A 74-year-old woman presented with progressive dyspnea. Computed tomography revealed a large systemic artery-to-pulmonary artery vascular malformation (VM) on the right chest wall. Embolization of the VM was performed. First, the main drainers of the VM were retrogradely selected from the segmental pulmonary arteries and embolized using microcoils. Second, 2 main feeders of the VM were selected and embolized with N-butyl cyanoacrylate. Thus, marked flow reduction in the VM was achieved, and the patient's symptom improved dramatically. We believe that embolization of both feeders and drainers is an effective technique for treatment of a chest wall systemic artery-to-pulmonary artery VM.
一名74岁女性因进行性呼吸困难就诊。计算机断层扫描显示右胸壁存在一个大型体动脉至肺动脉血管畸形（VM）。对该VM进行了栓塞治疗。首先，从肺段动脉逆行选择VM的主要引流血管，并用微线圈进行栓塞。其次，选择VM的2条主要供血血管，用氰基丙烯酸正丁酯进行栓塞。由此，VM内的血流显著减少，患者症状明显改善。我们认为，对供血血管和引流血管同时进行栓塞是治疗胸壁体动脉至肺动脉VM的有效技术。
