I-Doppler ultrasound iwuhlobo lwe-ultrasound, enezindlela ezithile, ezivumela ukubonwa ngombala kokugeleza kwegazi emithanjeni nasemithanjeni yomzimba, kusiza ukuqinisekisa ukusebenza kwezicubu, njengezindonga zenhliziyo, izinzwa nobuchopho .

Luhlobo lokuhlolwa okungangenisi, okungukuthi, alusebenzisi izinaliti futhi aludingi ukuthi kwenziwe i-anesthesia, futhi lwenziwa ngudokotela we-radiologist, ozodlulisa i-gel transducer, okuyingxenye encane ye-ultrasound device, endaweni yomzimba ezohlolwa.

Ngokusebenzisa i-Doppler echocardiography, kungenzeka ukuthi kuhlolwe izifo ezahlukahlukene ezifana ne-atherosclerosis, vasculitis kanye ne-aneurysms, yingakho kuvame ukukhonjiswa ngudokotela wenhliziyo noma we-neurologist. Kodwa-ke, lokhu kuhlolwa kukhonjiswa nangongoti bezokubelethisa ukuze babheke izimo zempilo yengane ngesikhathi sokukhulelwa.

Yenzelwe ini

I-Doppler ultrasound uhlobo lwe-ultrasound esetshenziselwa ukuhlola ukugeleza kwegazi emithanjeni nasemithanjeni yegazi, inhliziyo, ubuchopho ngisho nezitho ezingezansi. Ngakho-ke, lokhu kuhlolwa kungakhonjiswa ngezimo ezilandelayo:

• Thola ukuvinjelwa ngamafutha emithanjeni noma emithanjeni;
• Thola amahlule egazini emithanjeni yengalo noma emlenzeni;
• Bheka ukuthi kukhona yini ukujiya kodonga lwemithambo noma lwemithambo;
• Hlaziya imiphumela yokuhlinzwa okwenziwe enhliziyweni;
• Linganisa izici zemithambo ye-varicose.

Ngaphezu kwalokho, ukuskena kweDoppler kungasiza futhi ukuhlola umfutho wegazi ngaphakathi emithanjeni, kukhombisa inani legazi eligeleza emithanjeni yegazi futhi kungenziwa njengokunye okunye ukuhlolwa okuhlaselayo, njenge-angiography, okubandakanya ukujova umehluko emthanjeni.

Lokhu kuhlolwa kungenziwa nasezinganeni futhi kuvame ukunconywa udokotela wezingane ukuhlola ukuthi ngabe kukhona yini ukungalungi enhliziyweni noma ukusiza ekubekweni kwepayipi eliphakathi nendawo le-venous. Bona okuningi ukuthi iyiphi i-catheter ye-venous emaphakathi futhi kukhonjiswa kuziphi izimo.

Kwenziwa kanjani

Ukuhlolwa kwe-ecodoppler kwenziwa ngudokotela oyi-radiologist egumbini eliseyunithi, noma isikhungo sokuxilonga, futhi akudingi i-anesthesia noma ukungafani emthanjeni, ngaphezu kokuthi ayikho imisebe esetshenziswayo.

Ukuze wenze isivivinyo kuyadingeka ukuthi umuntu agqoke iphinifa alale ku-stretcher. Ngemuva kwalokho udokotela uzofaka ijeli bese ehambisa i-transducer esikhunjeni, okuyithuluzi elincane okuzokwazi ukubuka ngalo izingxenye zangaphakathi zomzimba, njengemithambo nemithambo yegazi. Lokhu akubangeli ubuhlungu noma ukungaphatheki kahle.

Udokotela uzobuka izithombe esikrinini sekhompyutha bese ehlaziya ukwakheka komzimba, bese kuthi ngemuva kwezinsuku ezimbalwa, kukhishwe umbiko onencazelo yalokho okutholwe ekuhlolweni bese lo mbiko walethwa kudokotela ocelile it.

Ukulungiselela ukuhlolwa

Ezimweni eziningi, akukho ukunakekelwa okuthile okudingekayo ukwenza ukuhlolwa, kodwa-ke, abantu abasebenzisa imishanguzo eguqula umfutho wegazi noma ababhemayo, kufanele bazise udokotela ozohlola, ngoba lezi zimo zingakhuphula ukuhamba kwegazi emithanjeni nemithambo yomzimba.

Yiziphi izinhlobo zeDoppler Doppler

Ngokuya ngengxenye noma isakhiwo somzimba udokotela afuna ukusihlaziya, ukuhlolwa kungaba:

• I-echocardiography yesisu: eyenziwa ngesikhathi sokukhulelwa, iqukethe ukuhlolwa kwenhliziyo yengane;
• I-Doppler echocardiography yemilenze ephansi: isebenza ukuhlaziya imithambo nemithambo yemilenze;
• I-Doppler echocardiography yamalungu aphezulu: kuqukethe ukuhlola isimo semithambo nemithambo yezingalo;
• I-carodid echodoppler: kukhonjisiwe ukuhlola umthambo onikezela ngegazi esifundeni sekhanda;
• I-ecodoppler yemithambo yezinso: welulekwa ngokuhlaziywa kwemithambo yezinso nemithambo;
• I-Doppler yaseTranscranial: Kunconywa ukuhlola imithambo nemithambo yegazi yobuchopho;
• Indlala yegilo: uhlobo olusebenza ukubheka ukuhamba kwegazi ku-thyroid.

Lezi zinhlobo ezithile ze-Doppler echocardiography zingacelwa lapho uthintana nodokotela wenhliziyo noma we-neurologist, kepha futhi zingakhonjiswa kubantu abangeniswa esibhedlela benokusola kwesifo esithile noma ukuphazamiseka okuthile.

Izifo eziyinhloko ezitholakele

I-Doppler ultrasound, noma i-ultrasound doppler, ingakhonjiswa ngudokotela wenhliziyo, i-neurologist noma i-nephrologist ukuphenya nokuhlola ezinye izifo ezinjenge:

1. Isifo sokuqina kwemithambo yegazi

I-atherosclerosis yisifo esenzeka ngenxa yokuqongelela kwamapuleti anamafutha, noma ama-atheromas, engxenyeni yemithambo yenhliziyo nokuthi uma ishiywe ingalashwa ingavimba ukuhamba kwegazi futhi iholele ekubonakaleni kwezinkinga ezinkulu ezifana ne-acute myocardial infarction kanye nengozi yemithambo yegazi yobuchopho.

I-Echocardiography wuhlobo lokuhlola olusetshenziswa kabanzi ukuphenya ngalesi sifo, kepha-ke, udokotela wenhliziyo angahle ahlele ezinye izivivinyo ezifana ne-angiography kanye ne-catheterization yenhliziyo. Ngemuva kokuthola lolu shintsho, udokotela uzoncoma ukwelashwa okufanelekile kakhulu ngokuya ngoshintsho emikhubeni nasemithini. Bona ezinye izinketho zokwelashwa kwe-atherosclerosis.

2. I-Vasculitis

I-Vasculitis inguquko ebangelwa ukuvuvukala kwemithambo yegazi emzimbeni futhi ingadala izimpawu ezinjengamachashazi abomvu esikhunjeni, ukuncinza noma ukulahlekelwa umuzwa ezandleni noma ezinyaweni, ubuhlungu bamalunga nomkhuhlane. Lesi sifo singadalwa ezinye izimo ezifana nokutheleleka, izifo ezizimele nomdlavuza futhi, kwezinye izimo, kungaholela ezinkingeni ezifana nokopha.

Isazi se-rheumatologist kufanele sithintwe uma kwenzeka sisolwa nge-vasculitis, futhi singakhombisa i-echocardiogram ukuqinisekisa ukuxilongwa. Ukwelashwa kwalesi sifo kunconywa udokotela ngokusho kobukhulu nendawo yokuvuvukala kwemithambo yegazi. Bheka ezinye izivivinyo ezingenziwa ukuqinisekisa ukutholakala kwe-vasculitis nokuthi iyiphi indlela yokwelashwa.

3. Ama-Aneurysms

Ama-Aneurysms angavela ngenxa yokwanda kwengcindezi igazi elidlula ngayo emthanjeni wegazi, okuholela ekwakhekeni kokuqina komthambo noma udonga lomthambo. Lokhu kunwebeka kungenzeka emithanjeni yegazi yenhliziyo, ebuchosheni noma ezingxenyeni zomzimba, njenge-aorta yesisu, ngokwesibonelo.

Izimpawu zincike lapho kutholakala khona i-aneurysm, futhi abantu abahlangabezana nalolu shintsho bangaba nobuhlungu obukhulu endaweni, ubunzima bokuhamba, ukuhayiza ekhanda, ukungaboni kahle ngisho nokuquleka futhi kufanele bafune usizo oluphuthumayo esibhedlela. Bheka ezinye izimpawu eziyinhloko ze-aneurysm ye-cerebral ne-aortic.

4. I-thrombosis ejulile ye-venous

I-vein thrombosis ejulile yisimo esenzeka ngenxa yokuvinjelwa komthambo ojulile emlenzeni, ethangeni noma esiswini, okwehlisa ukugeleza kwegazi futhi, ezimweni eziningi, kubangela ukuvuvukala, ubuhlungu obukhulu kanye nombala onsomi emlenzeni, isibonelo.

Ezinye izinto ezinobungozi zihlobene nokubonakala kwe-thrombosis enesibindi efana nomdlavuza, ukuhlinzwa okukhulu, ukusetshenziswa kwezindlela zokuvimbela inzalo ngomlomo nokunyakaza okuncane komzimba, kanti ukuxilongwa kwenziwa nge-echocardiography. Imvamisa, ukulaliswa esibhedlela kuyadingeka ekwelapheni lesi sifo, esincike ekusetshenzisweni kwemithi elwa negciwane, njenge-heparin. Funda ukuthi ungayivimbela kanjani i-thrombosis emlenzeni.

5. I-renal artery stenosis

I-renal artery stenosis ichazwa njengokuncipha komthambo omkhulu wezinso ngenxa yamapuleti anamafutha, ihlule legazi noma isimila, futhi ukuxilongwa kwalolu shintsho kwenziwa ngokuhlolwa okufana ne-angiography ne-renal Doppler.

Ukwelashwa kwe-renal artery stenosis kuboniswa yi-nephrologist futhi kuqukethe i-catheterization, ukuhlinzwa kanye nokusetshenziswa kwezidakamizwa ze-anticoagulant kanye ne-thrombolytic. Imvamisa, lokhu kwelashwa kufanele kwenziwe nomuntu ongeniswe esibhedlela ukuthola imishanguzo ngomthambo futhi kufanele kuqalwe ngokushesha okukhulu ukugwema izinkinga ezifana ne-pulmonary edema.
