The authors report six congenital abnormalities of the inferior vena cava detected on computed tomography (CT). The CT findings of one of these, the left inferior vena cava, have not been previously reported. The embryology of the inferior vena cava and the possible congenital abnormalities that can occur are discussed. Congenital abnormalities of the(More)
Sixty-five sites of arterial gastrointestinal hemorrhage in 63 patients were managed with transcatheter therapy. Arterial vasopressin infusion was attempted primarily for all but three sites; embolization was used in these cases and in those for whom vasopressin infusion failed to control bleeding. The results obtained suggest that this regimen, that is,(More)
Late complications at the repair site of coarctation of the aorta include aneurysms and persistent coarctation. Aneurysms are usually due to failure of the surgical anastomosis and can occur many years after repair. Continued aortic coarctation may be due to either repair failure or failure of the anastomotic site to grow with the patient. Three cases are(More)

The leading causes of trauma to the major craniocerebral vessels include penetrating and non penetrating trauma [1 , 2]. Because the vertebral artery is confined to the incomplete bony canal formed by the successive foramina in the transverse processes of the upper cervical vertebrae, it is less susceptible to penetrating injury than is the carotid artery(More)
The hemodynamic effects of intra-material prostaglandin E1 (PE1) administered via the angiographic catheter were evaluated in 14 patients. Blood flow in the superior mesenteric artery (SMA) after PGE1 infusion was compared with control SMA blood flow as measured by the "spillover" angiographic reflux method, using a specially designed injector/film-changer(More)
Percutaneous catheter biliary decompression was performed in 42 patients with obstructive jaundice. Internal drainage was accomplished in 27 patients (64.3%), and external drainage in 15 patients (35.7%). Serum bilirubin levels decreased at a mean rate of 1.4 mg/dl/day. Tissue diagnosis was obtained by percutaneous aspiration biopsy in nine patients(More)
Thirty-one cases of renal vein thrombosis (RVT) were reviewed retrospectively for clinical laboratory, and radiographic findings. An underlying renal disorder was present in 28 cases, absent in only 3. This supports other evidence that RVT is usually a complication of renal disease rather than a primary event, and that nephrotic syndrome may be due to renal(More)
Two cases of traumatic hemobilia are presented in which hemorrhage was controlled by transcatheter vascular occlusion with stainless steel coils. Embolie therapy was safely performed without liver necrosis, despite the presence of portal hypertension in 1 patient. The technique is a useful alternative to surgery, which did not control hemorrhage in 1 case.
