Pulmonary vein thrombosis (PVT) is rarer than pulmonary artery thrombosis (PAT). PVT is potentially fatal but is often overlooked due to its nonspecific symptoms. We present a case with PVT accompanied by paroxysmal atrial fibrillation. The symptoms were limited to transient ischemic attacks. Contrast-enhanced computed tomography (CT), which showed a thrombus in the right pulmonary vein trunk, was useful in diagnosing PVT. After switching the patient's anticoagulant from dabigatran etexilate to apixaban, the thrombus disappeared within 5 months. Contrast-enhanced CT is a useful and common tool for diagnosis and follow-up of PVT.
肺静脉血栓形成（PVT）比肺动脉血栓形成（PAT）更为罕见。PVT可能致命，但因其症状不具特异性，常被忽视。我们报告一例伴有阵发性心房颤动的PVT病例。症状仅限于短暂性脑缺血发作。对比增强计算机断层扫描（CT）显示右肺静脉主干有血栓，对诊断PVT很有用。将患者的抗凝剂从达比加群酯换成阿哌沙班后，血栓在5个月内消失。对比增强CT是诊断和随访PVT的一种有用且常用的工具。
