单心室合并完全性肺静脉异位引流的外科治疗

Surgical Treatment of Single Ventricle With Total Anomalous Pulmonary Venous Connection in Relevant Patients

目的:总结单心室合并完全性肺静脉异位引流(TAPVC)的外科治疗效果。方法:入选2008-09至2016-03期间,我院手术治疗的单心室合并TAPVC患儿25例,年龄5天~14岁,体重3.3~49.5kg,心上型TAPVC 22例,心下型TAPVC 1例,混合型TAPVC 2例;合并完全性房室间隔缺损17例,三尖瓣闭锁2例,二尖瓣闭锁2例;中度以上房室瓣反流4例,肺动脉闭锁5例,肺静脉梗阻9例。结果:院内早期死亡5例,死亡率20%(5/25),死亡原因均为低心排血量综合征。存活20例患儿随访1~65个月,7例再次手术,其中5例完成二期改良Fontan术,1例因重度房室瓣反流行房室瓣置换术,另1例因肺静脉梗阻及重度房室瓣反流行肺静脉狭窄矫治+房室瓣成形术;余13例患儿未再次手术。20例出院患者随访期间3例死亡,死亡原因分别为低心排血量综合征、蛋白丢失性肠病和神经系统损伤。余存活患儿一般情况好,未发现残余肺静脉梗阻。结论:单心室合并TAPVC常合并右心房异构,心内畸形复杂,手术治疗仍具有较高死亡率。

Objective： To summarize surgical result of single ventricle with total anomalous pulmonary venous connection （TAPVC） in relevant patients. Methods： A total of 25 patients of single ventricle with TAPVC treated in our hospital from 2008-09 to 2016-03 were summarized. The patients were between 5 days to 14 years of age with body weight at （3.3-49.5） kg. There were 22 patients with supracardiac type TAPVC, 1 with infracardiac type TAPVC and 2 with mixed type TAPVC; in addition,17 cases having complete atrio-ventricular canal defect, 2 having tricuspid atresia, 4 having more than moderate atrio-ventricular valve regurgitation, 5 having pulmonary atresia and 9having pulmonary venous obstruction. Results： There were 5/25 （20%） patients died at the early stage for low cardiac output syndrome. Followed-up study was conducted in 20 survivals for （1-65） months and 7 patients had re-surgery including 5 with modified Fontan operation, 1 with atrio-ventricular valve replacement due to severe atrio-ventricular valve regurgitation, 1 with pulmonary venous stenosis repair ＋ atrio-ventricular valve replacement due to pulmonary venousobstruction and severe atrio-ventricular valve regurgitation. 3 patients died during followed-up period because of low cardiac output syndrome, protein lost intestine disease and neurological injury respectively. The rest survivals had good general condition, no residualpulmonary venous obstruction was found. Conclusion： The patients of single ventricle with TAPVC were frequently associated with right atrial isomerism and complex cardiac anomaly; surgical treatment still having the high mortality.
