Öğe The usage and efficiency of drugeluting stents in vertebral ostial stenosis(DergiPark, 2021) Erkan, Burcu; Geyik, Serdar; Yavuz, Kıvılcım; Saatci, Işıl; Çekirge, SaruhanObjectives: Extracranial vertebral artery atherosclerosis is an insidious and hazardous disease. With technological development and accumulating experience, antiproliferative drug-eluting stents became a viable option for reducing the in-stent restenosis of the origin of the vertebral artery. Here, we evaluated the technical success rates, efficiency, clinical and angiographic results of the usage of drugeluting stents in vertebral ostial stenosis. Patients and Methods: 28 stents were implanted in 24 patients with vertebral artery origin stenosis. Digital subtraction angiographic or CT angiographic follow-up was made at 6, 12 and 24 months. Results: Paclitaxel-eluting stents were placed with high technical success for the treatment of vertebral artery origin stenosis. There was no procedure-related mortality. However, one patient succumbed to death due to aspiration pneumonia for a basilar artery stroke with successful stenting and thrombolysis procedure. There was only one limited subclavian artery dissection in a patient (%4.1) during the procedure which was managed conservatively. One stent (%3.7) had in-stent restenosis in the early period (6th month) and one patient (%4.1) had recurrent neurological symptoms on follow-up (9th month). In a median follow-up of 13 months (6-25 months), none of the patients had late stent thrombosis. Conclusion: Vertebral artery ostial stenosis can be treated effectively and safely with high technical success and low in-stent restenosis rates with paclitaxel drug-eluting stents. With low restenosis rates, antiproliferative drug-eluting stents are an option for reducing the vertebral artery in-stent restenosis.
