Transcranial color-coded duplex sonography (TCDS) is a noninvasive, quick and inexpensive diagnostic tool used routinely to assess vascular abnormalities in cerebral ischemia. The value of TCDS for diagnosis and follow-up of acute basilar artery (BA) ischemia in comparison/combination with spiral CT angiography (CTA) and/or digital subtraction angiography (DSA) has not yet been studied. We prospectively studied 15 consecutive patients with clinically suspected acute BA occlusion (BAO) by TCDS as well as 3 to 5 d later in those with proven BAO. BA ischemia was verified in 11 patients. During follow-up, all BAO patients showed recanalization of the BA independent of thrombolytic treatment. In conclusion, TCDS appears to be an efficient method for BAO diagnosis when immediate angiography is not available. Together with CTA it increases diagnostic safety before performing an invasive and cost-intensive DSA.
经颅彩色编码双功超声检查（TCDS）是一种无创、快速且廉价的诊断工具，常用于评估脑缺血中的血管异常情况。目前尚未研究TCDS与螺旋CT血管造影（CTA）和/或数字减影血管造影（DSA）相比/联合用于诊断和随访急性基底动脉（BA）缺血的价值。我们前瞻性地研究了15例临床怀疑急性BA闭塞（BAO）的患者，通过TCDS进行检查，并在确诊为BAO的患者中于3至5天后再次检查。11例患者被证实存在BA缺血。在随访期间，所有BAO患者的BA均出现再通，与溶栓治疗无关。总之，当无法立即进行血管造影时，TCDS似乎是诊断BAO的一种有效方法。与CTA一起，它可提高在进行有创且成本高昂的DSA之前的诊断安全性。
