Role of micro-neurosurgery training in the cultivation of specialty degree neurosurgery post-graduates / 中华医学教育探索杂志

Taking microneurosurgery approach and applied surgical anatomy training as the core and combining theoretical teaching and perioperative training as the main contents , training program achieved significant effect among specialty degree neurosurgery postgraduates. In order to further improve the quality of training, it is proposed to set up micro-neurosurgery training center and more complete train-ing system based on micro-neurosurgery contents thus to improve clinical ability of specialty degree neuro-surgery postgraduates.

Radiological diagnosis of brainstem cavernous malformations and their micro-neurosurgical treatment outcomes / 中华神经医学杂志

Objective To investigate the radiological characteristics of brain stem cavernous malformations and their micro-neurosurgical treatment outcomes.Methods A retrospective analysis of radiological characteristics and micro-neurosurgical treatment outcome of 15 patients with brain stem cavernous malformations,admitted to our hospital from May 2006 to September 2011,was performed.Results Distinctive features of patients with brain stem cavernous malformations were noted under MRI,showing mulberry-like or Lattice-shaped structures; low signal ring was noted around the tumors;T2WI enjoyed the most obvious signal,indicating remote hemorrhage resulted from hemosiderin deposition.All patients underwent entire resection of brainstem cavernous malformations except for one patient sub-entire resection.One week after the operation,the neurological status was improved in 12 patients,remained unchanged in 2 patients,and aggravated in 1 patient.Three months after the operation,the neurological status was improved in 13 patients and remained unchanged in 2 patients.Among the 12 patients undergone follow-up 12 months after operation,the neurological status was improved in 11 patients and remained unchanged in 1 patient.Conclusion MRI is reliable in the diagnosis of brainstem cavernous malformations; the position and size of cavernous hemangioma could be displayed clearly; micro-neurosurgical treatment can provide good outcome for patients with symptoms.

Small Craniotomy Lateral Fissure Approach and Technique of Micro-neurosurgery for Treatment of Morderate or Severe Intracerebral Hemorrhage from Putamen / 中国医师杂志

Objective To explore clinical effects of micro-nurosurgical treatment with small craniotomy lateral fissure approach to treat moderate or severe intraceral hemorrhage from putamen.Methods All of 51 patients with moderate or severe intracerebral hemorrhage were subjected to surgical treatment.Scalp incision was approximate the projection of lateral fissure on head,the diameter of the window of bone was about 3cm.The lateral fissure was opened by anatomizing sylvian cistern.After incising the cortex of insular,hemotoma was removed.Results 11 cases were dead,the mortality was 21 57%.The ADL was accepted as a standard means of describing outcome in these patients .2 cases,were subjected to Grade Ⅰ,6 cases for GradeⅡ,15 cases for GradeⅢ,8 cases for Grade Ⅳ,2 cases for Grade Ⅴ.Conclusions There is no significant difference of outcome between small craniotomy and craniotomy.(Lateral fissure approach) Transsylvian route is very directly for deep hemotomas,and brain injury caused by approach also is very light.
