Abstract: Objective To retrospectively study the necessity and efficacy of interventional treatment for ischemic cerebrovascular disease associated with non-dominant vertebral artery. Methods Ten patients (including eight males and two females, averaged 52 years old) who were diagnosed as arteriostenosis or dissection were retrospectively studied. All the patients were underwent angiography and the non-dominant vertebral artery was confirmed as the responsible vessel. Results Five Wingspan stents were deployed in four patients and five Apollo stents were deployed in the other four. And two SD stents were deployed in the left two. Six months later, there were two patients were found light in-stent stenosis on DSA (digital subtract angiography). The residual stenosises were absolutely eliminated in eight patients. None of the patients were found with ischemic symptoms. Conclusions Our study suggested that arteriostenosis or dissection in the non-dominant vertebral artery should be treated by stenting. DSA should be performed in non-dominant vertebral artery disease in order to evaluate the potential risk. Treatment or follow up alone should be adopted individually for this kind of patients.
