Abstract:Objective To explore the clinical efficacy of endoscopic ultrasound-guided partial splenic artery embolization (EUS-PSE) in the treatment of portal hypertension and hypersplenism.Methods A retrospective analysis was conducted on the clinical data of 7 patients with portal hypertension and hypersplenism who underwent EUS-PSE from March 1, 2023, to August 31 2025. The therapeutic effects were evaluated.Results All 7 patients successfully completed EUS-PSE. All patients underwent splenic artery embolization using a combination of coils and sandwich tissue glue injection (3.0 mL of lauromacrogol + 0.5 mL of tissue glue+3.0 mL of lauromacrogol). Platelet counts significantly increased in 6 patients. None of the patients experienced perforation, bleeding, or ectopic embolization. One patient developed severe abdominal infection after the operation, which improved after 1 month of anti-infection treatment.Conclusion EUS-PSE is effective in treating portal hypertension and hypersplenism. However, close attention should be paid to splenic and abdominal infections.
