食管型颈椎病数字化X线吞咽造影录像研究

目的探讨颈椎病所致吞咽障碍患者的数字化X线吞咽造影录像表现，并评定其应用价值。方法对175例颈椎病性吞咽障碍患者行数字化X线造影录像检查，应用图像后处理软件对录像逐帧分析，计数颈椎增生以及咽、食管后壁压迹的位置、数量，测量压迹宽度、深度。结果175例患者椎体前缘唇样、鸟嘴样增生396处，共出现压迹331个，其中单一压迹82例（46.5%），两处压迹30例（17.2%），三处压迹63例(36.3%)；压迹位于C3/4椎间隙9个(2.7%)、C4/5椎间隙78个(23.6%)，C5/6椎间隙154个(46.5%)、C6/7椎间隙81个(24.5%)，C7/T1椎间隙9个(2.7%)；其中轻度压迹216个（65.2%），中度压迹75个(22.6%)，重度压迹40个(12.2%)。结论数字化X线吞咽造影录像能够直观、精确、详细的分析颈椎病所致吞咽障碍患者颈椎骨质的改变以及咽、食管后壁受压情况，有重要的应用价值。

Digital X -ray video of swallowing angiography in esophago-cervical spondylosis

Objective To evaluate digital X -ray video of swallowing angiography in patients with dysphagia caused by cervical spondylosis. Methods 175 patients with cervical spondylotic dysphagia were examined with digital X-ray swallowing video, and then the video was analyzed frame-by-frame to count the number and location of hyperplasias of the cervical vertebra, and the width and depth of the impressions in the pharynx or esophageal posterior walls. Results In the 175 patients, 396 lip-like or beak-like hyperplasias were found in anterior edges of vertebral bodies, and 331 impressions were found in the pharynx or esophageal posterior walls. One impression was found in each of 82 cases (46.5%), two impressions were found in each of 30 cases (17.2%), and three impressions were found in each of 63 cases (36.3 % ) . Impressions at C3/4, C4/5, C5/6, C6/7 and C7/ T1 intervertebral space levels accounted for 9(2.7%), 78(23.6%), 154(46.5%), 81(24.5%), and 9(2.7%) respectively. Mild, moderate and severe impressions accounted for 216(65.2%), 75(22.6%), and 40(12.2%) respectively. Conclusion Digital X-ray video of swallowing angiography is intuitive, accurate and detailed to analyze the cervical vertebra changes in bones and compression situation of the pharynx or esophageal walls in patients with dysphagia caused by cervical spondylosis.
