Application of Hybrid Procedures for Thoracoabdominal Aortic Aneurysm

Different surgical procedures for Stanford type A aortic dissection: A case control study

Objective To analyze the near-term clinical efficacy of two different surgical procedures (Sun's procedure and Debranching combined endovascular stent-graft procedure) to cure Stanford type A aortic dissection, and summarize the clinical experience to help better master the indications of the two surgical procedures. Methods We retrospectively analyzed the clinical data of 46 patients with Stanford A aortic dissection in our hospital between September 2014 and September 2017. There were 39 males and 7 females at age of 20–74 (48.67±11.80) years. According to different surgical methods, the patients were divided into a Sun's procedure group (26 patients) and a debranching combined endovascular stent-graft procedure group (20 patients). The clinical effect of the two groups was compared. Results The debranching combined endovascular stent-graft procedure group was significantly superior to the Sun's group in cardiopulmonary bypass (CPB) time, aortic cross clamp(ACC) time, intraoperative urine output, postoperative mechanical ventilation time, postoperative 24 h volumes of drain, CICU time, renal function recovery of postoperative 72 h and total hospital stay(P<0.05). The incidence of transient neurological damage after operation in the debranching combined endovascular stent-graft procedure group was significantly lower than that of the Sun's procedure group(P<0.05). The follow-up time ranged from 3 to 36 months. And the follow-up rate was 90.5%. One patient in the Sun's procedure group died of serious pulmonary infection postoperative 30 days. One patient in the debranching combined endovascular stent-graft group was found to have internal leakage in the early postoperative examination and disappeared after 6 months. Sun's procedure group did not find endoleak. All patients during the follow-up time did not appear brain, coagulation disorders, stroke, paraplegia, upper limb ischemia and other complications. Conclusion For Stanford type A aortic dissection, debranching combined surgery may have the risk of postoperative endoleak, but the overall effect is superior to Sun's operation. Therefore, debranching combined surgery should be preferred for the treatment of this type of dissection.

分期杂交手术治疗胸腹主动脉夹层

目的总结腹主动脉去分支化手术联合主动脉腔内隔绝术治疗胸腹主动脉夹层的经验。方法自 2018 年 1 月至 2019 年 6 月，南京鼓楼医院采用腹主动脉去分支化手术联合主动脉腔内隔绝术治疗胸腹主动脉夹层 12 例，男 10 例、女 2 例，年龄 36～63（50±9）岁。结果随访 6～24 个月，全组无死亡，1 例术后左下肢单瘫，1 例出现肾功能不全。随访期间 1 例患者术后 1 个月出现主动脉支架近端逆撕，行全主动脉弓置换术后痊愈。2 例患者出现腹腔干动脉近端内漏，予以弹簧圈栓塞后痊愈，其余患者 CT 血管造影（CTA）检查未见吻合口造影剂渗漏及人工血管扭曲、闭塞。结论腹主动脉去分支化手术联合主动脉腔内隔绝术治疗胸腹主动脉夹层可取得良好近期疗效，中远期疗效仍有待进一步观察随访。
