RESUMO
Objective:To investigate the clinical value of Rotarex ? S in debulking the femoropopliteal calcified lesion. Methods:The data of 5 patients with femoropopliteal calcified lesions treated with Rotarex ? S combined with drug balloon treatment admitted to the First Affiliated Hospital of Dalian Medical University from March 2020 to December 2021 were retrospectively analyzed. The success rate and complications of all operations were recorded. CT software was used to compare the effective lumen area of the target lesion area before and after surgery in all cases, and the ischemic grade of the affected limb before and after surgery was recorded in all patients. Results:All 5 femoropopliteal calcified lesions were successfully treated with Rotarex ? S debulking followed with drug-coated balloon angioplasty without flow-limited dissections, vascular perforation and distal embolizations, with a success rate of 100%. The effective lumen area for calcified lesions were increased 9-15.11 mm 2 (median: 13 mm 2). The Rutherford classifications were improved from R 2-4 to R 1-2. Conclusions:Femoropopliteal calcified lesion debulking with Rotarex ? S was safe and effective.
