Remote Superficial Femoral Endarterectomy: Long-term Results

Abstract

Purpose The aim of this study was to determine long-term results following successful remote superficial femoral endarterectomy (RSFE). Methods RSFE is a minimally invasive technique of revascularising the superficial femoral artery. A single incision was made over the origin of the superficial femoral artery. The endarterectomy was carried out in a closed fashion from above. The cut end of distal atheroma was secured with a stent. Following RSFE patients were followed up with intravenous digital subtraction angiography (IVDSA) and 3-monthly duplex scans. IVDSA was repeated if any abnormality was found. Results RSFE was attempted on 30 patients with 33 symptomatic legs to treat tissue loss ( n=3), rest pain ( n=3) or intermittent claudication ( n=27). In 26 limbs it was possible to complete the RSFE satisfactorily (technical success 79%), but during follow-up 18 later developed stenoses. Of 31 stenoses detected, 27 were treated by angioplasty. Primary patency at 1, 2 and 5 years was 38, 31 and 16%, respectively. Primary-assisted patency at 1, 2 and 5 years was 77, 65 and 60%. Conclusions Primary-assisted patency following RSFE is reasonable, however, it is only achieved with life-long surveillance and intervention. Until results can be improved the widespread use of RSFE cannot be recommended.
