3rd Nerve Palsy After Microsurgical Clipping of Basilar Top Aneurysm

Postoperative oculomotor nerve palsy is a rare complication that occurs in the setting of micro¬surgical aneurysm clipping. While a number of theories have been postulated to explain the development of postoperative oculomotor nerve palsies, the underlying pathophysiology of such complications still remain to be elucidated. In this report, we present a case of postoperative isolated ipsilateral oculomotor nerve palsy after clipping of basilar tip aneurysm which we believe may be attributed to periperative oculomotor nerve manipulation related neuropraxia.
