What is Venous Disease?

There are two main types of blood vessels in the body: arteries and veins. Arteries are the blood vessels that carry oxygen-rich blood from the heart to all parts of the body. In contrast, veins are the blood vessels that carry oxygen-poor blood from various parts of your body (organs and tissues) back to your heart. Venous disease is defined as conditions that impair the flow of blood from veins, especially those in the legs, to the heart due to the pooling of blood.

Causes of Venous Disease

Veins are hollow, flexible tubes with flaps inside called valves that open and close, directing the blood flow in one direction towards your heart. Venous disease occurs when these valves become weakened or damaged, causing blood to flow down in a retrograde (backward) fashion into the legs and pool in the veins. In simple terms, venous disease is a condition caused by malfunctioning of the valves in the veins of the legs.

Risk Factors for Venous Disease

Some of the risk factors that contribute to the venous disease include:

  • History of blood clots
  • Family history of venous disease
  • Obesity
  • Pregnancy
  • Prolonged periods of standing or sitting

Types of Venous Disease

Some of the common venous disorders include:

  • Varicose veins: These are large, dilated veins found just under the skin, typically in the legs, thighs, calves, and ankles.
  • Spider veins: These are clusters of dilated capillaries (the body’s smallest blood vessels) that appear red, purple, or blue in color and are typically visible on the legs and face.
  • Deep vein thrombosis (DVT): A condition in which a blood clot forms in the deep veins of the legs and thighs.
  • Pulmonary embolism (PE): A condition in which a blood clot typically from the legs breaks off and travels through the bloodstream and lodges in the veins of the lungs.
  • Phlebitis or superficial thrombophlebitis: An inflammation that causes a blood clot to form in a vein close to your skin’s surface that is red, swollen, and painful.
  • Chronic venous insufficiency: A long-term venous condition where blood pools in the leg veins due to impaired circulation causing severe swelling, sores, and other skin changes.

Signs and Symptoms of Venous Disease

Some of the signs and symptoms of venous disease include:

  • Pain or tenderness in the leg
  • Swelling of the leg
  • Increased warmth over the affected leg
  • Changes in the skin color
  • Fatigue
  • Heavy feeling in the legs
  • Slow healing leg sores
  • Twisted and bulged veins
  • Bleeding from damaged veins

Diagnosis of Venous Disease

Your doctor will diagnose venous disease based on a review of your medical history, physical examination, and test results. During the physical examination, your doctor will check your legs for swelling, tenderness, or skin discoloration. You may also undergo diagnostic tests, such as:

  • CT scan (computed tomography scan, also called CAT scan): An imaging technique that utilizes computer technology and X-rays to create cross-sectional and detailed pictures of the veins.
  • Duplex ultrasound: A non-invasive, painless test that shows how the blood is flowing through your blood vessels, the structure of the leg veins, as well as the degree of obstruction, if any, in your arteries.
  • Color-flow imaging: Also known as triplex ultrasound, this test is similar to a duplex ultrasound but utilizes color to show the direction of blood flow in veins.
  • Magnetic resonance venography (MRV): This test utilizes a combination of radiofrequencies, a large magnet, and a computer to produce more detailed images of the veins than a CT scan.

Treatment for Venous Disease

Depending on the condition and severity of your symptoms, your doctor may recommend the following conservative treatments:

  • Moving legs often and keeping yourself active
  • Wearing compression stockings to reduce swelling
  • Avoiding sitting or standing for long periods
  • Treating any infections and open wounds immediately
  • Losing weight in case you are overweight
  • Exercising regularly, which increases blood circulation to the legs
  • Avoiding tight clothes which may hinder circulation
  • Prescription medications to prevent and dissolve clots in your veins, as well as reduce swelling
  • Following a healthy diet high in fiber/a Mediterranean diet can help reduce a person’s risk of developing venous disease

In case you have a severe venous disease then your doctor may suggest the following minimally invasive or surgical treatments:

  • Ablation – This is the use of heat energy to close off the vein by destroying it, and the vein disappears gradually.
  • Sclerotherapy - The veins harden and then disappear when saltwater/saline is injected.
  • Vein stripping – Small surgical incisions are made to remove the damaged vein in the leg.
  • Valve repair – A small cut is made to repair the damaged vein valve in the leg.
  • Angioplasty and stenting – This procedure uses a small balloon to broaden the blocked vein and increase the blood flow. A metal mesh is used to prevent narrowing of the vein in the future.
  • Bypass – A surgery which is used to reroute the flow of blood around the damaged or blocked vein.
