Cerebral death implies irreversible loss of function of the entire brain, and angiography must therefore include both carotid and both vertebral arteries. Our experience with 21 patients suggests that these acquirements can be met most ... Bücheler, E,Kufer, C,Düx, A - 《Fortschr Röntgenstr...
ResultsThe tortuosity degrees of the left and right vertebral arteries in these patients ranged from 5.1% to 72.6%. The tortuosity degrees of vertebral arteries in patients aged 40-49 years were significantly higher than those in patients aged 20-29 years and 30-39 years ( P<0.05). Correlatio...
