bjective:Observation of the artery trend on the inferior thoracic and abdominal segment of the esophagus,especially for the cardiac sphincter region.Methods:The ramifications,length and diameter of the artery was measured on 15 adult cadaveric specimens perfused with red emulsion.Results:A esophageal artery,whose the mean diameter is 1.4±0.5 mm,was very common in the inferior thoracic segment.Most of the abdominal part was found to be supply by two arteries.The semicircled artery around the cardiac was 2.1±0.7 mm in diameter and 5.5±1.5 cm in length,3 to 8 small branches of them penetrated into cardiac spincteror anastomosed with the branches of inferior thoracic segment of esophagus.Conclusions:Compared with the blood supply of inferior thoracic esophageal segment,that in abdominal esophageal segment was more abundant.The semi-circled esophageal artery is closely related to the structure and function of cardiac spincter.
