Objective To investigate the influence factor of the recovery time of oculomotor nerve palsy (ONP) after traumatic carotid-cavernous sinus fistula (TCCF) treated by balloon embolization.Methods The clinical data of 76 patients with ONP after TCCF were retrospectively analyzed.All patients accepted intravascular balloon embolization treatment.Nonparametric test was applied to make single factor analysis of the influence factor of ONP recovery time,and linear regression analysis was applied to make multiple factor analysis.Results Seventy-six patients (100.0％) had a perfect occlusion for orificium fistulae after operation immediately,and 73 patients (96.1％) retained the internal carotid artery.Patients were followed up for 6-70 months,with an average of 34.2 months and no death cases.Seventy patients (92.1％) succeeded for embolization at the first time,and 6 patients (7.9％) relapsed after embolization for 6 weeks.The reasons of relapse was balloon leak,and no patients recurred after twice embolization.Seventy-six patients (100.0％) had recovery from ONP,and recovery time was (42.17 ± 32.39) d.The single factor analysis showed that the courses of diseases,fistula location,eye-tubercle location,degree of ONP,balloon quantity,state of internal carotid artery were the factor affecting the ONP recovery time (P ＜ 0.01 or ＜ 0.05).The linear regression analysis showed that the courses of the disease,fistula location,degree of ONP,balloon quantity were independent factor affecting the ONP recovery time (P ＜ 0.01).Conclusions Intravascular balloon embolization in the treatment of ONP after TCCF is safe and reliable.The courses of diseases,fistula location,degree of ONP and balloon quantity are the influencing factor of the oculomotor nerve functional recovery time,and should be given enough attention.

Objective To investigate the clinical significance of leukocyte count and neutrophil count change on delayed traumatic intracranial hemorrhage(DTIH).Method Collected the peripheral venous blood of l 16 eases of DTIH and 123 cases of non-DTIH between June 2005 and Deeember 2007.Compared the leukocyte count and neutrophil count in all cases by different groups.Results The leukocyte count and neutrophil count of the DTIH patients whose first CT scan were negative[(13.35±6.72)×109/Land(12.78±6.43)×109/L,respectively]were significantly higher than those of head injury whose CT scan werenegative allthetime[(9.72±3.09)×109/Land(7.64±2.93)×109/L,respectively].The difference was significant (P＜0.01).There were no statistical significance of the leukocyte count and neutrophil count between DTIH patients and non-DTIH patients whose first CT scan were positive(P＞0.05).Conclusions As an independent guideline,the leukocyte count and neutrophil count may help the forepart diagnosis of DTIH patients whose first CT scan were negative.
