PAD may be one of the most frequently undetected, chronic, debilitating disorders, and it is certainly the most frequently unrecognized atherosclerotic cardiovascular disease. This retrospective study included 40 patients presented to the vascular surgery department in Kasr Al Aini and New Kasr Al Aini teaching hospitals with critical chronic lower limb ischemia for whom percutaneous transluminal angioplasty was done, between January 2008 and January 2010. The aim of the study is to evaluate the effectivness of infrapopliteal angioplasty in limb salvage in critical limb ischemia. The plan was that in all patients with gangrene or severe infection we try to revascularize as much tibial vessels as possible. For every patient, the following data were recorded : Indications of the procedure, Risk factors i.e. diabetic, cardiac, hypertensive and renal failure, Access method, Type of the guide wire, size of balloon (diameter and length), Indication for stenting if needed, Size of the stent. Our results showed 38 cases immediate success and after 3 months only 31 remained patent and after 6 months 25 remained patent. Of the 25 patients who presented with nonhaling ulcers, 24 had successful angioplasty and healed within 8-10 weeks after the successful angioplasty. At the time of complete healing only 19 had the angioplastied tibial vessel still patent and one case of unsuccessful angioplasty who did not heal but remained stable ulcer. The 15 patients who presented with gangrene:, 13 cases had successful angioplasty and underwent minor amputations after successful angioplasty and the amputation stumps healed in (3) months average. At the time of complete healing only (9) cases had the angioplastied tibial vessel still patent. One case of unsuccessful angioplasty who did below the knee amputation. Endovascular therapy is increasingly becoming a first-line treatment option for patients suffering from critical limb ischemia from infrapopliteal arterial occlusive disease by easily revascularizing inflow and outflow lesions with minimal morbidity and mortality. It has the ability to significantly improve distal extremity perfusion pressure with high technical success rates.
