Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins , a treatable condition. [ 2 ]
CHIVA method is a type of surgery used to treat varicose veins that occur as a result of long term venous insufficiency. [1] The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency).
A common indicator for the prescription of such stockings is chronic peripheral venous insufficiency, caused by incompetent perforator veins. Low-pressure compression stockings are available without prescription in most countries, and may be purchased at a pharmacy or medical supply store.
[1] [2] [3] The use of this technique in wound management started in the 1990s and this technique is often recommended for treatment of a range of wounds including dehisced surgical wounds, closed surgical wounds, open abdominal wounds, open fractures, pressure injuries or pressure ulcers, diabetic foot ulcers, venous insufficiency ulcers, some ...
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 ...
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 management of lipodermatosclerosis may include treating venous insufficiency with leg elevation and elastic compression stockings. [9] In some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibrinolytic agents use an enzymatic action to help dissolve blood clots.
With the patient in the supine position, the leg is flexed at the hip and raised above heart level. The veins will empty due to gravity or with the assistance of the examiner's hand squeezing blood towards the heart.
