Percutaneous transluminal angioplasty for critical limb ischemia in very elderly diabetic patients.

In diabetic subjects, new less invasive therapies for critical limb ischemia (CLI) are available to obtain limb salvage. One of these is the percutaneous transluminal angioplasty (PTA), a minor surgical intervention which allows obtaining an effective revascularization, avoiding the traditional major surgery and its post-operative complications. Our case report regards a 94-year-old woman with CLI due to critical obstruction (stage IV according to Leriche's classification) of superficial femoral and popliteal arteries and infrapopliteal arteries that should have been treated by the left limb amputation considering her age, severe co-morbidities, and poor compliance. Instead of this quite common approach, our team treated the patient with PTA. This led to very good outcomes, above all in terms of pain control. PTA is able to avoid major surgery, lower intra and post-operative risks, reduce length of hospital stay, and preserve functional autonomy. Therefore, this procedure should be taken into account also for frail very elderly diabetic patients with peripheral artery disease (PAD).
