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.
Interventional pulmonology is a relatively new field in pulmonary medicine. Interventional pulmonology uses endoscopy and other tools to diagnose and treat conditions in the lungs and chest.
These procedures may be offered by pulmonologists (lung specialists) who have undergone extra training. Cardiothoracic and other surgeons also routinely perform interventional pulmonology procedures.
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.
