ABSTRACT
We retrospectively analyzed clinical and imaging data of 26 children with split cord malformations (SCMs). Based on Pang's classification, 14 SCMs were defined as type Ⅰ and 12 as type Ⅱ.Neural function was markedly improved in 20 patients postoperatively. Three of 4 children who did not undergo surgical treatment had neural function deteriorated. Two children lost follow-up. We suggest that Pang's Classification of SCMs may be useful in describing pathological changes and guiding surgical procedure; imaging examine (including MRI, CT and X-ray) would play a significant role in confirmed SCMs diagnosis; and surgical operation should focus on eliminate and prevent spinal cord damnification.
ABSTRACT
OBJECTIVE To study the risk factors of neurosurgical postoperative intracranial infection.METHODS Totally 5405 patients who had a neurosurgical operation from 1996 to 2003 in our department were chosen(172(cases) with intracranial infection).Many risk factors were studied retrospectively,A data-base was set up with EXCEL,and Logistic regression was selected to analyze the factors which might cause infection.RESULTS The(analysis) of 5405 cases revealed that infection rate was closely related to the operation durations,CSF fistulae,(ventricle) drainage,the insertion of tubes,the approach to the post fossa,the complication from diabetes mellitus(DM),and open(craniocerebral) injuries.While had little effect of sex,age,the season,longer application of hormones before the operation,preoperative diseases,and longer application of antibiotics before or after the operation.(CONCLUSIONS) To decrease the infection rate,according the clinical experience,the operation should be finished as soon as possible,the suture should be done completely to prevent CSF fistulae,and the duration of the ventricle drainage should be controlled strictly.
ABSTRACT
Objective: To obtain anatomical parameters for surgery of the cavernous sinus. Methods:The anatomical study of nerves and triangles of the cavernous sinous was made in 15 adult cadaver brians by microanatomical methods. Results: Ten triangles of the cavernous sinus and 3rd cranial nerve, 4th cranial nerve in each cavernous sinus were studied. It was discovered that almost all content could be shown through Hakuba triangle and Parkinson triangle. Conclusion: The anatomical parameters of cavernous sinus is obtained, it is useful for surgical treatment of cavernous diseases. [
ABSTRACT
Objective To measure anatomical parameter of internal carotid artery in petrous bone, and provide anatomical basis for operations Methods The anatomical study of the internal carotid artery (ICA) in petrous bone and related landmarks was studied in 15 adult cadaver brain specimens under the microscope Results The petrous segment of the ICA can be divided into ascending,bend and horizontal portion The great superficial petrous nerve was the best landmark through which the petrous segment of ICA can be exposed in operations. Conclusions If we are familiar with the anatomy of the petrous segment of the ICA and related landmarks,the petrous segment of the ICA can be protected very well in operations with less complications and better prognosis.
