椎动脉性眩晕的血管形态学变化及分型研究

目的：探讨椎动脉供血不足所致眩晕的血管形态学改变及分型。方法：对86例颈性眩晕患者，通过彩色经颅多普勒（TCD）检测有椎动脉血流速改变的82例，再作三维CT椎动脉血管造影（3D-CTA）检查，观察椎动脉形态学改变及其相邻组织的关系。结果：椎动脉形态学改变呈多样性，并与相邻组织的关系密切。结论：根据椎动脉形态学改变及与相邻组织的关系，可分为：增生压迫型、不规则狭窄型、阻塞型、纤细型、走行异常型及纤维束带牵拉型。

Study on vertebral artery morphological changes caused vertigo and its classification

Objective: To study the vascular morphological changes of vertigo and it s classification caused by ischemia of vertebral artery. Methods: 86 patients with vertigo caused by ische mia of vertebral artery were performed c olor transcrani al Doppler(TCD)detection and abnormal bl ood flow rates of vertebral artery were found in 82.Based on the examination res ults of tri-dimension CT angiography(3D- C TA)of vertebral artery and vertebral art ery morphological changes,the relation ship between vertebral artery and its n earby tissues was studied. Results: The morphological changes of vertebral a rtery were polymorphic and vertebral art ery had closed relationship to its near by tis sues.Conclusion: According to the results of the study ,vertebral artery caused vertigo can be classified follow types:hyperplasia and compression type,irregular narrow type,b lock type,slender type, abnormal alignme nt type and fibrous band drag type.
