C

Chronic Venous Insufficiency (CVI)

CVI occurs when leg veins can't efficiently return blood to the heart, leading to swelling, aching, and skin changes. It’s often a result of faulty valves in the veins.

D

Deep Vein Thrombosis (DVT)

DVT is the formation of a blood clot in a deep vein, typically in the legs. It can cause pain, swelling, and carries the risk of a life-threatening pulmonary embolism if left untreated.

L

Lymphoedema

Lymphoedema is swelling caused by a buildup of lymph fluid, often in the arms or legs. It can result from lymph node damage or removal, commonly after cancer treatment.

P

Pelvic Congestion Syndrome

This condition causes long-term pain in the lower stomach area (pelvis), often due to enlarged veins. It can feel worse after standing or during periods.

Post-Thrombotic Syndrome (PTS)

PTS develops after a DVT when vein valves get damaged. This makes it harder for blood to flow properly, leading to pain, swelling, and skin changes.

S

Spider Veins (Telangiectasia)

Spider veins are small, dilated blood vessels visible near the skin’s surface, often on the legs or face. They’re generally harmless but may cause cosmetic concern.

Superficial Thrombophlebitis

This is the inflammation of a vein near the surface of the skin, often with a small blood clot. It causes redness, warmth, and tenderness over the vein.

V

Varicose Veins

Varicose veins are enlarged, twisted veins, usually in the legs, caused by valve failure and poor blood flow. They can lead to aching, swelling, and cosmetic concerns for some.

Venous Leg Ulcers

These are chronic wounds on the lower legs caused by poor venous circulation. They are slow to heal and require comprehensive wound and vein care.
