Methods The risk factors, clinic and radiological features, and functional outcomes were assessed in 18 patients with posterior circulation ischemia whose basilar arteries were not completely visualized on MRA. The total of 11 males and 7 females, aged 43 to 80 years with a mean year of 64.8. Results Out of 18 patients included, 14 patients （77.8% ）had a history of hypertension, 13 （72.2% ） of cerebral infarction, 9 （50.0% ）of heart diseases. The admission NIHSS scores were (12.11±6.92). The admission GCS score
