The doctors made it seem insignificant by putting off treatment until "after the holidays." However, in talking to other doctors and research I have found out that a pulmonary embolism can be a cause of sudden death.
If a pulmonary embolus clogs the artery that provides blood supply to part of the lung it not only prevents the exchange of oxygen and carbon dioxide, it also decreases blood supply to the lung tissue itself, potentially causing lung tissue to die.
Basic testing for a pulmonary embolism may include Complete Blood Count, electrolytes, Blood Urea Nitrogen, Creatinine blood test, chest x-ray and electrocardiogram. Now that CT scan has become more sophisticated, it can be used to identify emboli. Contrast is injected into an intravenous line in the arm while the CT is being taken, and the pulmonary arteries can be visualized. There are risks with this test since some patients are allergic to the contrast and the contrast can be harsh on kidney function. Levi only has one kidney so this may not be the best test for him.
The first step for treatment in patients with normal vital signs is anticoagulation. An anticoagulation drug, such as Coumadin, is taken beginning immediately. This is usually suggested for a minimum of six months.
