A journal article was submitted detailing a retrospective cross-sectional study among patients with in-stent restenosis (isr) in the superficial femoral artery (sfa).257 limbs in 253 patients underwent stent insertion for superficial femoral artery lesions.Medtr onic¿s complete se stent was used during treatment.73 limbs of 73 patients were excluded due to multiple lesion in index vessels, previous stenting history in index vessels and follow-up loss after the procedure.The clinical record of 180 patients (184 limbs) was reviewed.29 limbs in 27 patients diagnosed as in-stent restenosis.14 limbs underwent atherectomy followed by balloon angioplasty.15 limbs underwent balloon angioplasty alone.Medtronic¿s silverhawk atherectomy device was used for atherectomy.One patient in the atherectomy group, and 4 patient¿s in the balloon angioplasty group were treated with an inpact admiral.Technical success was achieved in all patients in both groups, and procedural success was achieved in 85.7% of the atherectomy group, and 73.3% of the angioplasty group, with no significant differences.Clinical events of residual stenosis (treated by repeated balloon angioplasty), distal embolization (treated by aspiration embolectomy), and flow-limiting dissection (treated by bailout stenting) are reported as outcomes following treatment.At one-year follow-up target lesion revascularization was carried out across the two groups.
