Question: blood clots in lungs and infections

Could a blood clot in the lung be caused by an infection caused by an allergic reaction to heprain?

I don't know if it's necessarily caused by an infection, but the answer is yes, a person can get a blood clot in the lung (called a pulmonary embolism) as a result of heparin induced thrombocytopenia, also known as HIT, which is an allergic reaction to heparin.

I want to say the statistics on this show that HIT can occur in about 30% of patients receiving heparin, but that the rate of complications such as a pulmonary embolism are much, much lower. Don't quote me on these stats though... just something I'm pulling from a memory that could be incorrect.

Try doing a Google search on HIT.
