Objective To compare the effect of lumbar shunt and complications of ventriculo peritoneal shunt on complications patients with communicating hydrocephalus.Methods A total of 130 patients with communicating hydrocephalus in our hospital from June 2011 to June 2016 were selected,who were randomly divided into two groups,including 62 cases in the experimental group and 68 cases in the control group.The experimental group was implemented lumbar peritoneal shunt,and the control group underwent ventriculo peritoneal shunt.The one-time success rates of two groups of patients were compared,and after a period of 6 months of follow-up,the incidences of postoperative complications were also compared through the patients′ clinical signs to determine the treatment effect.Results The rates of excessive or insufficient drainage tube blockage and the proportion of infected patients in the experimental group were significantly lower than in the control group (P<0.05),in addition,the total success rates of the patients in the experimental group were significantly higher than the control (P<0.05).Conclusion Compared with ventriculo peritoneal shunt,lumbar shunt has higher one-time success rate,at the same time,it could improve curative effect by reducing the occurrence of postoperative complications,which is worthy to be popularized.

目的：探讨脑-硬脑膜-动脉血管融通术（EDAS）联合颞浅动脉-大脑中动脉（STA-MCA）分支吻合术治疗低皮质微血管密度成人烟雾病（M M D）的疗效。方法：2011年1月至2014年6月58例低皮质微血管密度M M D患者，根据手术治疗方法分为对照组28例和观察组30例。对照组行EDAS，观察组行EDAS联合STA-MCA治疗。比较2组术前和术后颞浅动脉的平均流速（STA Vm）及搏动指数（STA PI）、改良Rankin评分（mRS）、局部脑血管流灌注率和改善率。结果：术后观察组STA Vm显著高于对照组（P<0.05），STA PI显著低于对照组（P<0.05）；Ⅱ和Ⅲ级重建率为56.67%，显著高于对照组的35.71%（P<0.05）；局部脑血管流改善率显著高于对照组（P<0.05）；m R S评分为（1.68±0.52），显著低于对照组（2.42±0.75）（P<0.05）。结论：EDAS联合STA-MCA能显著改善成人MMD患者血流状况和血管重建情况，提高患者生活质量，综合效果优于单独EDAS术治疗。

Objective To discuss the clinical characteristic ,diagnosis and treatment of acute hydrocephalus after aneurys-mal subarachnoid hemorrhage. Methods From February 2008 to September 2012 in our hospital ,48 cases with after acute hy-drocephalus after aneurysmal subarachnoid hemorrhage were selected to study. They were scanned by CT ,the clinical features of them were analyzed ,and they were treated by brain outdoor drainage treatment. After treatment ,they were investigated.Results After treatment ,the clinical status of 38 cases were obviously improved ,and of 10 cases got cured. The cerebral ven-tricle status under CT scan :41 cases got normal ,3 cases obviously deflated ,4 cases deflated a little. After 6 months of treat-ment ,the cases were followed up ,45 cases got clinical cured ,3 cases got recured and finally got clinical cured. Conclusion CT examination is a reliable means for diagnosis of acute hydrocephalus after aneurysmal subarachnoid hemorrhage ,and ventricular drainage can significantly improve their symptoms and improve the patient's cure rate. It is worthy of clinical application.

Objective To investigate the anatomy of the internal carotid artery and to provide the anatomical data for the microsurgical treatment of cavernous fistula. Methods A total of 12 cases of formalin fixed cadaveric head specimens( a total of 24 sides under the microscope) whose bilateral internal carotid artery and vertebral artery were already marked by the red latex perfusion for the observation and measurement of all segments of the intracranial arteries branches and the structure of the adjacent tissues. Seldinger technology and intervention embolization were performed in all 50 patients. Results Cavernous segment in the horizontal plane presented a S-shape bend. Meninges pituitary stem,cavernous sinus artery and McConnell backpack artery were the three main branches. A total of 50 patients with carotid cavernous fistula caused by trauma were cured by intervention embolization,and no recurrence occurred during the follow-up of 1. 5 years. Conclusion The internal artery is complex in anatomy and the trauma is the primary cause for the carotid cavernous fistula. The treatment of intracranial aneurysms and cavernous fistula via internal carotid artery approach is a new and effective microsurgical technique with less injury,more effectiveness and good recovery.
