OBJECTIVE This study was designed to define and evaluate a specific index to quantify arterial obstruction with helical CT in acute pulmonary embolism. MATERIALS AND METHODS Fifty-four patients (mean age, 56 years) with proven pulmonary emboli among 158 consecutive patients, who had undergone both CT and pulmonary angiography for clinically suspected(More)
PURPOSE To identify predictors of clinical outcome after arterial embolotherapy for upper gastrointestinal (UGI) hemorrhage. MATERIALS AND METHODS Seventy-five consecutive patients (mean age, 62.5 y) underwent arterial embolization for acute UGI hemorrhage. Bleeding was detected at endoscopy and angiography in 22 patients, at endoscopy alone in 29(More)
Venous malformations are the most common vascular malformations. However, confusion with respect to terminology and imaging guidelines continues to result in improper diagnosis and treatment. An appropriate classification scheme for vascular anomalies is important to avoid the use of false generic terms. Adequate imaging in association with clinical(More)
PURPOSE To report data collected by the Canadian Registry of the Günther Tulip Retrievable Filter (GTF). MATERIALS AND METHODS Between February 1998 and December 2000, 90 patients at eight hospitals underwent implantation of 91 GTFs. There were 45 male patients and 45 female patients, age 17-88 years, with a mean age of 49 years. Indications for filter(More)
PURPOSE To review clinical outcomes of patients with chronic limb ischemia and TASC type C lesions treated with sirolimus-eluting versus bare SMART nitinol self-expanding stents. METHODS Data were obtained from a randomized, multicenter, double-blinded study conducted in 2 phases. All 93 patients had chronic limb ischemia and superficial femoral artery(More)
PURPOSE To evaluate the success, safety, and efficacy of the retrieval of the OptEase Permanent/Retrievable Vena Cava Filter (Cordis, Warren, NJ), when implanted for temporary protection against venous thromboembolism. MATERIALS AND METHODS This prospective, multicenter, non-randomized study enrolled 27 patients who needed temporary protection against(More)
BACKGROUND Stent implantation for obstructive femoropopliteal artery disease has been associated with poor long-term outcomes. This study evaluated the effectiveness of shape memory alloy recoverable technology (SMART) nitinol self-expanding stents coated with a polymer impregnated with sirolimus (rapamycin) versus uncoated SMART Stents in superficial(More)
PURPOSE To evaluate the efficacy and safety of percutaneous renal artery embolization (RAE) of iatrogenic vascular kidney injuries and the effects of RAE on renal function and arterial blood pressure (BP). MATERIALS AND METHODS Over a 12-year period, 50 consecutive patients with severe hemorrhage after iatrogenic arterial kidney injuries underwent RAE.(More)
PURPOSE To assess the safety and technical success of the retrieval of the Recovery G2 filter when implanted for temporary protection against pulmonary embolism. MATERIALS AND METHODS The Recovery G2 inferior vena cava (IVC) filter was placed in 120 consecutive patients between September 2005 and September 2006 in a single center. Patients had deep venous(More)
A stent-graft was placed percutaneously in the right renal artery of a 50-year-old woman with hypertension and a fibromuscular dysplastic lesion consisting of severe stenoses and a 1.5-cm saccular aneurysm with a wide neck. At 1-year follow-up with arteriography, arterial luminal diameter was normal and no aneurysm was depicted. The patient's blood pressure(More)
