Embolization of multiple splenic artery aneurysms in a patient with hypersplenism due to portal hypertension: a case report

Abstract

Aneurysms of the splenic artery are the third most common type of intra-abdominal aneurysms and the most common type of visceral aneurysms. Portal hypertension is a significant risk factor for development of these aneurysms. We report the case of a white, female, 52-year-old patient with multiple splenic artery aneurysms and hypersplenism secondary to portal hypertension and cirrhosis. Abdominal angiotomography identified six splenic aneurysms. In this scenario, an endovascular intervention was scheduled to conduct embolization using controlled release coils and Onyx™ embolization agent. The three largest aneurysms were treated. Control angiographs showed good exclusion of the aneurysms. The endovascular technique therefore proved to be a good choice considering the patient’s comorbidities and blood disorders. In this case, the procedure was successful. There were no immediate or long-term complications. The patient recovered well and is in clinical follow-up.
