[Splenic artery aneurysm. Two successfully operated cases]

The splenic artery aneurysms usually have an asymptomatic course; their rupture is associated with high mortality. The clinical history and the treatment of two patients with splenic artery aneurysm are reported. Of the two cases, one was asymptomatic, diagnosed with upper abdomen ultrasound, the other one was treated as an emergency because presented with shock. Both patients underwent surgical procedure; ligature of the splenic artery and splenectomy were performed. Early diagnosis is important in these lesions because the progressive enlargement and eventual rupture are the natural history. Ultrasonography (US) and computed tomography (TC) are very helpful as diagnostic tools, however angiography represents the method of choice since it could be the first step of the embolization treatment. If the diameter is more than 2.5 cm surgical treatment must be performed. Ruptures are treated with emergency operations, when possible. In high-risk patients non operative management by selective embolization may be a suitable alternative.
