Abstrakt     It is known today that the causes of the ishaemic stroke are mostly extracranial. The most common sources of emboli are the heart, the aorta and big cerebral arteries. Doppler ultrasound signals of high specter, detected by means of Transcranial Doppler Sonography (TCD) during heart surgery and later during carotid endarteriectomy, neuroradiological investigations and in open foramen ovale diagnostics, were first reported in the sixties. In 1993, during the 15th World Congress of Neurology, the term HITS (high intensity transient sygnals) was introduced to describe all the Doppler phenomena that carry the characteristics of emboli. It wasn't until 1998 that the international agreement regarding detectionof microemboli with the use of TCD was finaly issued to be used by all the neurosonologic labs around the world. The article presents the recommendations of this agreement and the results of clinical studies originating from different medical fieldswhere the usefulness and advantages of detection of emboli with the use of TDC have been evaluated. All these studies show that the detection of emboli by means of TCD represents a new technique which, uncovering the source and nature of emboli and thus enabling the ishemic stroke prevention and suitable therapeutic agrement, promises a revolution.
Izvleček     Danes je znano, da je vzrok za ishemično možgansko kap večinoma izven lobanje. Najpogostejši izvor embolizmov so srce, aorta ali velike možganske arterije. V šestdesetih letih so prvič poročali o ultrazvočnih dopplerskih signalih visokega spektra, ki so ji zaznali s pomočjo transkranialne Dopplerjeve sonografije (TCD) med srčno operacijo, kasneje pa med karotidno endarterektomijo, med nevroradiološkimi preiskavami in v diagnostiki odprtega ovalnega okna. Na 15. svetovnem nevrološkem kongresu leta 1993 so sklenili, da bodo te dopplerske fenomene, ki imajo lastnosti embolov, poimenovali HITS (angl.high intensity transient signals). Šele leta 1998 je bilo objavljeno mednarodno soglasje zaznavanja mikroembolov s TCD, ki naj bi ga upoštevali vsi nevrosonološki laboratoriji po svetu. V članku so navedena priporočila tega soglasja in rezultati kliničnih študij iz različnih kliničnih področij, kjer so ugotavljali uporabnost in koristnost tehnike zaznavanja embolov s TCD. Vse študije so pokazale, da je zaznavanje embolov s TCD nova tehnika, ki obljublja revolucijo v diagnostiki odkrivanja izvora in vrste embolov ter s tem omogoča preprečevanje ishemične možganske kapi in pomoč pri odločitvah o zdravljenju.
