In this study, researchers examined the changes in related indicators such as immune function, splenic vein,proper hepatic artery, and portal venous hemodynamics following laparoscopic resection of a splenic artery aneurysm. We determined the changes in these patient-related indicators after surgical treatment and whether these changes could improve patient outcomes.

Patients with Splenic Artery Aneurysm were recruited in accordance with the research inclusion criteria, and their general demographic information was collected. After thorough preoperative preparation, the same surgical team performed laparoscopic resection of the splenic artery aneurysm. Postoperatively,the same nursing team provided standardized care. Subsequently, patients received a standardized postoperative treatment protocol, which included pharmacotherapy, additional therapeutic interventions, and follow-up visits. During the treatment period, routine blood tests,liver function tests, coagulation function,immune function, as well as the hemodynamics of the portal vein, proper hepatic artery, and splenic vein were monitored preoperatively and at 7 days, 1 month, 3 months, 6 months, and 12 months postoperatively.

Inclusion Criteria:

• Asymptomatic splenic artery aneurysms with a diameter>2 cm,ruptured splenic artery aneurysms,and splenic artery aneurysms with a diameter increase>0.5 cm/year.

Aneurysm located in the main trunk of the splenic artery. Informed consent to participate in the study.

Exclusion Criteria:

• Patients with malignancies Hepatic cirrhosis with portal hypertension peptic ulcer disease Recent peptic ulcer disease History of Hemorrhagic stroke Pregnancy hematological diseases Uncontrolled Hypertension Human immunodeficiency virus (HIV) infection
