| Catheter | |
| Used during EVLT, a thin long tube designed to move within the vein, and close it by delivering laser energy. |
|
| Duplex scan |
|
| Ultrasound system that uses color to indicate the direction of blood flow.This is particularly helpful in visualizing and evaluating both the deep and superficial venous systems. |
|
| Compression therapy |
|
| A non-surgical therapy for venous insufficiency. Often involves compression stockings with varying degrees of pressure to improve blood flow and reduce symptoms caused by venous insufficiency. | |
| Deep veins | |
| Non-surface veins in the leg, which are near to the leg bones.They return blood directly to the heart. | |
| Deep vein thrombosis (DVT) | |
| Thrombus or blood clot, within a deep vein. | |
| Doppler | |
| Ultrasound device to detect the presence and movement of blood inside vessels. | |
| Endovenous |
|
| Inside a vein. | |
| Endovascular |
|
| Inside a blood vessel. | |
| Incompetent Vessel - | |
| Blood vessel that allows blood to fall back under the effect of gravity. | |
| Lumen | |
| Interior of a blood vessel. | |
| Edema | |
| Swelling caused by fluid. Frequently occurs in the legs and ankles of people with varicose veins. | |
| Paraesthesia | |
| Numbness or tingling often associated with damage to sensory nerves. | |
| Perforator veins | |
| Veins connecting the superficial veins and deep veins. | |
| Radiofrequency ablation | |
| A minimally invasive technique which closes the great or small saphenous vein using microwave energy delivered through a fine catheter.This interrupts the feed to the visible varicose veins avoiding open surgery and allowing a quicker recovery. |
|
| Reflux | |
| Reflux contributes to the development of varicose veins when incompetent leg vein valves let blood flow towards the feet instead of the heart. | |
| Saphenous vein - | |
| The long saphenous vein is a large vein running from the ankle to the groin; the short saphenous vein runs up the back of the leg from the ankle to the knee. |
|
| Sclerotherapy | |
| The injection of unwanted veins with a chemical. Often used for treatment of small diameter (1-2 mm) surface veins, such as thread veins. | |
| Superficial veins | |
| Veins just beneath the skin. Because they enjoy less support from nearby muscles and bones, they can develop areas of weakness in their walls and are more likely to become varicose than deep veins. | |
| Ulcer (venous) | |
| Lesion on skin caused by tissue loss (in the presence or caused by varicose veins). Valves- Flaps in the leg veins that open and close to prevent blood from flowing backwards. |
