Microsurgical Treatment for Posterior Communicating Artery Aneurysms Associated with Oculomotor Palsy

Objective To explore the curative effect of microsurgical treatment for posterior communicating artery aneurysms associated with oculomotor palsy.Methods The clinical data of 52 patients with posterior communicating artery aneurysms associated with oculomotor palsy treated microsurgically from January 2008 to December 2010 were retrospectively analyzed.Recovery of oculomotor palsy was observed,and clinical experiences were summarized.Results The follow-up time ranged from 3 to 36 months with a mean period of 16 months.Among the 34 patients operated on within 14 days after the onset of oculomotor palsy,22(64.7%) showed complete recovery,and 12(35.3%) partial recovery.In the 18 patients operated on more than 14 days after the onset of the disease,6(32.3%) showed complete recovery,and 12(67.7%) partial recovery.Incomplete palsy occurred in 15 patients among whom 12(80%) had complete recovery and 3(20%) alleviation.Among the other 38 patients with complete oculomotor palsy,only 11(29.7%) got complete recovery,and the remaining 26(70.3%) partial recovery.Conclusion Early and positive diagnosis and treatment of patients with posterior communicating artery aneurysms associated with oculomotor palsy is of great importance to the nerve function recovery.
