Sumary of Decreased mortality for patients with complex aortic aneurysms treated by fenestrated-branched endovascular aortic repair:
- The study, “Midterm Outcomes of a Prospective, Nonrandomized Study to Evaluate Endovascular Repair of Complex Aortic Aneurysms Using Fenestrated-Branched Endografts,” led by senior author Gustavo S. Oderich, MD, was published in the September 2021 Annals of Surgeryand presented at the American Surgical Association meeting.
- The device is manufactured to fit the anatomy of the patient with specialized fabric tube “windows” (fenestrations) or side arms (“branches”) supported by a structure of stainless steel or nickel-titanium alloy wires.
- The researchers reported that endovascular repair using fenestrated and branched endografts was associated with a 1% risk of mortality at 30 days, which compares to a mortality of 21% in a recent study of over 14,000 patients treated by open surgical repair in the United States.
- “When we began the study, we had no idea the rate of mortality would be so much lower than the historical results of open surgical repair,” Oderich said.
- Spinal cord injury affected 6% of patients enrolled in the FB-EVAR study, which is similar to contemporary open surgical studies in which the rate of spinal cord injuries reported was 5% to 10%.
