Abstract

Objectives: A primary goal of thoracic endovascular aortic repair (TEVAR) for type B acute aortic dissection (BAAD) is exclusion of the primary entry tear with a suitable stent graft (SG) to reestablish true lumen flow and promote aortic remodeling. This study aimed to determine the safety and efficacy of a conformable thoracic SG in a Japanese population with complicated BAAD.

Methods: Between 2016 and 2017, 43 patients with complicated BAAD were enrolled in this prospective, nonrandomized, multicenter post-market surveillance study at 27 sites in Japan. All patients underwent TEVAR using the Gore TAG Conformable Thoracic Endoprosthesis (CTAG) (W.L. Gore and Associates, Flagstaff, AZ).

Results: The most common TEVAR indication for complicated BAAD was malperfusion (41.9%; 24 out of 43) and aortic rupture was observed in 32.5% of patients (14 out of 43). All SG implants were successfully completed and there was no patient with surgical conversion. Thirty-day mortality was 7.0% (3 out of 43) and one patient (2.3%) experienced spinal cord ischemia during hospitalization. Entry tear exclusion was achieved in 91.3% of patients at 1 month, and 95.7% at 24 months. Through 24 months after TEVAR, no retrograde type A aortic dissection was observed and distal stent graft induced new entry was observed in two patients (4.7%).

Conclusion: TEVAR utilizing the CTAG device for complicated BAAD in Japan demonstrated a low incidence of perioperative mortality and complications. Complications directly attributed to the SG including RTAD and dSINE were uncommon and the midterm outcomes were deemed satisfactory.

来自日本一项多中心上市后监测研究的复杂B型急性主动脉夹层的胸血管内主动脉修复结果
目的:B型急性主动脉夹层(BAAD)的胸腔血管内主动脉修复(TEVAR)的主要目的是通过合适的支架移植(SG)来排除原发性入口撕裂,以重建真正的管腔流动并促进主动脉重塑。本研究旨在确定适形胸椎SG在日本复杂BAAD患者中的安全性和有效性。方法:在2016年至2017年期间,在日本27个地点招募了43名合并BAAD的患者参与这项前瞻性、非随机、多中心的上市后监测研究。所有患者均使用Gore TAG适形胸内假体(CTAG) (W.L. Gore and Associates, Flagstaff, AZ)进行TEVAR。结果:复杂BAAD最常见的TEVAR指征是灌注不良(41.9%;43例患者中有24例出现主动脉破裂,32.5%的患者(43例中有14例)出现主动脉破裂。所有SG植入物均成功完成,没有患者进行手术转换。30天死亡率为7.0%(3 / 43),1例(2.3%)患者在住院期间出现脊髓缺血。91.3%的患者在1个月时达到了进入性撕裂排除,而在24个月时达到了95.7%。TEVAR术后24个月,未观察到逆行性A型主动脉夹层,2例(4.7%)患者观察到远端支架移植诱导的新进入。结论:日本采用CTAG装置的TEVAR治疗复杂的BAAD,围手术期死亡率和并发症发生率低。直接由SG引起的并发症包括RTAD和dsin并不常见,中期结果令人满意。
