Abstract

Background: Pulmonary arteriovenous malformation (PAVM) is abnormal arteriovenous shunts between pulmonary artery (PA) and pulmonary vein, and rarely has congenital direct communications with systemic arteries.

Case presentation: A 33-year-old male presented to our hospital with intermittent bloody sputum with no evidence of pulmonary infection, trauma or surgery. Chest computed tomography angiography (CTA) indicated the congenital inferior phrenic artery (IPA)-to-PAVM surrounded by diffuse alveolar hemorrhage located in the lower lobe of right lung. Both the afferent PA and IPA were successfully embolized with coils. Recurrent hemoptysis did not occur during one-year follow up.

Conclusions: The congenital communication between IPA and PAVM is rare, and the abnormal direct shunt would induce hemodynamically unstable condition within PAVM. Endovascular embolization of the afferent PA and IPA is a safe and effective method for this abnormal congenital shunt in lung.

先天性膈下动脉至肺动静脉畸形的血管内栓塞术：罕见病例报告。

背景：肺动静脉畸形（PAVM）是肺动脉（PA）和肺静脉之间的异常动静脉分流，很少与全身动脉有先天性直接沟通：一名 33 岁的男性因间歇性血痰来我院就诊，无肺部感染、外伤或手术迹象。胸部计算机断层扫描血管造影（CTA）显示，位于右肺下叶的先天性膈下动脉（IPA）-to-PAVM 周围有弥漫性肺泡出血。用线圈成功栓塞了传入PA和IPA。在一年的随访期间，没有再发生咯血：结论：IPA与PAVM之间的先天性沟通非常罕见，异常的直接分流会导致PAVM内血流动力学不稳定。血管内栓塞传入 PA 和 IPA 是治疗肺部先天性异常分流的一种安全有效的方法。
