Izitsha Doppler igazi zobuchopho nentamo. Kuyini Doppler (Doppler ultrasound)?

Lokhu uphawu, ezifana ikhanda, ajwayelekile kubo bonke. Ngokuvamile isizathu nesenzakalo kwakhona isifo semithambo. Ezimweni eziningi, ziba e yobudala emaphakathi futhi ubudala. Ngenxa enganele igazi ebuchosheni ukuthuthukisa izimpawu ischemia. Lezi zihlanganisa: inkumbulo ukungakhuli, ukuvilapha, ukuphazamiseka kokulala. Ukuxilonga ischemia, wenziwa Doppler izitsha ubuchopho nomqala (ultrasonography). Phakathi kwabo, imithambo ezinkulu kanye emithanjeni, ukuthatha ivelaphi kusukela lwaleli yomthambo i-aorta. Okwamanje, Doppler ultrasound wenziwa cishe kuzo zonke izibhedlela. Lolu cwaningo akulona ingozi empilweni kanye nabuhlungu.

Kuyini izitsha Doppler igazi?

Doppler ultrasound (Doppler ultrasound) Ucwaningo olwenziwa i-emithanjeni noma imithambo. Ngokuvamile, sibonga le ndlela, ukuhlola isifo semithambo we ephansi kanye engenhla emikhawulweni kanye ikhanda nentamo. Lolu cwaningo kungenziwa kwenziwe iziguli zanoma iyiphi iminyaka. Doppler contraindications cishe non-akukho. It kungenziwa izingane nabesifazane abakhulelwe. Doppler igazi izitsha ubuchopho nomqala - kuyinto izindlela wezinsimbi esekelwe ukuzimisela ukugeleza kwegazi velocity. Nale nenqubo ethile yokuthola isifo kungathola imithambo amazed kanjani futhi imithambo degree of ukuvaleka mafutha anciphisa isikhala esingaphakathi.

Doppler: ngokuyisisekelo indlela

Ekumisweni indlela ukuxilongwa, iziguli unesithakazelo: "? Uyini Doppler". Sicela uqaphele ukuthi le nqubo kuyadingeka ukuhlola isimo izitsha. Isilawuli Samandla kwenziwa ngokuhlanganyela ultrasound (ultrasonography). kungatholakala besebenzisa Doppler:

1. Ijubane nesiqondiso ukugeleza kwegazi. Ngokuvamile e pathologies kwemithambo yegazi kanye emithanjeni waphawula ke ingasheshi noma ugijima ngesivinini, twist.
2. isimo semithambo. Ngenxa ukuvimbela mafutha anciphisa isikhala esingaphakathi kunqunywa ultrasonography imithambo noma ngemithambo qwembe atherosclerotic, thrombus, nokunye. D. Ngaphezu kwalokho, le ndlela kusivumela ukunquma nobuthakathaka valve isimiso semithambo yegazi.

Ingqikithi cwaningo iwukuba scan lwemithambo noma uhlelo emithambo yegazi. Isithombe ngesikhathi esifanayo kuvela qapha. Hlukanisa Duplex futhi eyisitezi scan semithambo. In the version wokuqala ephethe ukuhlola isimo endothelium futhi mafutha anciphisa isikhala esingaphakathi kwemithambo yegazi we ikhanda nentamo. ukuskena eyisitezi nzima. Ngosizo isithombe umbala isimiso semithambo yegazi. Lokhu kuthuthukisa ngeso kanye kwenza kube nokwenzeka ukuba bahlole isimo ukugeleza kwegazi.

Izindlela Doppler

UZDG (semithambo Doppler) we ikhanda nentamo uqhutshwa ngezindlela eziningana. Ngamunye wabo siyasebenza kule izifo ezithile. Khetha indlela Doppler incike onjani indawo semithambo kumele iphenywe. isehlane Ngakho:

1. ultrasonography Carotid. usebenzisa ithuluzi ekhethekile Ngakho wahlola izitsha entanyeni. Le ndlela ezithwetshuliwe ezivamile. Isetshenziselwa ezimeni esolwa izifo zezinzwa elihlobene ne enganele amandla ubuchopho. izitsha entanyeni elise yokuzenzisa, esikhulu kunazo zonke kubo - kungcono imithambo carotid. ultrasonography Carotid kuboniswa ngenxa isiyezi, yokufikelwa, ubuthongo ompofu kanye inkumbulo, izimpawu zokungasebenzi kahle kwemizwa.
2. Transcranial Duplex ukuskena. Inzwa itholakala ezindaweni occipital, yesikhashana futhi yesikhashana. Ngale ndlela, ikhanda labetibambile Doppler. Nale ndlela uphenyo, ngaphambili, ngemuva, phakathi futhi Umthambo vertebral. Futhi, ngendlela efanayo, ungakwazi ukuhlola isimo itheku oqondile, umthambo ka uGalen no Rosenthal.
3. Transorbital ukuskena. Inzwa ogibele leso elingenhla. Nale ukufinyelela ukuhlola igazi flow supratrochlear nokuvaleka kwemithambo amehlo.

Izimpawu I-Doppler

Doppler semithambo cerebral nentamo lwenziwa esolwa kwegazi kahle. ischemia Okungalapheki livezwa izimpawu ezifana inkumbulo ukungakhuli, ubuthongo, engokwengqondo iziyaluyalu zezinzwa. Ngo-acute thuthuva semithambo angagcina sokuwa nokulahlekelwa ukwazi, paresis noma ukukhubazeka yezingalo nemilenze. Kukhona izimpawu ezilandelayo ukuze Doppler ultrasound imithambo ye ikhanda nentamo:

1. Zesikhashana kuhlasela ischemic.
2. Stroke.
3. Encephalopathy.
4. Isimo emva unhlangothi oyingozi.
5. Okusolwayo noma useshonile, malformation semithambo.
6. Isiyezi nokuquleka of omsakazo engaziwa.
7. Osteochondrosis yomgogodla wesibeletho.
8. Umfutho ophakeme wegazi.
9. Visual ukungakhuli: hemianopsia, diplopia, ukubukeka izinkomo.

Doppler ultrasound ekukhulelweni is hhayi contraindicated. Kwezinye izimo, le ndlela yocwaningo ezinqunyiwe ezimeni ukwephulwa esolwa ukuzungeza esinomhlapho. Doppler ultrasound emithanjeni yegazi zobuchopho nentamo abesifazane abakhulelwe iqhutshwe ebukhoneni pathologies ngenhla.

Kwezinye izimo, Doppler ultrasound is contraindicated?

Inzuzo enkulu Doppler ultrasound kubhekwa ukungabi khona Izimo ukuqhuba ucwaningo. Eqinisweni, ultrasonography nhlobo inqubo engenangozi. Kungaba kwenziwe ngasiphi yobudala, ngisho khona izifo. Noma kunjalo, kuba khona it is hhayi Kunconywa ukuba enze Doppler. Ukuze Izimo isihlobo zihlanganisa izimo ezinzima isiguli ngaphansi okuyinto nzima sesimweni ovundlile. Lokhu kungenzeka ngesikhathi isiqeshana isimiso bronchial (COPD, isifuba somoya), inhliziyo acute nokuvaleka kwemigudu yokuphefumula.

Ukulungiselela izitsha Doppler igazi ikhanda nentamo

Doppler izitsha ubuchopho igazi entanyeni futhi ayidingi ukuqeqeshwa okukhethekile. Nokho, ngaphambi kokuba bafeze lo cwaningo, kwenziwe ukuhlola i-laboratory. Uma usingatha iziguli izikhalo ikhanda, ukuphazamiseka kokulala, umbono, inkumbulo ukungakhuli, ngokuyinhloko ihlaziya esimisiwe. Phakathi kwabo - the Kla, OAM, biochemistry igazi coagulation. Uma idatha laboratory ayibonisi imbangela yalezi zimpawu, kubalulekile ukuqhuba izitsha Doppler ultrasound entanyeni ekhanda. kumelwe ususe ubucwebe ngaphambi kokwenza Doppler. Indlela zokuxilonga akuyona ephelezelwa umthwalo osabalalayo ku umzimba. Uma ufuna Doppler ngesikhathi sokukhulelwa, kubalulekile ukuchaza kowesifazane ukuthi inqubo ingozi embungwini.

Isisetshenziswa inhlolovo

Kungakhathaliseki kukhethwa ukufinyelela, isikhundla nesineke - elele emhlane wakhe. Lapho ultrasonography carotid, nenhloko niye kwesokunene noma kwesobunxele, siyiphonse emuva kancane. Inzwa efakwe kule indawo imikhumbi emikhulu kanye naphakathi. Ngaphambi kokuqhubeka cwaningo, intamo nivame ebusweni acoustic gel ezidingekayo ngokuhambisa zedivayisi futhi sithuthukise ngeso. Ngemva kwalokho, idivayisi uhambe phezu kwe isikhumba, ngenkathi isikrini ubonisa isithombe kwemithambo yegazi kanye emithanjeni.

Ngo Duplex futhi eyisitezi ukuskena wahlola izitsha transcranial etholakala ngaphakathi komgodi cranial nangale. Ukuze wenze lokhu, isiguli uyabuzwa nokuhlala. Ukuze ukuhlola isimo cerebral imithambo inzwa lokuqala ibekwe phambi, bese - kwaphezulu futhi ngemuva kwendlebe. Ukuphenywa ngqo itheku umthambo Rosenthal futhi Galena parabazilyarnye kakhulu futhi imithambo yegazi cerebellar kungaba yokuhamba kudivayisi esifundeni occipital. Ake usibone ngeso lengqondo umfula vertebral ngezindlela ezimbili: esebenzisa transcranial sonography scan noma carotid.

Lolu cwaningo kwezitho semithambo wenziwa isikhundla lisalele. Kulokhu, nezinkophe lesiguli kufanele ivalwe. Ngaphezu kwalokho, ngosizo ukufinyelela transorbital ibukeke elizenzekelayo yangaphakathi carotid Umthambo.

izitsha Ezenye Doppler igazi ikhanda nentamo

Ngemva uphenyo kuyadingeka ukuhlola imiphumela kanye ukuqhathanisa lezi ngedatha kuyinsakavukela. Carotid ultrasonography kwenziwe ukuhlola Umumo nemikhumbi, indawo yabo, ukujiya kanye isimo mafutha anciphisa isikhala esingaphakathi. Futhi ukunquma diastolic futhi systolic isiqongo Isivinini kwegazi flow imithambo carotid. Ngokuvamile, kufanele singadluli 0.9. Uma lesi sibalo eduze 1.5, mafutha anciphisa isikhala esingaphakathi izivimbelo ke imayelana 50%. Isivinini isiqongo akunqunywa ngesikhathi umnyuziki obturation Umthambo (elingana no-0). isimo esinjalo kwenzeka thrombosis noma embolism bomkhumbi futhi lingaholela ekufeni. Ukuvaleka kubonakala isifo sokuqina kwemithambo yegazi. Lesisifo evamile kubantu asebekhulile futhi ngokuvamile imbangela semithambo encephalopathy futhi unhlangothi oyingozi.

Ngezinye Duplex noma eyisitezi umbala ukuskena, ngaphezu kwemigomo ngenhla kulinganiswa izinguquko kungenzeka e ukugeleza kwegazi (velocity, isiqondiso). Kungenzeka futhi ukubona ngehlo lengqondo i degree yokugcwalisa ye ezitsheni. Ukuze uthole ulwazi mayelana ngobuthakathaka valve emithambo yegazi ingatholakala ngokufeza ukuhlolwa obusebenzayo (buza isiguli ukuthatha imphumulo, ukushintsha isikhundla komzimba).

Doppler ultrasound izitsha ikhanda nentamo: intengo inqubo

Doppler wenziwa okungatholakali ezibhedlela eziningi, ihhovisi noma amakhabethe kokuba ukuhlola sokusebenza. Ngaphambi kokuza inhlolovo, kumelwe oyi-ukubhalisa kwi Doppler ultrasound izitsha ikhanda nentamo. Intengo ye inqubo kuzoncika kukhethwa umtholampilo. Ngokwesilinganiso, kuba ruble 2300-3500. Kungcono ukuba aqhubeke isiqondiso ucwaningo. Kweminye imitholampilo, izitsha Doppler igazi isiphundu sabo ikhanda kwenziwa bengabantu ngabanye ndawonye. Kuleli kuncike intengo. UZDG izitsha Izindleko entanyeni (noma ikhanda) kuyinto kusukela ngo-1100 kuya ruble 1800.

Odokotela mayelana Doppler

Ngokusho odokotela, semithambo Doppler ultrasound indinganiso e izifo zobuchopho. Izinzuzo le ndlela kokuqukethwe awo ukulondeka Imininingwane okusezingeni eliphezulu. Ngaphezu kwalokho, azikho Izimo for ultrasonography. Petersburg (Petersburg) - umuzi lapho kukhona imitholampilo eminingi ifakwe-X-ray ukuhlola amakhabethe. izitsha Doppler igazi ekhanda nasentanyeni kungenziwa nezikhungo zezempilo, "Lahti" MEDEM, "Amandla", "nempilo ende", nokunye ..
