Is there any correlation between restless leg syndrome and increased risk of blood clots during/after surgery?

I have had restless leg syndrome for most of my life, and the disorder has a lot of similarities/co-morbidity with various vein and nerve diseases, including venous insufficiency. I am scared that this might put me at a higher risk for a blood clot. Are there any parallels between the two things, and is there a way I can assess my vein health/propensity for blood clots before surgery?
