| 目的 探讨直窦近端解剖形态的CT血管成像表现与慢性脑积水的相关性。方法 30例慢性脑积水患者及50名正常人接受头部CT及头颈部CT血管造影(CTA)检查。对比观察慢性脑积水患者与正常人直窦近端影像,比较二者直窦顶、下矢状窦及大脑大静脉汇入直窦处形态,以及大脑大静脉及下矢状窦的长度、汇入直窦处的管径。结果 ①慢性脑积水患者直窦顶、下矢状窦形态显示与正常人无差异,大脑大静脉汇入直窦I型明显高于正常人。②慢性脑积水患者大脑大静脉及下矢状窦的长度及汇入直窦处管径与正常人相比明显减小。结论 利用CT血管成像技术观察直窦近端大脑大静脉及下矢状窦的长度和管径大小,对慢性脑积水的临床诊断具有指导意义。 |

| Objective To explore the dependability between the morphologic features of the proximal strait sinus and chronic hydrocephalus with CT angiography (CTA). Methods Thirty patients with chronic hydrocephalus (chronic hydrocephalus group) and 50 normal subjects (normal group) underwent cephalocervical CTA and cephalic CT scanning. Anatomic characteristics of the proximal straight sinus images, including its confluence site with the great cerebral vein, the top of straight sinus, and the inferior sagittal sinus were compared between chronic hydrocephalus group and normal group. Results ①The morphous of the straight sinus top and the inferior sagittal sinus in chronic hydrocephalus group were not different from the normal group, and the great cerebral vein abouchement sinus rectus type Ⅰ was more than normal group obviously. ②Compared to normal group,the great cerebral vein, the inferior sagittal sinus length and the abouchement caliber were obviously less in chronic hydrocephalus group. Conclusion Measuring the length and the caliber of the straight sinus proximal, the great cerebral vein and the inferior sagittal sinus with CT imaging technology is meaningful to the clinical diagnosis. |
