We found splenic artery aneurysms in 6 of 71 consecutive patients who underwent orthotopic liver transplantation at the Mayo Clinic. The incidence of splenic artery aneurysms in cirrhotic patients with portal hypertension was 10%. Five of the aneurysms were found in patients suffering from chronic active hepatitis, whereas no aneurysms were encountered in patients with primary sclerosing cholangitis or primary biliary cirrhosis. One patient ruptured a splenic artery aneurysm shortly after liver transplantation, and 1 patient developed an aneurysm 3 months after transplantation. We recommend coeliac angiography to be performed prior to liver transplantation, and if splenic artery aneurysms are found, ligation of the splenic artery should be performed at the time of transplantation to prevent possible rupture.
在梅奥诊所接受原位肝移植的71例连续患者中，我们发现了6例脾动脉动脉瘤。门静脉高压肝硬化患者中脾动脉动脉瘤的发生率为10%。其中5例动脉瘤见于慢性活动性肝炎患者，而原发性硬化性胆管炎或原发性胆汁性肝硬化患者未发现动脉瘤。1例患者在肝移植后不久脾动脉动脉瘤破裂，1例患者在移植后3个月出现动脉瘤。我们建议在肝移植前进行腹腔动脉造影，如果发现脾动脉动脉瘤，应在移植时结扎脾动脉以防止可能的破裂。
