| PurposeThis study was conducted to investigate the postoperative recovery of patients with posterior communicating aneurysm complicated with oculomotor nerve palsy (ONP) and to analyze the factors influencing length of recovery.MethodsFrom 2006 to 2008, eighty-six patients with posterior communicating aneurysm were treated at our hospital, with 32 of them having concurrent unilateral oculomotor palsy. All of the patients underwent pedicle clipping after the diagnosis by means of 3D-CTA or DSA. We followed up the degree of oculomotor nerve postoperative recovery one year. The patients were divided into two groups for observation of postoperative recovery during the follow-up period. Patients in group A were partial oculomotor recovery while patients in group B were complete oculomotor recovery.ResultsOf the 15 patients in group A, the mean age was 59.1±6.9 years,3 patients were partial oculomotor palsy while 12 patients were complete oculomotor palsy before surgery, the mean interval between the onset of ONP and treatment was 6.8±3.2 days. In group B, there were 17 patients, the mean age was 52.2±8.2 years,11 patients were partial oculomotor palsy while 6 patients were complete oculomotor palsy before surgery, the mean interval between the onset of ONP and treatment was 4.4±2.4 days.ConclusionsEarly diagnosis and surgical treatment of patients with ONP induced by posterior communicating aneurysm are important for postoperative recovery of the oculomotor nerve. Age and the degree of oculomotor palsy are the important factors of oculomoter nerve recovery. |
