Introduction:

Diabetes mellitus is a distinctive risk factor in peripheral artery disease. This typically produces the involvement of the infragenicular vessels, associated with a greater predisposition to ulceration and amputation than in non-diabetic patients. Due to the bleak outcome of these patients it is necessary to revascularize in order to save the limb.

Objective:

To present a case in which simple angioplasty of the posterior tibial artery was used to save the limb of a diabetic patient.

Case Presentation:

It is presented a case with a diagnosis of infected ischemic diabetic foot in the left lower extremity. On physical examination, infected ischemic lesion was found in the fifth and fourth toes with extension to the back and soles of the foot, and distal steno-occlusive pattern. Decreases in distal pressure indices were detected. Arteriography showed occlusion of the anterior tibial and peroneal arteries from their origin, and steno-occlusive lesions in the posterior tibial in the lower third of the leg. Percutaneous transluminal angioplasty of the posterior tibial was performed and the patient recovered pulse in the posterior tibial with hemodynamic improvement. The patient progressed satisfactorily and was discharged with medical treatment. Five months after surgery, the kept posterior tibial pulse present and the injury healed.

Conclusions:

Simple angioplasty of one of the arteries of the leg can be beneficial for the healing of foot injuries, even if these are extensive.
