Abstract

Oculomotor nerve palsy (ONP) may result from Posterior communicating artery (Pcom) aneurysms. Endovascular treatment of ruptured Pcom aneurysms generally is a safe procedure, but the effect of this therapy on ONP is incompletely elucidated. This retrospective study evaluates outcomes of ONP after endovascular treatment for ruptured Pcom aneurysm and with the intention to clarify predictors of recovery. From May 2010 to October 2015, 210 patients with Pcom aneurysms underwent endovascular treatment at our institution. Among them, 34 patients with ruptured aneurysms and either complete or incomplete ONP were identified. The outcomes and predictors of ONP recovery were analyzed. At the last available clinical follow-up, ONP resolution was complete in 21 (61.8%) patients and incomplete in 8 (23.5%) patients. The mean resolution time after embolization was 24.5 days. Five patients showed no signs of ONP recovery. In no case was an initial incomplete ONP observed to worsen. There was a statistically insignificant trend toward complete recovery among patients with initial incomplete ONP (OR = 4.17; 95% CI, 0.75–23.18; P = 0.103). Endovascular treatment appears to be an effective treatment modality for ruptured Pcom aneurysm and related ONP. The initial incomplete ONP might encourage complete ONP recovery after endovascular treatment.
