Venous aneurysms are less common than arterial aneurysms in clinical practice, and the occurrence of isolated cases is a topic for publication. Aneurysms of the superior mesenteric vein are rare, and their origin is unknown. Many aneurysms are asymptomatic, and the diagnosis is established from radiologic findings. Others are diagnosed after complications such as gastrointestinal bleeding or thrombosis with associated abdominal pain. Because of the rarity of this disease and consequent absence of standard treatment, therapy must be adapted to fit each case. We present a case report of an aneurysm of the superior mesenteric vein. The diagnosis of this anomaly was made after investigation of abdominal pain. Computed tomography (CT) scans demonstrated the mass. Clinical treatment was administered, and no aneurysm growth was observed after 5 years of follow-up.
在临床实践中，静脉瘤比动脉瘤少见，孤立病例的发生是一个可供发表的话题。肠系膜上静脉瘤罕见，其病因不明。许多动脉瘤无症状，通过影像学检查确诊。其他则在出现诸如胃肠道出血或血栓形成伴腹痛等并发症后才得以诊断。由于这种疾病罕见且缺乏标准治疗方法，治疗必须因人而异。我们报告一例肠系膜上静脉瘤病例。该异常情况是在对腹痛进行检查后确诊的。计算机断层扫描（CT）显示了肿块。给予了临床治疗，随访5年后未观察到动脉瘤增大。
