Methods: French multicenter retrospective study of all patients treated by in-stent percutaneous mechanical debulking (PMD) of the lower limbs with Rotarex ® S device between January 2013 and November 2018. Results: The cohort consisted of 128 patients (88 men and 40 women), aged 39–94 years (mean, 66.7±12 years). All patients presented with cardio-vascular risk factors. Overall, 51.5% of patients had critical limb ischemia. The study demonstrated a technical success of 96.9% in the population with PMD and adjunctive PTA (95/128, 74.2%) or adjunctive DCB (16/128, 12.5%) or both (13/128, 10.2%). At 12-months follow-up, the primary clinical success/patency rate was 92.3% and the secondary clinical success/patency rate was 91.4%. Rate of limb salvage was 93.7%. Overall 32 (25%) reinterventions were reported with mean time from Rotarex ® S treatment to reintervention of 7.1±8.2 months. Target lesion revascularization (TLR) was 19.5% (25/128). Seven (5.5%) patients developed distal embolism that responded to endovascular treatment. At mean follow-up, major adverse events (MAE) observed were death (18/128, 14.1%), myocardial infarction (MI) (9/128, 7.0%), stroke (2/128, 1.6%) and renal failure (3/128, 2.3%). Conclusions: Recanalization with Rotarex ® S rotational atherectomy plus thrombectomy device is a practical choice for arterial ISR/occlusions of the iliac and/or infrainguinal arteries, regardless of the age of the thrombus, with satisfying TLR. Only adjunctive PTA is often necessary to further improve the recanalization. UR - https://qims.amegroups.org/article/view/33612
