Chronic Venous insufficiency (CVI) is a progressive medical condition that worsens over time and affects the veins and vessels in the leg that carry oxygen-poor blood back toward the heart. Varicose veins, which are enlarged veins in the leg that appear due to the increase in venous pressure due to the malfunction of the venous system.
There are two types of venous insufficiency primary and secondary. Primary venous insufficiency is due to the lack of valves in the venous system. Secondary venous insufficiency is due to damage of the valves by previous thrombus, environmental factors that cause increased venous pressure and/or due to heredity. Approximately 80 million adults between the ages of 35 and 75 have chronic venous insufficiency.
Endovenous thermal ablation is a minimally invasive treatment that involves the insertion of a small thing, flexible tube called a catheter into a diseased vein to seal it shut using either a laser or radiofrequency to generate heat. Blood that would normally return to toward the heart through these veins will then travel through other veins instead. Over time the treated veins shrinks and is absorbed by the body.
The treatement is effective as the treated vein is the source of the venous insufficiency. Compared with surgical options like ligation and vein stripping, endovenous ablation results in less pain and quicker recovery time.
