Aneurysmal disease in the venous system is uncommon. The majority of venous aneurysms occur in peripheral vessels. Visceral venous aneurysms (VVA) are rare, the most common being portal mesenteric vein aneurysms. Because of their rare nature, limited information concerning the natural history, presentation, and management of VVA is known. Many VVA are asymptomatic; others cause mass effect or other complications. Rupture is a rare complication, occurring in only 2.2% of VVA. To date, only 17 descriptions of superior mesenteric vein (SMV) aneurysms have been reported. We report the first case of a ruptured SMV aneurysm.
静脉系统的动脉瘤性疾病并不常见。大多数静脉动脉瘤发生在外周血管。内脏静脉动脉瘤（VVA）很少见，最常见的是门静脉肠系膜静脉动脉瘤。由于其罕见性，关于VVA的自然病史、临床表现和治疗的信息有限。许多VVA是无症状的；其他的则会引起占位效应或其他并发症。破裂是一种罕见的并发症，仅发生在2.2%的VVA中。迄今为止，仅报道了17例肠系膜上静脉（SMV）动脉瘤的描述。我们报告了首例破裂的SMV动脉瘤病例。
