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.
My clots are from 2005 and 2009 and both are still in my right leg. My understanding is past six months or so, the clots are pretty solidified and have become part of the vein wall. Some people still see some dissolving after that point (I don't think I have), but either way the clot shouldn't be a danger anymore ... and I don't think (although I'm not sure) that new clots can "grow" using the old clot.
I really can't say whether having a chronic clot makes it more or less likely that you'll clot again. I mean, if it's part of the vein wall, I don't know why it would have any effect on whether you clot again or not. I mean, I'm not a great example, since I have chronic clots and I've clotted three times ... but I really am the exception to the norm. I think there are plenty of people out there who never have a repeat ultrasound (and many people don't), and come off warfarin and go on with life. They might still have residual clotting and might not. Since there aren't any repeat ultrasounds on many patients (probably at least half, if not more), I don't know that you could conclusively say that chronic clotting does or does not increase your likelihood of re-clotting.
Also, just cause you have a residual clot, that doesn't mean you won't get any better. Other that my right leg being larger than the other one, I don't have pain or numbness or discoloration ... even though I have the chronic clotting.
Definitely write down your questions for your doctor. And, if you're still concerned, ask to be referred to a specialist. Maybe talking to a couple different doctors will help you feel better about things.
The clotting was just as extensive above my knee as below, but I don't have hardly any remaining pain above my knee. Almost all of my PTS pain strikes below the knee.
My long-winded point is that just because you have clotting left over doesn't necessarily mean that you will clot again or that you will experience any long-term pain problems.
I mean, most of us who are "long-timers" on these group are here because we're the exception in terms of multiple clots, not the norm. I've been on these boards more than three years and have seen dozens and dozens of people who are active for their six months of treatment, go off warfarin, and never come back. For most people (I think), they clot once and go on with life and never clot again. There's no reason to assume you won't be part of the 90% instead of the 10% (I'm working with the numbers you threw out ... not sure if they're correct or not.)
Hang in there and don't sink yourself into too deep a funk until you talk to your doc. I would suggest writing down all the questions you think of between now and your appointment. Nothing more annoying than walking out of an appointment you've waited a long time for and realizing that you forgot to ask THE question.
Hang in there.
Which takes me to the second factor in recurrent clotting which is just the mechanics of the veins. Your blood could potentially be fine but if the veins have large amount of undissolved (chronic) clot then it might in that part of the vein kind of "back up" blood flow, kind of like when traffic goes down from two lanes to one. Since the blood moves through that area more slowly it could increase risk of clotting again because when flow is interrupted, the cells can start to clot together. But usually chronic clot isn't something that's big enough to cause a huge risk that way, the clots really a more like a scar, the vein wall might look thicker there but it's not making a significant difference in how much blood can move through. The other big thing mechanically (which I believe is the more common issue) is that when we get clots the valves inside the vein basically don't work right. Now, the that might be kind of a minor thing (if the clot was small so only a small area of valves are injured) or it can be a bigger deal (if the original clot was present through the length of the vein).
Your doctor will not only have the details of your original clot but since he has done a repeat ultrasound, he knows how things stand now in your veins. You're right there is an increased risk of clotting, but actually there are pretty solid guidelines the doctors follow in terms of recommending whether someone stay on coumadin or not. So if you're doctor wants you to come off, then that's a pretty good indication that you're okay to come off. Even if you were to get a clot again sometimes during your life, it doesn't mean it'd be a week after coming off anticoagulants. My dad had a small clot in his leg and didn't have another for 20 years. Now I can guarantee that during those 20 years, being on coumadin would have been a far bigger risk for him as he's has several accidents including a bad head injury. And I agree with Toss, the number of people we've seen come through here and leave after they finish treatment is astounding compared to the handful of people who have stayed active here because we have clotted several times and have to stay permanently on coumadin. I personally think that unless your doctor recommends something different, it's best to just kind of put the whole clotting episode behind you. I think it's good to have a better awareness of taking care of our vascular health, obviously - making sure to be moving our legs often enough for the blood to move, and staying well hydrated, etc, all the things you already know now.
Just curious why you can't do the 12k. I mean, if you're still having lots of pain and swelling, I could see it. But, if you're off thinners and you're not having issues, I don't know why you couldn't do the 12K.
Just my two cents, of course. You could always check with your doc on this kind of thing too.
For me, after my clot in 1992 which started in my ankle extended to my hip, I had a lot of valve and scar damage. Wearing compression stockings definitely help to reduce the swelling (not necessarily the pain). For me, running was problematic because the damage valves would expand to golf ball size lumps. I didn't have the same problem biking so I eventually gave up running.
