I'm assuming that by "DVT" you mean deep venous thrombosis- blood clots in the major veins. Deep venous thrombosis is a potentially life threatening medical emergency. People who believe they have a DVT should seek urgent medical care.
As regards DVT, anticoagulants (used to treat DVT), and diving, Scubadoc has some information at:

The medics found after a long search a very small DVT in my left calf.
I work as a DM when not flying, so the relationship is of interest.
I donot normally suffer from cramps, and recently on one dive had two potential cramp attacks, but managed to eliminate prior to an actual attack.
Three days later flew back home 2h30, lots of leg room. and then after three or four days feld pain in my left leg, just like cramp. My doctor diagnosed cramp, and suggested SALT.
After 4 days of this I visited the Emergency room, and within 3 hours a minor DVT clot was located.
The medication would prevent my professional flying, and it would appear that diving might also be curtailed.....

There is a lot of maybe but there is no concrete evidence regarding DVT and diving that I am aware of.
In your case, I am not sure that cramp can be linked to DVT. Among many causes, if cramp is to be blamed by circulation problem, it is more commonly arterial problem where you would get poor oxygen delivery to your muscle, causing lactic acid build up, usually with exertion of some sort. DVT which happens on the venous side should not cause insufficient oxygen delivery to the muscle. The pain that you get with DVT usually comes with swollen, tender, red leg which is quite different from cramp.
Dehydration, when not corrected from diving certainly could make you more prone to developing DVT afterward, especially when you have a long flight. My guess is that while diving, there should be enough movement of blood to prevent clot formation. Otherwise we probably should hear about marathon runner, ballet dancers getting DVT as well as they do get dehydrated to a certain degree as well. I don't know how much microbubble etc in diving would contribute to DVT however. A very small DVT can be asymptomatic so it is hard to say if it is recent or if it has been there for awhile. Also if diagnose by ultrasound, it can be quite subjective and operator dependent so who knows....
Certainly if you fly a lot, this, in and of itself is a risk for DVT, same go for long distance truck drivers so you would want to try to reduce any risk that you can such as stop smoking if you do, avoid birth control if you can (in case of female), avoid long period of immobility either a quick walk, stretching routine or whatever to avoid stasis of your circulation in the legs, etc...
