Uma udokotela ekucela ukuthi wenze i-scan, ngezinye izikhathi uzizwa wesaba futhi unelukuluku, akunjalo? Ikakhulukazi uma bekucela ukuthi wenze i-"Doppler Ultrasound", igama liyaxaka kancane futhi ungase uzibuze ukuthi kuyini lokhu. Kodwa asikho isizathu sokwesaba. Lokhu ukuhlolwa okulula kakhulu, okungenabuhlungu, futhi okuphephile kakhulu. Ake sixoxe ngakho konke ngendlela elula kakhulu namuhla.
Kalula nje, iyini le Doppler ultrasound?
Cabanga ngemithambo yegazi emzimbeni wakho njengemigwaqo. Igazi lifana nezimoto ezihamba kule migwaqo. Ngakho-ke, bekungaba kuhle kangakanani ukube bekukhona indlela yokubona ukuthi lezi zimoto zihamba kahle yini, ukuthi zibhajwe esiminyaminyeni sezimoto, ukuthi zihamba ngesivinini esikhulu, noma ukuthi zihamba kancane kakhulu? Yilokho okwenziwa yi-Doppler ultrasound scan.
Lokhu kusebenzisa amaza omsindo ukudala izithombe zegazi elihamba emithanjeni yakho yegazi. Lezi zithombe zingabonisa ngokucacile isivinini kanye nesiqondiso sokugeleza kwegazi emithanjeni yakho yegazi (imithambo yegazi kanye nemithambo yegazi), kanye nendlela igazi eligeleza ngayo enhliziyweni yakho.
Ukuhlolwa okuvamile kwe-ultrasound kuthatha isithombe sesitho (isib. izinso, isibindi). Kodwa-ke, ukuhlolwa kwe-Doppler kungabheka imininingwane yegazi elihamba ngaphakathi kwaleso sitho noma ngaphakathi kwemithambo yegazi. Yilowo umehluko omkhulu phakathi kwalokhu okubili.
Zingaki izinhlobo ze-Doppler ultrasound ezikhona?
Yebo, kunezinhlobo eziningana ze-Doppler scan ezisetshenziswa odokotela kuye ngesidingo. Akudingeki ucabange kakhulu ngalezi, kodwa kuhle ukwazi okuncane.
| Uhlobo lokuskena | Kwenzekani ngalokhu? |
|---|---|
| I-Doppler Yombala | Kulokhu, ikhompyutha isebenzisa imibala ehlukene ukukhombisa indlela yokugeleza kwegazi. Isibonelo, igazi eligeleza ohlangothini olulodwa lingabonakala libomvu, kanti igazi eligeleza kolunye uhlangothi libonakala liluhlaza okwesibhakabhaka. |
| I-Spectral Doppler | Iphethini yokugeleza kwegazi iboniswa njengegrafu. Lokhu kukuvumela ukuthi uthole ukuqonda okujulile ngephethini yokugeleza kwegazi. |
| I-Duplex Ultrasound | Lokhu kuyinhlanganisela yokuskena okuvamile kanye nokuskena kwe-Doppler. Kungathatha isithombe somthambo wegazi bese kubheka ukuthi igazi ligeleza kanjani ngaphakathi kwawo. Lokhu kuwusizo kakhulu ekuhloleni ububanzi bomthambo wegazi nokuthi ngabe kukhona yini ukuvaleka. |
| I-Power Doppler | Ayibonisi ukuthi igazi lihamba kanjani, kodwa ingasiza ekuboneni ngisho nokugeleza kwegazi okuhamba kancane kakhulu. Isetshenziselwa ukubheka imithambo yegazi emihle kakhulu ngaphakathi kwezitho zomzimba. |
| I-Transcranial Doppler | Lokhu ukuskena okwenziwa ngqo ekhanda. Kusiza ekutholeni izimo ezifana nesifo sohlangothi ngokubheka ukugeleza kwegazi ngaphakathi kobuchopho. |
Ubani odinga lesi sikeni se-Doppler?
Kunezizathu eziningana zokuthi kungani udokotela wakho engase acele lolu vivinyo. Eziyinhloko yilezi:
- Thola izifo zemithambo yegazi: Uma usola ukuthi kunenkinga ngemithambo yegazi esiswini sakho, emilenzeni, noma ezingalweni (isb., umthambo uvalekile noma uvuvukele), thola ukuthi uyini ngempela.
- Hlola isimo ngemva kokuhlinzwa: Ngemva kwanoma yikuphi ukuhlinzwa, qiniseka ukuthi ukugeleza kwegazi endaweni kwanele.
- Ngesikhathi sokukhulelwa: Lokhu kubaluleke kakhulu. Lokhu kuskena kusetshenziselwa ukuhlola ukuthi ukugeleza kwegazi kusuka kumama okhulelwe kuya enganeni esibelethweni kuhamba kahle yini ngentambo yesisu. Lokhu kungasiza ekunqumeni ukuthi ingane ithola umoya-mpilo kanye nezakhamzimba ezidingayo.
Yiziphi izimo zezokwelapha ezingatholakala ngalesi sikeni?
I-Doppler scan iyisivivinyo esibaluleke kakhulu esinikeza odokotela ulwazi mayelana nezifo eziningi.
| Isimo sezokwelapha | Incazelo elula |
|---|---|
| Ukuncishiswa kwemithambo yegazi | Ungabona ukuthi izinto ezifana ne-cholesterol zinqwabelene futhi zanciphisa imithambo yegazi. |
| Amahlule egazi | Izimo eziyingozi kakhulu njengezinhlayiya zegazi emithanjeni ejulile yemilenze (i-Deep Vein Thrombosis - DVT) zingabonakala ngokushesha. |
| Ukulimala kwemithambo yegazi | Hlola ukuthi umthambo wegazi wonakele yini ngenxa yengozi noma esinye isizathu. |
| Ukungasebenzi kahle kwemithambo yegazi okungapheli (CVI) | Hlola ukuthi ama-valve emithanjeni emilenzeni abuthakathaka yini nokuthi igazi liyahlangana yini emilenzeni esikhundleni sokubuyela enhliziyweni. |
| Izimbangela zomfutho wegazi ophakeme | Ngezinye izikhathi umfutho wegazi ophezulu ungabangelwa izinkinga ngemithambo yegazi ehambisa igazi ezinso. Funa izimbangela ezinjalo. |
| Ngemva kokufakelwa isitho | Ngemva kokufakelwa isitho esinjengezinso noma isibindi, qiniseka ukuthi sithola igazi elifanele. |
Kufanele ngilungiselele kanjani ngaphambi kwalolu vivinyo?
Lokhu kulula kakhulu. Kuzodingeka ulandele izinyathelo ezimbalwa ezilula kuye ngohlobo lokuskena okwenzayo.
- Ukuzila Ukudla: Ungase ucelwe ukuthi uyeke ukudla noma ukuphuza amahora ambalwa ngaphambi kokuhlolwa, ikakhulukazi uma uhlolwa isisu. Lokhu kungenxa yokuthi inqubo yokugaya ukudla ingabangela izinguquko ekugelezeni kwegazi, okungathinta imiphumela yokuhlolwa.
- Gwema ukubhema: Gwema ukubhema nokusebenzisa eminye imikhiqizo equkethe i-nicotine okungenani amahora amabili ngaphambi kokuskena. I-nicotine inciphisa (inciphisa) imithambo yegazi yakho, okungathinta imiphumela yokuskena.
Udokotela wakho noma indawo lapho kwenziwa khona ukuskena kuzokunikeza imiyalelo ecacile ngalokhu.
Kwenzekani ngesikhathi sokuskena?
Le nqubo ilula kakhulu, futhi ngeke uzwe ubuhlungu. Ngokuvamile kuthatha imizuzu engama-30 kuya kwengama-60.
1. Ukulungiselela: Uzoyiswa ekamelweni lokuhlolwa bese ucelwa ukuba ulale embhedeni. Kuye ngendawo eskeniwe, ungase ucelwe ukuthi uphendukele eceleni noma uhlale phansi.
2. Ukufaka ijeli: Udokotela we-sonographer uzofaka inani elincane lejeli efana namanzi esikhumbeni sakho, endaweni eskeniwe. Lokhu kuzozwakala kubanda kancane, kodwa ngeke kube yinto engakhululekile. Le jeli isiza amaza omsindo ukuthi angene kahle emzimbeni wakho.
3. Ukuskena: Bese, bahambisa idivayisi encane (i-probe/i-transducer) emuva naphambili phezu kwesikhumba esimbozwe ngejeli. Le divayisi ithumela amaza omsindo angezwakali kahle emzimbeni.
4. Ukuzwa umsindo: Lawa maza omsindo angena ngaphakathi, ashaye igazi elihambayo, bese ebuyela emuva. Njengoba igazi lihamba, uhlobo lwamaza omsindo abuyayo luyashintsha. Lolu shintsho yingakho ungase uzwe umsindo othi "whoosh... whoosh..." ovela kusikena. Lowo umsindo wegazi lakho ligeleza. Ungakhathazeki, kuvamile.
5. Ukudala izithombe: Umshini uthola izinguquko kula maza omsindo bese uwaguqula abe izithombe noma amagrafu esikrinini sekhompyutha.
6. Isiphetho: Uma isivivinyo sesiphelile, ijeli elifakwe emzimbeni wakho lizosulwa bese ubuyela ekhaya njengenjwayelo.
Ingabe kukhona ingozi kulokhu?
Lutho neze. I-Doppler ultrasound iyindlela yokuhlola ephephile kakhulu.
- Lokhu akubandakanyi imisebe efana ne-X-ray noma i-CT scan.
- Ngokungafani nokuhlolwa okufana ne-angiogram, akukho lutho olufakwa emzimbeni.
- Lokhu akubuhlungu.
- Lolu uhlobo lokuhlolwa oluphephile kangangokuthi ngisho nomama abakhulelwe bangakwenza ngaphandle kokwesaba .
Imiphumela izotholakala nini?
Imiphumela yokuskena ayitholakali ngokushesha. Lezi ziskena zidinga ukubuyekezwa ngokucophelela ngudokotela we-radiologist bese kulungiswa umbiko. Lokhu kungathatha izinsuku ezimbalwa noma isonto. Uma usuwutholile umbiko, udokotela wakho uzowubuyekeza futhi akuchazele isimo. Ngezinye izikhathi, kungase kudingeke ukuhlolwa okwengeziwe ngokusekelwe emiphumeleni. Khuluma nodokotela wakho ngalokhu.
Umlayezo Wokuya Nawe Ekhaya
- I-Doppler ultrasound iyindlela elula kakhulu futhi ephephile yokuskena esebenzisa amaza omsindo ukubheka indlela igazi eligeleza ngayo ngaphakathi kwemithambo yegazi yakho .
- Lokhu kungabona izinto eziningi ezibalulekile, njengokuqhekeka kwegazi, ukuncipha kwemithambo yegazi, kanye nendlela umntwana athola ngayo igazi ngesikhathi sokukhulelwa.
- Lokhu kuhlolwa akubuhlungu nhlobo futhi akubandakanyi imisebe njenge-X-ray.
- Ukulandela imiyalelo elula, njengokugwema ukubhema ngaphambi kokuskena, kubaluleke kakhulu ukuthola imiphumela enembile.
- Uma unemibuzo mayelana nalolu vivinyo, ungangabazi ukubuza udokotela wakho.
