Objective. The aim of our work was to evaluate the immediate and remote results of ligation of splenic artery aneurysm in orthotopic liver transplantation in patients with decompensated liver cirrhosis.Material and methods. From June 2018 to May 2024, 232 liver transplants from a posthumous donor were performed at the Surgical Clinic of the Moscow Multidisciplinary Scientific and Clinical Center n.a. S.P. Botkin. In 4 patients (1.7%), the presence of aneurysmal dilatation of the splenic artery was revealed at the preoperative stage. During orthotopic liver transplantation, patients underwent ligation of the splenic artery proximal and distal to the aneurysms.Results. Mean time for the isolation and ligation of the splenic artery aneurysm was 18.4±3.3 minutes. In no case was there any damage or bleeding from either the branches or the aneurysm of the splenic artery; and there was no damage to the spleen. No adverse events related to the splenic artery aneurysm ligation were recorded in either early or late postoperative periods. In all cases, the control examination did not reveal any ischemic changes in the splenic parenchyma.Conclusion. Ligation of the splenic artery aneurysm during orthotopic liver transplantation is a safe, effective and necessary surgical intervention that can improve long-term results by reducing the risk of death from aneurysm rupture in the postoperative period.
