Abstract
Lower limb angioplasty is commonly performed via antegrade common femoral artery CFA puncture followed by selective superficial femoral artery SFA catheterization Arterial access can be complicated by a “hostile groin” scarring obesity or previous failed CFA puncture We prospectively investigated color duplex ultrasound CDUguided SFA access for radiological interventionsTreatment in 30 patients involved 44 angioplasties 40 transluminal 4 subintimal and 2 diagnostic angiograms Fifteen of these patients had CDUguided CFA punctures in 8 of these patients CDUguided CFA puncture “failed” ie there was failure to pass a guidewire or catheter into the CFA or SFA necessitating immediate direct CDUguided SFA puncture Overall the mean screen time and radiation dosage via direct CDUguided SFA puncture in 30 patients was 48 min and 464 Gy cm2 respectively With CDUguided CFA puncture mean screen time 10 min radiation dose 2023 Gy cm2 and complications 13 were greater when compared with the SFA puncture results overall and in the same patients at subsequent similar procedures 27 min 379 Gy cm2 p 005 no complications in this subgroup Five complications occurred 2 each at CFA and SFA entry sites and 1 angioplasty embolus
