title: [Analysis of prognostic factors on posterior communicating artery aneurysm caused oculomotor nerve palsy].
abstract: OBJECTIVE
  To study and analyze the factors affecting the recovery of posterior communicating artery aneurysm-induced oculomotor nerve palsy (ONP).
  
  
  METHODS
  The clinical and follow-up data of posterior communicating artery aneurysm-induced ONP in 23 patients from May 2005 to May 2009 were retrospectively compared. There were 7 male and 16 female with a mean age of 50.4 years. Among the 23 patients, 13 patients underwent endovascular coiling (endovascular group) and 10 patients underwent surgical clipping (surgical group).
  
  
  RESULTS
  Of the patients with 2 year of follow-up, 6 patients recovered completely and 7 patients recovered partially in the endovascular group, compared with 6 patients recovered completely and 4 patients recovered partially in the surgical group (P = 0.407). Compared to the patients with preoperative complete ONP, the rate of complete recovery was higher in the patients with preoperative partial ONP, while the results did not reach the significance (P = 0.095). Patients accepted treatment in 14 days since the onset of symptoms recovered significantly than who accepted treatment after 14 days since the onset of symptoms (P = 0.045).
  
  
  CONCLUSIONS
  There is no significant difference in recovery from ONP between endovascular coiling and surgical clipping as treatment for posterior communicating artery aneurysm patients with ONP. Timing of treatment after onset of symptoms is a factor affects the recovery of ONP.
