A 29-year-old female asked:

How do you know if a clot has travelled from 1 lung to another?

Not quite that way: A blood clot doesn't travel from one lung to another. In order for that to happen, a blood clot would have to break loose from inside one lung, travel backwards towards the heart, cross over to the other vessel connecting the heart to the other lung, and go into the other lung. However, blood clots from the legs can simply flow through the heart and go to both lungs.

Ct scan: Helical ct scan of the chest would be the best test.
Dr. Creighton Wright

Unusual: Clots may go from elsewhere to both lungs but once out in the lung they do not go back upstream. May break up and go from main artery to distal pulmonary arteries.
