Stereotactic endovascular aortic navigation with a novel ultrasonic-based three-dimensional localization system.

Background: Endovascular aortic procedures have been developed to treat many aortic diseases effectively. However, these procedures are also becoming increasingly complex given the development of branched or fenestrated endografts. Part of the difficulty lies in the limitations of current imaging paradigms.

A prospective study of carbon dioxide digital subtraction versus standard contrast arteriography in the detection of endoleaks in endovascular abdominal aortic aneurysm repairs.

Background: The objective of this study is to compare intraoperative endoleak detection by carbon dioxide digital subtraction angiography (CO(2)-DSA) during endovascular aortic aneurysm repair (EVAR) with standard iodinated contrast angiography (ICA).

Methods: Between 2006 and 2010, 76 patients with abdominal aortic aneurysms undergoing EVAR were enrolled in a prospective study. After EVAR, both an ICA and CO(2)-DSA completion study were performed.

Safety of carbon dioxide digital subtraction angiography.

Objective: Reports of fatality following carbon dioxide digital subtraction angiography (CO2-DSA) have raised concerns regarding its safety. This study reviews the safety of CO2-DSA.

Design: Single-institution retrospective review.

Symptomatic 7-cm abdominal aortic aneurysm in an otherwise healthy 31-year-old woman.

Abdominal aortic aneurysms are rare in young women. We report the case of a 31-year-old woman who underwent open surgical repair of a symptomatic 7-cm abdominal aortic aneurysm (AAA). The patient had no identifiable AAA risk factors.
