Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between pulmonary arteries and pulmonary veins that are most commonly associated with hereditary hemorrhagic telangiectasia (HHT). The authors report a case of lobar artery embolization for the treatment of diffuse PAVMs in a patient with HHT who was experiencing recurrent transient ischemic attacks despite anticoagulation and multiple previous embolizations. The right lower lobar and interlobar arteries were embolized to achieve complete occlusion of multiple PAVMs in the right lower lobe and right middle lobe. In conclusion, lobar embolization can be considered for the relief of neurologic symptoms in patients with diffuse PAVMs.
肺动静脉畸形（PAVMs）是肺动脉和肺静脉之间的异常交通，最常与遗传性出血性毛细血管扩张症（HHT）相关。作者报告了一例 HHT 患者弥漫性 PAVMs 的肺叶动脉栓塞治疗病例，该患者尽管接受抗凝和多次先前栓塞治疗，但仍反复出现短暂性脑缺血发作。右下肺叶和叶间动脉被栓塞，以实现右下肺叶和右中叶多个 PAVMs 的完全闭塞。总之，对于弥漫性 PAVMs 患者，可考虑行肺叶栓塞以缓解神经症状。
