OBJECTIVE Transfemorally placed endoluminal grafts are currently being evaluated as an alternative to open surgery for the treatment of abdominal aortic aneurysms. We determined the value of helical CT for the follow-up of patients treated with this new procedure. The purposes of this study were to determine CT features of a technically successful(More)
PURPOSE Hypogastric artery embolization is considered to be necessary to prevent retrograde flow and potential endoleaks when a stent-graft crosses the origin of the hypogastric artery. The authors assess the incidence of buttock claudication, which is the primary complication encountered. The effect of coil location and the presence of antegrade flow at(More)
BACKGROUND Intra-arterial thrombolytic therapy is currently a therapeutic option for the treatment of acute limb ischemia. A recent large prospective randomized trial (TOPAS) comparing lytic therapy and operative intervention showed that both forms of treatment had similar results in terms of amputation-free survival. However, the exact role for lytic(More)
Functional and anatomic evaluation of penile arterial blood flow is essential in the work up of erectile dysfunction. Duplex ultrasonography is an ideal screening modality with cavernosal mean peak systolic blood flow velocity being the most sensitive predictor of arterial disease. Arterial variability of the penis may affect sonographic evaluation leading(More)
PURPOSE Significant disease or occlusion of the common femoral artery may preclude percutaneous therapy for aorto-iliac occlusive disease. In addition, aorto-iliac angioplasty may not reverse the ischemic symptoms when common femoral artery disease exists. The authors describe the feasibility of endoluminal stent-grafts to treat multilevel aortoiliofemoral(More)
An upper gastrointestinal bleed is defined as hemorrhage proximal to the ligament of Treitz and is most commonly due to peptic ulcer disease, gastritis, Mallory-Weiss tears, and varices. Less common etiologies of bleeding include tumor or iatrogenic causes such as hemobilia due to liver biopsy. Since the most frequent etiology is benign peptic ulcer disease(More)
traveling at slow speeds can produce vascular injuries usually confined to the wound tract. These injuries can include lacerations, contusions, punctures, and transections. High-velocity bullet injuries can cause both direct and remote damage due to the disruption of surrounding tissues by the bullet energy. Contusions or vessel transection can occur. If(More)
