Disease of the venous system

Statue of Ancient Rome Chronic venous insufficiency of lower extremity

anatomy Venous system of the legs is composed by two parallel and connected systems, the deep and superficial venous. These two systems was connected by perforating venous system

primary venous insufficiency etiological factor 1. Valvular incompetence →blood reflux→high pressure in venous→venous dilatation 2.Weak vessel wall→ dilatation→valvular incompetence

clinical manifestation Simple varicose venous—varicose of superficial vein , no complication complications— dystrophic complication in skins(eczema、ulcer) rupture to hemorrhage perforator venous insufficiency —ankle edema, dystrophic complication of ankle skins

Superficia varicose veins venous ulcer

diagnosis clinical manifestation imaging detection: phlebography color Dopple


Diagnostic studies Venography Forced Valsalva maneuver light region under valvula Normal valvula light region disappearing under valvula Valvula incompetence

treatment Conservative treatment: Compression Stockings or pressure bandages and lower extremity elevation Foam sclerotherapy Surgical treatment:high ligation and stripping of great (small) saphenous vein+varicose vein stripping deligation of perforating venous!
