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 ]
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.

Acquired telangiectasia, not related to other venous abnormalities, for example on the face and trunk, can be caused by factors such as Cushing's syndrome; Rosacea; Blepharitis [9] Environmental damage such as that caused by sun [10] or cold exposure; Age [10] Trauma to skin such as contusions or surgical incisions.
Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
Vasculitis, peripheral arterial vascular disease, and lower extremity chronic venous insufficiency are the most frequent conditions to be taken into account during the differential diagnosis process. Peripheral artery diseases are diagnosed with the help of clinical signs, abnormal arterial Doppler ultrasound findings, and the ankle-brachial ...
This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage [7] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration.
Venous ulcer is defined by the American Venous Forum as "a full-thickness defect of skin, most frequently in the ankle region, that fails to heal spontaneously and is sustained by chronic venous disease, based on venous duplex ultrasound testing."
