Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the legs but sometimes in the arms. While DVT can be serious, early detection allows for timely treatment and reduces the risk of complications such as pulmonary embolism, which can be life-threatening.
An ultrasound scan is the most effective, non-invasive way to detect DVT. At Clarity Ultrasound, we provide professional, accurate, and safe assessments of the veins in the arms and legs to help guide appropriate care.
Common Symptoms of DVT
Typical signs of a DVT include:
- Swelling in one leg or arm
- Pain, tenderness, or cramping, often in the calf or thigh
- Warmth or redness over the affected area
- Skin that appears discolored or tight
Some people may experience few or no symptoms, which is why risk factors like recent surgery, immobility, pregnancy, hormone therapy, or a personal/family history of blood clots should always be discussed with a healthcare professional.
Red Flags: When to Go to A&E Immediately
DVT can lead to serious complications. If you experience any of the following, the safest place to attend immediately is A&E:
- Sudden shortness of breath or chest pain
- Rapid heartbeat or feeling faint
- Severe swelling or pain that comes on suddenly
- Severe discoloration (blue or very pale skin) in the affected limb
These could be signs that a blood clot has travelled to the lungs (pulmonary embolism) or that the clot is causing significant blockage.
What an Ultrasound Can Reveal
For non-urgent cases, a venous ultrasound can assess the veins for:
- The presence of a blood clot in deep veins
- Abnormal or restricted blood flow
- Superficial clots or other vein abnormalities
- Structural changes in the veins
Detecting a clot early allows for prompt treatment, usually with anticoagulant medication, which reduces the risk of complications. If no clot is detected, the scan provides reassurance and helps guide further investigation if necessary.
