Blood clot

Symptoms: 
  • With atrial fibrillation, in which no symptoms occur until a thrombus embolizes.
  • If the clot embolizes to an artery in the brain, the symptoms will be that of stroke.
  • If the artery involved supplies blood to the bowel, symptoms may include abdominal pain and bloody bowel movements.
  • In a leg or arm, the blood clot or deep venous thrombosis can act as a dam and block blood returning to the heart. This may cause inflammation of the vein, or thrombophlebitis. Common symptoms include swelling, redness or discoloration, warmth, and pain.
  • The major complication of a deep venous thrombosis occurs when the clot breaks off and travels to the lung, causing a pulmonary embolism. Symptoms include chest pain and shortness of breath. This is a potentially life-threatening condition depending upon the extent of the lung tissue that loses blood supply.

Symptoms of arterial clot depend upon which organ is losing its blood supply.

  • If it is located in a coronary artery, there may be signs of heart attack.
  • Cerebral artery occlusion by clot will manifest in signs of stroke.
  • A patient with an arterial clot to an arm or leg will develop a painful, cool, pulseless extremity.
Tests to diagnose: 

The tests include physical examination, complete blood count and platelet count. 

Treatment: 

Anticoagulants, or "blood thinners," are used as routine treatment for excessive blood clotting. Warfarin and heparin are two types of blood thinners. Short-term treatments may include treatment with antithrombin factor and protein C.
