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.
If you don't get any responses here, you may want to try posting on the DVT board to see if someone is or was in a similar situation.

Appears your doc was right, so no decision to make? As usual, its a balance of risks and having factor V increases the risks, but its certainly not a cert that you'll have a recurrence.
Aspirin may have a minor anti coag effect, although some tests say it has no effect. Personally, I wouldn't bother, but I can understand if people do.
I would probably be concerned, and coumadin is inexpensive. I think the blood workups are around $35 per draw. What I would be asking is how much of a risk the Factor V Leiden 1 is compared to other disorders. I would need some numbers to put it in perspective.
Let us know how it works out.

The results do vary a bit between studies. The real measure is the number of recurrences while on the drug and this needs to be balanced with bleeding/bone loss/... side effects. Aspirin reduces the recurrence risk a bit, although not nearly as much as the standard anti coags.
BTW indwen, I'm not factor v positive and my attempt to stop warfarin was rubbish :-), so the above was just what I'd read in several places. But the opinion seems to be that while factor v raises the clot risk a bit, best advice is not to stop on warfarin after 1st set of clotts.
