RESUMO
Objective To evaluate percutaneous transluminal angioplasty ( PTA) for stenosed arteries of the lower extremities in patients with ischaemic diabetic foot. Methods We retrospectively analyzed the clinical and follow-up data of using PTA to treat diseased infrapopliteal arteries in diabetic patients who were hospitalized from Oct,2006 to May,2008. Results Technical success rate was 87% , procedure related complications developed in 8. 9% of patients, postoperative complications were 11. 1% , perioperative mortality was 2. 5% , limb salvage rate was 90% , pain symptom was significantly mitigated or relieved, ulcer healed well. The median hospitalstay was 10 days. Restenosis rates were 38. 1 % , 50% respectively at 1 year and 2 years. Rest pain and ulcer recurrence rates were 10% and 12% at 1 year and 2 years respectively; Amputation rates were 10% and 15. 3% at 1 year and 2 years. Restenosis ( or occlusion) , rest pain or ulcer recurrence and amputation rate in Fontain Ⅳ group is significantly poorer than that in Fontain Ⅰ - Ⅲ group (P ＜0. 05). Conclusions Percutaneous transluminal angioplasty (PTA) for critical limb ischeamia in patients with ischaemic diabetic foot are feasible, with minimal invasiveness, low complications. Fontain classification predicts PTA thrapeutic results.
