Abstract:
Objective To discuss the aberrant right subclavian artery in CT,X-ray imaging manifestations and clinical meanings. Methods Analyzed 34 aberrant right subclavian artery cases' imaging features retrospectively and explicitly understand the clinical datas.At the same time,analyzed clinical meanings based on the documents. Results 8 cases in X-ray barium meal examination,6 cases showed that esophagus at aortic arch margo superior in back-front and oblique directions,runs a lower left to upper right spiral impressions,which was smooth,and the esophagus was locally cramped.CT in all 34 cases,in a single lay,aberrant subclavian artery was manifested as a soft-tissue nodule alongside or behind the esophagus,or a linear leaf,both connected to the aortic arch,and the density of them was equal to the vessels'.Continuous lays and rebuilded images show that aberrant right subclavian artery originates from the distal in-wall of aortic arch,and turns around the esophagus toward the upper right.It could impress the esophagus,but most of the patients had no symptoms.in a few esophagus and trachea seriously impressed cases,particularly in the aged,ocured the dysphagia and shortness of breath. Conclusion Aberrant right subclavian artery is easily found out in CT examina-toin,and observed the impression to the esophagus and trachea.in some cases,it also ocures in barium meal,but af-firmed by CT. To correctly understand the aberrant right subclavian artery 's imaging manifestions have a significant meanings in clinic.
