摘 要:目的总结分析右室双出口(DORV)的手术方案、术后并发症及死亡率,以提高该类患儿手术存活率及改善其生活质量。方法2009年1月至2015年7月接受手术治疗的66例法洛四联症型右室双出口患儿。合并主动脉瓣下/双关型室间隔缺损(VSD)51例,无关VSD型15例,合并完全性房室间隔缺损9例,合并冠状动脉异常2例,合并镜面右位心2例。手术年龄6个月至14岁,平均(4.18±3.19)岁。体重6.5—44(14.98±8.13)kg。其中,根治手术55例,BT分流5例,Glenn分流4例,Fontan术2例,全组再手术3例。结果本组病例中近期死亡7例,死亡率为10.6%,根治手术死亡率为9.1%。全组呼吸机使用时间(54.94±70.07)h,ICU停留时间为(5.23±5.65)d。按照右室流出道(RVOT)压力阶差将49例存活的DORV根治术患者分为≤25mmHg,25-40mmHg及〉40mmHg三组,比较三组间插管时间、ICU停留时间及住院时间,≤25mmHg组与25—40mmHg组之间差异无统计学意义(P〉0.05),而≤25mmHg组与〉40mmHg组比较其插管时间及ICU住院时间明显缩短(P〈0.01),死亡原因主要为:低心排综合征,瓣膜反流,Ⅲ度房室传导阻滞,冠脉异常起源。结论符合根治手术条件的法洛四联症型DORV可以取得良好的一期根治手术结果。完全性房室间隔缺损(CAVSD)可增加该类患儿手术的死亡率。术后瓣膜反流、重度左右室流出道梗阻为该类患儿主要死亡原因。Objective To summarize the early surgical result of the double outlet right ventricle (DORV) with obstruction of right ventricular outlet (RVOTO). Methods From January 2009 to July 2015, 66 cases of DORV with RVOTO received the surgical treatment, including 55 cases of biventricular repair, 5 cases of Blalock-Tanssing (BT) shunt, 2 cases of Glenn shunts, and 4 cases of Fontan procedure. Results The Total mortality rate was 10. 6% and 9. 1%, and patients were died after the biventricular re- pair. The average duration of ventilation was ( 54. 94±70.07 ) h, and the average residence time of inten- sive care unit (ICU) was (5.23 ± 5.65 ) d. According to the RVOT pressure, 49 survival patients receiving biventricle repair were divided into three groups. The ventilation and ICU stay time was much longer in the 〉40 mmHg group ( P 〈0.01). The main causes of death were low heart row syndrome, valvular regurgi- tation, third degree conduction block, and coronary anomalous origin. Conclusions Biventricular repair of the DORV with RVOTO can achieve good results. The complete atrioventricular septal defects (CAVSD) may increase the mortality of the patients with this kind of operation for a severe left ventricular outflow tract obstruction.
