目的比较深低温停循环下全弓置换加支架象鼻术与复合全主动脉弓置换术治疗A型主动脉夹层的手术效果及早期随访结果。方法2012年1月至2014年4月行深低温停循环下全主动脉弓置换加支架象鼻手术17例(深停组),同期行复合全主动脉弓置换术治疗A型主动脉夹层19例(复合组),比较2组术中体外循环结果,术后并发症,术后30d死亡率等指标。结果2组均成功完成手术,手术死亡率均为0%,深停组和复合组体外循环时间:(173±24)min和(136±28)min(P〈0.05),阻断时间:(101±12)min和(77±11)(P〈0.05),术后机械通气时间:(19±3)h和(11±3)h(P〈0.05),ICU停留时间:(3.0±0.6)d和(1.7±0.8)d(P〈0.05),截瘫:5.8%(1/17)和0%(P〈0.05),肾衰竭:11.8%(2/17)和0%(P〈0.05),脑梗死均为O%,术后30d死亡率:23.5%(4/17)和10.5%(2/19)(P〉0.05)。共随访33例,随诊率89%,随访期间2组均未发生死亡、脑梗死、肾衰竭等并发症。结论复合组较手术创伤和并发症发生明显减少,可提高术后生存率。
Objective To compare arch hybrid debranching procedure and open arch replacement on type A dissection. Method From Jan 2012 to Apr 2014, 19 type A dissection cases received arch hybrid debranching procedure, and 17 cases did open total arch replacement. Results Operations were successfull in all patients. The operation time were (5.86 ±1.14) h vs. (5. 13 ± 0. 98 ) h ( P 〉 0. 05 ), bleeding amount 24hs post operation were (410 ± 170) ml vs. ( 360 ± 210 ) m] ( P 〉 0. 05 ) , intraoperative bleeding was ( 1 080 ± 190 ) ml vs. ( 950 ± 170 ) ml ( P 〉 O. 05 ) , extracorporeal circulation : ( 173 ±24 ) minvs. (136 ±28) min(P〈0.05), block time was (101± 12) vs. (77± 11) min(P 〈0.05), mechanical breath time post operation was ( 19 ± 3 ) h vs. ( 11 ± 3 ) h( P 〈 0.05 ), ICU stay time was ( 3.0 ± 0.6)dvs. (1.7±0.8)d(P〈0.05), paraplegia incidence was 5.8% (1/17) vs. 0%(P〈0.05), renal failure occurred in 11.8% (2/17) vs. 0% (P 〈 0. 05). Perioperative mortality was 23.5% (4/17) vs. 10.5%(2/19) (P 〉 0.05). 33 cases were followed up for 1 - 28 months. There were no severe complications occurred including death, cerebral infarction, renal failure. Conclusion Hybrid debranching procedure significantly reduces operational trauma and complications and improves survival rate in patients of type A dissection.
