Veins are thin walled vessels through which impure blood is carried back to the heart. Varicose veins are a condition in which veins become enlarged, dilated or thickened. Affect more than 10% of the population
Varicose Veins & Venous Disorders
Aneurysms can form in arteries throughout the body, but most occur in the aorta. Starting in the heart and continuing through the chest and abdomen to the legs, the aorta is the body’s largest blood vessel. If the aneurysm occurs in the lower section of the abdomen, it is known as an abdominal aortic aneurysm (AAA) lower portion of the chest, it is called a thoracic aortic aneurysm (TAA). Involves aorta of chest and abdomen, it is known as thoraco-abdominal aortic aneurysm(TAAA) Likewise name of the aneurysm varies depending upon the blood vessel it affects
- Twisted cords, and usually appear on the calves, inside of the legs, and ankles.
- Usually no pain
- Aching, throbbing, cramping of the calf/leg
- Fatigue of the leg on long-standing
- Swelling of the leg
- Sudden pain may indicate clotting of blood in the vein
- Skin changes- darkening of the skin, dry skin, itching, contraction of skin
- Sudden bleeding from a long-standing vein
- Wounds in the leg(Venous ulcer) – non-healing, recurrent ulcers persisting in spite of long term dressing and surgical treatment
CAUSES OF VARICOSE VEINS
Can affect nearly anyone Underlying cause- valve dysfunctions
RISKS FACTORS OF VARICOSE VEINS
- Older age
- Family history of varicose veins
- Lack of physical activity
- Excessive sun exposure
- Previous DVT
- Narrowing of veins higher up (Pelvis)
DIAGNOSING VARICOSE VEINS
Confirms the presence of varicosities and its associated skin disorders
Minimal baseline examination to confirm the severity of varicose veins
to assess the deep veins not accessible by clinical examination access functional status of the veins
Rarely used only for unusual causes or if clinical picture and doppler ultrasound do not match
TREATMENT OF VARICOSE VEINS
Several treatment options are available
General measures- Losing weight, keeping the legs elevated, and wearing appropriately measured medical compression stockings.
Low-grade varicose veins- conservative management – stockings and medications
High-grade varicose veins with skin changes and ulcers- Options include
- Ablation procedure(heat-based) – endovenous laser ablation(EVLA)
- Glue Ablation(non-heat based) – Venaseal
- Injecting a solution into the targeted veins
- Sclerosing solution irritates the vein lining and turns it into scar tissue.
- Multiple sessions needed
- Also used as additional treatment after Ablation procedures
- Also used primarily for recurrent varicose veins.
Laser Ablation Procedure
- Minimally Invasive Principle- procedure delivers Laser via a catheter to the vein, which shrinks in the heat and eventually closes.
- Anesthetic and a saline solution are also injected to numb the leg, squeeze blood from the vein and protect surrounding tissue.
- Ultrasound imaging is used to locate the treatment site, guide the catheter and confirm that the vein has been fully closed.
The VENASEALTM procedure- uses a medical adhesive to seal the vein.
The risks of blood clots, infections, and other complications are extremely low as is the probability of recurrence. Recovery is very fast
Vein Stripping and Vein Ligation- An incision is made over the varicose vein, the vein is tied off, and stripping (surgical removal of the varicose vessel) is done to remove large varicose veins from the body. Ambulatory phlebectomy- making small pricks and removing smaller damaged veins
Treatment of Venous Ulcer
- Combination of compression- 4 layer bandage or stockings, medications- to control infection
- Sclerotherapy- to block the small veins near the ulcer site
- Ablation procedure- Laser/Glue to block the main culprit vein causing the ulcer
Preventing Varicose Veins
No certain way to prevent varicose veins from developing. Lifestyle changes that can be made in order to reduce your risk of developing this condition include
- Exercising regularly
- Maintaining a healthy weight
- Elevating the legs
- Avoiding sitting or standing in one position for too long
Spider veins – small, thin blood vessels prominently visible beneath the skin.
They appear most commonly on the face or legs. Series of lines, tree branches or a spider- or web-like shape, with a red or blue color. Most cases – purely cosmetic concern. Uncomfortable symptoms such as aching, burning, swelling and cramping
Valve dysfunction- backup of blood in certain veins, which may occur when the valves in the veins cannot effectively keep blood from flowing backward as it moves up the legs.
- Blood vessels expand and become visible under the surface of the skin.
- Common in the legs -blood flow must work against gravity to travel back up to the heart.
- 30 – 50% of all adults over the age of 50
- Hormonal changes
- Obesity and more.
Treatment of Spider Veins
- Mild cases of spider veins -compression stockings to put pressure on the veins and promote normal blood flow
- Interventional treatment is mainly for the cosmetic appearance of the leg if other underlying causes are ruled out. Sclerotherapy- injecting a sclerosing solution into the affected veins, causing them to gradually disappear.
- Fewer side effects, less pain, and shorter recovery times than traditional surgical vein removal.
- Additional treatment -endovenous radio-frequency ablation (EVRFA) or endovenous laser ablation(EVLA) which treats large veins by passing a heating fiber through a catheter directly into the vein.
Preventing Spider Veins
Life modifications – losing weight, exercising regularly, wearing support hoses, and wearing comfortable, flat shoes. It is important to move the legs frequently, especially if your job requires long periods of sitting or standing in one place.
