Ultrasonography kweenqanawa zobuchopho - ezibonisa ukuba

Kuba abantu abaye baba stroke, kubalulekile ukwenza imithambo yegazi ultrasound yobuchopho, ngokuba icala yi Njengesiphumo esithe ngqo ukuphazamiseka ejikeleza igazi imithambo yegazi. Kubhaliwe ukwenza olu viwo lonyango kuya kunceda ugqirha wakho ukuba ukubonisa ngokuchanekileyo ukuba lingakanani na ithuba isahlakalo kokubetha nezolo. Ultrasound nobeempahla yobuchopho ukuze bachithe njengoko kumiselwe ngugqirha, kwaye kwikliniki ezizodwa sakujika nje. Yaye iziphumo zithetha yincutshe.

Ngaphambi kokuba intloko ultrasound kuyimfuneko ukuba baqhuba uqeqesho. It is a snap, kodwa inika iziphumo oluchanekileyo ngakumbi ultrasonography nobeempahla nedumbe lengqondo. Kwiintsuku ezimbalwa phambi kokuba phando kuyimfuneko ukuba nikhumke ukutya, nto leyo echaphazela uxinzelelo lwegazi. Ayikhuthazwa ukutshaya phambi kokuba ultrasound ubuncinane ngeyure, kodwa kungcono, kakade, ngaphezulu.

Amaxesha amaninzi, izifundo kweenqanawa ingqondo zibanjwa kunye noviwo iimpahla entanyeni. Yiyo le saveyi inika ulwazi olugqityiweyo malunga igazi ingqondo yakhe, njengoko wenziwe ukufunda igazi ngokusebenzisa vertebral kunye subclavian imithambo, imithambo carotid ziphandwa.

Kakuhle eli ultrasound izitya zobuchopho kukuba amaza cuke badlula ngalo igazi iboniswa ngeendlela ezahlukeneyo. Oku kuxhomekeke kubungakanani kunye nezinga krovopotoka ngesitya ethile. Emva koko, amaza ultrasound kubonakala eziguqulelwe kwi pulses zombane kwaye ebekwe kwiskrini. Ngoko ke, ugqirha uyakwazi ukubona ngoko nangoko disorder kobuchopho kwemithambo yobuchopho kwaye ngqo apho kukho exineneyo okanye thrombosis.

Ngelo xesha iimviwo zesiqhelo iinqanawa lengqondo ukumisela patency kuphela. Kodwa izixhobo zisenza sikwazi ukwenza izifundo eneenkcukacha. Umzekelo, ukukrwaqula kabini sele inceda ukuvavanya kuphela isantya sesicatshulwa kwegazi, kodwa ukuze ubone, ukuba bahlole indlela ezakhiwe ngayo iimpahla ngokwabo, yaye ntathu ukukrwaqula ukufumana kwakhona ngqo nokuphononongwa permeability kwemithambo yegazi, nto leyo sekholbheki sibonakaliswa kwimo umbala.

Siphethe UZDG iimpahla intloko entanyeni, unga:

- ukuvavanya Velocity flow igazi imithambo yegazi lasentloko kunye emqaleni;

- ukwenza ubhaqo yokuphazamiseka imithambo yegazi okubangelwa egazi igazi kunye umonakalo atherosclerotic yokuqala;

- iindawo ngokukhomba vasoconstriction ;

- ngokucokisekileyo ngakumbi ukuqonda oonobangela ikhanda njalo;

- ukuze kwenziwe uxilongo yokuqala kwemithambo iimpahla ebuchotsheni.

Xa mabacetyiswe ukuba baqhube izitya Doppler ultrasound intloko:

- ukuba isifundo uye izikhalazo nomonde yintloko rhoqo, ilahleko osezingqondweni, ubukho ingxolo ngaphandle intloko;

- nokuphazamiseka yokuthetha kunye nokuqalisa ngesiquphe ndindisholo iingalo nemilenze;

- ukuba izifo isigulane ezifana lwegazi, sifuba angina, isifo cerebrovascular, seswekile kunye DYSTONIA semithambo , kunye nezinye izifo ezingapheliyo;

- phambi amanqanaba ephakamileyo cholesterol kwaye utyebile, kananjalo xa kuthe yeenguqu ekunqandeni igazi;

- eyenzelwe abantu abaneminyaka engaphezu kwama-40 ubudala, ingakumbi xa izalamane abasondeleyo kuye kwaba namacala omzimba, isifo sentliziyo, yegazi, hypertension;

- le nkqubo iyimfuneko ngexesha lamalungiselelo sesigulane utyando kunye ngempumelelo unyango kakade.

Uviwo kweenqanawa ingqondo yalula kakhulu kwaye kuthatha imizuzu engama-45 kuphela. Ngoko nangoko emva kolu phando isigulana uyakwazi ukuphila ubomi obuqhelekileyo. Emva ekuqhubeni uphando izandla zakho iziphumo banikwa, leyo uyakwazi ukubonakalisa okufihliweyo ugqirha obeqhuba ultrasound, kodwa ngokuqhelekileyo ke baphathwa umntu eyaphuma ulwalathiso ngeenjongo zophando.
