【摘要】：目的应用多层螺旋CT血管成像(MSCTA)探讨寰椎沟桥的涵义、分型及其对椎动脉影响。方法对头颈部MSCTA检查发现的92例沟桥原始数据采用VRT技术重建,观察沟桥的表现及其与椎动脉的关系。结果本组92例沟桥(133侧)中,单侧51例,双侧41例;单纯沟桥112侧,复合桥21侧;单纯沟桥中,后桥(PP)、侧桥(PL)、边桥(PB)的检出率分别为68.75%(77/112)、19.64%(22/112)、11.61%(13/112),而半环型(HR)、断环型(DR)、全环型(WR)的检出率分别为51.79%(58/112)、25.89%(29/112)、22.32%(25/112)。对椎动脉造成影响23侧,其中受压变形15侧、长期痉挛性狭窄8侧、受激惹痉挛4侧、椎动脉走行异常3侧,部分为多种影响同时发生。结论应用MSCTA可观察沟桥形态及其对椎动脉的影响,有助于对沟桥的临床意义进行研究探讨。
[Abstract]:Objective to investigate the meaning, classification and effect of atlas sulcus bridge by multislice spiral CT angiography (MSCTA). Methods the original data of 92 cases of sulcus bridge were reconstructed by VRT technique. The manifestation of the bridge and its relationship with vertebral artery were observed. Results among the 92 cases, 51 were unilateral, 41 were bilateral, 112 were pure sulcus bridge, 21 were composite bridge, and 51 were single sulcus bridge. The detection rates of PPV, PLP, PBB were 68.75, respectively. The detection rates were 77 / 112 / 19.64 / 22 / 112 / 11.61 / 112, while the detection rates of semicyclic HRT, Ring-type DRN, WRR were 51.79 ~ 5811 / 12, 25.89 ~ 25.89 / 29 / 12 ~ 22.32 / 25 / 112 / 12, respectively51.79 ~ 5811 / 12 ~ 25.89 ~ (25 / 32) ~ 22.32 / 112a / m ~ (25 / 12) / m ~ (25 / 12), respectively51.79 ~ 5811 ~ (12) and 25.89% ~ 25.89% ~ 22.32% ~ 22.32% ~ (12 / 12), respectively. 23 sides of vertebral artery were affected, including 15 sides of compression deformation, 8 sides of long-term spastic stenosis, 4 sides of irritated spasm, 3 sides of abnormal running of vertebral artery, some of which occurred at the same time. Conclusion MSCTA can observe the shape of sulcus bridge and its influence on vertebral artery, which is helpful to study the clinical significance of sulcus bridge.
