Indlela ye-Doppler isekelwe ekutadisheni izindonga zemigudu yegazi usebenzisa i-ultrasound, i-ultrasound ibonakala kumaseli obomvu wegazi futhi yenza kube lula ukuhlaziya ngisho nemithambo emincane nemifino. I-transcranial dopplerography ihlanganisa ukutadisha kwe-cerebral circulation ngosizo lendlela futhi enye yezindlela ezishibhile, ezifundisa futhi ezisheshayo zokusungula ukuxilongwa.
Yini ezobonisa ukuguqulwa kwe-dopplerography yemikhumbi ye-cerebral?
I-transcranial dopplerography yezimpahla zekhanda yenza kube lula ukulandelela izinkomba ezilandelayo:
- ububanzi bemithwalo yegazi esemqoka;
- ubukhulu bodonga;
- izinga lokugeleza kwegazi;
- inani lemibhalo yegazi;
- izimo ezihlukahlukene zokuphikisa - ngokunyakaza, ukuvuthwa kodonga;
- ukuphefumula kwesifo somzimba kanye nezinga lokunganakekelwa kwalo;
- isigaba kanye nemvelo yokugeleza kwegazi;
- ukulinganisa kwegazi kuphuma emaceleni ahlukene ekhanda;
- isivinini se-systolic;
- i- stenosis .
Kumele uqaphele ukuthi esifundweni, idivayisi yokwenza i-dopplerography ibonisa ukunyakaza phakathi kwemithambo emikhulu, kunalokho emikhulu nemithambo. Izitsha ezincane zobuchopho azikwazi ukutadisha ngenxa yobukhulu obukhulu bezindonga ze-skull. Izinzwa zifakwe ezindaweni eziphezulu kakhulu - ngaphezu kwamashiya, kuthempelini futhi ngaphansi kwengxenye ye-occipital yekhanda.
Isizathu sokungena nge-ultrasonic dopplerography yizici ezinjalo:
- ukuzondla njalo kanye nezinsizi;
- ukushaywa yinhliziyo, ukuhlasela kwenhliziyo, ukuhlushwa kwe-thrombosis;
- ukulahlekelwa komunye umsebenzi wokukhuluma;
- ukubukeka kwezindawo eziyimpumputhe nokukhubazeka okubukwayo;
- ukulahlekelwa kokuzwa, iphunga nokubona okwanele izici zokunambitheka kwemikhiqizo;
- ukudideka kwezinkumbulo nemicabango;
- ukulahlekelwa ikhono lokuqondisa emkhathini nokuningi okuningi.
I-transcranial ultrasound Doppler kanjani?
Inqubo yokuguqulwa kwezinto ezidalwa yi-transcranial dopplerography, noma i-tkdg, njengoba ngokuvamile ibizwa ngabasebenzi bezokwelapha, ilula kakhulu: isiguli siyocelwa ukuba silale phansi, lo mntwana uzohlala ngemuva kwentamo yakhe bese efaka izinzwa zedivayisi ezindaweni ezifanele. Ngesikhathi sokuhlolwa, isikhumba sekhanda sizohlanganiswa ngejel ekhethekile futhi kuzoshusha kancane kancane izitsha. Ngamunye wabo unezici zakhe siqu, kumele afakwe, alotshwe futhi ahlolwe ngendlela evamile endaweni ngayinye yobuchopho. Ngokuvamile, lonke ulwazi aludluliselwa ku-neurologist, i-sonologist irekhoda kuphela leyo datha ehamba ngaphezu kwejwayelekile. Ngokwesilinganiso, inqubo ithatha kusukela kumaminithi angu-30 kuya ehoreni.
