Pulmonary Embolism Support Group

By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.

how likely is a second pulmonary embolism

Dr thinks my PE might have been because of knee replacement surgery on Mar 16, 2012. I had the PE on 6/26. I wonder what the chances of a second pulmonary embolism are.

I don't know the statistics and I'm not sure statistics always tell the whole story anyway, since there are so many variables to why one clots, but I'd suspect that given they think your clots are from the surgery, and you don't have any blood clotting factors, the risks are probably low.

Do you have any other risk factors for clots?

I think it depends on your situation. Like RMB said-what other risks do you have? I have factor V and protein c deficiency-that coupled with the fact that I had a dvt, pe, and then another clot in leg later makes me high risk. You may be lower risk due to less factors.

I agree that it's hard to say for certain, because I think that many times a clotting event is just a perfect storm type scenario, but surgery can be a major risk, so yours would be considered a provoked clot, which means unless they have tested for an found that you have some sort of genetic disorder, your risk for another clot is low, unless you were to have surgery again, and with now having had a clot the best option would be to do prophylactic anticoagulation if you ever need surgery again. Otherwise your risk of more PE is probably not terrible but talk to your doctor about your concerns.

The others have given pretty good advice. No one can guaranteed 'no second clot' but the chances may be low for you.

Test for other risk factors---- talk to your doctor.

I had my PE after knee surgery. They called it a provoked clot and didn't seem too interested in looking for other reasons. I eventually saw a hematologist and he order the round of tests looking for genetic factors and found out I'm Factor V Leiden positive. I'm so glad that now instead of considering it a freak occurrence, I'll be more proactive about clot prevention in my life.

Right. Even if they suspect it's from the surgery, it's a good idea to run genetic blood clotting tests after your course of warfarin to determine if you have a genetic disposition to a blood clot. But there are many many many patients who got blood clots solely from the surgery and have no genetic blood clotting factors.

    Hello to anyone reading this. So to begin, I have been constantly thinking about a guy that I really liked all throughout high school. We were friends, but not too close, because he wasn't one to open up or be outgoing most of the time. It's been a couple years since I last was in secondary school and since I saw him. I don't have his number because I was too nervous to ask. I am so confused as...
