All patients with threatened limbs, that was decided upon to have angioplasty will be asked to sign consent form to participate in this study.~Before having the angioplasty, all participants will be examined with ultrasound duplex to determent their common femoral artery volume flow. Day after the angioplasty, they will be reexamined (this is the usual practice) to detriment the new volume flow in the CFA.~The participents examinations in the outpatient clinics will be documented and time for healing will be recorded.
in our study we are examining the volume flow of the common femoral artery before and after angigraphy of a critical ischemic limb, as a predictor for wound healing after the treatment
