What is Deep Vein Thrombosis?

DVT Blog

Deep Vein Thrombosis is also known as DVT, is a blood clot that forms in a deep vein within the body. Blood clots occur when blood thickens and clumps together, most deep vein blood clots occur in the lower leg or thigh. Although, they can also occur in other parts of the body. 

A blood clot in a deep vein can also break off and travel through the bloodstream, when a blood clot travels to the lungs, blocking blood flow, the condition is called Pulmonary Embolism (PE). PE is a very serious condition, it can damage the lungs and other organs in the body and may even cause death. Blood clots in the thigh are more likely to break off and cause PE than blood clots in the lower leg or other parts of the body. Blood clots can also form in veins closer to the skin’s surface. However, these clots do not commonly break off and cause PE.


Only half of those who have DVT have signs or symptoms, signs and symptoms occur in the leg affected by the deep vein clot. They can include swelling of the leg or along a vein in the leg, pain or tenderness in the leg, increased warmth in the area of the leg that’s swollen or in pain, and red or discoloured skin on the leg.

Symptoms of DVT:

Please note In some cases, there may be no symptoms of DVT, if symptoms do occur they can include:

  • Pain, swelling and tenderness in one of the legs or arms, often described as a cramp
  • A heavy ache in the affected area
  • Warm to touch in the area of the clot
  • Red skin, particularly at the back of the leg below the knee
  • A client with a DVT may complain of unilateral leg pain and swelling

Steps To Take:

  • DVT usually, (although not always) affects one leg, the pain may be worse when you bend your foot upward towards your knee.
