I-Doppler ultrasound luhlobo lwe-ultrasound, eneendlela ezithile, ezivumela ukubonwa ngombala kokuhamba kwegazi kwimithambo kunye nemithambo yomzimba, kunceda ekuqinisekiseni ukusebenza kwezicubu, ezinje ngeendonga zentliziyo, imithambo kunye nengqondo .

Luhlobo lovavanyo olungadibaniyo, oko kukuthi, alusebenzisi iinaliti kwaye aludingi kwenziwa kwi-anesthesia, kwaye lwenziwa yi-radiologist, oza kudlulisa i-gel transducer, eyinxalenye encinci ye-ultrasound isixhobo, kwindawo yomzimba eza kuvavanywa.

Ngokusebenzisa i-Doppler echocardiography, kunokwenzeka ukuba uchaze izifo ezahlukeneyo ezinje nge-atherosclerosis, vasculitis kunye ne-aneurysms, yiyo loo nto ihlala iboniswa ngugqirha wezifo zentliziyo okanye ugqirha wemithambo-luvo. Nangona kunjalo, olu vavanyo lukwaboniswa ngoochwephesha ukuze bajonge imeko yezempilo yomntwana ngexesha lokukhulelwa.

Yenzelwe ntoni

I-Doppler ultrasound luhlobo lwe-ultrasound esetyenziselwa ukukhangela ukuhamba kwegazi kwimithambo kunye nemithambo, intliziyo, ingqondo kunye namalungu asezantsi. Ke, olu vavanyo lunokuboniswa kwezi meko zilandelayo:

• Fumana izithintelo ngamafutha kwimithambo okanye kwimithambo;
• Beka amahlwili egazi kwimithambo yengalo okanye yomlenze;
• Jonga ukuba kukho naluphi na ukwanda kodonga lwemithambo okanye lwemithambo;
• Hlaziya iziphumo zotyando olwenziwe entliziyweni;
• Vavanya iimpawu zemithambo ye-varicose.

Ukongeza, i-Doppler scan inokukunceda ukujonga uxinzelelo lwegazi ngaphakathi kwimithambo, ibonisa inani legazi elihamba kwimithambo yegazi kwaye inokwenziwa njengenye indlela yovavanyo olungenelelayo, njenge-angiography, ebandakanya inaliti ye Umahluko kumthambo.

Olu vavanyo lunokwenziwa nakwabantwana kwaye ngokubanzi kucetyiswa ngugqirha wabantwana ukuvavanya ukuba ngaba kukho nayiphi na into engalunganga entliziyweni okanye ukunceda ekubekeni i-catheter ye-venous esembindini. Bona ngakumbi ukuba yeyiphi into ekuthiwa yi-catheter esembindini kwaye iboniswa kweyiphi imeko.

Kwenziwa njani

Uvavanyo lwe-ecodoppler lwenziwa yi-radiologist kwigumbi elikwiyunithi, okanye iziko lokuqonda isifo, kwaye alifuni kubulawa mayeza okanye kwahluka emthanjeni, ukongeza kwinto yokuba akukho radiation iyasetyenziswayo.

Ukwenza uvavanyo kunyanzelekile ukuba umntu abeke ifaskoti kwaye alale kwi-stretcher. Emva koko ugqirha uya kufaka ijeli kwaye ahambise i-transducer eluswini, sisixhobo esincinci esinokuthi sikwazi ukujonga amalungu angaphakathi omzimba, njengemithambo kunye nemithambo. Oku akubangeli zintlungu okanye ukuphazamiseka.

Ugqirha uzakuyijonga le mifanekiso kwiscreen sekhompyuter kwaye ahlalutye ubume bomzimba, kwaye emva kweentsuku ezimbalwa, kuya kukhutshwa ingxelo nenkcazo yoko kufunyenwe kuvavanyo kwaye le ngxelo mayisiwe kugqirha ocelileyo. yiyo.

Ukulungiselela uviwo

Kwiimeko ezininzi, akukho nkathalo ithile iyafuneka ukwenza uvavanyo, nangona kunjalo, abantu abasebenzisa iziyobisi eziguqula uxinzelelo lwegazi okanye abatshayayo, kufuneka bazise ugqirha oza kuthi enze uvavanyo, kuba ezi meko zinokunyusa ukuhamba kwegazi emithanjeni. kunye nemithambo yomzimba.

Zeziphi iintlobo zeDoppler Doppler

Kuxhomekeke kwinxalenye okanye kubume bomzimba ugqirha afuna ukuwuhlalutya, uvavanyo lunokuba:

• I-echocardiography yomntwana: lwenziwa ngexesha lokukhulelwa, luquka uvavanyo lwentliziyo yomntwana;
• I-Doppler echocardiography yamalungu asezantsi: isebenza ukuhlalutya imithambo kunye nemithambo yemilenze;
• I-Doppler echocardiography yamalungu aphezulu: iquka ukujonga imeko yemithambo kunye nemithambo yeengalo;
• I-carodid echodoppler: kubonisiwe ukujonga umthambo obonelela ngegazi kwingingqi yentloko;
• I-ecodoppler yemithambo yegazi: icetyiswa ukuhlalutya imithambo yezintso kunye nemithambo;
• Doppler yokudlulisa: kucetyiswa ukuvavanya imithambo kunye nemithambo yengqondo;
• Idlala ekuthiwa yi-Doppler: luhlobo olusebenzela ukujonga ukuhamba kwegazi kwi-thyroid.

Ezi ntlobo zithile ze-Doppler echocardiography zinokucelwa xa unxibelelana nogqirha wentliziyo okanye ugqirha wemithambo-luvo, kodwa zinokuboniswa kubantu abangeniswe esibhedlele ngokukrokrela isifo esithile okanye ukuphazamiseka.

Izifo eziphambili ezichongiweyo

I-Doppler ultrasound, okanye i-ultrasound doppler, ingabonakaliswa ngugqirha we-cardiovascular doctor, i-neurologist okanye i-nephrologist ukuphanda nokufumanisa ezinye izifo ezifana ne:

1. Isifo sokuqina kwemithambo yegazi

I-atherosclerosis sisifo esenzeka ngenxa yokuqokelelwa kwamacwecwe amanqatha, okanye i-atheromas, kwinxalenye yemithambo yentliziyo kwaye ukuba iyekwe inganyangwa ayikwazi ukuthintela ukuhamba kwegazi kwaye ikhokelele ekubonakaleni kweengxaki ezinje nge-infyoction ye-myocardial kunye neengozi ze-cerebral vascular system.

I-Echocardiography luhlobo lovavanyo olusetyenziswa ngokubanzi ukuphanda esi sifo, nangona kunjalo, ugqirha wezentliziyo unokuyalela ezinye iimvavanyo ezinje nge-angiography kunye ne-catheterization yentliziyo. Emva kokufumanisa olu tshintsho, ugqirha uya kuncomela olona nyango lufanelekileyo olusekwe kutshintsho kwimikhwa nakumayeza. Bona ezinye iindlela zokonyango ze-atherosclerosis.

2. I-Vasculitis

I-Vasculitis lutshintsho olubangelwa kukudumba kwemithambo yegazi emzimbeni kwaye kunokubangela iimpawu ezinje ngombala obomvu kulusu, ukurhawuzelela okanye ukulahleka kovalo ezandleni nasezinyaweni, iintlungu ezidibeneyo kunye nomkhuhlane. Esi sifo sinokubangelwa zezinye iimeko ezifana nosulelo, izifo ezizimela kunye nomhlaza kwaye, kwezinye iimeko, zikhokelela kwiingxaki ezinjengokopha.

I-rheumatologist kufuneka idibane kwimeko ye-vasculitis, kwaye ingabonisa i-echocardiogram ukuqinisekisa ukuxilongwa. Unyango lwesi sifo luyacetyiswa ngugqirha ngokobungqongqo kunye nendawo yokudumba kwemithambo yegazi. Jonga ezinye iimvavanyo ezinokwenziwa ukuqinisekisa isifo se-vasculitis kwaye loluphi unyango.

3. Iimpawu zemihla ngemihla

Ii-Aneurysms zinokuvela ngenxa yokwanda koxinzelelo apho igazi lidlula kwisitya segazi, esikhokelela ekwakheni ukwanda kwemithambo okanye udonga lwemithambo. Oku kuncipha kunokwenzeka kwimithambo yegazi yentliziyo, ingqondo okanye amalungu omzimba, anje ngesisu esiswini, umzekelo.

Iimpawu zixhomekeke kwindawo ekuyo i-aneurysm, kwaye abantu abanengxaki kolu tshintsho banokuba nentlungu ebuhlungu kuloo ndawo, ubunzima ekuhambeni, ukugungqa entloko, ukungaboni kakuhle kunye nokuhlutha kwaye kufuneka bafune ukhathalelo olungxamisekileyo esibhedlele. Jonga ngakumbi ezona mpawu ziphambili ze-cerebral kunye ne-aortic aneurysm.

4. I-thrombosis enzulu yemithambo

I-vein thrombosis enzulu yimeko eyenzeka ngenxa yokuthintelwa kwemithambo enzulu emlenzeni, ethangeni okanye esiswini, ethintela ukuhamba kwegazi kwaye, kwiimeko ezininzi, ibangela ukudumba, iintlungu eziqatha kunye nombala omfusa emlenzeni, umzekelo.

Eminye yemingcipheko inxulumene nokubonakala kwe-venous thrombosis enje ngomhlaza, utyando olukhulu, ukusetyenziswa kwezicwangcisi zomlomo kunye nentshukumo encinci yomzimba, kwaye ukuxilongwa kwenziwa nge-echocardiography. Rhoqo, ukulaliswa esibhedlele kuyimfuneko kunyango lwesi sifo, esekwe ekusetyenzisweni kweziyobisi ze-anticoagulant, ezifana ne-heparin. Funda ngendlela yokuthintela i-thrombosis emlenzeni.

5. Ukuqina kwemithambo yegazi esiswini

I-renal artery stenosis ichazwa njengokuncipha komthambo ophambili wezintso ngenxa yamanqatha anamanqatha, igazi elijiyileyo okanye ithumba, kwaye ukuxilongwa kolu tshintsho kwenziwa ngeemvavanyo ezinjenge-angiography kunye ne-renal Doppler.

Unyango lwe-renal artery stenosis luboniswa yi-nephrologist kwaye luqukethe i-catheterization, utyando kunye nokusetyenziswa kwe-anticoagulant kunye ne-thrombolytic drug. Rhoqo, olu nyango kufuneka lwenziwe nomntu ongeniswe esibhedlele ukuze afumane amayeza ngomthambo kwaye kufuneka uqalwe ngokukhawuleza ukunqanda iingxaki ezinjenge-edema yemiphunga.
