Endovascular (stent-graft)-assisted open vascular anastomosis.

Endovascular and open surgical approaches are an integral part of treating patients with complex vascular disease and are often considered separately. In some situations, traditional open surgical techniques can be used to facilitate an endovascular approach, as example: iliac conduit use for EVAR/TEVAR, subclavian or axillary conduits for complex endovascular aortic repairs (chimney, B-FEVAR), and bypass to great vessels or visceral artery (celiac, superior mesenteric and renal arteries) debranching. As devices and techniques evolve, the open and endovascular approaches can be utilized in more complimentary fashion. This paper describes the use of endovascular procedures to assist difficult open surgical situations such as iliofemoral bypass, aortic arch debranching involving the left subclavian artery, and distal right iliac artery management during open thoracoabdominal aortic aneurysm (TAAA) repair.
