Abstract
Objective: Rotational thrombectomy using a Rotarex S device aids the removal of organised thrombus and soft atherosclerotic material in complex femoropopliteal lesions. The aim of this study was to assess the safety and efficacy of the Rotarex S device in combination with drug coated balloon (DCB) angioplasty for the treatment of in stent re-stenosis (ISR).
Methods: Rotarex S (Straub Medical) was used in combination with DCB for the treatment of patients with lower limb ISR and stent occlusions (Tasaka II or III) who presented with subacute or chronic symptoms. Primary endpoints were freedom from clinically driven target lesion revascularisation (CD-TLR) and patency at 12 month follow up. The secondary procedural endpoint was procedural success. Secondary safety endpoints were perforation and peripheral embolisation.
Results: Between January 2017 and August 2023, 215 consecutive patients were enrolled, comprising 84 (39.1%) with claudication, 79 (36.7%) with ischaemic rest pain, and 52 (24.2%) with ischaemic ulcerations due to femoropopliteal lesions (popliteal artery involved in 42.8% of cases). The median patient age was 73.0 years (interquartile range [IQR] 68.0, 77.0), 59.1% were male, and 44.7% had diabetes mellitus. Tosaka III lesions (total occlusions) were present in 165 patients (76.7%). Median lesion length was 22.0 cm (IQR 17.0, 27.0). No perforations occurred, whereas three (1.4%) peripheral embolisations were noted (all three observed with subacute presentation and total stent occlusion). All complications were treated within the index procedure by manual catheter aspiration without requiring surgery or lysis. After one year, 28 patients (13.0%) underwent CD-TLR, whereas primary patency was present in 156 patients (79.2%).
Conclusion: Rotarex S thrombectomy can be used safely for debulking and removal of organised thrombus in subacute and chronic ISR lesions and occlusions. Additional DCB after debulking provides clinically acceptable CD-TLR and patency rates in this complex patient cohort.
期刊介绍：
The European Journal of Vascular and Endovascular Surgery is aimed primarily at vascular surgeons dealing with patients with arterial, venous and lymphatic diseases. Contributions are included on the diagnosis, investigation and management of these vascular disorders. Papers that consider the technical aspects of vascular surgery are encouraged, and the journal includes invited state-of-the-art articles.
Reflecting the increasing importance of endovascular techniques in the management of vascular diseases and the value of closer collaboration between the vascular surgeon and the vascular radiologist, the journal has now extended its scope to encompass the growing number of contributions from this exciting field. Articles describing endovascular method and their critical evaluation are included, as well as reports on the emerging technology associated with this field.
