From the Guidelines
Deep Vein Thrombosis (DVT) commonly presents with signs and symptoms such as swelling, pain, tenderness, warmth, and redness in the affected area, typically in one leg, as noted in the most recent guidelines 1. The classic signs include unilateral leg swelling, pain that worsens when standing or walking, visible surface veins, and skin that feels warm to the touch. Some patients may experience a dull ache, cramping, or heaviness in the affected limb. It's essential to consider that up to 50% of people with DVT may not show any symptoms at all, making it a potentially silent condition, as highlighted in the study by Wells et al 1. Key signs and symptoms to look out for include:
- Swelling of the unilateral extremity
- Heaviness in the extremity
- Pain in the extremity
- Unexplained persistent calf cramping
- Swelling in the face, neck, or supraclavicular space Risk factors for DVT include prolonged immobility, recent surgery, pregnancy, hormonal contraceptives, cancer, and genetic clotting disorders. Given the potential for serious complications like pulmonary embolism, it is crucial to seek emergency care if DVT is suspected, especially in individuals with risk factors or sudden onset of symptoms, as emphasized in the guidelines 1. Diagnosis is typically made through a combination of physical examination, ultrasound, D-dimer blood tests, and sometimes venography or MRI. Early detection and treatment with anticoagulants can prevent potentially life-threatening complications, as noted in the study 1.

From the Research
Signs and Symptoms of Deep Vein Thrombosis (DVT)
The signs and symptoms of DVT can vary, but common symptoms include:
- Pain or tenderness in the affected limb, which can be severe in some cases 2
- Swelling or edema in the affected limb 3
- Erythema or redness in the affected limb 3
- Dilated veins in the affected limb 3
- Cyanosis or discoloration of the affected limb, which can be a sign of severe DVT 2
- Paresthesias or numbness in the affected limb 2
- Inability to move the toes or feet of the affected limb 2
Severe Complications of DVT
In some cases, DVT can lead to severe complications, including:
- Phlegmasia cerulea dolens (PCD), a rare and life-threatening condition characterized by severe pain, swelling, and cyanosis of the affected limb 2
- Compartment syndrome, which can lead to circulatory shock and multiorgan failure 2
- Pulmonary embolism, which can be fatal if not treated promptly 3
- Post-thrombotic syndrome, which can cause long-term damage to the affected limb 3
Diagnosis and Treatment of DVT
Diagnosis of DVT typically involves a combination of clinical assessment, evaluation of pre-test probability, and objective diagnostic testing, such as D-dimer tests and compression ultrasound 3. Treatment of DVT usually involves anticoagulation therapy, which can include parenteral anticoagulants, warfarin, or direct oral anticoagulants (DOACs) 3. The choice of treatment depends on the individual patient's risk factors and medical history.
