Using duplex ultrasonography (US), the authors showed compression of the extracranial vertebral artery (ECVA) during neck rotation in 5.0% of 1,108 patients. Age (per 10-year increase, OR 0.80, 95% CI 0.67 to 0.96), vessel diameters (per 0.5-mm diameter increase, OR 0.63, 95% CI 0.51 to 0.79), and symptoms upon neck rotation (OR 4.01, 95% CI 1.35 to 11.9) were associated with vessel compression. In one case, SPECT revealed decreased cerebral perfusion of the hindbrain during rotation. ECVA US is useful in identifying vessel compression, especially in patients with symptoms on neck rotation.
作者通过双功超声检查（US）发现，在1108例患者中，有5.0%的患者在颈部旋转时出现颅外椎动脉（ECVA）受压。年龄（每增加10岁，比值比[OR]为0.80，95%置信区间[CI]为0.67至0.96）、血管直径（每增加0.5毫米直径，OR为0.63，95%CI为0.51至0.79）以及颈部旋转时的症状（OR为4.01，95%CI为1.35至11.9）与血管受压相关。在1例患者中，单光子发射计算机断层扫描（SPECT）显示旋转时后脑的脑灌注减少。ECVA超声检查有助于识别血管受压，尤其是在颈部旋转时有症状的患者中。
