Background: The outcome of acute ischaemic stroke due to tandem vertebrobasilar artery occlusion was poor. Endovascular revascularisation may be a positive approach for acute basilar artery occlusion combined with vertebral ostium stenosis or occlusion. We reported seven patients with acute vertebrobasilar tandem occlusion by using angioplasty or stenting for proximal lesion and thrombectomy for distal occlusion.
Materials and methods: Consecutive patients with acute tandem vertebrobasilar artery occlusion at two centres were included in this study. We retrospectively analysed the clinical, technical and functional outcomes of the patients.
Results: From March 2016 to March 2017, seven patients were included. The mean age and National Institute of Health Stroke Scale score at admission was 57 years and 22, respectively. A reverse approach was used in five patients. The Thrombolysis in Cerebral Infarction score 2b-3 was acquired in all patients. There were no procedural complications. The modified Rankin Scale score was 1-2 for three patients and 4 for one patient at 3 months. Three patients died at 3 months of follow-up.
Conclusions: Endovascular revascularisation may be feasible for acute tandem vertebrobasilar artery occlusion, and more researches are needed.
