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.

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.

Case ReportsPercutaneous stent-graft repair of a mycotic pulmonary artery pseudoaneurysm.
Ruptured mycotic pulmonary pseudoaneurysm is a lethal complication. Emergent surgical repair is usually recommended, but still associated with a high mortality rate. We present a patient in whom mycotic pulmonary pseudoaneurysm was a complication after surgical lobectomy 2 weeks earlier. ⋯ Hemostasis was achieved immediately and, under a 4-week antibiotic treatment, patient was transferred to a local hospital for medical care. This case report demonstrates the benefit of minimally invasive endovascular therapy in a critically ill patient. A literature review of the etiology and management of mycotic pulmonary pseudoaneurysm is included.
