Plain uncoated balloon versus drug-coated balloon in the management of in-stent restenosis of femoropopliteal lesions: a comparative study of the effect of lesion length on the outcome

Aim To compare the effectiveness of plain balloon and drug-coated balloon (DCB) in the management of in-stent restenosis (ISR) of femoropopliteal lesions regarding reocclusion rate and target lesion revascularization (TLR). Patients and methods A retrospective study was carried out on 31 patents complaining of critical limb ischemia, Rutherford categories 4 or 5, due to femoropopliteal ISR during the period from June 2018 to June 2020 at Sohag University Hospitals and 6 October Insurance Hospital, Cairo. Patients were managed by one of two different modalities: group A, where patients were managed by DCB, and group B, where patients were managed by plain balloon. In each group, according to the lesion length of the ISR, patients were classified into long lesions (>10 cm) and short lesions (
