Materials and Methods 28 patients, 32 affected limbs with diabetic foot underwent angioplasty. The balloon diameter is 1.5 mm -6 mm,with length 60 -120 mm and pressure 10 - 17bar. The patients with artery of lower pepliteal artery were treated by PTA. We observed the size of ulcer,purulent secretion, granulation of raw surface and arteriopalmus of dorsal pedal artery in order to evaluate the revascularization during operation, Results The technical successful rate was 100% with no complication occurred. The symptoms were relieved in all patients after treatment, including promotion of lower extremity arterialblood perfusion, reducing range of ampulation and wound healing after amputation. Conclusion PTA shows safe and good clinical result and ought to be recommended in treating diabetic patients with peripheral arterial diseases, especially the lower extremity ischemia.
