Connection Between Varicose Veins and Deep Vein Thrombosis

Exploring the Connection Between Varicose Veins and Deep Vein Thrombosis (DVT)

Varicose veins and Deep Vein Thrombosis (DVT) are two distinct vascular conditions that often raise questions about their relationship.

Understanding the link between them, the differences, and the possibility of DVT causing varicose veins is essential for those concerned about their vascular health.

In this article, we will look into these aspects, shedding light on the expertise of an Interventional Radiologist, a specialist in varicose veins and deep vein thrombosis treatment, especially in the vibrant city of Mumbai.

Defining Varicose Veins and DVT

Before exploring the connection between varicose veins and DVT, it is crucial to understand each condition individually.

Varicose Veins: Varicose veins are swollen and twisted superficial system of veins that typically occur in the legs. 

Causes: These veins result from damaged or weakened valves in the veins. Normally, these valves keep blood flowing in one direction—towards the heart. When these valves weaken, blood can flow backward and pool in the veins, causing them to enlarge and become varicose.

Deep Vein Thrombosis (DVT): DVT, on the other hand, is a more serious condition. It involves the formation of a blood clot (thrombus) in one of the deep system of veins, most commonly in the legs.

DVT can lead to severe complications if left untreated, including the potential for a pulmonary thromboembolism (PTE). In PTE, clots can travel from deep veins in the legs towards the heart and lungs. If the clots are large enough, they maybe life-threatening.

Causes: DVT can occur when there’s a change in blood flow or blood composition, leading to clot formation. Prolonged periods of inactivity, surgery, trauma, or certain medical conditions can increase the risk of DVT.

What is the Connection Between Varicose Veins and DVT?

While varicose veins and DVT are distinct conditions, they share a common thread—the altered blood flow within veins.

Here’s How they are connected:

The venous system of the legs are interconnected. Usually the superficial veins will connect to the deeper veins at different levels.

The superficial veins will drain blood into the deeper veins. The deep system of veins will further carry this blood from the legs towards the heart.

Varicose veins primarily affect the superficial veins, while DVT typically occurs in the deep veins.

Varicose Veins as a Risk Factor for DVT: Having varicose veins can increase the risk of developing DVT. Varicose veins results in pooling of blood in veins. 

Stasis and Clot Formation: This pooled blood results in a state of stasis, where blood flow is slowed or stagnant in certain areas. This stagnant blood has increased the risk of clot formation, which may also involve the deeper veins leading to DVT.

DVT causing Varicose Veins: DVT can lead to damage of the valves of deep veins, making them inefficient and causing pooling of blood in deep veins over time. Also, DVT may affect the nearby superficial veins. These factors contribute to the development of varicose veins in patients with previous DVT.

Risk Factors and Commonalities:

Several risk factors are shared by both varicose veins and DVT. These include obesity, a sedentary lifestyle, smoking, and a family history of vascular conditions, clotting disorders.

Early detection and intervention are crucial steps to minimize the risk of complications.

Preventive Measures and Treatment

Preventing both varicose veins and DVT involves lifestyle changes and awareness.

Here are some key points:

  1. Lifestyle Changes: Maintain a healthy weight, stay physically active, avoid prolonged periods of sitting or standing, and stay hydrated.
  2. Compression Stockings: These can help improve blood flow and reduce the risk of clot formation in varicose veins.
  3. Medical Consultation: If you suspect you have varicose veins or DVT, consult an Interventional Radiologist for proper diagnosis and guidance on treatment options.

Seeking Professional Advice

If you have concerns about varicose veins, DVT, or their potential complications, it is essential to seek professional medical guidance. An Interventional Radiologist can provide a thorough assessment, diagnosis, and treatment plan tailored to your specific needs.

Varicose Veins Thrombosis Treatment in Mumbai

Effective treatments for varicose veins and deep vein thrombosis are crucial for preventing further complications. Dr. Amit Sahu is a renowned Interventional Radiologist & specialist in Vascular Health, offering advanced interventional treatment options in Mumbai.

Treatments for Varicose Veins include minimally invasive procedures like Endovenous Laser Treatment (EVLT), RadioFrequency Ablation (RFA), Venaseal or Sclerotherapy to close off and eliminate varicose veins.

For patients with DVT, Pulmonary ThromboEmbolism interventional treatments are performed to clear the clots inside the veins like Catheter Directed Thrombolysis (CDT) & Endovascular Thrombectomy.

Additionally, procedures like IVC filter placement is done in selected patients with DVT to prevent these clots from travelling towards the heart and causing life threatening pulmonary thromboembolism (PTE).


Understanding the connection between varicose veins and DVT is vital for maintaining good vascular health.

While they are separate conditions, the link between them underscores the importance of addressing varicose veins as a potential risk factor for DVT and vice versa.

If you have concerns about varicose veins, DVT, their potential complications or related treatments, do not hesitate to reach out to Dr. Amit Sahu, Interventional Radiologist, a leading specialist in varicose veins and deep vein thrombosis treatment in Mumbai.

He can offer expert guidance and advanced treatment options in Mumbai suitable to your individual needs.

Your vascular health is a priority, and seeking professional advice can make a significant difference in your well-being.
