Extrahepatic portal vein aneurysm (PVA) is very rare with only 17 previously reported cases. Methods of treatment include resection, thrombectomy, and portal venous decompression. We report herein the first case of large PVA with thrombosis which has been managed without surgical treatment over a long period. A PVA was detected in a 78-year-old woman by abdominal ultrasonography. Computed tomography revealed an aneurysm of 6 cm in a diameter in the porta hepatis. Portal venography showed obstruction of the portal vein and developed collateral vessels around the aneurysm. Since the patient had no symptoms of portal hypertension, we decided to carefully manage her clinical course without surgical treatment. At present, this patient is healthy and has developed no complications over the 5 years since leaving our hospital. This case suggests that surgical treatment is not required for PVA without portal hypertension.
肝外门静脉瘤（PVA）非常罕见，此前仅有17例报道。治疗方法包括切除术、血栓切除术和门静脉减压术。我们在此报告首例伴有血栓形成的大型PVA病例，该病例长期未进行手术治疗。一名78岁女性通过腹部超声检查发现了PVA。计算机断层扫描显示肝门处有一个直径6厘米的动脉瘤。门静脉造影显示门静脉阻塞，并在动脉瘤周围形成了侧支血管。由于该患者没有门静脉高压症状，我们决定在不进行手术治疗的情况下仔细观察其临床病程。目前，该患者身体健康，自出院5年来未出现任何并发症。该病例表明，无门静脉高压的PVA无需手术治疗。
