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.
Despite what you see on here, most people have a clot, come off the thinners, and never clot again. Do remember that those of us who have clotted multiple times are often hanging around on these boards because we're the exceptions. It might look like most people reclot, if you only look at the people on these boards. But that really isn't true... its just that those who don't reclot aren't here... they're out living their lives.
To evaluate the risk of another clot after stopping on blood thinners is really hard to predict. If you provide more information about the cause of your DVT, how extensive it was and on the recovery, then I can attempt to speculate on it, then again, it would only be speculations...
I agree with Toss wholeheartedly to remember that most people don't re-clot if they don't have a clotting disorder or other risk factor. Of course having one DVT does increase a persons chances of getting another overall; however, if it were that prevalent of a risk, no one would ever be taken off warfarin, right?
The person who manages your warfarin may not be qualified to make the determination of whether to re- scan or not.
It's good to seek information here and get people's opinions,but talk to your doc about what the test results mean for you, and why he feels you're ok to go off warfarin or why he thinks you don't need a re-scan. Ask the questions, demand a reason, etc. This is your relationship with the person who is treating you so they would know the nuances of your situation. If it's still not sitting well with you, then get a second opinion.
We really can only give your our anecdotal experience or data that discusses recurrence risks, or you could google risk of DVT recurrence and I'm sure you'd find all kinds of information. But none of us is qualified to evaluate your tests and make a guess at YOUR specific chances of reclotting. That's between you and your doctors.

I am simply looking for a general guide if you will about this situation.
Unfortunately, there's no definitive answer as to who is going to clot again and who isn't. Some people have a high risk for recotting and never do so again, and some people have a low risk for clotting and clot again. If there was no reason for your clot, usually (but not always) the recommendation is to stop warfarin at 3 months, 6 months, a year, whatever the doc's protocol is.
If I upset you, I'm sorry. I was just saying your risk is specific to you and so it's something that your doc or another doc may be able to shed some light on with your case.
1) The cause of the original DVT, i.e. whether it happened "out of the blue" (unknown risk factors or idiopathic) or whether it was caused e.g. by immobility due to cast (known or transient risk factors). The risk of recurrence appear to be greater for idiopathic DVT than transient
2) The extent of damage of the original DVT, e.g. how big was the clot. Whether there is still a residual clot or not. State of the valve veins, degree of swelling and so forth, that have influence on the flow, and on degree of venous return (i.e. back flow through valves)
3) Location of the original clot, proximal versus distal
4) underlying malignancy that can promote clotting e.g. cancer, arthritis and many other diseases .
5) Physical compression of the vein, e.g May Thurner; inflammation
6) Genetic factors that promote clotting or delay lysis of clots
7) lifestyle/general health- obesity/sedative lifestyle...
8) and probably lots of other factors..
These are just several of issues that came to my mind that may influence the decision making of the doctor with regard to continue the anticoagulation treatment or stop it. Many people will never reclot, while some do. There is always a risk of stopping anticoagulaiton treatment, but there is also a risk associated to continue it (e.g. bleeding). The main thing is that the doctor makes a well informed decision based on all the data he/she has available on your case. In the end, no one can say for certain that you will never re-clot sometimes later in your life. However, the doctor may say the probability of getting a clot is smaller than having a bleeding incident and thus is a sensible decision to stop anticoagulaiton.
