Varicose veins are abnormally dilated tortuous veins in the legs.
SYMPTOMS OF VARICOSE VEINS
· Feeling of heaviness in legs
· Burning, sensation in legs
· Swelling in legs.
· Pain gets worsened after sitting or standing for a long time.
· Itching in legs
· Skin discoloration and ulcer formation.
CAUSE OF VARICOSE VEINS
Varicose veins are formed when there is :
1. Deep vein obstruction
2. Leg Muscle pump failure
3. Vein Valve failure
The commonest reason for varicose veins is valve failure which can result from inherited valve defects, hormones, trauma, previous history of thrombosis, or weakness of calf muscles.
Diagnosis and Treatment planning
The most effective diagnostic tool for varicose veins is a venous color, Doppler. Colour duplex ultrasound is a quick non-invasive test.
Treatment of varicose veins is done by an interventional radiologist. The treatment is minimally invasive with no surgical cut.
Interventional radiologists use three main methods of treatment. Endovenous laser (EVLT), Radiofrequency ablation, and foam sclerotherapy.
A small injection of local anesthesia will be given in the legs to numb the skin. A small sheath is inserted into the vein usually just below the knee. Using ultrasound guidance, the doctor then places a laser fiber or Radiofrequency ablation catheter through the sheath followed by injection of a local anesthetic around the vein along its length. The power is then turned on. After ablation, the sheath is withdrawn, a compression stocking will be applied.
What happens after your treatment?
Over the next few weeks after treatment, you may also get some bruising which is not problematic. You will be asked to come back for a follow-up after 4-6 weeks. You will be advised to wear compression stockings for two weeks after treatment.
