Splenic artery aneurysms (SAAs) are the third most common forms of intra-abdominal aneurysm, and the most commonly encountered visceral aneurysms in the general population. SAAs occur more commonly in patients with portal hypertension and liver failure and, as such, are often encountered in patients undergoing high-resolution abdominal imaging as part of a work-up for liver transplantation. While rupture rates of between 2% and 10% have been reported in the literature, little is known about the natural history and behavior of these lesions in patients with liver disease. Interventional management options pose a challenge given the high anesthetic and surgical risk of such patients. This study was conducted to study the management of all SAAs diagnosed among patients presenting for a liver transplant assessment at a single center over a three-yr period. We discuss the presentation and management options, with elective and emergent presentation of SAA in patients with end-stage liver disease.
脾动脉瘤（SAAs）是第三大常见的内脏动脉瘤，也是一般人群中最常见的腹内动脉瘤。SAAs 在门静脉高压和肝功能衰竭患者中更为常见，因此，在进行高分辨率腹部成像检查以进行肝移植评估的患者中经常遇到。虽然文献报道破裂率在 2%至 10%之间，但对于肝病患者中这些病变的自然史和行为知之甚少。鉴于此类患者的麻醉和手术风险较高，介入管理选择构成了挑战。本研究旨在研究在单个中心进行肝移植评估的患者中诊断出的所有脾动脉瘤的管理。我们讨论了 SAA 在终末期肝病患者中的表现和管理选择，包括择期和紧急表现。
