PURPOSE
Evaluation of MR imaging and CSF flow measurement for planning and follow-up of neuroendoscopic third ventriculostomy in occlusive triventricular hydrocephalus.
METHOD
17 patients with occlusive hydrocephalus due to idiopathic or neoplastic aqueductal stenosis were examined before and after surgery with cardiac-gated T2-weighted and cardiac-gated phase contrast cine sequences. The visibility of anatomic structures and the patency of the ventriculostomy were evaluated.
RESULTS
In all 17 patients, the relevant anatomic structures were visible. The cine sequence demonstrated occlusion of the aqueduct and patency of the ventriculostomy in all cases, even in patients with doubtful clinical patterns.
CONCLUSIONS
MR imaging with additional cardiac-gated cine sequences allows exact preoperative diagnosis of occlusive hydrocephalus as well as patient selection and planning for endoscopic third ventriculostomy. Non-invasive follow-up, especially in patients with a doubtful clinical pattern, is possible.
目的
评估磁共振成像（MR）及脑脊液（CSF）流量测量在梗阻性三脑室积水神经内镜下第三脑室造瘘术的术前规划及随访中的应用价值。
方法
对17例因特发性或肿瘤性导水管狭窄导致梗阻性脑积水的患者，在手术前后采用心电门控T2加权成像及心电门控相位对比电影序列进行检查。评估解剖结构的可视性及造瘘口的通畅情况。
结果
17例患者中，所有相关解剖结构均清晰可见。电影序列显示，所有病例中导水管均存在梗阻，而造瘘口均通畅，即使是临床症状不明确的患者也是如此。
结论
采用附加心电门控电影序列的MR成像能够对梗阻性脑积水进行准确的术前诊断，同时有助于患者的选择及内镜下第三脑室造瘘术的规划。无创性随访是可行的，尤其是对于临床症状不明确的患者。
