Case ReportsSuperior mesenteric artery pseudoaneurysm associated with celiac axis occlusion treated using endovascular techniques.
The case of a 30-year-old woman with a post-traumatic pseudoaneurysm of the superior mesenteric artery and associated celiac axis occlusion is presented. The patient was successfully treated with celiac artery recanalization and placement of a covered stent within the superior mesenteric artery. Follow-up at 3, 6, and 12 months and 3 years demonstrated patency of the covered stent and continued exclusion of the aneurysm. Although the long-term success of this procedure is unknown this management option should be considered where facilities are available, to reduce the increased morbidity associated with open surgical procedure.

Comparative StudyVariations of patient doses in interventional examinations at different angiographic units.
We analyzed doses for various angiographic procedures using different X-ray systems in order to assess dose variations. ⋯ Interventional radiologists should measure patient doses for their examinations. If there is a lack of necessary instrumentation for this purpose, then published dose reports should be used in order to predict the dose levels from some of the exposure parameters. Patient dose information should include not only the measured quantity but also the measured radiation output of the X-ray unit and exposure parameters used during radiographic and fluoroscopic exposures.

The purpose of the study was to assess the clinical safety and efficacy of the "Recovery(TM)" (Bard) inferior vena cava (IVC) filter. We retrospectively evaluated the clinical and imaging data of patients who had a "Recovery(TM)" IVC filter placed between January 2003 and December 2004 in our institution. The clinical presentation, indications, and procedure-related complications during placement and retrieval were evaluated. ⋯ During clinical follow-up, 12 of 96 patients developed symptoms of PE and only 1 of the 12 had PE on CT. There was no fatal pulmonary embolism in our group of patients following "Recovery" filter placement. However, the current version of the filter is associated with structure weakness, a high incidence of IVC wall penetration, and asymmetric deployment of the filter legs.

Case ReportsBenign mature mediastinal dysembryoma with pulmonary extension revealed by recurrent hemoptysis in a young woman.
We report one case of mature mediastinal teratoma with pulmonary extension surgically diagnosed in a 22-year-old woman complaining of recurrent hemoptyses for which no etiological explanation could be found. Thoracic surgery was only decided on after three embolizations proved ineffective.
