Application of Vaso CT in the recanalization of vertebrobasilar junction occlusion / 中国脑血管病杂志

ABSTRACT

Objective To investigate the risk assessment,guiding role,and clinical value of Vaso CT image features for recanalization of vertebrobasilar junction occlusion. Methods From January 2016 to May 2017,14 patients with vertebrobasilar junction occlusion admitted to the Department of Neurology, Chinese PLA General Hospital were analyzed retrospectively. Preoperative cerebral angiography confirmed vertebrobasilar junction occlusion. Vaso CT was used to measure the length of the occluded vessels and vascular direction at both ends. According to these results, the operative risks were evaluated and the recanalization of vertebrobasilar junction occlusion were guided. Results The length of vertebrobasilar junction occlusion was 2. 56-19. 09 mm (mean 4. 5 ± 2. 1 mm) in 14 patients,and 13 of them were treated with the recanalization of vertebrobasilar artery occlusion,the blood vessels of 12 cases were successfully recanalized and stent placement was performed after the recanalization,among them,8 Solitaire stents and 4 Wingspan stents were implanted;One patient did not perform recanalization because of longer length of occlusion (19. 09 mm). All patients operated did not have any perioperative complications, and the neurological symptoms were significantly improved after procedure. Conclusion Vaso CT can accurately determine the surgical risk of the recanalization of vertebrobasilar junction occlusion,and can guide the surgical pathways,reduce the incidence of perioperative complications,and improve the success rate of the operation.
