Cerebral embolism from cardiac, aortic or carotid cause can be detected by Doppler examination of carotid arteries or transcranial Doppler with long-duration recordings. The signals detected called HITS (high intensity transient signals), which have been described in vitro and in vivo, have specific physical characteristics. This novel technique is considered promising in establishing the relationship between the discovery of embolic heart disease and its clinical neurological manifestations. In the evaluation of a stroke, the detection of HITS could provide evidence in support of an embolic cause. The areas of application of this new technique are many: screening for asymptomatic embolism in patients with an embolic cardiac disorder, and effects of antiplatelet and anticoagulant medications or surgical treatments.
由心脏、主动脉或颈动脉病变引起的脑栓塞可通过对颈动脉进行多普勒检查或长时间记录的经颅多普勒检测出来。检测到的信号称为HITS(高强度瞬态信号),已在体外和体内得到描述,具有特定的物理特征。这种新技术在确立栓塞性心脏病的发现与其临床神经学表现之间的关系方面被认为很有前景。在评估中风时,检测到HITS可为栓塞病因提供支持证据。这项新技术的应用领域众多:对患有栓塞性心脏病的患者进行无症状栓塞筛查,以及抗血小板和抗凝药物或手术治疗的效果评估。
