[Endovascular embolization of a splenic aneurysm and of a false aneurysm of the splenic artery].

Splenic artery aneurysms, once considered rare entities are now being reported with increasing frequency. Rupture may be the presenting and only symptom and can be fatal. The authors present two cases of splenic aneurysms treated by endovascular embolization. The initial imaging work-up included sonography, angiography and helical computed tomography with multiplanar and 3D reformations. This enabled comprehensive evaluation of the aneurysms, including their configuration, essential for coil selection. Embolization was uneventful. Post-embolization angiograms confirmed exclusion of the aneurysms. Follow-up CT at 9 months showed complete thrombosis of the aneurysms and no evidence of pancreatic or splenic complication. Endovascular management for definitive treatment of splenic aneurysms is technically possible and should be considered.
