【摘要】 本文报道10例主动脉性咽下困难。病因为高血压和/或主动脉硬化。X线特征为:①下段食管不完全梗阻;②梗阻端正位呈两种不同形态:一为梳齿状;一为偏心性狭窄。左、右前斜位均为尖端指向前的偏心性狭窄;③受压移位食管左前斜位呈正“C”字形,右前斜位是反“C”字形,“C”字内有降主动脉断面致密影;④移位食管内之粘膜扭曲交叉。更多还原

【Abstract】 Ten cases of dysphagia aortica are reported. This kind of dysphagia is ca-used by hypertension and/or aortic sclerosis associated with elongation, tortuo-sity and dilatation of aorta as well as enlargement of left ventricle which co-mpress the lower segment of esophagus to produce incomplete obstruction ofesophagus. Its x-ray features consist of that:1) incomplete obstruction of eso-phagus; 2) in P-A view the stenotic end shows either a comb-toothed appea-rance or eccentric narrowing of the esophgeal lumen, while in RAO and LAOviews it shows an eccentric narrowing with the tapered end pointing forward;3) displacement of the compressed esophagus showing a "C" or reversed "C"shaped deformity and within the shadow of the "C"-curved esophagus one canfind the dense shadow of the descending aorta; 4) twisting of mucosal patternof the displaced segment of the esophagus更多还原
