一侧肺动脉缺如合并先天性心脏病的介入治疗分析

目的:总结经导管介入治疗一侧肺动脉缺如合并先天性心脏病的疗效。方法:我科自2005年1月至2009年4月诊断5例一侧肺动脉缺如合并先天性心脏畸形,其中合并动脉导管未闭4例,合并房间隔缺损1例;左肺动脉缺如1例,右肺动脉缺如4例;本组男性1例,女性4例,年龄1.5～11岁,3例肺部反复感染、1例咯血及1例发绀。均通过临床体检、X线胸片、心电图、经胸超声心动图检查及多排CT或造影确诊。结果:4例合并动脉导管通过介入治疗成功封堵。术后平均3d出院,未出现并发症,随诊3个月～4年心脏均恢复正常大小。1例肺动脉高压为极重度,合并房间隔缺损,出现发绀,不能除外原发肺动脉高压因素,放弃介入治疗,予口服扩血管药物治疗,出院随诊。结论:一侧肺动脉缺如合并先天性心脏病临床常表现为中、重度肺动脉高压多伴一侧肺发育不良,手术风险大。应用介入治疗显示出创伤小、并发症少,恢复快等优势,挽救了一些外科也难以处理的高风险重症患儿。

The interventional procedure in the unilateral absence of a pulmonary artery combined congenital heart diseases

Objective:This study was to evaluate the safety and efficacy of transcatheter closure in the unilateral absence of a pulmonary artery(UAPA) combined congenital heart diseases.Methods:From January 2005 to April 2009,multi-slice spiral CT or angiogram confirmed the diagnosis of UAPA in 5 patients(1 boy and 4 girls),including 4 patients with patent ductus arteriosus(PDA),1 with atrial septal defect(ASD);age(1.5-11) years old;1 cases of absence of the left and 4 cases of absence of the right,the main symptoms w...
