Have you or your doctors considered a blood clot? There are different types of blood clots:
A thrombus is a blood clot that forms along the wall of the heart or a blood vessel. This type of clot can slow blood flow, and if the clot becomes large enough, it may stop the flow of blood in the vessel.
An embolus is a clot that forms in one area of the body, travels through the bloodstream, and lodges in another vessel in the body. Emboli are less common and more dangerous, because they can cause a sudden blockage in blood flow (embolism), which could be fatal. An embolism occurring in an artery will block blood flow to an organ or tissue, and could cause tissue damage or death. An embolism in:
* a cerebral (brain) artery can cause a stroke
* a coronary artery can cause a heart attack
* a pulmonary (lung) artery can cause shortness of breath or death
* a retinal artery can cause sudden blindness in one eye
* an artery supplying blood to a limb can cause tissue damage and possibly gangrene
* any artery leading to an organ can cause loss of that organ's function
Inflammatory diseases, such as Lupus, can cause blood clots. Plaque formation in the arteries (atherosclerosis) and damaged blood vessels both increase the chance of blood clots because they slow blood flow and provide a place for platelets to collect and form a clot. Genetic factors also play a role in tendency to form blood clots. Liver damage and cardiovascular disorders can also cause blood clots.
Symptoms can include extreme dizziness that occurs without warning. Sudden complete or partial blindness in one eye could indicate a clot within the retinal artery. A hard blue bulge in a vein, or unexpected pain in an arm or leg, along with numbness, weakness, or another sign that blood is not reaching the area, could indicate a blood clot. Blisters or ulcers on the skin may occur as well. A clot in an artery near a major organ like the heart or lung will produce pain or decreased activity in that organ.
