Indlela yeDoppler isekelwe ekuhlolisweni kweendonga zemigudu yegazi usebenzisa i-ultrasound, i-ultrasound ibonakaliswa kwiiseli ezibomvu zegazi kwaye yenza kube lula ukuhlalutya kwanemibhobho emincinci kunye nemithanjeni. I-Transcranial dopplerography igxininisa ukuqhutyelwa kwe-cerebral circulation ngoncedo lendlela kwaye yenye yeendlela ezincinci, ezifundisayo kunye ezikhawulezayo zokuseka ukuxilongwa.
Yintoni eya kubonisa i-transcranial dopplerography yeenqwelo ze-cerebral?
I-Transcranial dopplerography yeempahla zentloko yenza kube lula ukulandelela le mibala elandelayo:
- ububanzi bemigudu yegazi ephezulu;
- ubude bodonga;
- izinga lokuhamba kwegazi;
- isixa segazi;
- iinkalo ezahlukeneyo zokuchasisa
- i-atherosclerosis kunye neqondo lokunyanzelwa kwalo;
- isigaba kunye nesimo sokuhamba kwegazi;
- ukulinganisa ukuhamba kwegazi ukusuka kumacala athile entloko;
- isivinini se-systolic;
- izinga le stenosis .
Kubalulekile ukuphawula ukuba kwisifundo, ifowuni yokwenza i-dopplerography ibonisa ukunyakaza kwimiba ephambili, yimiba enkulu kunye nemithambo. Iinqanawa ezincinci zeengqondo azikwazi ukufundiswa ngenxa yobuninzi beendonga zekhanga. Iisenjini zifakwe kwiindawo ezincinci-ngaphaya kweelishi, kwiitempile kwaye zingaphantsi kwe-occipital yentloko.
Isizathu sokwenza i-transcranial ultrasonic dopplerography yizinto ezinjalo:
- rhoqo utywala kunye nentloko;
- ukubetha , intliziyo, ukunyuka kwe-thrombosis;
- ukulahleka komsebenzi othile wokuthetha;
- ukubonakala kweempawu eziyimfama kunye nokukhubazeka okubonakalayo;
- ukulahlekelwa kweentetho, ukuvumba nokubona okufanelekileyo iimpawu zengcamango;
- ukudideka kwezikhumbuzo kunye neengcamango;
- ukulahlekelwa kobuchule bokuqhelaniswa kwendawo kunye nokunye okuninzi.
I-transcranial ultrasound Doppler njani?
Inkqubo ye-transcranial dopplerography, okanye i-tkdg, njengoko idla ngokubizwa ngabasebenzi bezonyango, iyinto elula: isigulane siya kucelwa ukuba silale phantsi, i-sonologist iya kuhlala emqaleni entanyeni kwaye ifake i-sensors yefowuni kwindawo efanelekileyo. Ngethuba loviwo, isikhumba siza kugutyungulwa nge-gel ekhethekileyo kwaye siya kutshintshisa iinqwelo. Ngomnye wabo unempawu ezizimeleyo, kufuneka zifakwe, zirekhodwe kwaye zitshekishwe ngokuqhelekileyo kwindawo nganye kwindawo yobuchopho. Ngokuqhelekileyo, yonke ingcaciso ayidluliselwe kwi-neurologist, i-sonologist irekhoda kuphela ezo nkcukacha ezihamba ngaphaya kwesiqhelo. Ngokomyinge, inqubo ithatha ukususela kwimitha engama-30 ukuya kwiyure.
