Endovascular Occlusion of Congenital Portosystemic Shunts: Technical Success and Clinical Outcomes—A Case Series

Abstract The aim of the study is to report the outcomes of endovascular management of congenital portosystemic shunts (CPSS) in three patients. This is a retrospective review of three patients who underwent transcatheter shunt closure for CPSS between 2023 and 2025. Pre- and post-procedure imaging, procedural details, and clinical follow-up were analyzed. Successful shunt closure was achieved in all three cases with significant improvement in hyperammonemia, pulmonary arterial hypertension, and hepatopulmonary syndrome. There were no procedure-related complications. Endovascular closure of CPSS is safe and effective in selected patients, offering good outcomes and low morbidity when guided by precise imaging and hemodynamic evaluation.
