Abstrakt		In the years 1998 and 1999, there were 88 patients (49 males and 39 females) examined in our Laboratory for neurosonology in ordeer to have any possible microembolisms detected. The patients weer distributed according to their referal diagnoses. the velocity of blood flow in both central cerebral arteries was measured by means of transcranial Doppler ultrasonography (Multi-Dop X4, DWL), which enables simultaneous measuring and recording of blood flow velocity and the detection of microemboli in the arteries of the Willisi's circuit. The mean blood flow measurement with emboli detection program was run for hour in each patient. History of ischemic cerebral stroke was stated in 42 patients (30 males and 12 females, mean age 56.9 yrs). Out of 42 patients with ischemic cerebral stroke embokisms were regisytred in 11 (26%) (7 males and 4 females), while 31 patients (74 %)(23 males and 8 females), were without evidence of embolism. All the patients with with ischemic cerebral stroke and positive microemboli had aretiosclerotic changes in the carotid arteries confirmed by ultasonography. History of transient ischemic attack was established in 27 patients (11 males and 17 females), aged 55.1 years. Microembilisms were detected in 15 patients with transient attack (55 %)(6 males and 9 females), while in 12 patients (45 %) (5 males and 7 females) this investigation yielded negative findings. Stenotic changes of varying degree were detected in the carotid arteries of 10 patients with transient ischemic attack. Stenosis of the international carotid artery of varying degree, without evidence of cerebrovascular disease was established in 7 persons under study (6 males and 1 female), aged 63.27 years. In this group of patients emboli were detected in 3 males (43%), with ultrasonographic evidence. Asymptomatic fibrilation of the atria was found in 9 patients aged 50.4 years. Emboli were detected in 2 females (22%), while in 5 females and 2 males they were not registred.
Izvleček		V letu 1988 in 1999 smo v Ambulanti za nevrosonologijo pregledali 88 bolnikov (49 moških in 39 žensk) z nemenom, da bi zaznali morebitne mikroembolizme. Razdelili smo jih glede ne napotne diagnoze s transkrenialno Dopplarjevo ultrasonografijo (Multi-Dop X4, DWL), ki omogoča beleženje hitrosti krvi in zaznavanja mikroembolizmov v arterijah Willisijevega obroča. Srednjo hitrost krvi s programom za zaznavanje embolov smo pri vsakem preiskovancu merili eno uro. Ishemično možgansko kep je prebolelo 42 bolnikov, od tega 30 moških in 12 žensk, povprečna starosti 58,9 let. Izmed 42 bolnikov z ishemično možgansko kapjo smo registrirali embolizme pri 11 (26 %) (7 moških in 4 ženskah), medtem ko pri 31 bolnikih (74 %) (23 moških in 8 ženskah) nismo zaznali nobenega embola. Vsi bolniki z ishemično možgansko kapjo in pozitivnimi mikroemboli so imeli ultrazvočno dokazane aterosklerotične spremembe v karotidnih arterijah. Prehodni ishemični napad je prebolelo 27 bolnikov (11 moških in 17 žensk), starih 55,1 let. Mikroembolizme smo zaznali pri 15 bolnikih s prehodnim ishemičnim napadom (55 %) (6 moških in 9 ženskah), pri 12 bolnikih (45 %) (5 moških in 7 ženskah) pa je bila preiskava negativna. Pri 10 bolnikih s prehodnim ishemičnim napadom smo odkrili zožitvene spremembe višje stopnje v kerotidnih arterijeh. Zožitev notranje kerotidne arterije rezlične stopnje brez znakov možganskožilne bolezni smo ugotovili pri 7 merjencih (6 moških in 1 ženski), starih 63,27 let. Embole v tej skupini bolnikov smo zeznali pri 3 moških (43 %), ki so imeli ultrezvočno dokazano hemodinamsko pomembno (več kot 70 %) zožitev notranje karotidne arterije, medtem ko jih pri 3 moških in 1 ženski nismo registrirali. Asimptomatsko fibrilacijo atrijev je imelo 9 bolnikov, starih 50,4 let. Embole smo zaznali pri 2 ženskah (22 %), pri 5 ženskah in 2 moških pe jih nismo registrirali.
