Congenital portosystemic shunt with multiple splenic artery aneurysms

Abstract

We report an unusual occurrence of multiple splenic artery aneurysms and splenomegaly in a young woman with severe pulmonary hypertension, secondary to a congenital portosystemic shunt (CPS). The splenic artery was occluded using an Amplatzer Duct Occluder-II device, and closure of the large intrahepatic CPS was achieved using a muscular ventricular septal defect occluder. There was resolution of splenomegaly with normal pulmonary artery pressures, a few months after the procedure.

Open surgical approach for two coincidental splenic artery aneurysms: a case report

“…

Several factors can contribute to the formation of aneurysms, including hemodynamic changes, polyarteritis nodosa, bacterial endocarditis, vasculitis, fibromuscular dysplasia, vascular malformation, and cystic medial necrosis. [1,2] Surgery is recommended for splenic artery aneurysms (SAAs) greater than 25 mm in diameter, and several surgical approaches are used, including open surgery, laparoscopic surgery, and percutaneous embolization. Laparoscopic surgery might be associated with an increased risk of pancreatic leakage compared to the open surgery approach.
