Optimal treatment for ruptured dissecting basilar artery aneurysms in patients presenting with SAH is endovascular method using stent placement and coil embolization. We report a case (52-year-old woman) of ruptured dissecting aneurysm of the basilar artery which was treated with stent placement and coil embolization.
A 14-year old boy was admitted with stuporous mentality. CT scan, MRI and cerebral angiogram revealed SAH and a giant aneurysm of right middle cerebral artery(4x5x5.3cm). To minimize surgical risk, endovascular treatment was done with MDS(mechanical detachable system)-spiral coil. Follow up MRI showed intraluminal thrombus formation of the aneurysm.
