Laparoscopic surgery of the splenic artery and vein aneurysm with spontaneous arteriovenous fistula.

Visceral artery aneurysms are rare and important vascular entities due to the quarter of all cases presented as surgical emergency. Nevertheless, splenic artery aneurysm (SAA) is the most common visceral and third most common intra-abdominal artery aneurysm after aorta and iliac artery. SAA accompany splenic vein aneurysm because arteriovenous fistula communication between them is a very rare entity. Location and size of the SAA determine the likelihood of rupture. Women of child-bearing age who have SAAs are at particularly high risk of death as a result of aneurysm rupture and should be treated with elective repair. Herein, we report a case of a splenic artery and vein aneurysm with arteriovenous fistula in a 25-year-old young female patient who presented with left upper quadrant pain. Diagnosis was established by computerized tomography angiogram. The patient underwent laparoscopic resection of splenic artery and vein, as well as with splenectomy. Laparoscopic therapy for SAA should be considered for the patient with a low periprocedural morbidity at experienced surgical clinics.
