Comparative histopathological study of the venous wall of chronic venous insufficiency and varicose disease

Abstract

Objectivew To investigate venous histopathology of chronic venous insufficiency and varicose patients (C2). Methods Retrospective review of venous histopathology of 52 patients (13, 8, 2, and 28 were C2, C4, C5 and C6). Results The intimal thickness, intimal fibrosis, total thickness and intimal/total thickness ratio were highest in venous clinical severity score 0, 1 chronic venous insufficiency (no or minimal varicosity) follow by Venous Clinical Severity Score 2,3 chronic venous insufficiency (trunkal varice) and C2 veins (mean intimal thickness 62, 36, 26 µm, mean intimal fibrosis 74%, 72%, 65%, mean total thickness 184, 159, 133 µm, mean intimal/total thickness ratio 0.32, 0.20, 0.21). The statistical significances were found when comparing intimal thickness, intimal fibrosis, intimal/total thickness ratio and total thickness of Venous Clinical Severity Score 0, 1 chronic venous insufficiency veins and C2 veins. The medial changes are relatively constant among groups. Conclusion Compared with C2 vein, the intimal changes in chronic venous insufficiency venous wall differ, particularly in the VCSS 0, 1 chronic venous insufficiency.
