摘  要:目的越来越多的&Jg复杂先天性心脏病需要应用牛颈静脉带瓣外管道来重建右心室流出道,本研究希望通过回顾性随访研究来评估牛颈静脉带瓣外管道的中远期功能。方法回顾性分析2002年1月至2013年12月期间接受牛颈静脉带瓣外管道重建右心室流出道手术患儿53例。其中男33例,女20例;手术年龄1~142个月,中位数36个月;体重3.2~35.0kg,平均(14.4±8.5)kg;术前SpO2为74%~99%,平均(85.1±6.5)%。术前诊断为肺动脉闭锁伴室间隔缺损33例,法洛四联症1例,主动脉瓣病变(狭窄或者反流)8例,完全性大动脉转位伴肺动脉狭窄7例,动脉单干4例。结果早期死亡2例,无晚期死亡。51例患儿得到了全面随访,其中15例出现牛颈静脉带瓣外管道的衰败,衰败率为29.4%,包括:外管道重度狭窄10例,狭窄伴反流3例,单纯反流2例。术后1、3、5、7年牛颈静脉带瓣外管道免于衰败率分别为98.0%(50/51)、85.8%(44/51)、76.8%(40/51)和62.1%(36/51),其中9例发生了感染性心内膜炎。未发生感染性心内膜炎患儿中,术后2、5、7年带瓣外管道免于衰败率分别为97.5%(41/42)、81.2%(35/42)和69.6%(33/42);发生感染性心内膜炎患儿中,术后2、5、7年带瓣外管道免于衰败率分别为66.7%(6/9)、55.6%(5/9)和33.3%(3/9)。多因素分析显示感染性心内膜炎是外管道衰败的独立危险因素(OR6.735,95%CI 1.348~33.647)。结论带瓣外管道的需求量越来越大,与国内来源的缺乏形成了严重的矛盾,中远期随访发现牛颈静脉带瓣外管道存在相对较高的衰败率,感染性心内膜炎是外管道衰败唯一的独立危险因素。Objective To assess the condition of bovine jugular vein (BJV) after medium to long-term follow-ups. Methods A total of 53 patients were implanted with BJV conduits from January 2002 to December 2013. There were 33 boys and 20 girls with a mean age of 36 (1-142) months, a mean weight of (14. 4± 8. 5) (3.2-35. 0) kg and a mean preoperative SpO2 of (85.1± 6. 5)%(74%- 99%). There were pulmonary atresia (PA) plus ventricular septal defect (VSD) (n = 33), tetralogy of Fallot (TOF, n = 1 ), aortic valve malformation (aortic valve stenosis or regurgitation or both) (n = 8), complete transposition of the great artery (TGA) & pulmonary stenosis (PS) (n = 7) and persistant truncus arteriosus (PTA) (n = 4). Results There were 2 cases of early mortality while no late mortality was reported. Follow-ups were conducted for 51 cases. The failure of BJV conduits was due to severe stenosis (n = 10), stenosis plus regurgitation (n = 3) and regurgitation alone (n = 2). The failure rate was 29. 4%. Freedom from BJV conduits failure at 1, 3, 5 and 7 years was 98. 0%, 85. 8%, 76. 8% and 62. 1%. There were 9 cases of endocarditis. Freedom from BJV conduits failure at 2, 5 and 7 years was 66.7%, 55.6% and 33.3% in cases of endocarditis versus 97. 5 %, 81.2 % and 69.6% in those without endocarditis. Multivariate logistic regression analysis implicated endocarditis as a significant risk factor associated with BJV conduit failure (OR 6. 735, 95% CI 1. 348- 33. 647). Conclusions A great contradiction exists between higher demands for valvular conduits and insufficient supplies in China. BJV conduits have a relatively high failure rate. Endocarditis is a significant risk factor associated with failed BJV conduits.
