Deep Vein Thrombosis (DVT)

Symptoms, Risks, and Advanced Vascular Care  

Ahmedabad

Deep Vein Thrombosis (DVT) is a serious, potentially life-threatening medical condition that occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body—most commonly in your legs, thighs, or pelvis.

A deep vein blood clot can partially or completely block the return of blood to your heart. It can also break free and travel through your circulatory system, leading to a critical emergency.

As a leading cardiothoracic and vascular surgeon in Ahmedabad, Dr. Ishan Gohil specializes in advanced diagnostic scanning and endovascular therapies to dissolve clots, restore healthy circulation, and prevent life-threatening pulmonary complications.

Symptoms of Deep Vein Thrombosis

DVT can develop silently, showing only mild symptoms or none at all. When symptoms do occur, they usually present on only one side of the body (unilateral) and may include:

• Sudden Swelling: Pronounced, unexplained swelling in one leg, ankle, or arm.

• Localized Pain or Tenderness: An aching or cramping sensation in the calf or thigh that often feels like a muscle pull, particularly when standing or walking.

• Skin Warmth: The skin over the affected, swollen area feels noticeably warmer than the surrounding tissue.

• Redness or Discoloration: The skin on your leg or arm may look reddish, pale, or take on a bluish/purplish tint.

• Surface Vein Dilation: Veins near the surface of the skin may appear larger, engorged, or more visible than usual.

The Ultimate Danger: Pulmonary Embolism (PE)

If a deep vein blood clot breaks loose from its original site, it travels through the bloodstream and can lodge itself in the arteries of your lungs. This is a Pulmonary Embolism (PE)—a critical medical emergency.

Seek Immediate Emergency Medical Attention if You Experience:

• Sudden, unexplained shortness of breath

• Sharp, stabbing chest pain that worsens when taking a deep breath

• A sudden, dry cough or coughing up blood

• Dizziness, lightheadedness, or fainting (syncope)

What Causes a Deep Vein Blood Clot?

DVT is primarily caused by a combination of three factors, clinically referred to as Virchow's Triad: slow-flowing blood (stasis), damage to the inner lining of a vein, and hypercoagulability (a high tendency for blood to clot).

• Prolonged Immobility: Being inactive for long periods—such as during extended bed rest after surgery, a long hospital stay, or traveling in a car or plane for more than four hours—causes blood flow in your legs to pool and become sluggish.

• Vein Injury or Trauma: Physical damage to a vein from surgery, fractures, or severe muscle trauma can trigger clot formation.

• Increased Inflammation: Systemic inflammation from infections, severe illnesses, or major surgery naturally increases the body's clotting factors.

Key Risk Factors:

• Being over the age of 40

• A personal or family history of blood clotting disorders

• Active cancer or undergoing chemotherapy treatments

• Pregnancy or having recently given birth

• Using tobacco products (which damages the vessel lining)

• Underlying chronic conditions such as heart failure, kidney disease, or severe varicose veins

• Obesity or carrying excess body weight

Long-Term Complications of DVT

If DVT is not diagnosed and treated quickly, it can lead to permanent damage:

• Pulmonary Embolism (PE): As detailed above, this is the most critical and life-threatening complication of DVT.

• Post-Thrombotic Syndrome (PTS): Chronic pooling of blood from damaged vein valves can cause long-term venous hypertension. This leads to persistent leg pain, chronic swelling, skin discoloration, and in severe cases, painful open sores called venous ulcers.

How is Deep Vein Thrombosis Diagnosed?

A prompt and accurate clinical assessment is vital. Dr. Ishan Gohil utilizes advanced diagnostic tools to confirm the presence of a clot:

• Vascular Duplex Ultrasound: This is the gold-standard, non-invasive imaging test. It uses high-frequency sound waves to visualize the deep veins and detect blockages or sluggish blood flow.

• D-Dimer Blood Test: Measures a specific substance in your blood that is released when a blood clot breaks down. An abnormally high level suggests a clot may be present.

• CT Venogram / CT Scan: Advanced imaging used to identify blood clots in the veins of your pelvis, abdomen, or lungs (PE).

• Magnetic Resonance Venography (MRV): An MRI-based scan that provides highly detailed images of the veins in complex areas of the body.

Advanced Treatment Options Offered by Dr. Ishan Gohil

The goals of DVT treatment are to prevent the clot from growing, stop it from breaking off into the lungs, and reduce your risk of developing future clots. Dr. Gohil tailors treatments to your specific clinical needs:

1. Anticoagulant Therapy (Blood Thinners)

The primary line of defense. Medications such as heparin, warfarin, or newer direct oral anticoagulants (like apixaban or rivaroxaban) help thin the blood. While they do not actively dissolve existing clots, they prevent the clot from growing larger and stop new clots from forming, allowing your body to naturally break the clot down over time.

2. Thrombolytic Therapy ("Clot Busters")

For severe, extensive blockages (such as iliofemoral DVT), Dr. Gohil may perform catheter-directed thrombolysis. A thin tube is guided directly into the clot to deliver powerful clot-dissolving medications, rapidly restoring blood flow and protecting the vein's valves.

3. Surgical Thrombectomy

In rare, severe cases where medications are unsafe or ineffective, Dr. Gohil can perform a minimally invasive vascular procedure to physically extract the large blood clot using specialized catheter devices.

4. Inferior Vena Cava (IVC) Filter

For patients who cannot safely take blood thinners due to bleeding risks, a specialized basket-like device called an IVC filter can be surgically placed in the body's largest vein. This filter catches traveling clots before they can reach the lungs.

Practical Prevention and Home Care

If you are at risk for DVT or are recovering from a clot, simple lifestyle habits can keep your blood flowing smoothly:

• Keep Moving: Avoid sitting still for more than an hour. During long flights or road trips, stretch your calves, rotate your ankles, or take a short walk every 30 minutes.

• Post-Surgery Mobility: Get out of bed and walk as soon as safely possible after any surgical procedure.

• Wear Compression Stockings: Medical-grade, knee-high compression stockings gently squeeze the calves to prevent blood from pooling and reduce leg swelling by up to 50%.

• Stay Well-Hydrated: Drink plenty of water, especially during travel, to maintain healthy blood viscosity.
