PURPOSE To study fluoroscopic placement of covered expandable stent tubes in patients with esophagogastric strictures. MATERIALS AND METHODS Under fluoroscopic guidance, 132 stent tubes were placed in 116 patients with malignant neoplasm; four, in three patients with benign lesions. All patients had aphagia or dysphagia to soft food or liquid. RESULTS(More)
BACKGROUND Advances in imaging techniques have increased the recognition of aortic intramural hematomas (IMHs) and penetrating atherosclerotic ulcers (PAUs); however, distinction between IMH and PAU remains unclear. We intended to clarify differences between IMH coexisting with PAU and IMH not associated with PAU by comparisons of clinical features, imaging(More)
A self-expanding silicone-covered tube constructed of Gianturco stents was used for palliative treatment of esophagorespiratory fistula related to esophageal carcinoma in eight patients. All eight were unable to swallow food or water before treatment. The tubes were inserted under fluoroscopic guidance, without technical failure or complication. Clinical(More)
PURPOSE To propose a modified angiographic classification for peripheral arteriovenous malformations (AVMs) and to determine its value for assessing therapeutic outcomes and approaches to ethanol embolization of AVMs in the body and extremities. METHODS AVMs of the trunk and extremities were categorized according to the angiographic morphology of the(More)
Early diagnosis and treatment of Takayasu arteritis is important in prevention of serious complications. Spin-echo magnetic resonance imaging (MRI) can depict early wall thickening of the aorta and cine MRI can evaluate aortic valve function. Significant enhancement in and around the aorta and carotid arteries is observed on postcontrast MR images in acute(More)
PURPOSE To assess retrospectively the therapeutic results, complications, and therapeutic approach to ethanol embolotherapy of extremity arteriovenous malformations (AVMs) involving the bone. MATERIALS AND METHODS From December 1996 to May 2009, 22 patients (12 male, 10 female; eight children, 14 adults; age range, 1-64 years) with extremity AVMs(More)
PURPOSE To assess the usefulness of flexible covered metallic stents in the palliation of malignant obstruction of the gastric outlet and duodenum. MATERIALS AND METHODS Twenty-four consecutive patients with malignant obstruction of the gastric outlet (n = 22) or duodenum (n = 2) underwent palliative treatment with self-expandable flexible covered(More)
PURPOSE To evaluate the usefulness of flexible covered stents for treatment of acute colorectal obstruction secondary to malignant colorectal carcinoma. MATERIALS AND METHODS Twenty patients with acute colorectal obstruction secondary to malignant colorectal carcinoma were treated by means of intubation of a flexible stent with fluoroscopic guidance with(More)
PURPOSE This paper is an update of previously published data on the basis of a retrospective review of midterm results of ethanol sclerotherapy on 87 patients (January 1995 to December 2000) for assessment of its efficacy as an improved treatment method for venous malformation (VM). According to this assessment, VMs were defined with a new classification(More)
PURPOSE To evaluate the long-term effectiveness of expandable esophageal metallic stents in benign esophageal strictures. MATERIALS AND METHODS The authors performed long-term follow-up of 14 expandable metallic stents in 12 patients (aged 16-72 years) with benign esophageal strictures. All 12 patients had initially undergone placement of one stent; two(More)
