True splenic artery aneurysms (SAA) are a rare, but potentially fatal, pathology. They are the third most common type of abdominal aneurysm, after aneurysms of the aorta and of the iliac artery, and account for almost the all aneurysms of visceral arteries. True aneurysms account for 60% of SAA and affect four times as many women as men, generally related to increased incidental or symptomatic findings that coincide with use of ultrasonography in pregnancy. Among pregnant patients, mortality after rupture is 65-75%, with fetal mortality exceeding 90%. There are multiple etiologies and it is believed that hormonal influences and changes in portal flow during gestation play an important role in development of SAA. This review discusses their history, epidemiology, pathophysiology, and diagnosis and current treatment techniques.
真性脾动脉瘤（SAA）是一种罕见但可能致命的病变。它是继主动脉瘤和髂动脉瘤之后第三常见的腹主动脉瘤类型，几乎占所有内脏动脉瘤的比例。真性动脉瘤占脾动脉瘤的60%，女性患者是男性患者的四倍，这通常与孕期超声检查中偶然发现或有症状的情况增加有关。在孕妇中，破裂后的死亡率为65%-75%，胎儿死亡率超过90%。病因多种多样，人们认为孕期激素影响和门静脉血流变化在脾动脉瘤的发展中起重要作用。本综述讨论了它们的历史、流行病学、病理生理学、诊断及当前的治疗技术。
