Although superficial varicose veins of the lower extremities are not life-threatening, they can cause many unpleasant complications, affecting the patient's life and work. Surgery is the most widely used treatment for varicose veins in the lower extremities.1. Learn about superficial varicose veins of the lower extremities
1.1 Where does varicose veins occur? The veins of the lower extremities are divided into 3 systems as follows:
Superficial veins: Located under the skin, including 2 main groups: External saphenous veins (large, located on the inner surface of the thigh from ankle to inguinal fold) and saphenous veins medial (smaller, located from the outer ankle to the heel). Venous insufficiency usually occurs in the superficial veins; Deep Veins: Veins accompanying arteries, not dilated, only inflamed; Peripheral veins: Transport blood from the superficial veins to the deep veins. Chronic superficial venous insufficiency of the lower extremities is a condition in which the superficial veins are dilated, tortuous, prominently under the skin, and have a refluxed flow. Depending on the cause, morphology, varicose veins are divided into groups:
Primary varicose veins: Initially the veins are long, dilated, then lose function; Secondary varicose veins : The venous valves lose function, then the veins become elongated and dilated; Varicose veins in pregnancy: The veins are dilated due to the influence of hormones or the large uterus causes compression of the deep veins. After giving birth, varicose veins may go away on their own; Congenital varicose veins: Due to a defect in the venous valve.
1.2 Classification of superficial varicose veins of the lower extremities Grade 0: Only functional symptoms; Grade 1: Distal varicose veins, reticular, ankle swelling; Grade 2: Varicose veins; Grade 3: Edema but no signs of skin changes; Grade 4: Dull skin, eczema and scleroderma; Grade 5: Dark skin, eczema, scleroderma with healed ulcers; Grade 6: Dull skin, eczema, scleroderma and active ulceration. 1.3 Symptoms of superficial varicose veins in the lower extremities First stage: Swollen lower extremities, feeling of heaviness in the legs, leg pain, cramps at night. Symptoms of the disease will go away when resting or lying with the legs elevated; Later stage: There are patches of nutritional disorders on the skin, superficial veins under the skin are zigzag, there are episodes of phlebitis causing fever, infection, bleeding trophic ulcers. 1.4 Complications of superficial varicose veins of the lower extremities Blood flow disorders: Causes leg swelling, especially when standing a lot, pain in the back of the lower leg and cramps at night; Dystrophy of the legs: Eczema appears in the lower legs, skin color changes due to blood stasis in the veins for a long time, causing metabolic disorders; Venous bunions: Swollen veins cause heaviness, pain in the legs, blood escaping from the vessels causing leg edema, even visible swollen veins on the skin and bruises on the skin;
Leg ulcers: Initially, the ulcer can heal on its own, then the disease progresses, the ulcers do not heal on their own, but there is a risk of infection and the treatment is very complicated; Severe complications: Thrombophlebitis causes swollen, hot, red, painful legs, prominent superficial veins, hard inflammation. In the final stage, the entire venous system dilates, causing complete stagnation, leading to trophic ulcers, bleeding, and infection. Even blood clots that form in the veins can leave the veins and return to the heart, causing pulmonary embolism, leading to death. 1.5 Treatment of varicose veins of the lower extremities In the early stages, patients are often prescribed medical stockings to restore the pressure difference between the superficial and deep venous systems through the perforating veins. Then, depending on each case, the patient may be prescribed drugs to stabilize the vessel wall, anti-inflammatory; perform local sclerotherapy.
Where these methods are not effective, the patient is recommended to undergo surgical treatment, including Stripping surgery (removal of the entire varicose vein) or Chivas surgery (removal of small veins in place). or freeze the vein with liquid nitrogen. After surgery, patients should continue to take intravenous stabilizers.
