  • Title: [The significance of disturbances of draining functions of the azygos vein in pathogenesis of varicose dilatation of the veins of the esophagus and stomach in portal hypertension (experimental-clinical investigation)].
    Author: Turmakhanov ST, Andreev GN, Borisova NA.
    Journal: Vestn Khir Im I I Grek; 2004; 163(4):17-20. PubMed ID: 15626067.
    Abstract:
    Under analysis were the results of investigations on 30 corpses, 25 dogs and of examinations of 187 patients with portal hypertension. In the experiments the disturbances of blood flow in the portal and azygos veins and the veins of the gastroesophageal basin were modeled. It was found that changes of the veins of the esophago-gastric area in diffuse lesions of the liver were already present even if there were no definitely detectable signs of portal hypertension. The experimental osseo-azygography has revealed dilatation of the azygos vein. The findings of examination of the patients admitted with esophago-gastric bleedings allowed detection of 5 degrees of impairments of blood flow along the azygos vein which increased risk of esophgeal-gastric bleedings.
