Thoracic endovascular aortic repair with aortic arch vessel revascularization

Abstract

Background: Revascularization of aortic arch vessels was performed with thoracic endovascular aortic repair (TEVAR) to preserve the endoprosthesis landing zone in 19 high-risk patients.

Methods: The operative procedure used was a bypass or transposition involving the common carotid and subclavian arteries. Homemade fenestrated stent-grafts, deployed in landing zone 0, were used for TEVAR.

Results: All lesions resolved without endoleaks. No perioperative deaths occurred; seven patients had postoperative complications. One patient with acute respiratory distress syndrome required reoperation to change the bypass route and permit tracheostomy. One patient died of pneumonia 2 months after treatment, after an anastomotic pseudoaneurysm and cerebral infarction developed and an operation was performed to obtain hemostasis. The procedure-related mortality was 5.3%.

Conclusion: Aortic arch vessel revascularization before TEVAR may permit less invasive surgery, although careful patient selection is essential.
