Dissecting aneurysm at the proximal anterior cerebral artery treated by parent artery occlusion.
Aneurysms of the A1 segment of the anterior cerebral artery (ACA) are rare. We described the first documented endovascular treatment of an A1 portion dissecting aneurysm by parent artery occlusion. A 43-year-old man patient presented with subarachnoid hemorrhage. Cerebral angiography demonstrated a dissecting aneurysm of the left anterior cerebral artery (ACA) at A1 portion. Because of the dissecting nature of the A1 portion aneurysm, a 2.5x15-mm Neuroform stent was placed in the left A1 portion. However, regrowth of the aneurysm was found on the three month follow-up angiogram, so the aneurysm and the left A1 portion of ACA were occluded completely.
