BACKGROUND Transjugular placement of an intrahepatic stent is a new technique to establish a portosystemic shunt for treatment of portal hypertension. A puncture needle is advanced in a catheter through the inferior vena cava into a hepatic vein; then an intrahepatic branch of the portal vein is punctured and an expandable stent of metallic mesh is(More)
Painful osteoporotic and malignant vertebral fractures are frequent causes of chronic back pain with negative consequences regarding immobility, quality of life, morbidity, mortality, and fracture incidence. The best currently available evidence-based treatment reduces vertebral fracture risk but does not totally prevent follow-up fractures. Kyphoplasty is(More)
Previously, we reported significantly reduced pain and improved mobility persisting for 6 months after kyphoplasty of chronically painful osteoporotic vertebral fractures in the first prospective controlled trial. Since improvement of spinal biomechanics by restoration of vertebral morphology may affect the incidence of fracture, long-term clinical benefit(More)
OBJECTIVE To compare maximum spatial resolution in multislice computed tomography (MS-CT) and digital subtraction angiography (DSA) using an arterial tree model for canine kidney specimens. METHODS Twenty-three isolated fox terrier kidneys were catheterized with a 4F catheter and underwent contrast-enhanced MS-CT with a maximum spatial resolution of(More)
PURPOSE Kyphoplasty immediately improves pain and mobility in patients with painful osteoporotic vertebral fractures, but long-term clinical outcomes are still unclear. This controlled trial evaluates pain, mobility and fracture incidence 3 years after kyphoplasty. MATERIALS AND METHODS Kyphoplasty was performed in 40 patients with painful osteoporotic(More)
OBJECTIVE To evaluate the accuracy of multidetector computed tomography (CT) and magnetic resonance imaging (MRI) in staging and estimating renal carcinomas with caval thrombus. METHODS Initially, 23 patients with suspected caval thrombi were admitted into this prospective study. Triphasic CT imaging was performed using a multidetector CT with a(More)
Balloon-expandable intraluminal stents were used to treat iliac artery stenoses or occlusions that failed to respond to conventional balloon angioplasty. One hundred seventy-one procedures were performed in 154 patients, of whom 48 had a limb at risk for amputation. Thirty-six had severe and 70 had moderate intermittent claudication. At the latest follow-up(More)
QUESTION Can the same levels of pain reduction and increase in function be achieved in kyphoplasty procedures with Calcibon as with polymethylmethacrylate (PMMA) cement? PATIENTS AND METHODS In a prospective, interdisciplinary single-center study, 99 patients (173 vertebral fractures) were treated with kyphoplasty. Augmentation was performed with PMMA in(More)
Fifteen patients with symptomatic iliac artery stenosis were treated with intraluminal placement of balloon-expandable stents. Before treatment, 14 patients had intermittent claudication, and one had a limb at risk for amputation. One patient had diabetes mellitus, nine had hypertension, and all were long-term smokers. Two patients had surgical placement of(More)
