Oculomotor palsy and supraclinoid internal carotid artery aneurysms. Personal experience and review of the literature.

Oculomotor palsy related to the presence of an intracranial aneurysm arising from the supraclinoid internal carotid artery (ICA) is a well known and described clinical condition. Recent microanatomical and clinical evidences seem to demonstrate that the pathophysiology of the aneurysm-related III nerve palsy could be interpreted as that of any other cranial nerve's neurovascular compression syndrome. The authors review their personal experience with supraclinoid ICA aneurysms related to oculomotor palsy and the data of the literature, aiming to elucidate a better clinical, therapeutic and prognostic correlation to these factors.
