ABSTRACT
PURPOSE:
The aim of this study was to assess the efficacy and safety of the novel SLR (SELUTION sustained-limus-release) drug-coated balloon (DCB) in the treatment of the femoropopliteal steno-occlusive disease. MATERIALS ANDMETHODS:
From February 2021 to March 2022, 80 consecutive patients (age 69.5±8.23 years; total number of lesions 80) with a steno-occlusive lesion of superficial femoral artery were enrolled at our center. A total of 60 patients (75%) had claudication, whereas 20 (25%) had chronic limb-threatening ischemia (CLTI). The mean lesion length was 171±82.22 mm. The primary efficacy outcome was primary patency at 12 months, defined as freedom from restenosis determined by a duplex ultrasound peak systolic velocity ratio ≤2.4. The secondary efficacy outcome was freedom from clinically-driven target lesion revascularization (CD-TLR) at 12 months. The primary safety outcome was a composite of freedom from device- and procedure-related mortality, major target limb amputation, and clinically-driven target lesion urgent revascularization (endovascular or bypass graft) at 30 days and 12 months.RESULTS:
Device success was achieved in all 80 patients. One death on day 7 from cardiovascular complications was ruled procedure-related because it occurred within the first 30 days from the discharge. Two patients with CLTI experienced planned minor amputations of target limb, and one patient underwent urgent bypass graft of the target vessel for early occlusion at 60 days from the index procedure. The primary safety outcome was 98.7% and 97.5% at 30 days and 12 months, respectively. At 1 year, primary patency was 86.3%, and freedom from CD-TLR was 96.2%.CONCLUSION:
These findings suggest that using a novel sirolimus-coated balloon is a safe and effective treatment option for femoropopliteal steno-occlusive lesions in a variety of clinical and anatomical settings. These results will need to be confirmed by long-term follow-up and randomized controlled trials. CLINICAL IMPACT In femoropopliteal steno-occlusive lesions paclitaxel drug-coated devices have been proved to be able to achieve a better vessel patency during follow-up compared with uncoated balloon, but according to a recent meta-analysis they may carry an elevated risk of late mortality. Sirolimus results in a wider therapeutic range with a 3-fold higher margin of safety. Sirolimus coated devices have recently been proposed as an alternative. This study suggests that using a novel sirolimus-coated balloon is a safe and effective treatment option for femoropopliteal steno-occlusive lesions.
