Severe stenosis/occlusion of the proximal celiac trunk due to median arcuate ligament compression (MALC), arteriosclerosis, pancreatitis, tumor invasion, and celiac axis agenesis has been reported. However, clinically significant ischemic bowel disease attributable to celiac axis stenosis/occlusion appears to be rare because the superior mesenteric artery(More)
BACKGROUND Potential drawbacks of percutaneous radiofrequency ablation (RFA) for renal cell carcinoma (RCC) include local recurrence after RFA due to a limited ablation area, massive hemorrhage induced by kidney puncture, and difficulty in visualizing the tumor at CT-guided puncture. PURPOSE To evaluate retrospectively the technical success,(More)
BACKGROUND Hepatic percutaneous radiofrequency ablation (RFA) is usually performed with the patient under deep intravenous (i.v.) sedation or general anesthesia. Nonetheless, many patients report pain during and/or after the procedure. PURPOSE To perform a prospective study of pain control obtained by the i.v. one-shot delivery and the continuous i.v.(More)
We applied multivariate analysis to the clinical findings in patients with acute gastrointestinal (GI) hemorrhage and compared the relationship between these findings and angiographic evidence of extravasation. Our study population consisted of 46 patients with acute GI bleeding. They were divided into two groups. In group 1 we retrospectively analyzed 41(More)
PURPOSE To describe our experiences with the treatment of visceral artery aneurysms (VAA) by transcatheter coil embolization and to propose indications for treating VAA by this method. METHODS We treated 22 patients with VAA by coil embolization; 9 had splenic-, 7 renal-, 4 pancreaticoduodenal arcade-, and 2 proper hepatic artery aneurysms. All nine(More)
A 56-year-old man with acute myeloleukemia was hospitalized for lumbar pain. Treatment with antibiotics failed to improve the symptoms. For the diagnosis of infiltration by leukemia we performed CT-guided percutaneous needle biopsy of the L2-L3 disc and the L3 vertebral body using a left posterolateral approach. His symptoms were improved by treatment with(More)
Aneurysms of the pancreaticoduodenal artery are rare. Degeneration of pancreaticoduodenal arcade vessels due to these aneurysms is associated with celiac artery stenosis or occlusion. Untreated lesions enlarge progressively and may rupture spontaneously. As the location of aneurysms of pancreaticoduodenal arcade vessels renders their surgical extirpation a(More)
PURPOSE To describe our experiences with treatment of visceral artery pseudoaneurysms (VAPA) by transcatheter coil embolization using an isolation technique and to propose indications for treating VAPA with this method. MATERIALS AND METHODS We treated 37 patients with VAPA endovascularly: There were 15 pancreaticoduodenal arcade, 10 hepatic, 5 renal, 3(More)
PURPOSE To compare computed tomography (CT)-guided percutaneous biopsy with and without registration of prior positron emission tomography (PET)/CT images in the diagnosis of mediastinal tumors. METHODS We performed clinically indicated percutaneous biopsy in 106 patients with mediastinal tumors in the anterior (n = 61), posterior (n = 21), middle (n =(More)
RATIONALE AND OBJECTIVES We evaluated the effect of gravity on intrahepatic perfusion (IHP) in patients with a port-catheter system (PCS) implanted for hepatic arterial infusion chemotherapy (HAIC). Using fused single photon-emission computed tomographic (SPECT)/computed tomographic (CT) images, we compared IHP after the injection of technetium-99m-labeled(More)
