Imithambo yegazi Doppler ebuchotsheni kunye nentamo. Yintoni Doppler (Doppler ultrasound)?

Le nomphumela, ezifana intloko ebuhlungu, abazaziyo bonke. Amaxesha amaninzi isizathu ukwenzeka yalo isifo semithambo. Kwiimeko ezininzi, ukuba baphuhlise ebudaleni phakathi nabadala. Ngenxa kwegazi zaneleyo engqondweni ukuphuhlisa iimpawu ischemia. Ezi ziquka: memory ongaboniyo, umthamo umsebenzi yancitshiswa, ukuphazamiseka kokulala. Ukuxilonga ischemia, wenza Doppler izitya ingqondo nentamo (ultrasonography). Phakathi kwabo, imithambo ezinkulu ngemithambo, ukuthatha imvelaphi yalo ukusuka Arch aortic. Okwangoku, Doppler ultrasound lwenziwa phantse kuzo zonke izibhedlele. Olu phando ayikho yingozi empilweni kunye ebelapha.

Yintoni na imithambo yegazi Doppler?

Doppler ultrasound (Doppler ultrasound) olwenziwa ngenxa yegazi okanye imithambo. Kaninzi, ngenxa kule ndlela ukufumanisa isifo semithambo kweqondo ezisezantsi neziphezulu kwakunye njengentloko kunye nentamo. Olu phando enokwenziwa kwizigulane na ubudala. Izimo Doppler ukuba phantse azikho kwaukubakho. Oku kungenziwa iintsana kunye nabasetyhini abakhulelweyo. igazi Doppler iimpahla ingqondo kunye nentamo - kukho iindlela negalelo ngokusekelwe nokuzimisela yokumpompoza kwegazi Velocity. Ngale nkqubo diagnostic uyakwazi ukubona imithambo nqa ngayo ngemithambo, izinga licuthe le mithambo.

Doppler: ngumongo indlela

Ekuqeshweni indlela loxilongo, izigulane zinomdla: "? Yintoni Doppler". Nceda uqaphele ukuba le nkqubo kuyimfuneko ukuhlola imeko iimpahla. YoLungiso-sandi lweSihambisi kwenziwa kubanjiswene ne-ultrasound (ultrasonography). ingafunyanwa ngokusebenzisa Doppler:

1. Isantya icala aya kwegazi. Ngokufuthi ezimbi kwemithambo ngemithambo bewubhiyozela kuyehla okanye ngesantya, twist.
2. imeko yegazi. Ngenxa ekuphazamiseni le mithambo ixhomekeke imithambo ultrasonography okanye imithambo neplaque atherosclerotic, thrombus, njalo njalo. D. Ukongeza, le ndlela ivumela sibone ubuthathaka ivelufa olujikeleza.

Kakuhle eli phando ukuze kusekwe emithanjeni okanye inkqubo lwemithambo. Lo mfanekiso ngexesha elifanayo kuvela esweni. Ukwahlula engayi kunye scan ntathu nemithambo. Ezininzi kwinguqulelo yokuqala ilawula ukuhlola imeko endothelium kunye mithambo kwemithambo entloko kunye nentamo. ayisuse ntathu nzima ngakumbi. Ngoncedo lwe umfanekiso umbala olujikeleza. Oku kuphucula ngeso kwakunye kwenza kube lula ukuba ukuhlola imeko yokumpompoza kwegazi.

Iindlela Doppler

UZDG (olujikeleza Doppler) lasentloko kunye nentamo lwenziwa ngeendlela ezininzi. Ngamnye kubo sisebenzayo izifo ezithile. Khetha indlela Doppler kuxhomekeke kuhlobo site semithambo ukuba kuphandwe. Utsho bodwa:

1. ultrasonography Carotid. Ngoko usebenzisa isixhobo okhethekileyo abahlola iimpahla entanyeni. Le ndlela iMifanekiso kakhulu eqhelekileyo. Lusetyenziswa kwiimeko kwezifo kukrokrelwa luvo ezinxulumene amandla engqondo ayonelanga. iimpahla intamo ebekwe yokuzenzisa, inkulu kubo - nto imithambo carotid. ultrasonography Carotid abonisa ukuba nesiyezi, niphele, ulale abahluphekileyo inkumbulo, iimpawu luvo.
2. engayi ukuskena Transcranial. Woluvo ise kwimimandla Occipital, zexeshana kunye temporal. Ngale ndlela, intloko ibanjelwe Doppler. Ngale ndlela uphando, ngaphambili, ngasemva, phakathi kunye umthambo vertebral. Kwakhona, ngendlela efanayo, unako ukuhlola imeko sinus ngqo, umthambo ka Galen kunye Rosenthal.
3. Transorbital ayisuse. Le woluvo ukhwele ijwabu eliphezulu. Nalo ufikelelo ukuhlola igazi flow kwi supratrochlear kunye yegazi lwamehlo.

Ubungqina obubonakalayo buxela ukuba Doppler

Doppler semithambo ebuchotsheni nentamo lwenziwa ejikelezayo kakuhle okukrokrelwayo. ischemia Chronic kuboniswa iimpawu ezifana memory ongaboniyo, ulale, engqondweni nokuphazamiseka luvo. Ziziphazamiso zosulele nemithambo basenokuba ukuxhuzula, ilahleko osezingqondweni, paresis okanye ukushwabana imilenze. Kukho Yayibubungqina zilandelayo Doppler ultrasound kwemithambo entloko nentamo:

1. Kobuchopho.
2. Stroke.
3. Encephalopathy.
4. Imeko emva stroke oyingozi.
5. Kukrokrelwa okanye kwemithambo, malformation nemithambo.
6. Isiyezi kunye niphele of umyalezo ezingaziwayo.
7. Osteochondrosis yomqolo wesibeleko.
8. Kwegazi.
9. ongaboniyo: hemianopsia, diplopia, ukuvela iinkomo.

Doppler ultrasound ekukhulelweni akukho contraindicated. Kwezinye iimeko, le ndlela lophando emiselweyo kwiimeko zokugxojwa ekucingelwa kwegazi placental. Doppler ultrasound imithambo yegazi yobuchopho kunye nentamo abasetyhini abakhulelweyo kuqhutywa phambi ezimbi ngasentla.

Kwezinye iimeko, Doppler ultrasound contraindicated?

Inzuzo ephambili Doppler ultrasound kucingwa kukungabikho Izimo ukuba baqhube uphando. Enyanisweni, ultrasonography kukuba ngokupheleleyo inkqubo engenabungozi. It zingenziwa nanini na ubudala, nkqu phambi nezifo ezingapheliyo. Noko kunjalo, kukho iimeko apho ayikhuthazwa ukwenza Doppler. Kuba Izimo isihlobo ziquka iimeko kakhulu phantsi apho isigulana kunzima ukuba ngokuxwesileyo. Oku kwenzeka ngexesha isiqephu kwimiqobo inyumoniya (COPD, isifuba), igazi etsolo kunye nokungaphumeleli zokuphefumla.

Amalungiselelo imithambo yegazi Doppler entloko nentamo

Doppler iimpahla yegazi ingqondo entanyeni kwaye ayifuni uqeqesho olulodwa. Noko ke, ngaphambi kokuba enze olu phando, ikhutshwa phandle uxilongo elebhu. Xa uphethe izigulane izikhalazo yintloko ebuhlungu, ukuphazamiseka ekulaleni, umbono, memory ongaboniyo, ikakhulu hlalutyo lululo amisiweyo. Phakathi kwabo - i-pat, OAM, ngamachiza kwe coagulation kwegazi. Ukuba data laboratory musa ukubonisa unobangela ezi mpawu, kuyimfuneko ukuba baqhube izitya Doppler ultrasound entanyeni kunye nentloko. kufuneka asuse izivatho phambi kokwenza Doppler. Indlela diagnostic le ezingahambi umthwalo iphiramidi ebonisa kwi eziphilayo. Ukuba ufuna Doppler ngexesha lokukhulelwa, kuyimfuneko ukuba achaze kumfazi inkqubo ayikho kuyingozi olungekazalwa.

equipment survey

Kungakhathaliseki ezikhethiweyo lokufikelela, isikhundla nomonde - engqengqe ngomqolo. Xa ultrasonography carotid, vula intloko ekunene okanye ekhohlo, siphoswe umva kancinane. Woluvo ifakiwe kule ndawo iinqanawa ezinkulu kunye naphakathi. Ngaphambi kokuqhubeka sifundo, intamo lubricated umphezulu ive gel eyimfuneko ngokokushiyana lesixhobo kunye nokuphucula nokuthelekelela. Emva koko, ifowuni isusiwe phezu eluswini, lo gama i-screen uboniswa umfanekiso kwemithambo ngemithambo.

Kwiinqanawa transcranial ukukrwaqula wabancina kabini kunye ntathu ibekwe kwisisu cranial nangaphezulu. Ukuze benze oku, isigulane ucelwa ukuba uhlale up. Ukuvavanya imeko woluvo kwemithambo yobuchopho kuqala zibekwe ngaphambili, uze emva koko - ukusuka phezulu emva indlebe. Uphando ngqo sinus umthambo Rosenthal kunye Galena parabazilyarnye kunye imithambo yegazi cerebellar inokuba ngokushukumisa isixhobo kummandla Occipital. Yiba nomfanekiso kwemithambo vertebral ngeendlela ezimbini: ngokusebenzisa scan sonography transcranial okanye carotid.

Uphononongo amalungu ezinemigca lwenziwa kwindawo lisalele. Kulo mzekelo, iinkophe isigulane kufuneka zivalwe. Ukongeza, ngoncedo lokufikelela transorbital libonwa elizenzekelayo Umthambo carotid lwangaphakathi.

imithambo yegazi Iziphumo Doppler entloko nentamo

Emva kophando kuyimfuneko ukuvavanya iziphumo kwaye uthelekise ezi data kunye eqhelekileyo. Carotid ultrasonography eyenziwa ukuvavanya iimilo iimpahla, indawo yabo, ubukhulu kunye nemeko le mithambo. Ukuqikelela ukuzala kwaye iSystolic nencopho Velocity igazi flow kwi imithambo carotid. Ngokuqhelekileyo, kufuneka ingadluli 0.9. Ukuba lo mzobo asondele 1.5, ngoko ke le mithambo isithintelo yi malunga ne-50%. Velocity peak aluqinisekiswa obturation kwemithambo ezipheleleyo (elingana no0). Loo urhulumente yenzeka thrombosis okanye Embolism benqanawa kwaye kunokukhokelela ekufeni. Ukuvala kubonakala yegazi. Esi sifo kuqhelekile kubantu abadala kwaye kaninzi unobangela olujikeleza Encephalopathy kunye stroke oyingozi.

Xa untlu-ntathu umbala ukukrwaqula, ukongeza parameters zingentla zibalwa utshintsho kunokwenzeka flow kwegazi (uqina, indlela). Kungenzeka kwakhona ukuba nomfanekiso iqondo yokuzalisa lemigqomo. Ukuze ufumane inkcazelo malunga ubuthathaka kwemithambo lwemithambo zingafumaneka ngokuthi zokwenza uvavanyo ezisebenzayo (kukucela isigulane ukuba ithamo, ukutshintsha indawo emzimbeni).

Doppler ultrasound iimpahla entloko nentamo: ixabiso le nkqubo

Doppler lwenziwa kwizibhedlele ezininzi,-ofisi okanye nekhabhathi ukuba uxilongo ezisebenzayo. Ngaphambi kokuba le saveyi, kufuneka pre-ubhalise kwi izitya ultrasound Doppler lasentloko kunye nentamo. Ixabiso le nkqubo iya kuxhomekeka ukukhethwa ekliniki. Kwi-avareji, oko 2300-3500 engange. Uyacetyiswa ukuba baphumeze ulwalathiso zophando. Kwezinye iikliniki, imithambo yegazi Doppler entanyeni kunye nentloko kwenziwa ngabanye kunye. Kwi oku kuxhomekeke ixabiso. iimpahla Iindleko UZDG entanyeni (okanye intloko) kukuba ukususela 1100 ukuya 1800 engange.

Doctors malunga Doppler

Ngokutsho oogqirha, imithambo Doppler ultrasound umgangatho uxilongo kwezifo ebuchotsheni. Izinto eziluncedo yale ndlela ngonqabiseko kunye nolwazi eliphezulu umxholo wayo. Ukongeza, akukho Izimo ukuze ultrasonography. St. Petersburg (St. Petersburg) - isixeko apho kukho iikliniki ezininzi exhotyiswe X-ray uxilongo nekhabhathi. imithambo yegazi Doppler lasentloko, nentamo kungenziwa kumaziko ezempilo, "Lahti" MEDEM, "Energy", "ixesha elide", njalo-njalo ..
