What is intraluminal thrombus?

Intraluminal thrombus refers to a blood clot formed in the blood vessel, which restricts blood flow through the lumen.

When the blood vessel is damaged, your body uses platelets and fibrin to form a blood clot. If the blood clot breaks free from the thrombus site and circulates in the bloodstream, it forms an embolus. An embolus is a dangerous complication of thrombosis and is potentially fatal.


Endothelial injury, stasis and other disorder of blood all may cause intraluminal thrombus.

If the following symptoms are present, you may have a higher risk of getting a thrombus:

  • Smoking
  • High blood pressure and high cholesterol
  • Trauma
  • Cancer
  • Overweight
  • Diabetes


Depending on where the thrombus forms, signs and symptoms of the disease may vary.

The common symptoms are described as followed:

  • Pain
  • Swelling
  • Heart attack
  • Unstable angina
  • Ischemic stroke
  • Shortness of breath


Thrombus is treated with certain medications and therapies. In often cases, the doctor may prescribe heparin and warfarin to inhibit the formation and growth of the existing thrombus.

Besides, doctor may prescribe anticoagulants to prevent the blood clot from breaking off. Also, the doctor might  advise the patient to wear compression socks and do more exercises.

If there’s an emergency, surgery is also an available option.


Though it’s not possible to completely prevent the formation of a thrombus, there are options to reduce the risks:

  • Quit smoking
  • Maintain a healthy weight
  • Do exercises on a regular basis
  • Eat healthily
