ObjectiveTo investigate the preventive strategy of early post-operative complications of closed spinal dysraphisms in children.MethodsOne hundred and nine children with closed spinal dysraphisms underwent surgery from January 2004 to December 2008,were enrolled in this study.After dural closure,the wound was washed completely with saline to clear the tissue debris to prevent postoperative infection. We routinely made a horizontal incision to prevent postoperative infection. Results After operation,all patients were recovered and were discharged from hospitalNo post-operative complications,including cerebrospinal fluid leakage, wound infection and flap necrosis, were encountered. ConclusionThe sophisticated microsurgical technique and the delicate surgical manipulation is the prerequisite for the prevention of early operational complication of closed spinal dysraphisms in children.

Within three years ,86 cases of tumors in the pineal region were treated by X－ Knife radiosurgical technique,using the standard axial serial CT scan for stereotactic localization,the target were localized by the BRW coordinate system.Radionics RSA－ 3 X－ Knife treatment planning system were used to make plan,Philips SL－ 75－ 14 Linac was used to produce X－ ray.After treatment, follow－ up ranged 6～ 42 months (meanly 24 months),most of the patients showed improvements within 1｀ 6 months. The results of this report proved that the X－ Knife treatment for tumors in the pineal region might be an effective,economical and reliable method.
