Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [ 1 ] The most common cause of CVI is superficial venous reflux which is a treatable condition. [ 2 ] As functional venous valves are required to provide for efficient blood return from the lower extremities, this ...
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.
Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term invented by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. [ 1 ][ 2 ] Zamboni hypothesized that it might play a role in the cause or development of multiple sclerosis (MS). [ 3 ][ 4 ] Zamboni ...
May–Thurner syndrome (MTS), also known as the iliac vein compression syndrome, [1] is a condition in which compression of the common venous outflow tract of the left lower extremity may cause discomfort, swelling, pain or iliofemoral deep vein thrombosis. Specifically, the problem is due to left common iliac vein compression by the overlying ...
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.

Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction. This practice is now less widely accepted. People with varicose veins should now be investigated using lower limbs venous ultrasonography.
