Various pneumatic arterial compression devices have shown evidence that patients with PAD which are not candidates for re-vascularization (arterial bypass) or arterial stent procedures may benefit from treatment with these devices (especially those intolerant to exercise). Research with these devices have reported benefits such as walking distance, leg pain, improved arterial circulation on imaging, and reductions in requirements for amputation. (43,61,62,63)
