenous access in the upper extremities. The optimal management of these stenoses is still undecided. The purpose of this study was to determine the outcomes of primary angioplasty (PTA) vs primary stenting (PTS) in a dialysis(More)
PURPOSE To evaluate the efficacy of hepatic artery percutaneous transluminal angioplasty (PTA) in the treatment of hepatic artery stenosis (HAS). MATERIALS AND METHODS A retrospective analysis was performed of all cases of HAS documented by angiography from January 1995 to June 2003 at the authors' institution. Management was evaluated and long-term(More)
OBJECTIVES The objectives of this study were to examine factors predictive of success or failure after percutaneous angioplasty (PTA) and stenting (S) of the superficial femoral artery (SFA) and to compare the results of PTA/S with a contemporary group of patients treated with femoropopliteal bypass. METHODS A database of patients undergoing PTA and/or S(More)
In the current vascular interventional environment, high restenosis rates have increased awareness of the significance of intimal hyperplasia, a chronic structural lesion that develops after vessel wall injury, and which can lead to luminal stenosis and occlusion. Intimal hyperplasia may be defined as the abnormal migration and proliferation of vascular(More)
BACKGROUND Percutaneous intervention for symptomatic renal artery fibromuscular dysplasia (FMD) has replaced surgical therapy as first-line treatment. This study evaluates the factors that impact long-term anatomic and functional outcomes of endovascular therapy for symptomatic renal artery FMD. METHODS Records of patients who underwent renal artery(More)
BACKGROUND Endoluminal therapy for superficial femoral artery (SFA) occlusive disease is commonplace, but the incidence and outcomes of in situ thrombosis (IST) and distal embolization (DE) have not been well defined. The aim of this study was to examine the impact of IST and DE on long-term outcomes of SFA interventions. METHODS A database of patients(More)
