Veins only Vascular Practice

Curious now, can one create a vascular surgery practice solely focusing on venous insufficiency / varicose veins and AV access? I'm talking just doing VNUS and AV accesses....no artery stuff. Seems too good to be true. Making bank (doesn't vein pay more than arterial anyway) and having essentially no call whatsoever.
