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.

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 ReportsRuptured left gastric artery aneurysm: unique presentation with hemothorax and hemomediastinum.
Although splanchnic artery aneurysms are uncommon and remain mostly asymptomatic, they are associated with a high mortality rate when they rupture. We discuss the case of a 66-year-old woman who had successful embolization of a left gastric artery aneurysm after presenting with acute chest pain and the unusual computed tomography findings of hemothorax and hemomediastinum. To our knowledge, only one other similar case has been published in the literature.
