Endovascular repair of extent I thoracoabdominal aneurysms with landing zone extension into the aortic arch and mesenteric portion of the abdominal aorta

Thoracic endovascular aortic repair (TEVAR) has emerged as an alternative for patients at prohibitive risk for open thoracic or thoracoabdominal surgery, decreasing perioperative morbidity and mortality. Aneurysms that involve both the left subclavian artery (LSA) proximally and the celiac artery (CA) distally present a unique challenge to the use of TEVAR. We report a series of six high-risk patients presenting with extent I thoracoabdominal aortic aneurysms who were successfully treated with TEVAR including coverage of the LSA and the CA.
