If a large blood clot blocks the artery in the lung, blood flow may be completely stopped, causing sudden death. A smaller clot reduces the blood flow and may cause damage to lung tissue. But if the clot dissolves on its own, it may not cause any major problems.
If your doctor suspects sarcoidosis, he or she will do the following:
Review your medical history
Perform a physical exam
Order chest X-rays and blood tests that may aid in the diagnosis
In 90% of people with sarcoidosis, chest X-rays show abnormalities. Many patients also have a low white blood cell count. Your doctor may also order pulmonary-function tests, which measure how well your lungs are working. Tissue biopsies (tests on small tissue samples) from your lungs may be done to...
Doctors will consider aggressive steps when they are treating a large, life-threatening pulmonary embolism.
Chronic or recurring pulmonary embolism
Blood clots that cause pulmonary embolism may dissolve on their own. But if you have had pulmonary embolism, you have an increased risk of a repeat episode if you do not receive treatment. If pulmonary embolism is diagnosed promptly, treatment with anticoagulant medicines may prevent new blood clots from forming.
The risk of having another pulmonary embolism caused by something other than blood clots varies. Substances that are reabsorbed into the body, such as air, fat, or amniotic fluid, usually do not increase the risk of having another episode. Cancer increases the risk of blood clots.
