Ngisho nasekudlulile kwamuva, izitsha zekhanda nentamo azifinyeleleki ukuphenywa, ngoba Ngezicubu zethambo le-skull azizange zidlule izimpawu. Njengamanje, lokhu kungenzeka, ngenxa yokusungulwa kwendlela yokuxilonga ye-ultrasound dopplerography (UZDG), okwamanje iyindlela ehamba phambili yokuhlolwa kwanoma yiziphi izifo ezihambisana nokugeleza kwegazi okungenakukhubazeka ekhanda nentamo.
Lapho kubalulekile ukufeza i-ultrasound yezinto ezisekhanda nentamo?
Izinkomba ze-UZDG zezimpahla zekhanda nentamo:
- ukuzondwa, ukuphelelwa amandla;
- i-migraines;
- umsindo ezindlebeni , ukungahambisani nokuhamba;
- ukuphazamiseka kokulala, ukukhathala;
- ukuxhaswa kwabantu;
- i-dystonia yemifino yemvelo;
- izimpawu zokuphazamiseka kwe-cerebral circulation
- ukusola kokuphazamiseka kokujikeleza ematendeni emgodini wesibeletho;
- ukungajwayelekile kwezimpahla zesisekelo sobuchopho, njll.
Iyini i-ultrasound yezingubo zekhanda nentamo?
I-UZDG iyindlela yokuxilonga esebenzisa indlela ye-ultrasound ihlangene ne-Doppler. I-Dopplerography ikuvumela ukuba uqaphe ukuhamba kwegazi ngokusebenzisa izitsha zekhanda nentamo futhi ngokufanayo ukubona izinkinga ezihlukahlukene zokugeleza kwegazi.
Indlela yokwenza ucwaningo isekelwe kulokho okuthiwa i-Doppler effect. Lo mphumela ubonakala ngale ndlela: isignali etholakele inzwa ekhethekile ibonakala kumaseli egazi. Ukuvama kwesignali kunquma izinga lokugeleza kwegazi. Ngemuva kokuthola ushintsho kumvamisa wesignali, idatha ifakwe kwikhompyutha lapho isimo sezitsha nezinkinga eziba nazo kunqunywe khona ngezibalo ezikhethekile zezibalo.
Yini ekhombisa izitsha ze-UZDG zekhanda nentamo?
Le ndlela ihlanganisa ukuxilongwa kwe-subclavia kanye ne-vertebral arteries, i-carotid arteries, kanye nemithambo emikhulu ebuchosheni.
I-ultrasonic dopplerography inganquma:
- ukugeleza kwegazi ukuhamba nge-arterium main of the head and neck;
- izinga lokushintsha kwe-atherosclerotic ezitsheni;
- i-stenosis yemithambo yegazi;
- ukuguqula ukugeleza kwegazi eduze kwemithambo ye-vertebral e- osteochondrosis ;
- ukutholakala kwe-aneurysm yemikhumbi ye-cerebral.
Ukuze kuchazwe izinkomba ze-USDG zezitsha entanyeni nasekhanda, kubalulekile ukuthi ube nokuqeqeshwa okukhethekile. Ngakho-ke, udokotela oqeqeshiwe kuphela ozokwazi ukucacisa ukuthi kukhona yini ukwehlukana okuvela kumkhuba, ngokusho kwemiphumela ye-ultrasound yemishini entanyeni nasekhanda.
I-UZDG iqhutshwa kanjani ezitsheni zentanyeni nekhanda?
Ukuze ufunde indlela ye-ultrasound yezinto ezisekhanda nentamo, asikho isidingo sokuqeqeshwa okukhethekile. Le nqubo ayinabungozi ngokuphelele futhi ayinabuhlungu, ayinayo imiphumela emibi, imithwalo yemisebe kanye nokuphikisana.
Phakathi nesifundo, isiguli silele embhedeni ngekhanda eliphakanyisiwe. Inzwa ekhethekile isetshenziselwa amaphuzu athile ekhanda nasentanyeni (ezindaweni lapho izitsha ezihlolwayo ziseduze nomzwa). Ukuhambisa kancane kancane inzwa, isazi sihlaziya isithombe esimweni sokuqapha ikhompyutha, esinikeza isithombe esiphelele semithini yegazi negazi kuzo. Inqubo ihlala cishe isigamu sehora.
Kukuphi ukudlula izitsha ze-UZDG entanyeni nasekhanda?
Ngeshwa, akuzona zonke izikhungo zokwelashwa ezihlomele amadivayisi we-ultrasonic dopplerography. Futhi izindleko ze-ultrasound zezitsha zentanyeni nekhanda ziphakeme kakhulu. Kumele futhi kuqashelwe ukuthi ukuziphatha kahle kwenqubo yokuhlola nokuhumusha imiphumela kungenzeka kuphela ngezinga eliphakeme lokuqeqeshwa kwabasebenzi bezokwelapha. Ngakho-ke, kunconywa ukuthi uqhube uphenyo kuphela kulezo mitholampilo ezihlonyelwe ubuchwepheshe besimanje, futhi lapho ungahlinzeka khona izitifiketi eziqinisekisa iziqu zabachwepheshe.
