ABSTRACT

Objective:

To summarize the early and intermediate outcomes of second-grade false-lumen endovascular occlusive repair (FLEVOR) for aortic dissection.

Methods:

The clinical data of 12 patients undergoing second-grade FLEVOR after proximal repair of aortic dissection at our center from Aug 2016 to Aug 2019 was retrospectively analyzed.

Results:

The mean age was (51.3±14.9) years old. Four patients received open repair due to Stanford type A aortic dissection previously, the other 8 patients underwent thoracic endovascular aortic repair for Stanford type B aortic dissection. The time to the proximal repair varied from 3 months to 16 years. The technical success rate was 100%. Visceral ischemia, early spinal cord ischemia and in-hospital death did not occur perioperatively. The mean follow-up time was 16.7 months. Persistent false lumen perfusion was found in 3 patients, complete thrombosis of false lumen was achieved in the other 8 patients. The maximum diameter of abdominal aorta decreased in 8 (72.7%) patients.

Conclusions:

FLEVOR could block the blood flow from the false lumen and induce the thrombosis of false lumen, which promotes the aortic remodeling. Meanwhile, FLEVOR could protect the blood supply of spinal cord and viscera, and reduce the risk of type Ⅱ endoleaks.
