However, complications and restenosis rates remain high.<\/jats:p>\n <\/jats:sec>\n \n Objective:<\/jats:title>\n To evaluate the utility of high-resolution C-arm CT (Dyna micro-CT) for stent placement in patients with chronic cerebral artery occlusion.<\/jats:p>\n <\/jats:sec>\n \n Methods and Materials:<\/jats:title>\n We retrospectively reviewed the clinical data of 27 patients with chronic cerebral artery occlusion who underwent mechanical recanalization and stent implantation. Images were reconstructed using conventional C-arm CT (Dyna CT) and Dyna micro-CT. Whether the stent was fully expanded and image quality was evaluated. Follow-up assessments included clinical and angiographic outcomes and complications.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Twenty-two patients successfully underwent stenting (22 stents; 14 cases: Neuroform EZ; eight cases: Enterprise); stenting failed in five patients. Compared to Dyna CT, Dyna micro-CT afforded improved visualization of the stent structure, providing significantly improved image quality (\n P<\/jats:italic>\n < 0.05). In seven patients, the stent under-expanded and dilatation was performed; thereafter, stent malapposition improved. One patient experienced sudden headache 22 hours after the procedure; CT showed intraparenchymal hemorrhage. The remaining 21 patients did not have acute thrombosis or bleeding complications and were followed up by imaging for 3-6 months. In three patients, digital subtraction angiography showed mild in-stent stenosis.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n High-resolution C-arm CT can improve visualization of stent structures in chronic cerebral artery occlusion, making it easy to determine the extent of stent deployment and potentially reduce complications and stent restenosis.<\/jats:p>\n
