Endovascular management of iliac rupture during endovascular aneurysm repair.

Background: Inadequate iliac artery diameter, calcification, and tortuosity are associated with increased incidence of iliac injury during abdominal (EVAR) and thoracic endovascular aneurysm repair (TEVAR). Despite careful preoperative assessment and use of iliac conduits, inadvertent iliac rupture is a source of morbidity and mortality. This report details our single-center, 10-year experience with intraoperative iliac artery rupture and describes a successful endovascular salvage technique.

Endovascular thoracic aortic aneurysm repair: evaluating the utility of intravascular ultrasound measurements.

Purpose: To compare intravascular ultrasound (IVUS) and computed tomography (CT) measurements of aortic diameter for the determination of stent-graft sizes used in thoracic endovascular aneurysm repair (TEVAR).

Methods: A retrospective review was conducted of 71 IVUS measurements performed in 33 patients (17 men; mean age 69 years) undergoing endovascular repair for thoracic aortic aneurysm (TAA). For comparison, an inanimate model of the aortic arch and the great vessels was created; 5 independent operators took multiple blinded IVUS measurements.

Intravascular ultrasound aids in the performance of endovascular repair of abdominal aortic aneurysm.

Purpose: The purpose of this retrospective review was to assess the accuracy of aortic measurements with intravascular ultrasound scan (IVUS) compared with computed tomographic (CT) scan and to assess the role of IVUS in the performance of endovascular repair of abdominal aortic aneurysms (AAAs).

Methods: Seventy-eight patients undergoing repair of AAA with the AneuRx stent graft (Medtronic AVE, Inc, Santa Rosa, Calif) underwent measurement with CT scan and IVUS. The initial selection of stent graft size was made on the basis of the CT scan measurements, but the final decision for size was made on the basis of the IVUS measurements.
