[Study of BAEP, TCD and neck rotation test in vertebrobasilar-artery insufficiency patients].
Forty patients with vertebrobasilar-artery insufficiency(VBI) were checked by BAEP and BAEP together with neck-rotation test. Their positive rates were compared with those of TCD. The results showed that: 1. the positive rate of BAEP was 50%, lower than that of TCD; 2. after neck rotation test, the positive rate of BAEP increased from 50% to 86.3%. The results suggest that BAEP together with neck rotation test can obviously increase the positive rate of BAEP. The method is simple and effective in clinical application.
