TCD imikhumbi lobuchopho. Transcranial Doppler imikhumbi yobuchopho

Ikhanda kanye umsebenzi kuyehla yengqondo apho isizathu. Amaninzi, ezi mpawu kwenzeka izifo nemithambo. kwegazi kwi imithambo ngemithambo yobuchopho kukhokelela umonakalo kobuchopho. Kwiingozi ezimasikizi, ngenxa yokunqongophala kwe-oksijini kungadala istroke. Yinto eyaziwayo ukuba esi sifo anobungozi. disorder yegazi Acute nasezimpahleni yegazi ingqondo kukhokelela ekukhubazekeni, uphuhliso uxhuzula kwiimeko ezinzima kunokukhokelela ekufeni. hypoxia Chronic kwenzeka ngenxa ukuvala le mithambo ye kuphangwa kwemithambo atherosclerotic (umonakalo). Ngenxa yoko imisebenzi uyaphule efana inkumbulo, ulale, ubukrelekrele.

Ukuvavanya ejikeleza, wenze izitya ebuchotsheni TCD. Olu phando kuyimfuneko kwiimeko kukrokrelwa Encephalopathy discirculatory, stroke, imithambo okungaqhelekanga ngemithambo. Le nkqubo diagnostic ungaya phantse naluphi na eklinikhi.

TCD isifundo - yintoni

Kweli hlabathi siphila kulo akukho ezimbi ezininzi kwinkqubo luvo iindlela diagnostic. Njengoko isifundo ngasinye nyaka kwaphuculwa ndinciphe yingozi emzimbeni kwaye ulwazi ngakumbi. Iimfuno data ziyafikeleleka yi indlela noxilongo transcranial imithambo yegazi Doppler ebuchotsheni. Ngokusebenzisa esi sifundo sinako ukuqikelela kungekuphela nje imeko kwemithambo ngemithambo, kodwa ukuhamba kwegazi ngaphakathi kubo. I TCD usekelwe indlela cuke diagnostic. Le ndlela sikuko ukuba icebo uyakwazi ukufaka imiyalezo echo sasivela erythrocytes. Emva olu lwazi siboniswe esweni oludityaniswe woluvo.

Nala izixhobo ugqirha kubhekwe imilo kunye nendawo kweenqanawa, imeko yabo ye-mafutha, icala aya kwegazi. Ezi data ixabiso elikhulu diagnostic, ekubeni abavumela ukuba bagwebe ubukho ezimbi ezifana Encephalopathy, malformation, kwemithambo, stroke. Ezi zifo zinkulu ngokwentlalo, njengoko kukukhokelela nokukhubazeka. Ngoko ke, kwiimeko TCD efanayo iinqanawa palsy pathology okukrokrelwayo ukuba indlela kunyanzelekile diagnostic. Uphononongo ikhuselekile umzimba kwaye ulwazi kakhulu.

Ubungqina obubonakalayo buxela ukuba Doppler trankranialnoy

iimviwo Doplerography kweenqanawa ingqondo kunye entanyeni lwenziwa kwimeko kwezigulane, ekubeni indlela isongelwa diagnostic. Kuyinto elula ngokupheleleyo kwaye ikhuselekile. TCD ke ezingahambi sesichengeni sosasazeko lwemitha emzimbeni yomguli kunye nogqirha. Ubungqina obubonakalayo buxela ukuba imithambo yegazi Doppler entanyeni kunye nentloko berhanelwa olwaphula yokumpompoza kwegazi kunye licuthe kwemithambo okanye yegazi. Olunjalo utshintsho zibonisa izifo semithambo, apho ulawulo lomgadi ugqirha kunye nonyango iimfuno. Ubungqina obubonakalayo buxela ukuba Doppler:

1. izifo Acute ejikeleza ebuchotsheni. Ezi ziquka sophele nobetho kobuchopho, kwakunye nemeko phambi stroke.
2. Yamafutha kwemithambo entanyeni kunye nentloko. Xa esi sifo a licuthe le mithambo kwemithambo yegazi ngenxa yokuba kule endothelium ukuze yande uzaleke ezityebileyo - umonakalo cholesterol.
3. Encephalopathy. Oku kwenzeka ngokuchasene nemvelaphi hypoxia ezigulo ezondeleyo. DEP bangaba nje ngenxa yegazi kunye osteoarthritis. Kwiimeko kakhulu kukhokelela sengqondo esixhalabisayo.
4. malformation yegazi. Libhekisela mgaqweni iziphene kwaye na indawo ephosakeleyo kwaye uqhagamshelwano lwe emithanjeni kunye nenkqubo lwemithambo.
5. entanyeni semithambo kwemithambo kunye nentloko, kwakunye ukunyuka koxinzelelo lwegazi.

TCD kufuneka kwenziwe kuphela bethengisa esi sifo, kodwa ukuba zikhona. Kuyimfuneko ukuba ukuvavanya esweni konyango.

Iinketho ze Doppler transcranial

iimviwo Doplerography kweenqanawa ingqondo nentamo kungenziwa ngeendlela ezahlukeneyo. Ukukhetha indlela kuxhomekeke iimpawu sifo. Ngokusekelwe mfanekiso lwezonyango, ugqirha uyakwazi sokukrokrela kwasendaweni benqanawa achaphazelekayo. Yaba iinguqulelo 3 zophando:

1. Carotid ultrasonography - kwenziwa xa umisela woluvo ezityeni zangaphandle entanyeni. Njengoko kwemithambo carotid iwukhulise iimpahla palsy, olu phando lunika lobukho okanye ukungabikho ischemia ebuchotsheni. Ubungqina obubonakalayo buxela Abatyhafileyo, ukulahlekelwa inkumbulo, zizigulo zemithambo.
2. TCD izitya ebuchotsheni - isixhobo esifakelwe ezayo kwemithambo ezinkulu lobuchopho. Nokufikelela ziqikelela karhulumente transcranial ebuchotsheni. Siye sifunde zezomzuzwana, Occipital nemimandla nezenyama.
3. Transorbital ayisuse. Eyenziwa kwiimeko neempahla iinguqu amehlo okusolwayo.

Izimo ukuba TCD

Inzuzo ephambili iinqanawa yobuchopho TCD kukuba uphando ikhuselekile ukuba umzimba. Kunokuba enze izigulane ezingabantwana, abasetyhini abakhulelweyo kunye nabantu abanengxaki ezimbi ezingapheliyo. Izimo ngokuba Doppler transcranial ayikho. Kunjalo, akukho enqwenelekayo ukwenza kuhlaselo nokoyika ukusilela ezesifuba zokuphefumla.

Ukulungiselela kwemithambo TCD ngemithambo intloko nentamo

Doppler ultrasound kwemithambo entloko yaye intamo ezingahambi neziphumo eziyingozi kwaye elula. Ngoko ke, ukulungiselela i-TCD ikhethwa. Ingakumbi izigulane bayathatheka kufuneka acacise injongo yale nkqubo. Nadlamkisayo ingavezwa njengoba kulungiselelwa. Phambi kokuba inkqubo, kufuneka ukususa izacholo kwaye ukucoca ifowuni ephathwayo.

enza izixhobo kuhlolwa

Doppler Transcranial lwenziwa isigulane ehleli esitulweni. Nalo ufikelelo olwenziwa kabini okanye ayisuse-ntathu. Le woluvo cuke bunikwa ngokunxulumene ukuya endlebeni. Le isifundo ngaphambili, ngoko ke isixhobo isusiwe phezulu (kummandla zexeshana kunye Parietal), emva koko - eyadlulayo. Oku kukuvumela ukuba ukuhlola igazi flow kuzo zonke iinkalo ebuchotsheni. Ekupheleni ukufunda, woluvo ibekwe entanyeni. Ngoko ke kunokwenzeka ukuba bagwebe imeko cerebellar zone umthambo ka Galen kunye Rosenthal. Kwakhona ngexesha scan transcranial kuhlolwa imo kwemithambo vertebral.

TCD iimpahla ebuchotsheni: Iziphumo zokucazulula

iimpahla Iziphumo TCD ivavanywa ugqirha-time real of kuxilongo ezisebenzayo. Ngenxa yokuba lo mfanekiso kuza phezu kwekhusi, yingcali nako ukufikelela kwizigqibo malunga nemeko kwemithambo okanye yegazi. Xa iimpahla ayisuse ntathu ukuba zipeyintwe obomvu, kunye noblowu. Inika isalathisi malunga impefumlelwano inkqubo lwemithambo kunye umfutho. Ngenxa TCD uyakwazi nokuvavanya Velocity zibaleke igazi ezityeni, indlela yaso. Doppler nayo ibonisa izixhobo vana likarhulumente, neendonga yangaphakathi kwemithambo. flow kwegazi Slow okanye sophazamiseko abonisa licuthe le sayo isitya. Kulo mzekelo, kufuneka udibane luvo kunye yingcibi nemithambo.

Zeziphi iikliniki ukwenza TCD

Ukuba urhanela ukuba ukuphazamiseka nemithambo luvo phantse lisoloko libhekisela izigulane ukuya TCD izitya lobuchopho. Phi na phando? Ukukhetha ekliniki aluchaphazeli ngenxa inkqubo, ngoko ke isigulane isigqibo: ukwenza le nkqubo kuyo nayiphi na indawo. TCD lwenziwa kumaziko onyango phantse yonke ihlawulwe kunye iikliniki inkangeleko ngokubanzi kunye isebe kuxilongo ezisebenzayo.
