Comparison of arterial closure devices in antegrade and retrograde punctures.

Purpose: To compare the efficacy, primary failure rates, and complications for the Angio-Seal and Perclose closure devices in antegrade and retrograde common femoral artery (CFA) punctures during peripheral angioplasty procedures.

Methods: A retrospective single-center analysis was conducted between April 2002 and June 2006 of all patients who had a CFA puncture and no other intervention planned during the same admission. Patients undergoing thrombolysis were excluded.

CT virtual intravascular endoscopy in the visualization of fenestrated stent-grafts.

Purpose: To report the diagnostic value of computed tomographic (CT) virtual intravascular endoscopy (VIE) in the assessment of patients with abdominal aortic aneurysm (AAA) treated with fenestrated endovascular grafts.

Methods: Eight patients (7 men; mean age 76 years, range 70-82) with AAAs unsuitable for open surgery or conventional endovascular repair had fenestrated endovascular grafts implanted. Both pre- and post-fenestration multislice CT data were used to generate VIE images of the visceral artery ostia and the side branch fenestrated stents.
