Six (6) presented disabling claudication and 13 critical ischemia withadvanced distal trophic lesions in 5. A good arteriographic result was obtained in 12 cases, a stent wasplaced on the superficial femoral artery in 5 due to suboptimal outcome. Contrast extravasation wasobserved in 2, with femoropopliteal bypass performed and one exclusion with endoprosthesis for repair.In the ecodoppler after 1, 3, 6 and 12 months, a progressive reduction in lumen diameter and peakintraarterial systolic velocity was observed, particularly on the distal superficial femoral artery. Afterone year, 7 patients (36.8%) were symptom-free, 5 (26.3%) presented mild or moderate intermittentclaudication and 1 patient (5.3%) presented localised distal trophic lesion. Four (4) major amputationswere performed, in 2 the knee was preserved, there were 3 thromboses due to the procedure, a secondaryendovascular procedure was performed in one case and a femoropopliteal bypass in another, and therewere 2 non procedure-related deaths.Discussion: atherectomy with SilverHawk achieves an improvement in clinical degree, with a good rateof extremity salvage in patients with critical ischemia. In the first year, the ecodoppler shows evolutionof the arteriopathy, without this necessarily meaning a clinical worsening. PB Universidad de Valladolid.
