Question 1

How do varicose veins form?

Accepted Answer

The primary cause of varicose veins is due to weak or damaged valves in the veins, which cause the blood to flow backward and pool in the veins. This can be caused by genetics, age, pregnancy, and standing for long periods of time. Other contributing factors include lifestyle habits such as obesity or a lack of physical activity.

Question 2

What complications can arise from varicose veins?

Accepted Answer

Most patients with varicose are not at risk, though a small but significant number can go on to have significant complications. These include:

Acute superficial thrombophlebitis: This is due to a thrombosis (clot) in a varicose vein. The vein becomes hard, tender and inflamed, and may take several weeks to settle. Unlike a deep vein thrombosis, this is usually not dangerous and does not require anti-coagulation (blood thinners).

Bleeding: This is a very uncommon event, treatment involves compression of the bleeding point with a bandage, and elevation of the leg.

DVT: The incidence of Deep Vein Thrombosis (DVT) is exceedingly low (less than one in 500).

Swelling of the leg: This can occur due to faulty valves and high pressure in the veins.

Venous pigmentation and eczema: These are skin changes that reflect pressure in the veins. They are often an indication that treatment of the varicose veins and venous insufficiency is necessary.

Lipodermatosclerosis: This is hardening of the soft tissues of the lower leg, and again a reflection of exceedingly high venous pressures. This is a risk factor of ulceration.

Venous ulceration: This typically occurs in patients with signs of venous hypertension such as lipodermatosclerosis and venous eczema. It most often overlies the inner ankle (medial malleolus).

Haemosiderin Staining: Occasionally we see staining (a brown pigment) which has the appearance of a bruise and may take several months to disappear.

Question 3

Will my varicose veins come back after treatment?

Accepted Answer

While there is a possibility that varicose veins may recur after treatment (10-15%), taking proper care and following your doctor’s instructions can significantly reduce this risk. By making lifestyle changes and adopting healthy habits, you can promote the health of your veins and help maintain the positive effects of the treatment.

Question 4

When should varicose veins be treated?

Accepted Answer

Varicose veins can be successfully treated, especially if they cause significant discomfort or complications or if the appearance of the veins is a concern. With the right treatment, you can alleviate discomfort, improve the appearance of your legs, and prevent serious complications.
