The benefit of endovascular treatment for oculomotor nerve palsy due to posterior communicating artery aneurysms is still debatable. We reviewed the outcome of old aged (≥65) patients with ONP after coiling, retrospectively.
Between January 2001 and December 2010, the total of 62 patients underwent coiling for posterior communicating artery aneurysms. 8 of 13 patients with ONP were over than 65 years old at the time of coiling. Patient data were obtained from medical chart, medical files, clinical presentation, endovascular procedure note, out-patient department (OPD) chart and operation reports.
Complete recovery was observed in 2 patients (25%). And partial recovery was noted in 4 patients (50%). Complete recovery patients did not have history of microvascular risk factor. However, 4 of 6 patients with remained ONP (66.7%) had history of microvascular risk factor. ONP was recovered completely in 2 out of 2 patients (100%) with partial ONP while 0 out of 6 patients with complete ONP were recovered fully from the symptom.
The initial degree of ONP and the microvascular risk factor may be influence on the outcome in old aged patients.
