Direct Abdominal Aortic Access for Thoracic Endovascular Aortic Repair in a Patient with Severe Aortic and Arterial Calcification.

ABSTRACT

Aortic and arterial calcification is a complication of advanced atherosclerosis and is a critical intraoperative issue that can reduce the ability to achieve safe and adequate access for stent graft introduction. Different vascular access sites are used to deliver stent grafts when a standard transfemoral or iliac access is not feasible. We report a challenging case of a direct transabdominal aortic thoracic endovascular aortic repair for a thoracic aortic aneurysm complicated with severe aortic and arterial calcification, in which the noncalcified area of the infrarenal abdominal aorta was extremely limited. This may be a reasonable access site, especially for patients with severe aortic and arterial calcification.
