Kodi Doppler, mitundu yayikulu ndi chiyani?

Zamkati

• Ndi chiyani
• Zatheka bwanji
• Kukonzekera mayeso
• Kodi mitundu ya Doppler Doppler ndi iti?
• Matenda akulu omwe amapezeka
• 1. Matenda a m'mimba
• 2. Vasculitis
• 3. Zozizwitsa
• 4. Kuzama kwa venous thrombosis
• 5. Aimpso mtsempha wamagazi stenosis

Doppler ultrasound ndi mtundu wa ultrasound, wokhala ndi njira zina, zomwe zimalola kuwonekera kwamitundu yamagazi m'mitsempha ndi m'mitsempha ya thupi, ndikuthandizira kutsimikizira kugwira ntchito kwa minyewa, monga makoma a mtima, misempha ndi ubongo .

Ndi mtundu wa mayeso osasokoneza, ndiye kuti, sagwiritsa ntchito singano ndipo safuna kuti opaleshoni ichitike, ndipo imachitidwa ndi radiologist, yemwe adzapereke gel transducer, yomwe ndi gawo laling'ono la ultrasound chipangizo, pamalo obisika kuti ayesedwe.

Kudzera mu Doppler echocardiography, ndizotheka kuzindikira matenda osiyanasiyana monga atherosclerosis, vasculitis ndi aneurysms, ndichifukwa chake nthawi zambiri amawonetsedwa ndi katswiri wamatenda kapena wamaubongo. Komabe, kuwunikaku kumawonetsedwanso ndi madokotala azachipatala kuti awone ngati ali ndi pakati.

Ndi chiyani

Doppler ultrasound ndi mtundu wa ultrasound womwe umagwiritsidwa ntchito poyang'ana magazi m'mitsempha ndi m'mitsempha, mtima, ubongo komanso ngakhale miyendo yakumunsi. Chifukwa chake, mayeso awa atha kuwonetsedwa pazochitika izi:

• Pezani zoletsa ndi mafuta m'mitsempha kapena m'mitsempha;
• Ikani magazi m'mitsempha yam'mimba kapena mwendo;
• Onetsetsani ngati pali kuchepa kwa khoma la mitsempha kapena mitsempha;
• Fufuzani zotsatira za maopareshoni ochitidwa pamtima;
• Ganizirani za minyewa ya varicose.

Kuphatikiza apo, kuyesa kwa Doppler kungathandizenso kuwunika kuthamanga kwa magazi mkati mwa mitsempha, kuwonetsa kuchuluka kwa magazi omwe amayenda m'mitsempha yamagazi ndipo kutha kuchitidwa ngati njira ina yoyeserera ina, monga angiography, yomwe imakhudza jekeseni wa kusiyanasiyana kwamitsempha.

Mayesowa amathanso kuchitidwa kwa ana ndipo amalimbikitsidwa ndi dokotala wa ana kuti awone ngati pali zolakwika zilizonse mumtima kapena kuthandizira kukhazikitsidwa kwa catheter yapakati ya venous. Onani zambiri zomwe zili catheter yapakati komanso yomwe imawonetsedwa.

Zatheka bwanji

Kuyeza kwa ecodoppler kumachitika ndi radiologist m'chipinda mu chipinda, kapena malo ophunzirira, ndipo sikutanthauza ochititsa dzanzi kapena kusiyanitsa pamitsempha, kuphatikiza poti palibe radiation yomwe imagwiritsidwa ntchito.

Kuti muchite mayeso ndikofunikira kuti munthuyo avale epuroni ndikugona pakama. Kenako adotolo azipaka gel osunthira transducer kudzera pakhungu, chomwe ndi chida chaching'ono chomwe chitha kuwona ziwalo zamkati mwa thupi, monga mitsempha ndi mitsempha. Izi sizimayambitsa kupweteka kapena kusapeza bwino.

Dokotala adzawona zithunzizo pakompyuta ndikusanthula momwe thupi lilili, ndipo patatha masiku ochepa, lipoti liperekedwe ndikufotokozera zomwe zapezeka pakuwunika ndipo lipotili liyenera kuperekedwa kwa dokotala yemwe wapempha izo.

Kukonzekera mayeso

Nthawi zambiri, sipafunika chisamaliro chapadera kuti athe kuyesa, komabe, anthu omwe amagwiritsa ntchito mankhwala osokoneza bongo omwe amasintha kuthamanga kwa magazi kapena omwe amasuta, ayenera kudziwitsa adotolo omwe akayezetse, chifukwa izi zitha kukulitsa magazi m'mitsempha ndi mitsempha ya thupi.

Kodi mitundu ya Doppler Doppler ndi iti?

Kutengera gawo kapena kapangidwe ka thupi lomwe dokotala akufuna kuti lifufuzidwe, mayeso akhoza kukhala:

• Zojambulajambula za fetal: anachita pa mimba, imakhala ndi kuwunika mtima kwa mwana;
• Doppler echocardiography yamiyendo yakumunsi: imagwira ntchito yosanthula mitsempha ndi mitsempha ya miyendo;
• Doppler echocardiography yamiyendo yakumtunda: zimaphatikizapo kuyang'ana momwe mitsempha ndi mitsempha ya manja zilili;
• Carotid echodoppler: adawonetsa kuti ayang'ane mtsempha womwe umapereka magazi kumtunda;
• Ecodoppler ya mitsempha yaimpso: analangiza kusanthula mitsempha ya impso ndi mitsempha;
• Doppler Wopanga: analimbikitsa kuyesa mitsempha ndi mitsempha ya ubongo;
• Chithokomiro Chopopera: ndi mtundu womwe umathandizira kuwunika momwe magazi amayendera mu chithokomiro.

Mitundu iyi ya Doppler echocardiography itha kufunsidwa mukamafunsira kwa dokotala wamtima kapena wamankhwala am'mimba, koma amathanso kuwonetsedwa kwa anthu omwe alandilidwa kuchipatala ndikukayikira matenda ena kapena matenda.

Matenda akulu omwe amapezeka

Doppler ultrasound, kapena ultrasound doppler, imatha kuwonetsedwa ndi dokotala wamtima, neurologist kapena nephrologist kuti mufufuze ndikupeza matenda ena monga:

1. Matenda a m'mimba

Matenda a atherosclerosis ndi matenda omwe amabwera chifukwa chodzaza mafuta, kapena ma atheromas, m'magawo amitsempha yamtima ndipo ngati atapanda kuchiritsidwa amatha kuletsa kuyenda kwa magazi ndikupangitsa kuti pakhale zovuta zina monga pachimake m'mnyewa wamtima ndi ngozi ubongo dongosolo mtima.

Echocardiography ndi mtundu wa mayeso omwe amagwiritsidwa ntchito kwambiri kuti afufuze za matendawa, komabe, katswiri wa zamagetsi amatha kuyitanitsa mayeso ena monga angiography ndi catheterization yamtima. Atazindikira kusinthaku, adotolo amalangiza chithandizo choyenera kwambiri kutengera kusintha kwa zizolowezi ndi mankhwala. Onani njira zina zochiritsira atherosclerosis.

2. Vasculitis

Vasculitis ndimasinthidwe omwe amayamba chifukwa cha kutupa kwa mitsempha yamagazi mthupi ndipo imatha kuyambitsa zizindikilo monga zigamba zofiira pakhungu, kumva kulasalasa kapena kutaya mphamvu m'manja kapena m'mapazi, kupweteka kwamalumikizidwe ndi malungo. Matendawa amatha kuyambitsidwa ndi zina monga matenda, matenda amthupi ndi khansa ndipo, nthawi zina, zimabweretsa zovuta monga kutuluka magazi.

Rheumatologist amayenera kufunsidwa ngati akuwakayikira ngati vasculitis, ndipo atha kuwonetsa echocardiogram kuti atsimikizire matendawa. Kuchiza kwa matendawa kumalimbikitsidwa ndi dokotala malinga ndi kuuma kwake ndi malo a kutupa kwa mitsempha. Onani mayeso ena omwe angachitike kuti mutsimikizire kupezeka kwa vasculitis ndi chithandizo chake.

3. Zozizwitsa

Zoyipa zimatha kuchitika chifukwa cha kuchuluka kwa kuthamanga komwe magazi amapita mumtsuko wamagazi, zomwe zimapangitsa kuti pakhale kutukusira kwa mtsempha kapena mtsempha wamagazi. Kuchulukaku kumatha kupezeka m'mitsempha yamagazi yamtima, ubongo kapena ziwalo za thupi, monga aorta m'mimba, mwachitsanzo.

Zizindikirozo zimadalira komwe kuli aneurysm, ndipo anthu omwe akuvutika ndi kusinthaku atha kukhala ndi ululu m'derali, zovuta kuyenda, kugwedezeka pamutu, kusawona bwino ngakhale kugwidwa ndipo ayenera kupita kuchipatala mwachangu. Onani zambiri zazikuluzikulu za ubongo ndi aortic aneurysm.

4. Kuzama kwa venous thrombosis

Kutsekula kwamitsempha yam'mimba ndizochitika zomwe zimachitika chifukwa cha kutsekeka kwa mtsempha wakuya mwendo, ntchafu kapena pamimba, kusokoneza magazi ndipo nthawi zambiri, kumayambitsa kutupa, kupweteka kwambiri komanso utoto wofiirira mwendo, mwachitsanzo.

Zina mwaziwopsezo zimakhudzana ndikuwoneka kwa thrombosis yoopsa ngati khansa, opaleshoni yayikulu, kugwiritsa ntchito njira zakulera zakumwa ndi kusuntha pang'ono kwa thupi, ndipo matendawa amapangidwa kudzera mu echocardiography. Nthawi zambiri, kuchipatala ndikofunikira kuchiza matendawa, omwe amatengera kugwiritsa ntchito mankhwala osokoneza bongo, monga heparin. Phunzirani momwe mungapewere thrombosis mwendo.

5. Aimpso mtsempha wamagazi stenosis

Mitsempha ya m'mitsempha yotchedwa renal artery stenosis imafotokozedwa ngati kuchepa kwa mitsempha yayikulu ya impso chifukwa cha mafuta, magazi kapena chotupa, ndipo kuzindikira kwa kusinthaku kumachitika kudzera m'mayeso monga angiography ndi aimpso Doppler.

Chithandizo cha aimpso mtsempha wamagazi stenosis chikuwonetsedwa ndi nephrologist ndipo chimakhala ndi catheterization, opareshoni ndikugwiritsa ntchito mankhwala a anticoagulant ndi thrombolytic. Nthawi zambiri, mankhwalawa amayenera kuchitidwa ndi munthu amene walandilidwa kuchipatala kuti alandire mankhwala kudzera mumitsempha ndipo ayenera kuyambitsidwa mwachangu kuti apewe zovuta monga pulmonary edema.
