完全性肺静脉异位引流术后肺静脉狭窄手术干预9例近中期结果

Surgery for pulmonary venous stenosis after total anomalous pulmonary venous connection repair: Midterm results of 9 patients

目的总结阜外医院过去10年完全性肺静脉异位引流(TAPVC)术后肺静脉狭窄(PVS)患者行再次手术干预的近中期结果。方法纳入2009~2019年于阜外医院完成手术治疗的9例TAPVC术后PVS患者,其中男4例、女5例,手术时年龄(5.10±5.00)岁。根据肺静脉成形手术方式将患者分为2组:无缝线缝合(sutureless)组(n=3)和非无缝线缝合(non-sutureless)组(n=6)。分析患者的临床资料。结果本组患者原发TAPVC类型包括:心上型4例,心内型2例,心下型1例,混合型2例。全组患者中位体外循环时间95(63,208)min,中位主动脉阻断时间58(30,110)min,术后中位ICU滞留时间24(24,2 136)h。早期院内死亡1例(11.1%)。1例(11.1%)合并单心室患者发生住院并发症,术后行血液滤过治疗。随访时间11.9(2.2,18.0)个月,随访期间死亡2例,死因分别为肺静脉再狭窄及脑卒中。Sutureless组与non-sutureless组术后结果及随访结果差异无统计学意义(P>0.05)。结论外科手术是TAPVC术后出现PVS的有效治疗手段,但仍存在较高的并发症发生率及死亡率,sutureless缝合技术在此类患者中应用的优势仍有待验证。

Objective To review our experience of reoperations for pulmonary venous stenosis(PVS) after total anomalous pulmonary venous connection(TAPVC) repair for the past decade in Fuwai Hospital. Methods Nine patients underwent reoperation for PVS between 2009 and 2019 in Fuwai Hospital, including 4 males and 5 females with an average age of 5.10±5.00 years. The patients were divided into a sutureless group(n=3) and a non-sutureless group(n=6). Clinical data were reviewed and analyzed. Results For primary TAPVC type, 4 patients were supracardiac, 2 patients were cardiac, 1 patient was infracardiac, and 2 patients were mixed-type anomaly. The median cardiopulmonary bypass time was 95(63, 208) min, aortic clamping time was 58(30, 110) min, ICU stay was 24(24, 2 136) h. Early hospital death occured in 1(11.1%) patient. One(11.1%) patient with single ventricle physiology had hospital comorbidity, who underwent hemofitration therapy. The follow-up time was 11.9(2.2, 18.0) months, during which 1 patient died of restenosis of pulmonary vein and another patient died of stroke. No statistically significant difference was found between the sutureless group and non-sutureless group in postoperative or follow-up results(P>0.05). Conclusion Surgery is effective for treatment of PVS after repair of TAPVC, yet with a realatively high morbidity and mortality. The advantage of sutureless repair over conventional repair for this particular group of patients is yet to be verified.
