Abstract

Objective: To summarize the experience of arterial duct (AD) stenting in children with ductus-dependent hypoplastic right heart syndrome (HRHS). Methods: Seven children including 4 cases of pulmonary atresia with intact ventricular septum (PA-IVS) with HRHS and 3 cases of critical pulmonary stenosis (CPS)-IVS with HRHS underwent AD stenting in Qingdao Women and Children's Hospital between January 2012 and January 2019. During the same period, 9 patients of PA-IVS with HRHS received Blalock Taussig (B-T) shunt. Two groups of children on the operation time, hospital stay time, intensive care time and mortality were compared.T test or Mann-Whitney U test was used for comparison between the two groups. Results: There was no significant difference in the age (18 (7-100) vs. 17 (1-142) d, U=31.000, P>0.05) and weight ((3.8±1.1) vs. (3.7±1.3) kg, t=0.272, P>0.05) between the AD stenting group and the B-T group.The operation time ((108±7) vs. (160±49) min, t=-4.304), intensive care time ((3.4±1.0) vs. (6.3±4.5) d, t=-8.692) and total hospitalization time ((10.3±1.0) vs. (26.3±1.0) d, t=-7.822) in the AD stenting group were differed significantly compared with the B-T group (all P<0.05). The transcutaneous oxygen saturation improved significantly (0.723±0.125 vs. 0.926±0.005, t=-6.044, P<0.05) after AD stenting. The diameter of AD stent ranged from 3.5 to 4.0 mm, and the length of AD stent was 16-21 mm. There were no complications such as vascular injury, acute thrombus, catheter spasm and death in the AD stenting group. The mortality of children in the B-T group was 3 in 9 cases. Three cases in the AD stenting group received pulmonary valvulotomy and bilateral Glenn operation at 6, 9 and 9 months after AD stenting, respectively. Conclusions: AD stenting is a feasible, effective, safe and minimally invasive procedure for children with ductus-dependent HRHS. It can even be used as an alternative to B-T shunt.

目的: 总结动脉导管支架置入术在动脉导管依赖性右心发育不良综合征(HRHS)患儿中的应用经验。 方法: 回顾性研究2012年1月至2019年1月在青岛市妇女儿童医院行动脉导管支架置入术的7例患儿的临床资料,其中4例为室间隔完整的肺动脉闭锁(PA-IVS)伴HRHS,3例为室间隔完整的危重肺动脉瓣狭窄伴HRHS。以同医院同期行外科Blalock-Taussig(B-T)分流术的9例PA-IVS伴HRHS患儿作为对照,比较两组患儿手术时间、住院时间、重症监护时间、病死率等临床资料。组间比较采用t检验及Mann-Whitney U检验。 结果: 动脉导管支架置入术患儿年龄和体重与B-T分流组相比差异无统计学意义[18(7~100)]比17(1~142)日龄,U=31.000,P>0.05;(3.8±1.1)比(3.7±1.3)kg,t=0.272,P>0.05]。动脉导管支架组手术时间[(108±7)比(160±49)min]、重症监护时间[(3.4±1.0)比(6.3±4.5)d]、总住院时间[(10.3±1.0)比(26.3±1.0)d]均明显低于B-T分流组,差异有统计学意义(t=-4.304、-8.692、-7.822,P均<0.05)。动脉导管支架置入后经皮血氧饱和度较术前明显改善(0.723±0.125比0.926±0.005,t=-6.044,P<0.05)。动脉导管支架直径为3.5~4.0 mm,支架长度为16~21 mm。动脉导管支架组患儿无血管损伤、急性血栓、导管痉挛及死亡,随访期间无支架移位、狭窄发生。9例B-T分流组患儿围术期死亡3例。动脉导管支架组3例肺动脉闭锁患儿分别在术后6、9、9个月时行肺动脉瓣切开术及双向Glenn手术。 结论: 对于动脉导管依赖性HRHS患儿,动脉导管支架置入术是一种可行、有效、安全、微创的手术方法,可作为早期外科B-T分流术的替代方法。.
