[Morphology and vascularization of the varicose internal saphenous vein. Comparison with the normal structure].
After reviewing the main characteristics of the normal long saphenous vein, the histological alterations observed in varicose veins are described. Samples were obtained from 14 patients undergoing venous surgery for varicose veins with long saphenous vein incompetence. These alterations mostly involve the connective tissue prolife-rating in the middle layer and causing the separation and interruption of the muscular bundles. In addition, the vasa vasorum network through the venous wall was investigated. These vessels were normally observed in the adventitial layer and the outer third of the media. In some samples from varicose veins, vasa vasorum were increased and capillaries close to the intimal layer.
