目的 比较破裂性腹主动脉瘤行腔内修复术(EVAR)与开放手术围手术期的疗效.方法 回顾性分析2006年1月至2013年1月解放军总医院血管外科符合纳入和排除标准接受手术治疗的66例破裂性腹主动脉瘤患者的临床资料,根据手术方式分为EVAR组(40例)和开放手术组(26例).EVAR组男性30例,女性10例;年龄47 ~ 78岁,平均年龄(71±7)岁.开放手术组男性21例,女性5例;年龄45 ~ 87岁,平均年龄(72±9)岁.采用x2检验和t检验比较2组患者围手术期手术时间、术中输血量、ICU时间、病死率、不良事件发生率及二次干预率的差异.结果 EVAR组手术时间、术中输注悬浮红细胞数量、ICU时间、病死率及不良事件发生率均低于开放手术组,组间差异均有统计学意义[(182 ±44) min比(384±108) min,t=-10.59,P=0.00;(0.4±0.8)单位比(1.1±1.8)单位,t=-2.19,P=0.03;(3.0±1.8)d比(8.5±5.1)d,t=-6.34,P=0.00;20.0% (8/40)比46.2% (12/26),x2 =5.10,P =0.02;25.0% (10/40)比53.8% (14/26),x2=5.67,P =0.02].2组术中输注冰冻血浆数量、二次干预率差异无统计学意义(分别为t=-1.98,P=0.05;x2=0.49,P=0.48).结论 EVAR较开放手术可降低破裂性腹主动脉瘤围手术期病死率和不良事件发生率,但中远期疗效尚需进一步研究.%Objective To compare the perioperative outcome between the endovascular repair (EVAR) and open surgical repair (OSR) for ruptured abdominal aortic aneurysm.Methods From January 2006 to January 2013,totally 66 patients with ruptured abdominal aortic aneurysm (rAAA) treated by surgery were retrospectively analyzed in Department of vascular surgery,People's Liberation Army General Hospital.According to the repair method,all the subjects were divided into EVAR group and OSR group.EVAR group included 40 patients,30 patients were male,10 patients were female,aged from 47 to 78 with a mean of (71 ±7) years.OSR group included 26 patients,21 patients were male,aged from 45 to 87 with a mean of (72 ± 9) years.The difference of the operation time,the amount of suspended red blood cells,ICU stay time,case fatality rate,adverse event rate and the difference of the two intervention rate were compared between the 2 groups by x2 test and t test.Results There were significant differences between the 2 groups in operation time,the amount of suspended red blood cells,ICU stay time,case fatality rate,adverse event rate ((183 ±44) minutes vs.(384 ± 108) minutes,t =-10.59,P =0.00;(0.4 ±0.8)units vs.(1.1±1.8) units,t=-2.19,P=0.03;(3.0±1.8) dvs.(8.5±5.1) d,t=-6.34,P=0.00;20.0% (8/40) vs.46.2% (12/26),x2 =5.10,P =0.02;25.0% (10/40) vs.53.8% (14/26),x2 =5.67,P =0.02).There were no significant differences in frozen plasma quantities and the two intervention rate between the 2 groups (t =-1.98,P =0.05;x2 =0.49,P =0.48).Conclusions EVAR decreases the perioperative mortality and adverse event of rAAA compared with OSR.More studies are necessary to compare the middle and long-outcome between EVAR and OSR of rAAA.
