Emergency preoperative embolization using coils of ruptured sylvian aneurysm. Apropos of a case]

The authors report a case of a 73 year old patient who presented with a right temporal lobe hematoma secondary to rupture of a right middle cerebral artery bifurcation aneurysm. Treatment consisted of partial thrombosis of the aneurysm by the endovascular introduction of metallic coils followed by surgical hematoma evacuation and aneurysm clipping. Thrombus of the aneurysm done probably diminished the risk of intraoperative rupture. Partial endovascular treatment has a very small risk and may be done on a emergency basis at the same time as the diagnostic arteriogram. It can also be suggested for patients in poor condition to diminish the risk of recurrent hemorrhage until the patient is well enough to undergo definitive surgical clipping.
