Over the last few years, many authors have described the possibility of using transcranial Doppler to demonstrate the passage of microemboli in the cerebral arteries. We report the case of a 44-year-old woman with thrombotic diathesis and thrombocytosis who was admitted twice within a short period of time (one and a half months) to a neurological department because of multiple cerebral infarctions. On the occasion of the second admission, a colour-Doppler examination of the epiaortic vessels, which had previously been negative, showed a carotid lesion due to a mural thrombus and, on the same side as the carotid lesion, transcranial Doppler detected short-duration, high-intensity signals in the middle and anterior cerebral arteries, an expression of the passage of microemboli. As already described by other authors in similar clinical situations, our case confirms that transcranial Doppler can identify the passage of microemboli in the circle of Willis.
在过去几年中，许多作者描述了使用经颅多普勒来证明微栓子在脑动脉中通过的可能性。我们报告了一名44岁患有血栓形成素质和血小板增多症的女性病例，该患者在短时间内（一个半月）因多发性脑梗死两次入住神经科。在第二次入院时，对之前检查结果为阴性的主动脉弓血管进行彩色多普勒检查，发现由于壁血栓形成导致颈动脉病变，并且在与颈动脉病变同侧的大脑中动脉和大脑前动脉中，经颅多普勒检测到短持续时间、高强度信号，这是微栓子通过的表现。正如其他作者在类似临床情况下所描述的那样，我们的病例证实经颅多普勒可以识别 Willis 环中微栓子的通过情况。
