摘要目的:评价杂交技术在急性Standford A型主动脉夹层应用中的有效性。方法:回顾性分析2016年1月至2018年12月因急性Standford A型主动脉夹层于阜外医院行全主动脉弓替换手术的患者。共入选患者504例，男383例，女121例；年龄(50.0±11.7)岁。高血压患病率为79.6%，平均发病至手术时间(69.5±40.0)h。其中110例接受了一期Ⅱ型杂交全主动脉弓修复术，394例接受了传统全主动脉弓置换及支架象鼻置入手术。采取倾向性评分方法对两组患者资料进行匹配，对两组患者间的术前基线资料、术中及术后结果进行分析比较。结果:504例患者，男性患者占75.9%，早期死亡24例(4.8%)，术后脑梗塞20例(4.0%)，截瘫7例(1.4%)。杂交手术组患者年龄[(62.1±6.8)岁对(46.6±10.4)岁， P<0.001]、高血压(87.3%对77.4%， P＝0.033)、冠心病(13.6%对6.1%， P＝0.016)及慢性阻塞性肺疾病(12.7%对3.6%， P＝0.001)均高于开放手术组。杂交组患者在体外循环时间[(143.7±53.7)min对(175.3±52.7)min， P<0.001)]及主动脉阻断时间[(78.5±33.6)min对(106.9±37.8)min， P<0.001)]均明显低于开放手术组。两组患者院内死亡、再手术及术后生存比例差异均无统计学意义。随访2～43个月[(22.6±11.1)个月]，杂交手术组5例患者随访死亡(4.9%)，开放手术组10例患者随访死亡(2.7%)。杂交组再干预患者3例(3.1%)，开放组再干预11例(3.3%)。3例失访，患者未进行门诊复查，亦未能完成电话随访。 结论:杂交全主动脉弓修复术治疗急性Standford A型主动脉夹层早中期效果满意，其与传统开放手术的预后比较仍需要长期随访观察。

abstractsObjective:By analyzing the early- and mid-term clinical results of type Ⅱ hybrid aortic arch repair(HAAR) for the treatment of acute type A aortic dissection(ATAAD), the efficacy of hybridization technique in the application of acute type A aortic dissection was evaluated systematically.Methods:We retrospectively studied the records of patients with ATAAD who were admitted to the Beijing Fuwai Hospital between January 2016 and December 2018. 504 patients were included for analysis , 383 men and 121 women, mean age(50.0±11.7) years, the rate of hypertension was 79.6%, the average time of onset to operation was(69.5±40.0) hours. During this period, 110 continuous patients underwent hybrid aortic arch repair(HAAR) without deep hypothermic circulatory arrest, the landing zone of stent was located in ascending aorta(zone 0); 394 consecutive patients with ATAAD involving the aortic arch received traditional total aortic arch replacement with frozen elephant trunk(FET). A propensity score-matching analysis was applied to adjust for age and gender.The preoperative, perioperative and postoperative data in the HAAR group and FET group were compared.Results:For all 504 patients , male patients accounted for 75.9%. There were 24 cases of early death(4.8%), 20 cases of stroke(4.0%) and 7 cases of paralysis(1.4%). HAAR group showed more age[(62.1±6.8) years vs (46.6±10.4) years, P<0.001)], hypertension(87.3% vs 77.4%, P=0.033), coronary artery disease(13.6% vs 6.1%, P=0.016) and chronic obstructive pulmonary diseases(12.7% vs 3.6%, P=0.001) than the FET group. HAAR group showed shorter cardiopulmonary bypass time[(143.7±53.7) min vs (175.3±52.7) min, P<0.001] and aortic cross-clamping time[(78.5±33.6) min vs (106.9±37.8) min, P<0.001] than the FET group. Between the two groups there was no significant difference in operative mortality, rate of reoperation, and late mortality. Follow-up period ranged from 2 to 43 months, averaged(22.6±11.1) months. During folloe-up period , there were 5 cases of death(4.9%) and 3 cases of reoperation(3.1%) in HAAR group, 10 cases of death(2.7%) and 11 cases of reoperation(3.3%) in FET group. 3 patients lost follow-up because of not been rechecked in the outpatient department or the phone was not connected. Conclusion:This single -stage hybrid arch procedure offers an alternative approach to acute type A dissection and associated with acceptable early and midterm major morbidity and mortality in old-age patients. Future further researches are required to confirm the long-term outcomes.
