Deep Vein Thrombosis (DVT) Support Group
Deep-vein thrombosis, also known as deep-venous thrombosis or DVT, is the formation of a blood clot ("thrombus") in a deep vein. It can be caused by something preventing blood from circulating or clotting normally. Join the support group if you are coping with DVT and find others who are going through the same challenges.

I don't think anyone here can really tell you whether to stay on it or not. I think you have to evaluate the anticoagulant risks against the risk of getting another clot and go from there.
Sometimes when a doc tells me I have a choice but I'm not sure what to do, I pull out the old, if it was your wife, sister, daughter, mother, etc what would you tell her. That seems to evoke an actual opinion. Obviously you'd not say daughter since you're a dude, but you get the picture.
"I don't think anyone here can really tell you whether to stay on it or not. I think you have to evaluate the anticoagulant risks against the risk of getting another clot and go from there."
There are intermediate options to consider though - staying on Coumadin at reduced dose 1.5 - 2.5 INR range for example, or do away with the coumadin dose altogether, but take a daily aspirin which has been shown to be beneficial at preventing clotting.
Also, consider what general predispoing factors you may have - Are you really tall? Overweight? Smoker? Frequent long haul traveler? Any or all of these factors may make you lean more towards continuing therapy.
The opposite is true as well - do you juggle chainsaws as a hobby? :-) Work as a meat cutter? Race car driver? Etc... Those factors would make you lean more towards discontinuing coumadin therapy.
Whatever the case, it is good you have options and good that you are thinking it through carefully.
Unprovoked (idiopathic) DVT: long-term, if risk for bleeding not very high. Re-evaluation every so often (once per year?) to determine whether long-term treatment is still the right thing to do.
Given my controlled INR and lack of any real dangerous activities, I would think I am a low risk of bleeding. In addition I recall finding a paper that said a similar thing, especially for males, whereas for women it would be more appropriate to d/c treatment.
My discontinue option would be the aspirin regimen, then re-check d-dimer after 1 month. My main worry is that I can be a bit of a worrywart, and I wonder if every time I get a leg cramp I'm going to be running to the hospital to get my d-dimer checked.
