What Is a Deep Vein Thrombosis (DVT)?

Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a deep vein within your body, typically in the legs. Although long periods of inactivity can increase your risk, DVT can develop for many different reasons. If left untreated, part of the blood clot can break loose and travel to the lungs, causing a pulmonary embolism (PE), a potentially life-threatening complication.

Learning the symptoms, risk factors, and treatment options is crucial to helping you recognize warning signs early and protect your vein health. In this blog, Dr. Vinay Satwah, lead vein physician at our Center for Vein Restoration (CVR) clinic in Greenbelt, MD, explains the key symptoms, risk factors, and treatment options for DVT so you can better understand when to seek care.

If you’re experiencing leg pain, swelling, or have risk factors for vein disease, don’t wait. Schedule a consultation with Center for Vein Restoration (CVR) to receive prompt, expert evaluation in a safe outpatient setting.

How Does a DVT Start?

Deep vein thrombosis occurs when circulation slows or becomes disrupted, allowing a blood clot to form in a deep vein. These clots can vary in size and may partially or completely block blood flow, leading to uncomfortable and sometimes alarming symptoms.

Common signs of a DVT include:

• Swelling in one leg
• Aching, cramping, or tenderness
• Warmth in the affected area
• Redness or discoloration

These symptoms are most often felt in the calf, but they can also occur in the thigh or pelvis. Some people may have very mild or no symptoms at all, underscoring the importance of awareness.

It’s also possible for clots to form in superficial veins, often associated with varicose veins, causing localized pain and warmth. While these are generally less dangerous than DVTs, they still require medical evaluation.

Why DVT Can Be Dangerous

The most serious risk of deep vein thrombosis occurs when a clot breaks free and travels through the bloodstream. If it reaches the lungs, it causes a pulmonary embolism (PE), a serious condition that can block oxygen flow and strain the heart.

Pulmonary embolism symptoms include:

• Sudden shortness of breath
• Sharp or painful breathing
• Coughing up blood
• Rapid heartbeat or palpitations

According to the Centers for Disease Control and Prevention, DVT and PE, collectively known as venous thromboembolism (VTE), affect as many as 900,000 Americans each year. Prompt medical attention can significantly reduce the risk of serious complications.

Diagnosing and Treating Deep Vein Thrombosis

If a DVT is suspected, your provider will typically begin with a non-invasive ultrasound, which can detect clots and assess blood flow. In certain cases, additional imaging such as a CT scan or MRI may be recommended. A blood test called a D-dimer may also help rule out clotting.

The good news is that DVT is highly treatable, especially when identified early. Options include:

• Blood thinners (anticoagulants): These medications help prevent the clot from growing and reduce the risk of new clots forming. They may be taken as pills or injections and are typically prescribed for at least three months.
• Monitoring: Some small clots, particularly in the calf, may be safely monitored with follow-up imaging.
• IVC filter: For patients who cannot take blood thinners, a small device called an inferior vena cava (IVC) filter may be placed to help prevent clots from reaching the lungs.

Your care team will tailor treatment based on your individual health, lifestyle, and risk factors.

DVT Risk Factors

Anyone can develop a DVT, but certain factors increase your risk. These include:

• Prolonged inactivity, such as long flights or desk jobs
• Recent surgery or injury
• Personal or family history of blood clots
• Age over 65
• Obesity
• Pregnancy
• Cancer or certain medications, including hormone therapy and birth control
• Smoking
• Heart or kidney disease
• Chronic venous insufficiency

Understanding your personal risk factors is an important step in prevention and early detection.

Preventing Blood Clots

While not all DVTs can be prevented, there are many simple steps you can take to lower your risk:

• Stay active and move regularly, especially during long periods of sitting
• Take breaks when traveling by standing, stretching, and walking every one to two hours
• Wear medical-grade compression stockings to help improve circulation, particularly if you sit or stand for long periods
• Maintain a healthy weight and avoid smoking
• Manage chronic conditions, including vein disease or heart conditions, with proper medical care

Small, consistent habits can go a long way in supporting healthy blood flow and reducing your risk.

Frequently Asked Questions

1. Can dehydration increase the risk of DVT?
Yes, dehydration can slightly thicken the blood, which may contribute to clot formation, especially when combined with other risk factors, such as inactivity.

2. Can DVT happen in both legs at the same time?
While DVT most commonly affects one leg, it can occur in both legs, especially in people with underlying medical conditions or higher clotting risk.

3. Is it safe to exercise if I have a DVT?
In many cases, gentle movement is encouraged, but your physician will guide you on safe activity levels based on your specific condition.

4. Can younger people develop DVT?

Yes, although risk increases with age, younger individuals can develop DVT, especially if they have risk factors such as an injury, a recent surgery, genetic conditions, or prolonged inactivity.
