Abstract：Objective To investigate the surgical strategy for patients with severe stenosis at the origins of the internal carotid and vertebral arteries (OICVA). Methods Clinical data of 106 patients with severe stenosis at OICVA were analyzed retrospectively. Eighty-seven patients were treated by one-stage operation of vertebral angioplasty and stenting ( VAS ) and carotid angioplasty and stenting (CAS), and 19 patients were treated by two-stage operation of angioplasty and stenting followed by carotid endarterectomy (CEA), including VAS followed by CEA in 11 patients, VAS and CAS followed by CEA in 5, and bilateral VAS followed by CEA in 3. Results Good artery morphology, smooth blood flow and improved cerebral perfusion were achieved in all the patients based on DSA and MRI perfusion reexamination after the operation. Petechial cerebellum infarction occurred in 5 patients during perioperative period, and all the patients recovered after conventional medical treatment. During a follow-up period of 6 to 48 months, cerebral infarction occurred in 3 patients, restenosis after VAS in 14 and restenosis after CAS in 5, while no patient underwent restenosis after CEA. Conclusion The surgical method of VAS, CAS and CEA can flexibly apply to severe stenosis at OICVA, and can reduce postoperative complication.
