Kuti zvidzivirire mamiriro ezvinhu akadaro, mamiriro ose ezvirongwa zvinotarisirwa kudzivirira intrauterine pathologies yakagadzirwa, iyo yainzi inotanga kuberekwa, kana kuti kurapwa kwemazuva ose. Rudzi urwu rwekutsvakurudza runoitwa munharaunda yese yekuronga mhuri nekuongororwa kwemaininatal.
Chii chinonzi kurapwa kwemaininatal uye nei zvichidiwa?
Kana tikarangarira rudzi urwu rwekutsvakurudza mune zvakawanda uye taura nezveiyo chinangwa chikuru chekuongorora chirwere chepininatal, saka, chokwadi, uku ndiko kuonekwa kwokutanga kwema fetal pathologies, kunyange pamatambo ekuve mudumbu raamai. Iyi nharaunda yemishonga inonyanya kunetseka nekugadzirwa kwechromosomal, zvirwere zvekuzvarwa uye kuberekwa kusina kufanira mune ramangwana mwana.
Saka, nhasi vanachiremba vane mukana wekutarisa mukana wekuva nemwana ane chromosomal kusakanganiswa kakatova mukati me1 trimester yekudzivirira nehupamhi hwekutendeseka (inenge 90%). Kunyatsorarirwa kunobhadharwa kune zvirwere zvakadai seArt syndrome, Edwards syndrome, Patau syndrome (trisomy 21, 18 uye 13 chromosomes, zvichienderana).
Mukuwedzera, sechikamu chematambudziko ekuongorora chirwere chemainataline, ultrasound inogona kuongorora zvirwere zvakadai sechirwere chepfungwa, kukanganiswa kweuropi uye musana wemagunha, itsvo dze fetus, nezvimwewo.
Ndeipi nzira mbiri dzinoshandiswa pakuongorora chirwere chemaininatal?
Sezvo ataura kuti uku ndiko kuongororwa kwepininatal, uye kuti chii chinoitwa, tichakurukura mhando dzekutsvakurudza nayo.
Chokutanga pane zvose, zvakakosha kutaura pamusoro pekuongorora kuongorora, iyo inenge inenge mudzimai wese akanzwa panguva yekuita mwana. Yokutanga kudzidza kwakadaro kunoitwa panguva yevhiki gumi nembiri, uye inonzi "kuongorora kaviri". Pachigamba chekutanga, mukadzi anosangana ne ultrasound pane chimwe chinhu chakakosha, chinopesana zvikuru kubva pane icho chinowanzoshandiswa kune nhengo dzomukati. Kana ichiitwa, kutarisa kwakabhadharwa kune maitiro ezvimwe zviyero seye coccygeal-parietal size (CTE), kubwinya kwekoro nzvimbo.
Uyewo, kuverenga ukuru hwemucheche wakaberekwa musasa, kusanganisa huwandu hunobudirira hwekunamatira.
Chikamu chechipiri pakuitisa zvidzidzo zvekuongorora, zvinosanganisira kudzidza ropa remumai anouya. Kuti uite izvi, biomaterial inotorwa uye mhete uye inotumirwa ku laboratory, uko kuongororwa kunoitwa pahuwandu hwemhomoni inogadzirwa zvakananga neparcenta. Idzi ndidzo mapuroteni maviri anosangana nekuzvitakura: RAPP-A uye musununguko wakasununguka we chorionic gonadotropin (hCG). Ne chromosomal kusagadzikana, zvinyorwa zvepuroteni idzi muropa zvinoparadzanisa kubva pane zvinowanzoitika.
Nhoroondo yakagadziriswa semugumisiro wezvidzidzo zvakadaro yakapinda mune imwe purogiramu yekombiyuta inonyatsoratidzira njodzi yekuvandudza chromosomal pathology mune ramangwana mwana. Somugumisiro, sangano pacharo rinotarisa kana mukadzi ari pangozi kana kwete.
Zvose izvi zvinoshandiswa pasi pekutonga kwakasimba kwe ultrasound kuitira kuti arege kukuvadza mwana, uye chete nemumwe munhu anonyatsokwanisa. Izvozvo zvinokonzerwa nemasero emufetera anotumirwa kuine chidzidzo chekugadzira karyotype, mushure mokunge amai vanopiwa mhinduro chaiye - ingave mwana ane chromosomal isina kunaka kana kwete. Kudzidza kwakadaro, sekutonga, kunoitwa nemaitiro ekuongorora maitiro akanaka.
Nokudaro, mukadzi wese anofanira kuziva kuti nei kushanda kwakagadziriswa kuchiitwa munzvimbo inotarisirwa, uye kunzwisisa kukosha kwezvidzidzo izvi.
