Venous valves. The most common cause of chronic venous insufficiency is reflux of the venous valves of superficial veins. [2] This may in turn be caused by several conditions: Deep vein thrombosis (DVT), that is, blood clots in the deep veins. Chronic venous insufficiency caused by DVT may be described as postthrombotic syndrome. DVT triggers ...
Chronic venous insufficiency (CVI) is when the valves in the leg veins don’t work right and inappropriately allow blood to flow backward, back into the legs/feet from the effects of gravity.
Underlying causes include weak or damaged valves in the veins. [1] They are typically diagnosed by examination, including observation by ultrasound. [2] By contrast, spider veins affect the capillaries and are smaller. [1] [7] Treatment may involve lifestyle changes or medical procedures with the goal of improving symptoms and appearance. [1]
Venous insufficiency is the most common disorder of the venous system, and is usually manifested as either spider veins or varicose veins. Several treatments are available including endovenous thermal ablation (using radiofrequency or laser energy), vein stripping, ambulatory phlebectomy, foam sclerotherapy, laser, or compression.

The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency). The method is based on the assumption that the symptoms of varicose veins are mainly the expression of an hemodynamic circulatory disorder, induced by various venous system ...
Venous leak; Other names: Venogenic erectile dysfunction, penile venous insufficiency: Specialty: Andrology: Complications: Erectyle dysfunction: Causes: Chronic venous insufficiency, varicose veins, damaged vein walls from trauma, genetic causes: Treatment: Ligation of leaking veins, lifestyle changes: Frequency: Arterial insufficiency ...
The venous circulation going back to the heart, on the other hand, is a low-pressure system with a central venous pressure around 5mm Hg. This means that the movement of blood has to rely heavily on what’s called the skeletal muscle pump, which is just a way of saying that it relies on the contraction of surrounding skeletal muscles, which ...
Despite ongoing research, the cause of PTS is not entirely clear. Inflammation is thought to play a role [5] [6] as well as damage to the venous valves from the thrombus itself. This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries.
