Two young women with renal angiomyolipomas (AML) containing solitary large aneurysms are presented. In both patients AML was complicated by life-threatening hemorrhage. In the first case a parenchymal sparing procedure was undertaken (heminephrectomy). The second case was treated with interventional radiologic techniques with excellent results despite(More)
Crohn's disease of the colon and small bowel is associated with a greater-than-chance increased incidence of adenocarcinoma, which also differs from the norm in age and anatomic distribution. The cancer risk appears to rise with earlier age of onset and long duration of the granulomatous disease, and the prognosis is relatively poor, probably due to(More)
Pedal arch integrity can be determined morphologically and functionally. The former is accessible by contrast studies and intraoperative catheterization, the latter, by flow studies and observation of graft patency. The roengten image of an intact pedal arch corresponds to the anatomic plantar arch. Sixty-four arch studies obtained by adequate(More)
Standard contrast arteriography (SCA) and intra-arterial digital subtraction arteriography (DSA) were performed during a 26-month period in 459 cases. The DSA group consisted of 22 aortoiliac studies, 66 crural-pedal arch studies, and 227 combinations. In addition, postoperative DSA was performed in 42 patients to evaluate graft patency, morphology, and(More)
Renal vein thrombosis is a complication of the nephrotic syndrome presumably related to compression of renal veins by edematous parenchyma and a concomitant hypercoagulable state. The diagnosis has been made by demonstrating marked widening of the left renal vein as it crosses horizontally anterior to the aorta on computed tomography. Inferior(More)
Intra-arterial thrombolysis with streptokinase was studied in 38 patients. The indications were peripheral thromboembolism in nine patients (group 1), postreconstruction graft thrombosis in 26 patients (group 2) and renal artery thrombosis in three patients (group 3). The intra-arterial route was used for the first and third groups and in 16 of the second(More)
