deep-vein thrombosis
C1Formal, Medical
Definition
Meaning
A blood clot (thrombus) that forms in one of the deep veins, usually in the legs.
A serious medical condition in which a blood clot forms in a deep vein, typically in the leg, which can break loose and travel to the lungs, causing a potentially fatal pulmonary embolism. Often associated with prolonged immobility, surgery, or certain medical conditions.
Linguistics
Semantic Notes
The term is highly specific to medical pathology. It is a hyponym of 'thrombosis'. 'Deep-vein' specifies the anatomical location as opposed to superficial veins. The term is often abbreviated to 'DVT' in both speech and writing.
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. Both use 'deep-vein thrombosis' and 'DVT'. British English more frequently uses the hyphen in the spelled-out form.
Connotations
Neutral and purely medical/clinical in both varieties.
Frequency
Equal technical frequency. Awareness among general public is high in both regions due to public health campaigns related to air travel ('economy class syndrome') and post-surgical care.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'deep vein' as 'глубокая вена' in a non-anatomical sense; it is a fixed term for 'глубокие вены'.
- Do not confuse with 'тромбоз' alone, which is more general; specify 'тромбоз глубоких вен' (ТГВ).
- The word 'thrombosis' is a medical Latin term, not an English descriptive phrase.
Common Mistakes
- Misspelling as 'deep-vain thrombosis'.
- Using 'deep-vein' without the hyphen when used attributively (e.g., 'deep-vein thrombosis risk' is correct).
- Pronouncing 'thrombosis' with stress on the first syllable (/ˈθrɒmbəsɪs/) instead of the second (/θrɒmˈbəʊsɪs/).

FAQ
Frequently Asked Questions
No. DVT is the clot in the deep vein (often the leg). A pulmonary embolism (PE) occurs if that clot breaks off and travels to block an artery in the lungs. DVT is a common cause of PE.
Common symptoms include pain, swelling, redness, and warmth in the affected leg. However, sometimes DVT can occur with few or no obvious symptoms.
DVT itself is not immediately fatal. The primary danger is if the clot embolises and causes a pulmonary embolism, which can be life-threatening. This is why prompt diagnosis and treatment are crucial.
Treatment typically involves anticoagulant medications (blood thinners) to prevent the clot from growing and new clots from forming. In severe cases, more invasive procedures like thrombolysis or insertion of a vena cava filter may be used.
