The value of azygography in carcinoma of the esophagus
Surgery, Gynecology & Obstetrics
|August 1, 1975
Abstract:
A method of azygography has been used in a study of patients with carcinoma of the esophagus prior to thoracotomy. Total blockage or progressive reduction of venous caliber at the actual level of the lesion with contralateral filling of the azygos vein or back pressure signs on the azygogram indicates that the growth is not resectable at operation.
