Varicose Veins

Varicose veins

The cause of varicose veins remains unknown, but some believe that the problem lies in the wall of the vessels or the superficial veins, which are the veins that are located directly under the skin. 

This weakness may be hereditary, and over time this weakness may cause the veins to lose their elasticity, becoming longer and wider, resembling a snake under the skin.

Women may be more susceptible than men to this matter, and it may first appear during pregnancy or in cases who have risk factors for developing these varicose veins, such as obese patients and for long periods. 

Arteries transport oxygen-laden blood from cardiac to all parts of the body, veins return blood from the veins to the heart, and valves inside it maintain blood flow toward the heart and prevent backward flow.

Therefore, in people who have varicose vessel, the valves are ineffective and blood accumulates in the vessels, which leads to their enlargement, and this also leads to the formation of spider vessels, which are enlarged capillaries.

What are varicose veins caused by?

Varicose veins occur when they enlarge, expand and fill with blood, appearing through the skin swollen, prominent, bluesh-purple or red, and often painful.

It is a common condition that affects 25% of ladies and usually appears on the lower legs.

The veins contain a group of one-way valves, which prevents blood from flowing backward, but when these valves malfunction or something occurs in the veins, or if the walls of the vein become tight and inflexible, blood begins to accumulate in the veins and does not return to the heart again.

And may in a weakened valve, blood leaks backward or eventually flows in the opposite direction, resulting in enlarged or twisted of  varicose veins. 

Varicose vessels more usually appear in the legs because the leg are under a lot of compression to return blood to the heart.

There are many factors that increase the chances of developing varicose vessels, comprising:

  • Pregnancy.
  • Menopause.
  • Advanced aging (increased incidence over 50 years old).
  • Standing for long period.

Family history of varicose veins.

Varicose veins usually  appear at an early age as many factors, comprising:

  • Obesity: It is one of the most important reasons associated with the occurrence of varicose veins, as excess weight increases squeezes on them in the legs, the expansion of the wall of the veins and appear of varicose vessel  usually appear in surface.
  • Poor clothing choices: The quality of clothing might affect the healthy of the vessels greatly. Wearing excessively tight clothes or wearing high heels with movement or running might cause the wall of blood vessel to dilate, which over times might cause varicose vein usually  appear  in surface.
  • Stability in a certain position for a long period: standing for long period is of most important reasons of varicose veins, as well as sitting for long hours in the same position that lead to swollen veins and varicosity. 
  • Genetic: If the parents have varicosity, the possibility of their children being infected is great, and in this case it can be avoided by following healthy daily habits, and if varicose veins are hereditary, they usually  appear at a young aged, and it is necessary if varicose vein are widespread in the family.

Many ones with varicose veins have spider vein, which are twisted or enlarged capillaries.

What are types of varicose veins?

There are two types of them that impact the body, the most prominent of which are the following: 

  • The first type: that occurs suddenly without reasons or disease that led to it appearances, and is often associated with genetic factor related to the weakness of the interfacial tissue of the body, and includes that impact the testicles and anal hemorrhoids, in addition to hernias.

Flat feet, which increases the chance of developing this type of varicose (spider) veins is standing for long periods of time.

  • The second type: This occurs as a result of a previous disease, or occurs as a complication of other diseases, and includes that impact pregnant, legs and swollen pelvic areas. 

Can birth control cause varicose veins?

No, in general, contraceptive methods do not cause varicose veins in the feet, whether they are birth control pills or other methods.

What are symptoms of varicose veins?

In most cases of varicose vessel, the affected person does not feel pain or not experiencing any symptoms.

The veins usually appear twisted, swollen, and are blue.

Other symptoms that some cases with varicose in leg may feel comprise:

  • Leg pain.
  • Feeling that the legs are heavy from varicose vessel, especially after exercising or at night.
  • Bleeding continues for longer than usual when the area affected by the varicose vein suffers a slight injury.
  • Lipocutaneous sclerosis: The subcutaneous fat just above the withers can become hard causing the skin  surface of leg to shrink.
  • Telangiectasia in a leg affected by varicosity, and these dilated hairs are called spider veins.
  • Bright discoloration near twisted or enlarged  varicose vessel, usually bluish or brownish in color.
  • The appearance of venous eczema or the so-called stasis dermatitis, where the skin in the affected zone becomes red, dry and itchy.
  • Leg cramp occurs in some cases who suffer from enlarged  varicose vein of  leg when stand up suddenly.
  • Restless Leg  Syndrome occurs in a high percentage of cases who suffer from  twisted or enlarged  varicose veins.
  • The appearance of white, irregular, scar-like spots on the ankles, these spots are Atrophie Blanche.
  • Swollen ankle.

Does smoking cause varicose veins?

  • Effect on vein valve: Smoking can damaging  vessels and vein valve.  This damaging can increase the possibility of vein valve being ineffective in preventing fl9w from blocking in the wrong direction, which can contribute to dilated vessels and the appearance of varicose veins.
  • Effect on flowing: Smoking reduces flowing and causes constriction of vessels, which can lead to increase pressure inside the vessels and dilation.
  • Increase vascular inflammation: Smoking contributes to increase vascular inflammation, a factor that can lead to weakening and dilatation of vessel walls.
  • Effect on collagen and elastin: Smoking can damaging collagen and elastin, which play an important role in the strength of vessel walls.

How to diagnose varicose veins?

The surgeon usually examines the legs and visible vessel while the patient is standing or sitting to diagnose varicose veins in legs, and he also asks him about the presence of any symptoms or pain.

  • The physician also perform an ultrasound to check flowing.

This test is a non-invasive procedure that uses high-frequency sound waves and allows the physician to see how the flowing in the veins.

  • A venogram also be done to better evaluate the veins.

During this procedure, the physician injects a special dye into the patient’s legs and makes an x-ray of the zone.

The varicose veins of legs in which the dye was injected are shown through the x-rays, which helps the physician see better flow.

  • Ultrasound and venography help make sure that there is no other disorder (such as a clot or embolism) causing the ache in the legs.

What is varicose veins treatment?

In general, doctors advise when treating of enlarged varicose vessel to make lifestyle changes rather than trying treatments at first.

A wide range of options are available for enlarged varicose vessel, include:

  • Use of liquid or foam chemical injections to resolve varicose vessel.
  • Microsurgery system, using a liquid chemical injection to prevent narrowing of twisted or enlarged varicose veins
  • Laser therapy.
  • Venous ablation, using heat waves and radiofrequency waves to prevent vessel swell.
  • Laparoscopic vein therapy.

You should always talk to your doctor about treatment and risks before choosing an appropriate method, which depends on your symptoms and the size and location of enlarged varicose veins.

How to prevent varicose veins?

The following changes may help prevent varicose veins from getting worse and include:

  • Avoid standing for long period of.
  • Lose weight and maintain a healthy weight.
  • Exercising to improve circulation.
  • Use or wear compression stockings on the affected zone to reduce swelling.
  • Elevation of your legs when resting or when sleeping.
  • Surgical procedures enlarged varicose vessel.
  • If lifestylies changes don’t work, or if your varicose vessel are causing a lot of ache or harming your general health, your physician may try a surgical procedure, which is done by ligation and striping the vessel under anesthesia.

During vascular surgery, the surgeons cuts the affected vessel and removes it.

Through incisions, although vessel stripping surgeries has been developed, it is less common due to the lack of modern medical treatment.

Can varicose veins disappear on their own without surgeries?

Treatment of varicose veins may include a number of measures aimed at alleviating the severity of symptoms or limiting their development, including:

  • Wearing compression stockings as an initial treatment solution before resorting to other treatment , as pressure on the veins and muscles of the legs improves flow.
  • Sclerotherapy (injecting enlarged small and medium veins with a solution that stimulates scarring and blockage of it and its fading after several weeks).  
  • Laser treatment (exposing the enlarged vessel to laser rays to stimulate the gradual disappearance of the vessel) without the need to make any surgical incisions.  
  • Catheterization of the veins by inserting a thin tube whose tips raise the temperature to stimulate damage to the vessel and seal it. This procedure is performed for large enlarged leg veins.  
  • Exposing the veins by pulling the enlarged long veins through a small skin incision.  
  • Pulling small enlarged veins through microdermal puncture.  
  • Venoscopy surgeries in advanced cases of varicose veins in the legs to close the enlarged vessel.  “If it doesn’t work, you may have to have surgeries.”
