Is Exilis Safe and Successful for Calf Fat/size Reduction? Can It Cause a DVT?

I have never had a dvt but almost everyone else in my family has. Can Exilis cause or contribute risk for DVT if done on the leg? Also, I have abnormally large calves from genetics and playing sports in high school and then gaining weight as I have aged. Has Exilis shown safe effectiveness in reducing calf circumference?
