Intracranial Aneurysms with Third Nerve Palsy

Abstract

To present our experience of embolization for the treatment of intracranial aneurysms with third nerve palsy, we analyzed 15 patients with posterior communicating artery aneurysms presenting third nerve palsy. Nine had subaracnoid hemorrhage.

In all of them a packing of aneurysm with different types of coils was performed. We employed in 4 cases coils with fibers, in 4 tungsten spirals and in 7 cases GDC coils.

Most posterior communicating artery aneurysms are bilobulated. We have tried to pack and close the first lobulation of aneurysm and so we tried to deposit the less coils than possible. The mean time of recovery was 2.5 months: 1–5 months if the aneurysm was packed only in its first lobule and 3 months if the technical difficulties forced complete packing of the aneurysm. Although this is not a large series, it is significant and shows that the excellent recovery in all cases does not contraindicate aneurysm embolization with coils in patients with third nerve palsy. The bilobulated aneurysms in which we packed the first lobulation completely have a faster recovery.
