What Are Varicose Veins?

Varicose veins are twisted and swollen veins that can appear anywhere on the body, although they most commonly appear in the legs. These veins usually cause mild symptoms, but if they’re left to progress, they can cause some serious and sometimes life-threatening symptoms. These veins develop as a result of a breakdown in the valves in the legs that carry blood from the legs to the heart, and vice versa. 


What are Blood Clots?

Blood clots are clusters of blood that are no longer liquid, but they’re gel-like or semi-solid. The blood clots as part of the healing process whenever an injury occurs. In some cases, blood clots can form inside veins, and once this happens, the clots are unable to dissolve on their own. Are blood clots dangerous? They can be depending on where they form. A serious complication of deep vein thrombosis (DVT) is pulmonary embolism. This can be life threatening and happens when a piece of the blood clot moves to your lungs. 

Are Varicose Veins a Warning Sign of Blood Clots?

In some of the more severe cases of varicose veins, blood clots can sometimes form inside the swollen veins. This is diagnosed as a condition called deep vein thrombosis, (DVT). However, varicose veins aren’t necessarily a warning sign of blood clots, although the symptoms of each condition are similar. Also, it has been discovered that individuals with varicose veins have a higher susceptibility to developing DVT.

Symptoms of Blood Clots

Symptoms of blood clots depend on where the clot is located. A blood clot that has formed in the brain is a type of stroke (thrombotic) and can cause several symptoms like severe headaches, reduced consciousness, stiffness in the neck, vomiting, and more. Understand the different types of stroke such as ischemic stroke when a blood clot (thrombus) occurs.  If the blood clot occurs in the lungs, then symptoms will include shortness of breath, chest pain, and coughing up blood. 

If a person develops a blood clot in the legs, they may notice the following symptoms:

  • Severe leg pain that doesn’t subside
  • Redness
  • Swelling

Types of Blood Clots

Superficial blood clots or phlebitis are blood clots that occur just underneath the skin. These types of clots don’t typically enter the bloodstream, though they can cause significant pain, which requires treatment. 

Deep vein thrombosis (DVT) is a potentially deadly clot condition that occurs in the primary veins of the legs, thighs, or pelvis. It’s also referred to as venous thrombosis, and these blood clots can become life-threatening if they become dislodged and travel to certain areas of the body. 

 A pulmonary embolism (PE) is what occurs when a DVT travels from the leg to the lung, where it can become trapped. PEs cause damage to the lungs and block blood flow, which can result in death if not treated promptly.

Risk Factors for Varicose Veins

Although anyone can develop varicose veins, some people with certain risk factors are more susceptible to them.  Some risk factors for varicose veins include:

Just like with varicose veins, anyone can develop blood clots, but some people are more likely to develop them than others. Some risk factors for blood clots are extended periods of sitting, hospitalization, obesity, pregnancy, heredity, and organ transplant, among others.

Minimally Invasive Procedures for Varicose Vein Treatment

Not all patients with varicose veins need open surgery, and there are some minimally invasive procedures to treat this condition. They include:

  • Conservative medical management including compression socks – Compression socks can effectively treat the earlier stages of varicose veins in some cases 
  • Laser endovenous treatment (EVLT) – When undergoing an EVLT, a heated laser is used to close off damaged veins and promote healing. Blood flow is redirected to other veins, as treated veins will no longer be functional.
  • Radiofrequency endovenous ablation (RFA) – This treatment involves the use of energy to cauterize damaged veins, and then scar tissue is formed
  • Venous avulsions – This procedure entails the removal of the damaged veins through tiny incisions.
  • Sclerotherapy – This therapy involves the injection of a special solution into the affected veins, which irritates the blood vessels and encourages healing and improvement in their appearance.
