摘要
目的探讨神经内镜下三脑室底造瘘术治疗交通性脑积水的磁共振特点,指导临床选择手术适应证。方法15例患者行神经内镜下三脑室底造瘘术,磁共振常规扫描分析其术前术后的影像特点。结果15例患者术后随访6个月至2年,术后影像显示梗阻部位的积水解除,脑室缩小,室周水肿现象减退,病人症状改善。结论磁共振可通过显示脑池的大小,三脑室底的形态,室周水肿现象推断交通性脑积水在脑室外脑池内梗阻部位,通过对交通性脑积水的术前影像分析,可帮助确定交通性脑积水行神经内镜下三脑室底造瘘术的手术适应证。
Objective To study the MRI characters of communicating hydrocephalus and analyze the indication of endoscopic 3rd ventrieulostomy. Methods Fifteen patients with communicating hydrocephalus treated by endoscopic 3rd ventrieulostomy were analyzed. The imaging characters of routine MRI scan were studied pre and postoperatively, respec- tively. Results Patients were followed between 6 months and two years, the MRI postoperatively showed that hydrocephalus was improved and enlarged ventricles as well as peri-ventricular edema were reduced. Conclusions MRI can show the shape of cisterns, three ventricular floor and the edema around the ventricle, therefore being able to analyze the extravent- ricular intracisternal obstructive site of communicating hydrocephalus. The imaging analysis of communication hydrocephalus preoperatively can help surgeon define the appropriate indication of communicating hydrocephalus treated by endoscopic 3rd ventriculostomy can identified through
