This study states that An analysis was conducted of early and midterm outcomes of a large series of patients treated with in situ laser fenestration (ISLF) during thoracic endovascular aortic repair (TEVAR) of acute and subacute complex aortic arch diseases, such as Stanford type A aortic dissection (TAAD), type B aortic dissection (TBAD) requiring proximal sealing at zone 2 or more proximal, thoracic aortic aneurysm or pseudoaneurysm, and penetrating aortic ulcer. We present the perioperative and follow-up outcomes and discuss the rate of complications. This is a retrospective review of prospectively collected data from January 2017 to March 2019 of patients treated with TEVAR and ISLF of aortic arch branches at a large tertiary academic institution in an urban city in China. Preoperative, intraoperative, and follow-up clinical and radiographic data are analyzed and discussed. A total of 148 patients presented with symptomatic and acute or subacute TAAD, TBAD, thoracic aortic aneurysm, or penetrating aortic ulcer for a total of 183 arch vessels. There were 105 men and 43 women, 21 to 79 years of age (mean, 54.9 ± 12.9 years). Time from symptom onset to time of surgery was an average of 7 ± 3 days. Survivor follow-up duration ranged from 5 to 24 months (mean, 15 ± 5 months).
