Purpose The present study aimed to determine the safety and efficacy of a drug-coated balloon inflated within a thin-strut self-expanding bare-metal stent in patients with severe and complex femoropopliteal occlusive disease. Methods This prospective study used the Pulsar-self-expanding stent and Passeo-18 Lux drug-coated balloon in patients with severe and complex femoropopliteal occlusive dis...

The mechanical behavior of aortic stent grafts plays an important role in the success of endovascular surgery for aneurysms. In this study, finite element analysis was carried out to simulate the expansion of five marketed stent graft iliac limbs and to evaluate quantitatively their mechanical performances. The deployment was modeled in a simplified manner according to the following steps: (i) ...

Open stent grafting is an alternative treatment for extensive thoracic aortic replacement. However, this procedure is associated with a high incidence of spinal cord injury, which has limited its application. Multiple factors have been suggested to explain the risk of spinal cord injury, including deep delivery of the stent graft, history of operation of the downstream aorta, and postoperative ...

Giant-cell arteritis is associated with a higher risk of aortic aneurysm and aortic dissection formation. We present a women with aortic dissection type B treated with a stent graft and bare-metal stent implantation. After the stent deployment we noticed aortic rupture, which was successfully treated with implantation of an additional stent graft. This report highlights the difficulty of endova...

OBJECTIVE Our objective was to assess potential causative factors of stent-graft collapse after thoracic endovascular aortic repair. METHODS We retrospectively reviewed clinical data and preoperative and postoperative computed tomographic scans of patients with thoracic stent-graft collapse in 2 French departments of vascular surgery. Aortic arch angulation, length of the lack of device wall ...

BACKGROUND Recently, thoracic aortic stent grafting has emerged as an alternative therapeutic modality for patients with thoracic aortic aneurysms and aortic dissections. However, its application has been limited to descending thoracic aortic aneurysms distal to the aortic arch. We report our initial clinical experience of endovascular branched stent graft repair for aortic arch aneurysms. ME...

Background—Treatment of in-stent restenosis with paclitaxel-coated balloon catheter as compared with plain balloon angioplasty has shown surprisingly low late lumen loss at 6 months and fewer major adverse cardiac events up to 2 years. We compared the efficacy and safety of a paclitaxel-coated balloon with a paclitaxel-eluting stent as the current standard of care. Methods and Results—One hundr...

background: recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. in this study a unique radioactive source for intra vascular brachytherapy (ivbt) was investigated. the two-dimensional dose distribution in water for a 32p ivbt stent has been calculated. the pure beta emitter source 32p has been coated on p...

Abstract Minimally invasive therapies using stent technology are currently limited by stent-induced granulation tissue formation adjacent to the stent. The effectiveness of photothermal therapy (PTT) a gold nanoparticle (AuNP)-coated for treating in rat esophagus was investigated. All experiments were approved animal research committee our institution. An AuNP-coated, self-expandable metallic (...
