Abstract: Objective To investigate the treatment of modified vertebral-carotid transposition (VCT) in patients with severe stenosis or occlusion at V1 segment of vertebral artery. Methods A retrospective study of 13 patients with severe stenosis or occlusion at V1 segment of vertebral artery treated by modified VCT in our hospital from October 2016 to December 2018 was done. There were 10 males and 3 females with an average age of 70.5±7.1 years. Results The operation was successful in this series of patients. The follow-up duration was 1-3 years. The stenosis degree of the V1 segment of the vertebral artery decreased from 86.8%±7.5% to 17.4%±14.5%. All patients achieved remission of symptoms after the surgery. Temporary peripheral nerve injury occurred in 6 patients. Four patients with neurological complications relieved during follow-up. The patency rate was 100.0% at postoperative 1 and 3 years. There was no perioperative death, stroke or re-intervention. Conclusion Modified VCT can precisely restore the distal blood flow of patients with severe stenosis or occlusion at V1 segment of vertebral artery, and relieve their symptoms.
