Color-coded Doppler sonography of the vertebral arteries was performed in
86 patients who had a history of vertebrobasilar disease. The origin of the
artery was visualized in 87.2% on the right and 70.9% on the left side. The
inter-transverse portion of the vertebral artery was visualized in 95% on
the right and 97% on the left side. The atlas loop could be visualized in
88.4% on the right and 84.9% on the left side. Pathologic findings were
hypoplasia (n = 4), stenosis (n = 19), dissection (n = 2), occlusion (n =
7), kinking (n = 12), cervical tumors (n = 3), and subclavian steal
syndrome (n = 3). Nine postoperative patients had subclavian and vertebral
artery reimplantation to the common carotid artery. The characteristic
color-coded Doppler sonographic features of these findings are presented
and discussed.
