Chorion chirevo: chimiro uye unhu hwekuongorora uku

Chorion biopsy ndechidzidzo chinogona kuona kufanana uye kufanana nemararamiro epakutanga kwepamuviri. Nayo, sampuli yemakorioni inotorwa, iyo inogadzira iyo placenta.

Zvakakosha kuziva kuti hapana kushandiswa kwema fetus kunoitwa, naizvozvo chorionic biopsy inonzi yakachengeteka zvakakwana. Mushure mekufamba, dambudziko rekudzivirira kubvisa pamuviri kamwe chete 2%. Ichi chidzidzo chinopa migumisiro yakarurama, asi chinorwadza uye chinogona kukonzera malaise akaoma emukadzi ane pamuviri, saka inoitwa zvakakwana maererano nezviratidzo. Panguva imwecheteyo, nguva shoma shoma inopedzwa, uye zvigadziriro zvagadzirira mumazuva 3-4.

Pane 2 mikuru mikuru yekushungurudza uku:

• Vaginal chorionic villus biopsy - inoitwa pakati pevhiki neregumi nemana zvekubata. Pasi pekutungamirirwa kwe-ultrasound kuburikidza nemudzimai, chimbo chinokosha chinopindirwa muchibereko, chinowanikwa pakati pe endometrium uye chorion (iyo chibereko chemuti). Pakupiwa kwakapiwa villi pane chorion vanobviswa kana kunwa. Gare gare ivo vari pasi pekuongorora ma laboratory. Izvi zvinenge zvisinganzwisisiki.

• Chirwere chepamuviri chevilli chorion - chakaitwa pakati pevhiki 9 ne11 yehutumbi. Dzimwe nguva kushandiswa uku kunogona kushandiswa mumutsara wechipiri nechechitatu, nokuti inokubvumira kuti uwane mhinduro nokukurumidza, kunyanya mumamiriro ezvinhu apo pane zvishoma amniotic fluid, saka amniopuncture haigoni. Kuti agadzirise kushandiswa, murwere anorara pamusana wake. Chiremba anoshandisa iyo ultrasound machine kuti aone chinzvimbo che placenta, uterine masvingo, uyewo owana ramangwana rekuchengetedza nzvimbo yakachengeteka. Kuti utore zvinhu zvakakodzera nemumwe nheyo, kurohwa kwemuviri uye uterine masvingo kunoitwa, imwe - sampu yemasero inotorwa kuti ipfuurire mberi. Zvakakosha kuziva kuti nzvimbo yekuvhara iyo inoshandiswa nehutachiona hwemunharaunda ine mavara akanaka.

Chorionic biopsy inowanzotarisirwa kuvakadzi vane pamuviri, avo vane ngozi yakawanda yokuva nevana vane zvirwere zvepabonde, kunyange zvazvo mukadzi chero upi zvaanogona kuongorora iyi kana achida, panguva yekubata mwana.

Ndezvipi zvirwere zvinogona kuonekwa nemhando iyi yekuongorora? Ichi chikuru chinonzi Down's syndrome, Trisomy 13 uye 18 chromosome, Turner's syndrome, cystic fibrosis uye sickle cell anemia, pamwe neKlinefelter's syndrome. Mukuwedzera, chidimbu chechirion chinogona kuona nezvemazana zana echromosomal uye maitiro ezvakaipa.

Zvakakosha kuziva kukosha kwakakosha kweizvi kuongorora - inogona kushandiswa zvikuru kupfuura amniocentesis (sekutanga kwevhiki yegumi yekuzvitakura). Mukuwedzera, zvigumisiro zvinogona kuwanikwa zvakakurumidza-mune dzimwe nguva mumavhiki ekutanga mushure mekuongorora.

Ndinofanira kutaura kuti chorionic biopsy inogonawo kuratidza maitiro ekunyora, apo mamwe masero ane chimiro chechinyakare chromosomal, asi vamwe vakagadzira nezvimwe zvisiri izvo.

Mushure mokuongorora, kuisa mavara uye kutapudza marwadzo mumimba kunogona kuonekwa. Uyewo, amniotic fluid (mune zvishoma) inogona kusunungurwa kubva kumudzimai. Kana pane zviratidzo zvisingawanzooneke, unofanira kuonana nachiremba uyo ane pamuviri.
