I-Doppler yemikhumbi ye-cerebral

Ukuphazamiseka okujikelezayo nokuguqulwa kwamathambo ezitsheni kuholela ezinkingeni ezinkulu zezempilo futhi ngokuvamile kubangela ukushaywa yisifo. Enye yezindlela eziphumelela kakhulu zokuhlola isimo sezitsha zobuchopho zingumdappler (Doppler sonography noma i-doppleroscopy). Le nqubo isekelwe ekuhlaziyweni kwezibonakaliso ze-ultrasonic ezikhiqizwa idivayisi ekhethekile, eziboniswa ezakhiweni zegazi lomuntu.

I-Doppler yokuqondisa kwemithambo yegazi

Ukwenza i-doppler yezimpahla zobuchopho udokotela uyancoma:

1. ikhanda elibuhlungu;
2. isiyezi;
3. ukwephulwa kokuhlanganiswa kokuhamba kanye nemishini imisebenzi;
4. ukunyuka kwengcindezi yokunyuka;
5. i-dystonia yemifino ye-vegetative ;
6. i-pathologies ephikisanayo emkhatsini womzwelo kanye nezinye izimpawu ezinesabekayo.

I-doppler sonography iyasiza ukuxilonga:

• ukulimala kwamathambo (ngisho naseziqaleni zokuqala);
• shintsha ithoni yemikhumbi ye-venous;
• i-stenosis ye-arterial (ukunciphisa);
• ukuphazamiseka egazini, ngokuyinhloko, ukwakheka kwezindwangu zegazi (thrombi);
• ukuthuthukiswa kwe-atherosclerosis;
• ukunyuka kwengcindezi yokunyuka;
• ukuhlukumezeka kwemisipha, kuhlanganise ne- aneurysms .

Inhlangano yenqubo yokuhlolwa

I-Doppler yezimpahla zekhanda - inqubo ayibuhlungu futhi engenabungozi yenziwa njengokuhlolwa kwe-ultrasound. Isiguli silele endaweni ephezulu, kanti ikhanda lifakwa emceleni okhethekile. Ngaphambi kokuba inqubo iqale, indawo ekhanda nentamo okufanele ihlolwe iphathwa nge-gel ehlinzeka ngokuxhumana kangcono kwesikhumba nezinzwa. Inzwa ecindezelwe ngokuqinile ihamba kancane endaweni ethile.

Ngomshini wokucubungula kwengqondo, i-apparatus fixes signals iboniswa kusukela ezindongeni zezimpahla, futhi ibuye isheshe ijubane lamanje igazi. Imishanguzo ye-vertebral, i-carotid ne-subclavia ifakwe ekuhlolweni, okuvumela ukuhlolwa okunembile kwesistimu yesiguli sesiguli.

Namuhla, i-Dopplers enomsebenzi wokuhlaziya, exhunywe ohlelweni lwekhompiyutha, elawulwa yesikrini sokuthinta, isanda ngokubanzi. Ngaphambi kokuqala kwenqubo, isiguli sikwaziswa ngesiguli. Ukuhlaziywa nokuchazwa kwemiphumela kwenziwa ngumchwepheshe. Uma kunesidingo, ukuhlolwa kabusha kungenziwa ukuze kunqume ukuguquguquka kwezinqubo ezenzeka ezitsheni zobuchopho.
