摘要
目的：探讨婴幼儿肺血减少型复杂先心病的肺循环血流来源.方法：回顾性分析96例年龄4～36（22.2±9.36）个月肺血减少型复杂先心病患儿的临床资料.根据肺循环的血流来源,分为单纯肺动脉供血（A型）、单纯体动脉供血（B型）和肺动脉、体动脉双重供血（C型）3种类型.结果：96例中A型56例,B型25例,C型15例.33.33%（32/96）合并单纯PDA,存在于TOF、PA-IVS、PA-VSD、DORV、SV、TGA和ccTGA中;7.29%（7/96）合并单纯体-肺侧支形成,存在于TOF、PA-IVS、PA-VSD和DORV中;1.04%（1/96）同时合并动脉导管未闭和体-肺侧支,诊断为PA-VSD.结论：婴幼儿肺血减少型复杂CHD中,多数病种同时合并PDA,体-肺动脉侧支通常在PA-VSD、TOF和DORV中有较高的发生率,在其它病种中较少见.
Objective： To analyze pulmonary blood supply in complex congenital heart defect（CHD） with diminished pulmonary blood flow in infant. Methods： There were 96 cases with complex CHD with diminished pulmonary blood flow, aged 4～36（22.24±9.36） months. The classification standard was according to the source of pulmonary blood flow. Type A, pulmonary arterial blood flow was only from ventricle. Type B, the pulmonary blood flow was from patent ductus arteriosus （PDA） and/or aortopulmonary collateral arteries （APCAs）. Type C, the lung accepted both pulmonary arterial blood flow and systemic arterial blood flow. Results： There were 56 cases in type A, 25 cases in type B, 15 cases in type C. The incidence of PDA which consisted in TOF、PA - IVS、PA - VSD、DORV、SV、TGA and ccTGA was 33.33 %. The incidence of APCAs which consisted in TOF、PA - IVS、PA - VSD and DORV was 7.29%. PDA and APCAs were concomitant in one patient whom diagnosis was PA - VSD that the incidence was 1.04%. Conclusion： Most kinds of diseases can accompany PDA in complex CHD with diminished pulmonary blood flow in infant. The incidence of aortopulmonary collateral arteries is higher in PA - VSD, TOF and DORV, which is less common in other such diseases.
