PURPOSE To determine prospectively the incidence of adverse events in angiography related to contrast agents, and the relative incidence of events with use of high-osmolality contrast agents (HOCAs) and low-osmolality contrast agents (LOCAs) and to ascertain if risk factors can help identify increased risk of an adverse event and patients likely to benefit(More)
Two forms of priapism are known to occur. The more common type, veno-occlusive priapism, presents with a prolonged painful erection, and it is characterized by ischemia and pooling of blood within the corpora cavernosa. The less common form, high flow priapism, is characterized by lack of pain and ischemia. The pathophysiology of this disorder is poorly(More)
Histological examination of oesophageal rings removed at transection for varices reveals dilated intraepithelial blood filled channels. These are present in all oesophageal rings removed at transection for varices. A comparison has been made between rings removed from variceal patients with oesophageal rings removed during resections for oesophageal and(More)
OBJECTIVE Despite well-documented good early results and benefits of endoluminal stent graft repair of abdominal aortic aneurysm (J Vasc Surg 2002;35:1137-44.)(AAA), the long-term outcome of this method of treatment remains uncertain. In particular, concern exists that late effectiveness and durability are inferior to that of open repair. To determine the(More)
Four patients with intrahepatic arterial aneurysms were treated with transcatheter embolization. Two patients had multiple aneurysms, and two had single aneurysms; in two the aneurysms were post-traumatic, and in the other two they were mycotic. Either Gelfoam or isobutyl-2-cyanocrylate was used to occlude the hepatic artery branches. It is concluded that(More)
PURPOSE To assess the clinical safety and efficacy of suprarenal inferior vena cava (IVC) filters during long-term follow-up. MATERIALS AND METHODS In this retrospective study, the authors collected the following data about patients who underwent suprarenal IVC filter placement at their institution between 1988 and 2007: demographics, clinical(More)
PURPOSE We investigated 2 evolving concepts in the management of arterial priapism: 1) the efficacy of perineal duplex Doppler ultrasound as a diagnostic alternative to arteriography and 2) the therapeutic alternative of expectant management. MATERIALS AND METHODS We evaluated 10 patients with high flow arterial priapism. RESULTS Compared to selective(More)
To determine the presence, location and pattern of arterial occlusive disease within the hypogastric-cavernous arterial bed in impotent men following blunt perineal and pelvic trauma, we reviewed the selective internal pudendal arteriograms of 20 patients with a history of blunt perineal and 7 with blunt pelvic trauma who had immediate development of(More)
Selective internal pudendal angiography was performed in 195 men (average age, 35.4 years +/- 10.3) who were suspected of having arteriogenic impotence. In the majority of patients, disease was localized to the cavernosal arteries. A previous series that involved older patients had demonstrated significant disease in the hypogastric and internal pudendal(More)
PURPOSE We reviewed our initial thoracic aorta (TA) stent graft experience in 28 patients from the perspective of treatment with homemade devices (Dacron over Gianturco Z stents; 14 cases) and a commercial device (Excluder; W.L. Gore Co, Flagstaff, Ariz; 14 cases). METHODS From November 1996 to August 2001, 28 patients with a spectrum of disease(More)
