Splenic Arteriovenous Fistula with Pseudoaneurysm

Abstract

DOI https://doi.org/ 10.1055/s-0041-1726656 ISSN 2581-9933 A 24-year-old male patient with a history of laparoscopic splenectomy presented to the outpatient clinic with pain and fullness in the left upper quadrant of the abdomen. Physical examination and laboratory results were unremarkable. Contrast-enhanced computed tomography (CT) showed aneurysm with a maximum diameter of 30 mm on the distal part of the tortuous splenic artery and splenic arteriovenous fistula and early opacification of the splenic vein (►Fig. 1A, B). Three-dimensional CT reconstruction revealed aneurysm and connection between the splenic artery and vein (►Fig. 1C). Aneurysm was interpreted in favor of pseudoaneurysm in the case with a splenectomy history. Splenic artery pseudoaneurysm with splenic arteriovenous fistula infrequently occurs as a complication of splenectomy. Rupture and portal hypertension are potential complications. This patient subsequently underwent endovascular intervention, treated with coil embolization, and has continued to do well on clinical follow-up visits.
