Eighty-three patients with intraplaque hemorrhage of the carotid arteries, explored by Duplex scanning, are reported; 36 among them were also studied by digital angiography and 28 were operated on. The echographic aspect suggesting the presence of an intraplaque hemorrhage is that of a hypo-anechogenic stria separating the intimal plaque from the media-adventitia complex. On the contrary, the angiographic findings are aspecific and unrelated to the presence of intramural blood clots. We think that duplex scanning is the investigation of choice in detecting intraplaque hemorrhage of the carotid arteries. The role of other radiological techniques, such as computed tomography of the neck and magnetic resonance, is also discussed.
报告了83例经双功扫描检查发现颈动脉斑块内出血的患者；其中36例还接受了数字血管造影检查，28例接受了手术治疗。提示存在斑块内出血的超声表现是一条低回声条纹，将内膜斑块与中膜-外膜复合体分开。相反，血管造影结果是非特异性的，与壁内血栓的存在无关。我们认为双功扫描是检测颈动脉斑块内出血的首选检查方法。还讨论了其他放射学技术，如颈部计算机断层扫描和磁共振成像的作用。
