Xa ugqirha ekucela ukuba wenze iskeni, ngamanye amaxesha uziva usoyika kwaye unomdla, akunjalo? Ingakumbi xa ekucela ukuba wenze "iDoppler Ultrasound", igama lingaqhelekanga kwaye unokuzibuza ukuba yintoni le. Kodwa akukho sizathu sokoyika. Olu luvavanyo olulula kakhulu, olungenabuhlungu, nolukhuselekileyo kakhulu. Masithethe ngayo yonke into ngendlela elula kakhulu namhlanje.
Ngamafutshane, yintoni le Doppler ultrasound?
Cinga ngemithambo yegazi emzimbeni wakho njengeendlela. Igazi lifana nezithuthi ezihamba kwezi ndlela. Ngoko ke, bekuya kuba kuhle kangakanani ukuba bekukho indlela yokubona ukuba ezi zithuthi zihamba kakuhle na, ukuba zibambeke kwingxinano yezithuthi, ukuba zihamba ngokukhawuleza kakhulu, okanye ukuba zihamba kancinci kakhulu? Yiloo nto eyenziwa lolu vavanyo lwe-Doppler ultrasound.
Oku kusebenzisa amaza esandi ukwenza imifanekiso yegazi elihamba ngemithambo yegazi yakho. Le mifanekiso ingabonisa ngokucacileyo isantya kunye necala lokuhamba kwegazi ngemithambo yegazi yakho (imithambo yegazi kunye nemithambo yegazi), kunye nendlela igazi elihamba ngayo entliziyweni yakho.
I-ultrasound scan rhoqo ithatha umfanekiso welungu (umz. izintso, isibindi). Nangona kunjalo, i-Doppler scan inokujonga iinkcukacha zegazi elihamba ngaphakathi kwelo lungu okanye ngaphakathi kwemithambo yegazi. Lowo ngumahluko omkhulu phakathi kwezi zimbini.
Zingaphi iintlobo zeDoppler ultrasound ezikhoyo?
Ewe, kukho iintlobo ezahlukeneyo zeeDoppler scans ezisetyenziswa ngoogqirha kuxhomekeke kwimfuneko yazo. Akufuneki ucinge kakhulu ngezi, kodwa kulungile ukwazi okuncinci.
| Uhlobo lokuskena | Kwenzeka ntoni ngale nto? |
|---|---|
| I-Doppler yoMbala | Kule meko, ikhompyutha isebenzisa imibala eyahlukeneyo ukubonisa icala lokuhamba kwegazi. Umzekelo, igazi elihamba kwelinye icala linokuboniswa ngombala obomvu, kwaye igazi elihamba kwelinye icala linokubonakala ngombala oluhlaza okwesibhakabhaka. |
| I-Spectral Doppler | Ipateni yokuhamba kwegazi iboniswa njengegrafu. Oku kukuvumela ukuba ufumane ukuqonda okunzulu ngepateni yokuhamba kwegazi. |
| I-Duplex Ultrasound | Olu ludibaniso lwe-scan eqhelekileyo kunye ne-Doppler scan. Ingathatha umfanekiso we-blood vessel kwaye ibone indlela igazi elihamba ngayo ngaphakathi kuyo. Oku kuluncedo kakhulu ekujongeni ububanzi be-blood vessel kunye nokuba kukho na ukuvaleka. |
| I-Power Doppler | Ayibonisi indlela igazi elihamba ngayo, kodwa inokunceda ekuboneni nokuba igazi lihamba kancinci kangakanani. Isetyenziselwa ukujonga imithambo yegazi emihle kakhulu engaphakathi kwamalungu omzimba. |
| I-Transcranial Doppler | Olu luvavanyo olwenziwe entloko ngokukodwa. Lunceda ekufumaneni izifo ezifana nestroke ngokujonga ukuhamba kwegazi ngaphakathi kwengqondo. |
Ngubani ofuna olu vavanyo lweDoppler?
Kukho izizathu ezahlukeneyo zokuba ugqirha wakho angayalela olu vavanyo. Ezona ziphambili zezi:
- Chonga izifo zemithambo yegazi: Ukuba ukrokrela ukuba kukho ingxaki ngemithambo yegazi esiswini sakho, emilenzeni, okanye ezingalweni (umz., umthambo uvalekile okanye uvuvukile), fumana ukuba yintoni kanye kanye.
- Jonga imeko emva kotyando: Emva kotyando, qiniseka ukuba igazi liya kwindawo efanelekileyo.
- Ngexesha lokukhulelwa: Oku kubaluleke kakhulu. Olu vavanyo lusetyenziselwa ukujonga ukuba ukuhamba kwegazi ukusuka kumama okhulelweyo ukuya kumntwana osesiswini kuhamba kakuhle na kwi-umbilical cord. Oku kunokunceda ekuqinisekiseni ukuba umntwana ufumana ioksijini kunye nezondlo azidingayo.
Zeziphi iimeko zempilo ezinokufunyaniswa ngesi skeni?
I-Doppler scan luvavanyo olubaluleke kakhulu olunika oogqirha ulwazi malunga nezifo ezininzi.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| Ukuncitshiswa kwemithambo yegazi | Ungabona ukuba izinto ezifana ne-cholesterol ziqokelelene kwaye zinciphise imithambo yegazi. |
| Amahlwili egazi | Iimeko eziyingozi ngakumbi ezifana nokuqhekeka kwegazi kwimithambo enzulu yemilenze (i-Deep Vein Thrombosis - DVT) zinokubonwa ngokukhawuleza. |
| Ukonakala kwemithambo yegazi | Jonga ukuba umthambo wegazi wonakele na ngenxa yengozi okanye esinye isizathu. |
| Ukungasebenzi kakuhle kwemithambo yegazi (i-CVI) | Jonga ukuba iivalvu ezisemithanjeni emilenzeni zibuthathaka na kwaye igazi liyahlangana emilenzeni endaweni yokubuyela entliziyweni. |
| Izizathu zoxinzelelo lwegazi oluphezulu | Ngamanye amaxesha uxinzelelo lwegazi oluphezulu lunokubangelwa ziingxaki zemithambo yegazi ehambisa igazi kwizintso. Khangela izizathu ezinjalo. |
| Emva kokufakelwa amalungu omzimba | Emva kokufakelwa ilungu elithile elifana nezintso okanye isibindi, qiniseka ukuba lifumana igazi elifanelekileyo. |
Ndingazilungiselela njani ngaphambi kolu vavanyo?
Oku kulula kakhulu. Kuya kufuneka ulandele amanyathelo ambalwa alula ngokuxhomekeke kuhlobo lweskeni oyenzayo.
- Ukuzila Ukutya: Usenokucelwa ukuba uyeke ukutya okanye ukusela kangangeeyure ezimbalwa ngaphambi kovavanyo, ingakumbi ukuba usenza iskeni yesisu. Oku kungenxa yokuba inkqubo yokugaya ukutya inokubangela utshintsho ekuhambeni kwegazi, nto leyo enokuchaphazela iziphumo zeskeni.
- Kuphephe ukutshaya: Kuphephe ukutshaya nokusebenzisa ezinye iimveliso ezine-nicotine ubuncinane iiyure ezimbini ngaphambi kokuba kuskeniwe. I-nicotine iyanciphisa (inciphisa) imithambo yegazi yakho, nto leyo enokuchaphazela iziphumo zeskeni.
Ugqirha wakho okanye indawo apho kwenziwa khona iskeni uza kukunika imiyalelo ecacileyo malunga noku.
Kwenzeka ntoni ngexesha leskeni?
Le nkqubo ilula kakhulu, kwaye awuyi kuva ntlungu. Idla ngokuthatha imizuzu engama-30 ukuya kwengama-60.
1. Ukulungiselela: Uza kuthathwa uye kwigumbi lovavanyo uze ucelwe ukuba ulale ebhedini. Ngokuxhomekeke kwindawo eskeniweyo, ungacelwa ukuba ujike ecaleni okanye uhlale phantsi.
2. Ukufaka ijeli: Ingcali ye-sonographer iza kufaka ijeli encinci efana namanzi eluswini lwakho, kwindawo eskeniweyo. Oku kuya kuvakala kubanda kancinci, kodwa akuyi kuba buhlungu. Le jeli inceda amaza esandi ukuba angene emzimbeni wakho ngokufanelekileyo.
3. Ukuskena: Emva koko, bahambisa isixhobo esincinci (iprobe/i-transducer) besiya phambili nangasemva phezu kwesikhumba esigqunywe ngejeli. Esi sixhobo sithumela amaza esandi angevayo aphezulu emzimbeni.
4. Ukuva isandi: La maza esandi angena ngaphakathi, abethe igazi elihambayo, aze abuyele umva. Njengoko igazi lihamba, uhlobo lwamaza esandi abuyayo luyatshintsha. Olu tshintsho yingakho unokuva isandi esithi "whoosh... whoosh..." esivela kwiskena. Eso sisandi segazi lakho elihambayo. Ungakhathazeki, kuyinto eqhelekileyo.
5. Ukudala imifanekiso: Umatshini ubona utshintsho kwezi zandi aze aziguqule zibe yimifanekiso okanye iigrafu kwisikrini sekhompyutha.
6. Isiphelo: Xa uvavanyo luphelile, ijeli efakwe emzimbeni wakho iya kusulwa uze ugoduke njengesiqhelo.
Ngaba kukho umngcipheko kule nto?
Akunjalo konke konke. I-Doppler ultrasound luvavanyo olukhuselekileyo kakhulu.
- Oku akubandakanyi imitha efana ne-X-ray okanye i-CT scan.
- Ngokungafaniyo novavanyo olufana ne-angiogram, akukho nto ifakwa emzimbeni.
- Oku akubuhlungu.
- Olu luvavanyo olukhuselekileyo kangangokuba noomama abakhulelweyo banokwenza ngaphandle koloyiko .
Ziza kufumaneka nini iziphumo?
Iziphumo zeskeni azifumaneki kwangoko. Ezi skeni kufuneka zihlolwe ngononophelo yingcali ye-radiology kwaye kulungiswe ingxelo. Oku kungathatha iintsuku ezimbalwa okanye iveki. Nje ukuba ufumane ingxelo, ugqirha wakho uza kuyijonga aze akuchazele imeko. Ngamanye amaxesha, kunokufuneka uvavanyo olongezelelweyo ngokusekelwe kwiziphumo. Thetha nogqirha wakho ngale nto.
Umyalezo Wokuya Ekhaya
- I-Doppler ultrasound yindlela elula kakhulu nekhuselekileyo yokuskena esebenzisa amaza esandi ukujonga indlela igazi elihamba ngayo ngaphakathi kwemithambo yegazi yakho .
- Oku kunokuchonga izinto ezininzi ezibalulekileyo, ezinje ngamahlwili egazi, ukuncitshiswa kwemithambo yegazi, kunye nendlela umntwana afumana ngayo igazi ngexesha lokukhulelwa.
- Olu vavanyo alunantlungu kwaphela kwaye alubandakanyi imitha efana ne-X-ray.
- Ukulandela imiyalelo elula, njengokuphepha ukutshaya ngaphambi kokuba kuskeniwe, kubaluleke kakhulu ukuze ufumane iziphumo ezichanekileyo.
- Ukuba unemibuzo malunga nolu vavanyo, ungathandabuzi ukubuza ugqirha wakho.
