If i have been cleared of dvt via 3 ultrasounds and a negative d dimer. is it possible to still have a pulmonary embolism?

DVT. AND PE: Is highly unlikely. PE come from larger veins and US would detect a clot. Negative D Dimer is reassuring.

Probably not.: If you have any chest symptoms a ct of the lungs rules out that possibility. So with the tests you already had it appears to me that any blood clot has been ruled out in the lower extremities.

Unlikely: Negative d- dimer is very predictive that no unusual clotting is happening.
