The DVT medical abbreviation stands for deep vein thrombosis, a clot lodged in a deep vein of the body, most often in the calf, thigh or pelvis. The main worry is that part of the clot can break off and travel to the lungs, causing a pulmonary embolism (PE).
DVT appears in two ways in medical records. It can be a diagnosis, found on an ultrasound, or a risk the team is working to prevent, as in DVT prophylaxis orders after surgery. Both uses are explained below, along with sample lines and the closely linked term VTE.

The DVT medical abbreviation, term by term
Deep means the vein lies within the muscles rather than just under the skin. Vein is a vessel carrying blood back to the heart. Thrombosis comes from the Greek word for clot, thrombos, and means a clot forming inside a vessel. So DVT describes a clot blocking part or all of a deep vein.
Three broad factors raise the risk, a set clinicians learn early: slow blood flow (long bed rest, long travel, paralysis), injury to the vessel wall (surgery, trauma), and blood that clots more easily (cancer, pregnancy, some hormones and inherited clotting conditions).
Signs that prompt a DVT check
A DVT in the leg often causes swelling of one leg, pain or tenderness in the calf or thigh, warmth and redness or color change. Some clots cause no symptoms at all. Signs that a clot may have reached the lungs include sudden shortness of breath, chest pain that is worse with a deep breath, a fast heartbeat or coughing blood, and these need emergency care right away.
How DVT is diagnosed and recorded
The main test is a venous duplex ultrasound of the leg. A blood test called D dimer helps rule out a clot when the chance is low. The table decodes a typical ultrasound result.
| Report phrase | Plain meaning |
|---|---|
| LLE venous duplex | Ultrasound of the veins of the left leg |
| Acute occlusive thrombus | A new clot that fully blocks the vein |
| Left popliteal vein | The deep vein behind the knee |
| Noncompressible | The vein does not flatten when pressed, a sign of clot |
| Impression: acute DVT | The radiologist concludes there is a new deep vein clot |
DVT prophylaxis orders in the hospital
Because hospital stays combine many risk factors, most admitted adults are assessed for clot risk. Prevention, called prophylaxis or ppx, may be mechanical, chemical or both.
Admission order set: "DVT ppx: heparin 5,000 units subcut q8h; SCDs when in bed; encourage ambulation." This sample line pairs a low dose blood thinner injection with inflatable leg sleeves and getting up to walk.
Early walking is one of the simplest prevention steps, so nurses often chart how many times a patient was up and moving.
Treatment terms you may see
Treatment centers on anticoagulants, often called blood thinners, which stop the clot from growing while the body breaks it down. Notes may list heparin or enoxaparin as a start, then an oral medicine such as apixaban or rivaroxaban, grouped as DOACs, or warfarin, which needs regular INR checks. Terms like provoked (linked to a clear trigger such as surgery) and unprovoked help the team decide how long treatment lasts. In selected cases a filter or a clot removal procedure is used. The plan always comes from the treating clinician.
DVT, VTE and PE side by side
| Term | Meaning |
|---|---|
| DVT | Clot in a deep vein, usually of a leg |
| PE | Clot that has traveled to the lung arteries |
| VTE | Venous thromboembolism, the umbrella for DVT and PE |
| SVT (in vein context) | Superficial vein thrombosis; in heart notes SVT means a fast rhythm instead |
Clot terms and many other condition labels are gathered on the diagnosis abbreviations page.
Use this to understand DVT in records and orders. Anyone with leg swelling or pain, or with questions about blood thinners, should speak with their own doctor, nurse or pharmacist.
Frequently asked questions
What does DVT stand for?
DVT stands for deep vein thrombosis: a clot that forms in one of the deep veins, most often in a leg. It can be serious because the clot may travel to the lungs.
What does DVT prophylaxis mean?
It means steps taken to prevent a clot, such as a low dose blood thinner, compression sleeves and early walking. Hospitals commonly order it for patients who are less mobile.
Is DVT the same as VTE?
DVT is one type of VTE. VTE, venous thromboembolism, includes both deep vein clots and clots that reach the lungs, called PE.
Can a DVT happen in the arm?
Yes. Clots can form in the deep veins of the arm, often linked to a central line or catheter, though leg clots are far more common.
What test confirms a DVT?
A venous duplex ultrasound is the usual test. A D dimer blood test can help rule out a clot when the overall chance is low, but it cannot confirm one on its own.
