Extra-anatomic left subclavian artery bypass patency in frozen elephant trunk surgery.

ABSTRACT:

Objective

To explore the advantages and consequences of using an extra-anatomic Dacron bypass in frozen elephant trunk surgery for fast and secure left subclavian artery (LSA) reimplantation.

Methods

Between June 2017 and June 2023, 195 patients were treated using an LSA bypass. All postoperative imaging was reviewed to assess the patency of the bypass grafts. If the LSA bypass was not patent, symptoms of complications and their management were evaluated. Time-to-event analysis was performed to assess bypass patency and time to thrombosis.

Results

Out of 195 LSA bypasses, 183 remained patent during follow-up, for a 5-year patency rate of 91.4%. Prolonged cardiopulmonary bypass duration was associated with poorer graft patency. Eight of the 12 patients with a thrombose
