Deep Vein Thrombosis (DVT) is a serious vascular condition that occurs when a blood clot forms in the deep veins, typically in the legs. If left untreated, DVT can block circulation, cause long-term leg pain and swelling, and lead to life-threatening complications such as pulmonary embolism (PE)–a condition where a blood clot travels to the lungs.
At Vascular Surgery Associates, our expert vascular specialists in Los Angeles and Santa Monica provide advanced DVT treatment options, including anticoagulation therapy, catheter-based clot removal, and vena cava filter placement, ensuring timely intervention and long-term vein health.
Understanding Deep Vein Thrombosis (DVT)
DVT occurs when blood clots form in the deep veins, preventing proper circulation and increasing the risk of clot migration. According to the Centers for Disease Control and Prevention (CDC), approximately 900,000 Americans develop DVT annually, with one-third of cases leading to serious complications such as pulmonary embolism.
Without proper treatment, DVT can lead to chronic venous insufficiency, leg ulcers, and post-thrombotic syndrome (PTS), causing long-term discomfort and mobility issues.
What Are the Symptoms of DVT?
The symptoms of Deep Vein Thrombosis vary, and some patients may experience no noticeable warning signs. However, common indicators include:
- Swelling in one leg (typically below the knee)
- Pain or tenderness that worsens when standing or walking
- Warmth in the affected area
- Skin discoloration (red or bluish tone)
- Leg cramping, especially at night
If you experience sudden shortness of breath, chest pain, or rapid heart rate, seek emergency medical attention immediately, as these may indicate a pulmonary embolism.
Who is at Risk for DVT?
Certain medical conditions and lifestyle factors can increase the risk of developing deep vein thrombosis:
Prolonged Immobility
Long periods of sitting (airplane travel, bed rest, or hospitalization) increase clot formation risk
Surgery or Trauma
Recent surgery, fractures, or injuries trigger clotting mechanisms
Pregnancy & Hormonal Changes
Increased estrogen levels (birth control, hormone replacement therapy, pregnancy) affect blood clotting
Obesity
Extra weight puts pressure on veins and slows circulation
Smoking
Damages blood vessels and raises clotting risks
Family History of Clotting Disorders
Genetic predisposition increases the likelihood of DVT
If you have multiple risk factors, early screening and preventive strategies can help reduce your chance of developing DVT.
How is DVT Diagnosed?
At Vascular Surgery Associates, we use advanced imaging techniques to accurately diagnose DVT and assess the severity of vein blockage.
Doppler Ultrasound
The gold standard for DVT detection, this non-invasive imaging test evaluates blood flow and identifies clots
D-Dimer Blood Test
Measures clotting activity in the bloodstream
CT or MR Venography
Provides detailed images of deep veins to confirm clot presence in complex cases
Catheter-Based Venography
Uses contrast dye and X-rays to visualize deep vein obstructions
Early diagnosis is critical for preventing complications and ensuring the most effective treatment approach.
Advanced Treatment Options for Deep Vein Thrombosis
Our vascular specialists in Los Angeles and Santa Monica provide a range of minimally invasive and interventional treatments to prevent clot progression and long-term vein damage.
Anticoagulation Therapy (Blood Thinners)
The first line of treatment for most DVT cases is anticoagulation therapy, which helps prevent further clot formation and reduces the risk of pulmonary embolism. Commonly used medications include:
Warfarin (Coumadin)
Requires regular blood monitoring and dietary adjustments
Direct Oral Anticoagulants (DOACs)
Includes Xarelto, Eliquis, and Pradaxa, offering effective clot prevention without frequent blood tests
Most patients require anticoagulation therapy for 3 to 6 months, though longer treatment may be necessary for recurrent clots.
Catheter-Directed Thrombolysis (Clot Dissolution Therapy)
For severe DVT cases affecting the iliac or femoral veins, clot removal is essential to prevent long-term swelling and post-thrombotic syndrome.
- A catheter is inserted directly into the clot
- Clot-dissolving medication (thrombolytic therapy) is delivered
- In some cases, a specialized clot-breaking device is used to clear the vein
This minimally invasive procedure restores normal blood flow and significantly reduces the risk of complications.
Inferior Vena Cava (IVC) Filter Placement
For patients who cannot take anticoagulants or develop clots despite medication, an IVC filter is placed in the inferior vena cava (the body’s largest vein) to prevent clots from traveling to the lungs.
- Inserted through a small puncture in the groin
- Acts as a “net” to trap clots before they reach the lungs
- Temporary filters can be removed when risk declines
IVC filters are an effective option for high-risk patients and prevent life-threatening complications.
Frequently Asked Questions About Deep Vein Thrombosis
Yes, if untreated, DVT can lead to a pulmonary embolism (PE), which can be fatal. Early diagnosis and treatment are critical.
Most patients require 3-6 months of anticoagulation therapy, though severe cases may require clot removal procedures or longer treatment durations.
Yes, staying active, maintaining a healthy weight, avoiding prolonged immobility, and wearing compression stockings can reduce DVT risk.
Untreated DVT can lead to chronic pain, swelling (post-thrombotic syndrome), and long-term circulation issues. More dangerously, it can result in pulmonary embolism.
If you experience leg swelling, pain, redness, or warmth, seek immediate evaluation. If symptoms of shortness of breath or chest pain develop, seek emergency medical care.
