A 39-year-old Japanese woman was diagnosed with a pulmonary arteriovenous fistula (PAVF) complicated by paradoxical cerebral infarction during pregnancy. She received an inferior vena cava filter (IVCF), but it was difficult to indwell because of the risk of repeat thromboembolism via PAVF. Therefore, we temporarily occluded the pulmonary artery with a balloon to prevent free thrombi from reaching the IVCF. Detection and treatment of PAVF are recommended in fertile young women. Obstruction of the pulmonary artery trunk with a balloon catheter may be useful during IVCF removal in patients with untreated PAVF.
一名39岁的日本女性在孕期被诊断为患有肺动静脉瘘(PAVF)并并发反常性脑梗死。她接受了下腔静脉滤器(IVCF)植入,但由于存在经PAVF再次发生血栓栓塞的风险,滤器植入困难。因此,我们用球囊临时阻塞肺动脉,以防止游离血栓到达IVCF。建议对育龄期年轻女性进行PAVF的检测和治疗。对于未治疗的PAVF患者,在取出IVCF期间,用球囊导管阻塞肺动脉主干可能是有用的。
