What is Chronic Venous Insufficiency?

Chronic venous insufficiency (CVI) is a common vascular disorder that affects millions globally. Also known as vein disease, CVI is characterized by improper functioning of leg veins, which hinders blood flow back to the heart, leading to blood pooling in the lower extremities. This condition is closely associated with varicose veins, spider veins, and other symptoms of vein disease. Understanding CVI's causes, symptoms, and treatment options is crucial for effective management and prevention.

According to ScienceDirect, 25 million Americans have varicose veins, with more than six million more afflicted with more advanced forms of chronic venous disease, including swelling, skin changes, and open ulcers that are slow to heal.

In this blog, you’ll learn about the symptoms, causes, prevention tips, and the latest outpatient treatment options for chronic venous insufficiency, designed to restore leg comfort and vein health.

Understanding Chronic Venous Insufficiency

In a healthy circulatory system, veins carry deoxygenated blood from various body parts back to the heart. Leg veins are lined with tiny one-way valves that prevent blood from flowing backward. In CVI, these valves become weakened or damaged, allowing blood to flow backward and pool in the legs, a condition known as venous reflux. Over time, this increased pressure can lead to swelling, pain, and visible varicose veins.

These symptoms can significantly impact your quality of life, but effective treatments are available to help manage the condition and improve circulation.

Key Points:

• Healthy Veins: One-way valves ensure upward blood flow toward the heart.
• Diseased Veins: Damaged vein valves allow blood to flow backward, causing pooling and increased venous pressure.

Vein Disease Prevalence and Risk Factors

Chronic venous insufficiency is a common condition, particularly among older adults, with the management of chronic venous insufficiency accounting for approximately two percent of the total healthcare spending in the United States.

According to the National Library of Medicine (NHI):

“An estimated 10 percent to 35 percent of adults have CVI in the US, with four percent of adults aged 65 years or older developing venous ulcers.”

Further, the condition is more prevalent among women:

“Results across studies suggest that in the general population, between one percent and 17 percent of men and one percent and 40 percent of women may experience chronic venous insufficiency.”

Several factors contribute to the development of CVI:

1. Age: The risk of CVI increases with age due to natural wear and tear on vein valves.
2. Gender: Women are more susceptible, possibly due to hormonal influences.
3. Family History: Genetics play a significant role; a family history of vein problems increases risk.
4. Obesity: Excess weight adds pressure to leg veins, exacerbating valve dysfunction.
5. Pregnancy: Increased blood volume and hormonal changes during pregnancy can weaken vein walls.
6. Prolonged Standing or Sitting: Occupations requiring extended periods of immobility can strain veins and valves.
7. Smoking: Toxins in cigarettes damage vein walls and reduce oxygen levels in the blood.

Wondering if you might have chronic venous insufficiency (CVI)? Taking a quick self-assessment can help identify common symptoms like leg pain, swelling, and varicose veins that may indicate vein disease. It’s a simple first step toward understanding your vein health and deciding if it’s time to consult a Center for Vein Restoration (CVR) vein specialist. CVR is America’s largest physician-led vein center.

Symptoms of Chronic Venous Insufficiency

CVI presents a range of symptoms that can vary in severity:

• Leg Pain: A heavy, aching sensation in the legs, often worsening with prolonged standing or sitting.
• Swelling (Edema): Notable in the ankles, feet, or legs, especially after extended periods of inactivity.
• Varicose Veins: Enlarged, twisted veins visible just beneath the skin's surface.
• Spider Veins: Smaller, web-like clusters of veins visible on the skin.
• Skin Changes: Discoloration, thickening, or the development of ulcers that are slow to heal.
• Restless Legs: An uncontrollable urge to move the legs, often accompanied by a crawling sensation.

Don’t let chronic venous insufficiency disrupt your life.

Complications Associated with Chronic Venous Insufficiency

Chronic Venous Insufficiency, if not managed appropriately, can lead to several complications:

Venous Ulcers: Open sores that develop on the skin, typically around the ankles, due to prolonged pressure and insufficient blood flow. The National Library of Medicine (NIH) estimates that approximately 2 million workdays per year are lost due to venous ulcer-related disability, and more than 12 percent of workers with venous ulcers retire prematurely as a result.

Venous ulcers are a financial burden on the healthcare system as a whole, with an estimated $1 billion spent annually in the United States on chronic wound treatment, according to the NIH.

• Superficial Thrombophlebitis: Inflammation of veins just under the skin, often accompanied by a blood clot.
• Deep Vein Thrombosis (DVT): Formation of a blood clot in a deep vein, which can be life-threatening if it travels to the lungs, causing a pulmonary embolism.

Diagnosing Chronic Venous Insufficiency

Early diagnosis is vital for effective treatment. A CVR vein specialist, also known as a phlebologist, will conduct a comprehensive evaluation, which may include:

1. Physical Examination: Assessment of visible signs such as varicose veins, skin changes, and swelling.
2. Medical History: Discuss symptoms, lifestyle factors, and family history.
3. Duplex Ultrasound is a noninvasive test that uses sound waves to visualize blood flow and detect valve dysfunction or blood clots.
4. Venography: In certain cases, a contrast dye is injected to provide detailed images of vein structures.

Accurate diagnosis ensures that appropriate treatment plans are developed, addressing both superficial symptoms and underlying venous issues.

Treatment Options for Chronic Venous Insufficiency

Research reported by the National Center for Biotechnology Information (NIH) confirms that minimally invasive procedures have transformed vein care, offering higher success rates and faster recovery than traditional surgery. Focusing on success rates, recurrence, cost-effectiveness, safety, and patient satisfaction, the study emphasizes the positive impact these office-based procedures have on quality of life.

Minimally Invasive Treatment options include:

• Sclerotherapy: Injection of a solution into affected veins, causing them to collapse and fade.
• Endovenous Laser Ablation (EVLA): A laser fiber is inserted into the vein, emitting energy that closes the vein.
• Radiofrequency Ablation (RFA): Radiofrequency energy is used to heat and seal off diseased veins.
• VenaSeal Closure System: A medical adhesive is delivered to the vein via a catheter, sealing it shut.
• ClariVein® Therapy: This hybrid treatment combines mechanical disruption of the vein with a chemical agent, effectively closing damaged veins. It’s a promising option for patients with advanced vein disease.

These procedures are typically performed on an outpatient basis, with minimal downtime, allowing patients to resume normal activities shortly after treatment.

Preventing Varicose Veins and Chronic Venous Insufficiency

While not all cases of CVI are preventable, certain measures can reduce the risk:

• Stay Active: Regular physical activity, such as walking or swimming, enhances circulation and strengthens the calf muscles, which act as a “second heart” by pumping blood back toward the heart.

• Avoid Prolonged Standing or Sitting: If your job requires you to stay in one position for extended periods, take breaks to move around and stretch your legs.
• Maintain a Vein-Healthy Diet: Incorporate foods rich in fiber, antioxidants, and vitamins like Vitamin C and Vitamin E. These nutrients support vein health by reducing inflammation and improving elasticity.
• Hydration Matters: Proper hydration helps maintain optimal blood viscosity, reducing strain on veins.

Addressing Misconceptions About CVI

Many people mistakenly believe that spider veins or varicose veins are purely cosmetic concerns. While they may seem minor, these visible signs often indicate underlying venous insufficiency. The Cleveland Clinic emphasizes the importance of viewing these symptoms as potential red flags for deeper vein issues.

Common myths include:

• Myth: CVI only affects older adults.
• Fact: While age is a risk factor, young individuals, especially women during pregnancy, can develop CVI.
• Myth: Compression stockings are uncomfortable and ineffective.
• Fact: Modern compression stockings are designed for comfort and are clinically proven to improve circulation.
• Myth: Invasive surgery is the only option for treating CVI.
• Fact: Most patients benefit from minimally invasive outpatient procedures.
