Embolization of a splenic artery aneurysm: a case report

Splenic artery aneurysm (SAA) is the most common aneurysm of the visceral arteries. SAA can be silent and asymptomatic; rupture is a rare but serious complication that can manifest as acute diffuse abdominal pain and hypovolemic shock with a high risk of mortality. Surgery is the traditional treatment, but has the disadvantage of severe surgical injuries, a high risk of complications and a high mortality rate. We present the case of a 58-year-old woman with a saccular aneurysm of the middle segment of the splenic artery; she was treated by coiling embolization using the sandwich technique. Contrast-enhanced computed tomography (CECT) controls at one month, four months and one year showed progressive reduction and complete devascularization of the aneurysmal sac. Embolization of the splenic artery aneurysm is an effective and safe treatment.
