Transcranial Doppler ultrasound

Transcranial doppler ultrasound (TCD) yog kev kuaj mob. Nws ntsuas ntshav ntws mus rau thiab hauv lub hlwb.

TCD siv lub suab nrov los tsim cov duab ntawm cov ntshav ntws hauv lub hlwb.

Nov yog qhov kev sim ua:

• Koj yuav pw saum koj sab nraub qaum nrog koj lub taub hau thiab caj dab hauv ncoo. Koj lub caj dab ncab me ntsis. Lossis koj tuaj yeem zaum ntawm ib lub rooj zaum.
• Tus kws tshaj lij siv cov dej pleev pleev rau hauv koj lub tuam tsev thiab tawv muag, hauv qab koj lub puab tsaig, thiab hauv qab ntawm koj lub caj dab. Cov dej hiav txwv pab lub suab ntab tawm hauv koj cov ntaub so ntswg.
• Ib qho wand, hu ua transducer, tau txav mus thaj chaw raug sim. Qhov wand xa tawm cov suab vuag. Lub suab nrov mus los ntawm koj lub cev thiab rov qab tawm ntawm thaj chaw uas tau kawm (hauv qhov no, koj lub hlwb thiab cov hlab ntsha).
• Lub koos pis tawj saib cov qauv uas lub suab sib txuam tsim thaum lawv rov qab rovqab. Nws tsim cov duab los ntawm cov suab nrov. Doppler tsim lub suab "zaws", uas yog lub suab ntawm koj cov ntshav txav los ntawm cov hlab ntsha thiab leeg ntshav.
• Qhov kev kuaj mob tuaj yeem siv sijhawm li 30 feeb txog 1 teev kom tiav.

Tsis muaj kev npaj tshwj xeeb yog xav tau rau qhov kev ntsuas no. Koj tsis tas yuav hloov mus rau hauv kev hnav tsoos tsho.

Nco ntsoov:

• Tshem cov iav ntsiab muag ua ntej ntsuas yog tias koj coj lawv.
• Khaws koj ob lub qhov muag thaum gel raug rau koj daim tawv muag yog li koj tsis txhob pom nws hauv koj lub qhov muag.

Cov gel yuav hnov ​​txias rau ntawm koj cov tawv nqaij. Koj tuaj yeem hnov ​​qee qhov siab vim tias lub tshuab hloov mus ib ncig ntawm koj lub taub hau thiab caj dab. Lub siab yuav tsum tsis txhob ua kom muaj mob. Koj kuj tuaj yeem hnov ​​lub suab "whooshing". Qhov no yog qhov qub.

Kev ntsuam xyuas yog ua tiav los txhawm rau txhawm rau kuaj mob uas cuam tshuam rau ntshav ntws mus rau lub hlwb:

• Nqaim lossis txhaws ntawm cov hlab ntsha hauv lub hlwb
• Mob stroke lossis cov ischemic nres (TIA lossis ministroke)
• Los ntshav hauv qhov chaw nruab nrab ntawm lub hlwb thiab cov ntaub so ntswg uas npog lub hlwb (subarachnoid hemorrhage)
• Cov pob roj ntawm cov hlab ntsha hauv lub hlwb (cerebral aneurysm)
• Pauv hauv siab hauv pob txha taub hau (intracranial siab)
• Sickle cell anemia, txhawm rau txheeb xyuas kev pheej hmoo mob stroke

Daim ntawv tshaj qhia ib txwm qhia pom tseeb cov ntshav ntws mus rau lub hlwb. Tsis muaj qhov nqaim lossis txhaws hauv cov hlab ntshav uas ua rau thiab nyob hauv lub hlwb.

Qhov tshwm sim txawv txav txhais tau hais tias cov leeg ntshav tau nqaim lossis qee yam hloov pauv ntshav kev khiav hauv cov hlab ntsha ntawm lub hlwb.

Nws tsis muaj kev pheej hmoo nrog kev ua tus txheej txheem no.
