Sesebelisoa sa Transcranial Doppler

Transcranial doppler ultrasound (TCD) ke tlhahlobo ea tlhahlobo. E metha phallo ea mali ho ea le kahare ho bokong.

TCD e sebelisa maqhubu a molumo ho etsa litšoantšo tsa phallo ea mali kahare ho boko.

Tsela eo teko e etsoang ka eona ke ena:

• U tla robala ka mokokotlo tafoleng e nang le marulelo hloohong le molaleng mosamong. Molala oa hau o otlolohile hanyane. Kapa u ka lula setulong.
• Setsebi se tlotsa gel e nang le metsi litempeleng tsa hao le mahlo a mahlo, tlas'a mohlahare oa hau, le botlaaseng ba molala oa hau. Jel e thusa maqhubu a molumo ho kena liseleng tsa hau.
• Leqhubu, le bitsoang transducer, le tsamaisoa sebakeng se lekiloeng. Leqhubu le romela maqhubu a molumo. Maqhubu a molumo a pholletsa le 'mele oa hau' me a fofa sebakeng seo ho ithutoang ho sona (ntlheng ena, boko ba hao le methapo ea mali).
• K'homphieutha e sheba mokhoa oo maqhubu a molumo ao etsang ha a khutlela morao. E etsa setšoantšo ho tloha maqhubu a molumo. Doppler e etsa modumo wa "swishing", e leng modumo wa madi a hao a tsamayang hara methapo le methapong.
• Teko e ka nka metsotso e 30 ho isa ho hora e le 1 ho phethela.

Ha ho boitokiso bo khethehileng bo hlokahalang bakeng sa tlhahlobo ena. Ha ho hlokahale hore u fetole seaparo sa bongaka.

Hopola ho:

• Tlosa lilense tsa puisano pele ho tlhahlobo haeba u li apara.
• Boloka mahlo a hau a koetsoe ha gel e sebelisoa linthong tsa hao e le hore u se ke ua e fumana mahlong a hau.

Gel e ka 'na ea ikutloa e bata serung sa hao. U kanna oa utloa khatello ha transducer e ntse e tsamaisoa ho potoloha hlooho le molala. Khatello ha ea lokela ho baka bohloko. U kanna oa utloa molumo oa "whooshing". Sena se tloaelehile.

Teko e etsoa ho fumana maemo a amang phallo ea mali bokong:

• Ho fokotsa kapa ho thiba methapo bokong
• Stroke kapa tlhaselo ea ischemic ea nakoana (TIA kapa ministerroke)
• Ho tsoa mali sebakeng se pakeng tsa boko le lisele tse koahelang boko (subarachnoid hemorrhage)
• Ballooning ea sejana sa mali bokong (cerebral aneurysm)
• Fetola khatello kahare ea lehata (khatello e sa sebetseng)
• Sickle cell anemia, ho lekola kotsi ea stroke

Tlaleho e tloaelehileng e bonts'a phallo e tloaelehileng ea mali bokong. Ha ho na ho fokotseha kapa ho thiba ha methapo ea mali e lebisang bokong le kahare ho eona.

Sephetho se sa tloaelehang se bolela hore mothapo o ka fokotsoa kapa ho na le ho hong ho fetolang phallo ea mali methapong ea boko.

Ha ho na likotsi ka ho ba le ts'ebetso ena.
