Is the blood a blockage produced by the formation of a thrombus (clot blood), which can eventually cause an acute myocardial infarction. This condition occurs mainly in the deep venous system, composed of deep veins, located in the lower extremities.
Thrombosis can be caused by different factors, with four being the main ones. First of all, there is the decrease in the speed of blood flow, which in turn can be produced by the state of rest while lying down, wearing a splint or a plaster bandage, dehydration or a venous condition that suffered with anteriority.
Secondly, there are injuries to the vascular wall, caused by wounds, some inflammation or operation, even by venous alterations caused by age.
Also, the increase in blood clotting is the cause of thrombosis, which can be caused by medications, which cause the balance between clotting and dilution of clots to be altered.
Lastly, there is cancer. When a patient suffers from cancer, the chances of suffering thrombosis are increased by 4 to 20%, with thrombosis sometimes being the cause of death in patients, after having overcome the tumor itself.
On the other hand, the symptoms that originate from thrombosis are pain and swelling in the calf and / or thigh, depending on the location of the clot.
In this sense, thrombosis can be classified according to the location or level of occlusion it reaches.
Depending on the location, it can be: a precipitation thrombosis (white clot), hyaline thrombosis or clotting thrombosis (red clot). The latter represents a high level of severity, since it can cause the death of structures, ischemia or paralysis in the muscles, if the clot or thrombus is in a vein.
Also, depending on the location of the vein, cavernous sinus thrombosis (severe), deep vein thrombosis (medium severity) or superficial thrombophlebitis (mild) may occur.
Due to its level of occlusion, thrombosis can be formed by occluding or mural thrombi or clots, which represent complete and partial obstruction of the vessel, respectively.
