We have investigated 6,380 patients with directional c-w Doppler sonography within the last 3 1/2 years, and have suspected obstruction of the basilar artery or of both distal vertebral arteries in 7 cases. Either bilateral sonographic silence or an absent diastolic flow component of the vertebral arteries were employed as criteria in the sonographic evaluation. Angiography of the vertebro-basilar system, performed in 6 cases, confirmed the diagnoses: basilar artery occlusion was found in 4 patients, 1 patient revealed tight stenosis of the basilar artery in its entire length, and 1 patient exhibited occlusion of both distal vertebral arteries. Three further basilar artery occlusions were detected by means of angiography despite initially negative Doppler sonography within the same period of time; 1 of those patients, however, met the above criteria for basilar artery occlusion upon sonographic reevaluation on the following day. Thus, we believe that directional c-w Doppler sonography is very useful in the diagnosis of basilar artery obstruction.
在过去三年半的时间里，我们使用定向连续波多普勒超声检查了6380例患者，其中7例怀疑存在基底动脉或双侧椎动脉远端阻塞。超声评估标准为双侧超声无血流信号或椎动脉舒张期血流成分缺失。对6例患者进行了椎基底动脉系统血管造影，结果证实了诊断：4例患者发现基底动脉闭塞，1例患者显示基底动脉全长严重狭窄，1例患者双侧椎动脉远端闭塞。在同一时期，尽管最初的多普勒超声检查结果为阴性，但通过血管造影又检测出另外3例基底动脉闭塞；然而，其中1例患者在第二天的超声复查中符合上述基底动脉闭塞标准。因此，我们认为定向连续波多普勒超声检查在基底动脉阻塞的诊断中非常有用。
