Abstract
Objective: The purpose of this study is to evaluate the result of thoracic endovascular aortic repair for retrograde type A acute aortic dissection and complicated type B acute aortic dissection. Methods: Retrospective study was performed on 20 patients who underwent thoracic endovascular aortic repair for acute aortic dissection. Result: Mean age was 64.9±11.6 years old. Sixteen patients of all were male. Three cases were retrograde Stanford type A and 17 cases were Stanford type B. The number of complicated type B dissection was 8 cases, which included 4 with branch ischemia, 3 with rupture and 1 with lower extremity ischemia. Mean interval from the onset to the operation was 13.9±25.0 days. Type of device was 1 with TAG, 15 with Conformable TAG, 3 with RELAY Plus, and 1 with Najuta. Extra-anatomical bypass of neck vessels was added to 4 cases. Device success rate was 100%. There was no death after the operation and perioperative complications included one paraparesis and one cerebral infarction. The entry closure and thrombus on target area was obtained in all cases with no device-associated complications, such as endoleak and re-enlargement. Post-operative computed tomography demonstrated that true lumen dilated and false lumen diminished in early and mid-term. Conclusion: Thoracic endovascular aortic repair for acute aortic dissection was performed effectively and safely.
