Deep vein thrombosis is a condition in which blood clots occur, usually in veins in the lower leg, thigh, pelvis, and sometimes arms. It is a serous but preventable and treatable condition. If not treated promptly it can be fatal.

It is often under diagnosed, so it is important to seek medical care if symptoms appear.


If  timely treatment is not offered clot from the veins can travel to your heart resulting in heart attack like condition called Pulmonary Embolism(PE) which is fatal.


Some common factors that may increase the risk of DVT and PE include:

  • Long distance journey , especially for more than 8hrs.
  • Injury to a vein caused by a fracture, muscle injury or major surgery
  • Sluggish blood flow or lack of blood flow due to bed rest, limited movement, sitting, and crossing legs for a long time, and paralysis
  • Increased estrogenfrom birth control pills hormone replacement therapy, or pregnancy
  • Cancerand Chemotherapy agents
  • A personal or family history of DVT and PE or clotting disorders
  • Central venous catheters
  • Varicose veins


  • Swelling, pain, and tenderness in the extremities, especially on one side
  • Redness of the skin usually associated with the swelling, pain, and tenderness described above.

A PE can occur with or without symptoms of DVT. PE can be extremely serious. If any of the following signs of PE occur, the patient should see a doctor immediately:

  • Difficulty in breathing
  • Irregular or quickened heartbeat
  • Chest pain or discomfort, usually brought on by deep breaths
  • Coughing up blood
  • Low blood pressure, fainting, and feeling light-headed
  • Increased anxietyor nervousness.


Tests to diagnose deep vein thrombosis may include:

  • D-dimer test
  • Venous Doppler
  • Venography –
  • CTPA-CT pulmonary Angiograaphy to rule out PE


Blood Thinners- Heparin, Warfarin etc

Catheter-directed thrombolysis-

  • With imaging guidance, vascular surgeon inserts a thin tube (catheter) into and through a vein in your leg.
  • Hethen puts the tip of the catheter into the clot and infuses a clot-busting drug directly into it.

How Can You Prevent DVT?

Moving your legs around when you’ve been sitting for a while also helps keep your blood flowing. Walking around after being on bed rest can prevent clots from forming.

If you’re traveling for 4 hours or more, take breaks to flex and stretch your lower leg muscles. If you’re on a flight, walk up and down the aisle every half hour. On long car drives, pull over each hour to stretch. Wear loose-fitting clothes and drink plenty of water.
