目的:报道通过结扎部分体肺侧支循环治疗1例单纯性一侧肺动脉缺如(UAPA),并对国内一段时间内的病例资料作一回顾。方法:患者为3岁男孩,以反复右肺感染合并间断咯血收治入院,血管造影提示为单纯性右肺动脉缺如,伴大量右侧体肺侧支循环形成。通过手术结扎部分体肺侧支循环治疗患儿咯血。结果:患儿术后恢复顺利,咯血症状消失,随访半年无复发。结论:结扎部分体肺侧支循环是治疗小儿以咯血为主要症状的UAPA的可行方法。UAPA通常可以通过心血管造影、CT和MRI获得确诊,掌握适当的诊断技术,是进行满意治疗的基础。
OBJECTIVE: To report a case of simple unilateral pulmonary artery defect (UAPA) by ligating some of the body collateral circulation in the lung and to review the case data in China for a period of time. Methods: The patient was a 3-year-old boy admitted to hospital with repeated right-lung infection complicated with intermittent hemoptysis. The angiography showed that the right pulmonary artery was absent, with a large number of right collateral circulation forming. Hemoptysis of pediatric hemoptysis was performed by surgical ligation of part of the lung collateral circulation. Results: The recovery of children with postoperative success, hemoptysis disappeared, no recurrence six months follow-up. Conclusion: Ligation of some of the body’s collateral circulation is a viable method for the treatment of UAPA in children with hemoptysis as the main symptom. UAPA is usually diagnosed by cardiovascular angiography, CT and MRI, and proper diagnostic techniques are the basis for satisfactory treatment.
