definition
A blood clot formed from platelets and other elements that forms in a blood vessel in a living organism, and causes thrombosis or obstruction of the vessel at its point of formation or travel to other areas of the body.
Blood clots (thrombi) are clumps of a naturally-occurring protein called fibrin which can accumulate in a blood vessel.
Essentially the action of streptokinase is to boost the fibrinolytic system and remove thrombi which are potentially life-threatening.
Venous thrombi are formed by stasis and are mainly composed of red blood cells intertwined with fibrin.
Ninety percent of pediatric cases of renal vein thrombi occur in infants less than one year old; 75 percent occur in infants under one month of age.
