Understanding Chronic Venous Insufficiency

Oct 10, 2023


Chronic venous insufficiency (CVI) is a common condition that affects millions of people worldwide. It occurs when the veins in the legs and feet fail to efficiently return blood back to the heart. Understanding the causes of CVI is crucial for effective diagnosis and treatment.

What Causes Chronic Venous Insufficiency?

Chronic venous insufficiency can be caused by various factors, each contributing to the impaired functioning of the veins. Let's explore some of the key causes:

1. Venous Valve Dysfunction

The most common cause of chronic venous insufficiency is the dysfunction of the venous valves. These valves prevent blood from flowing backwards, ensuring a one-way flow towards the heart. When these valves become weakened or damaged, blood can pool in the veins, leading to CVI.

2. Deep Vein Thrombosis (DVT)

Another potential cause of CVI is deep vein thrombosis (DVT). DVT is a blood clot that forms in the deep veins of the legs or pelvis. If left untreated, the clot can obstruct blood flow, causing long-term damage to the veins and leading to chronic venous insufficiency.

3. Obesity

Obesity is a significant risk factor for developing chronic venous insufficiency. Excess weight puts increased pressure on the veins, making it harder for blood to flow back to the heart. This can weaken the veins over time and contribute to the development of CVI.

4. Prolonged Sitting or Standing

Individuals who spend long periods sitting or standing are more susceptible to chronic venous insufficiency. Lack of movement can hinder healthy blood circulation and strain the veins, leading to valve dysfunction and the onset of CVI.

5. Pregnancy

Pregnancy can also increase the risk of developing chronic venous insufficiency. Hormonal changes and the growing uterus exert pressure on the veins, impairing blood flow and potentially leading to CVI.

6. Age and Genetics

Age plays a significant role in the development of chronic venous insufficiency. As we age, our veins naturally lose elasticity and become more prone to valve dysfunction. Additionally, some individuals may inherit a genetic predisposition to weakened veins, further increasing the likelihood of developing CVI.

Diagnosis and Treatment

Proper diagnosis and treatment for chronic venous insufficiency are essential to alleviate symptoms and prevent complications. At Vein Center of Arizona, our highly skilled team of doctors specializing in vascular medicine adopts a comprehensive approach to address CVI.

1. Duplex Ultrasound

Upon visiting our practice, our doctors may perform a duplex ultrasound, a non-invasive imaging test that allows visualization of the veins and evaluates blood flow. This helps identify any underlying issues contributing to CVI.

2. Compression Therapy

Compression therapy is a commonly recommended treatment for chronic venous insufficiency. It involves wearing specially designed stockings that apply gentle pressure on the legs, promoting better blood flow and reducing swelling.

3. Sclerotherapy

Sclerotherapy is a minimally invasive procedure that involves injecting a solution into the affected veins to cause them to collapse and eventually fade away. It is an effective treatment for both cosmetic improvement and reducing symptoms associated with CVI.

4. Endovenous Laser Ablation

Endovenous laser ablation is a state-of-the-art procedure that utilizes laser energy to treat damaged veins. It safely and effectively closes off problematic veins, redirecting blood flow to healthier ones and relieving symptoms of CVI.

5. Lifestyle Modifications

Alongside medical treatments, making certain lifestyle modifications can greatly contribute to managing chronic venous insufficiency. Regular exercise, maintaining a healthy weight, avoiding prolonged sitting or standing, and elevating the legs can all improve symptoms and prevent further complications.


Chronic venous insufficiency is a widespread condition with several potential causes. Understanding these causes is vital for effective diagnosis and treatment. At Vein Center of Arizona, our team of experienced doctors specializing in vascular medicine is dedicated to providing top-quality care to patients suffering from CVI. Through advanced diagnostic techniques and a comprehensive range of treatment options, we aim to improve the lives of individuals affected by chronic venous insufficiency.
