Ultrasounds inogonawo kushandiswa panguva yekuongororwa maitiro ekuongorora asati aberekwa uye inogona kubatsira vanachiremba kuti vaone kuve nekukanganisa kuberekwa.
An Ultrasound Inoshanda Sei?
Ultrasound inoshandisa kuburikidza nekushandisa mazaya emhepo yakakwirira zvikuru kune nzeve yomunhu kuti inzwe kuti iite chifananidzo che fetus. Paunenge uchiita ultrasound, chiremba wako achachera giro rinokosha mudumbu rako uye achishandisa transducer, se-device-like-device, kutumira mazai ezwi mumimba yako. Mafungu aya haaiti pangozi kwauri kana mwana wako.
Mafungu anonzwika anofamba achipinda mumamniotic fluid uye anowedzera kunze kwezvivakwa zviri muchibereko. Mafungu aya anononoka kumhanya zvakasiyana-siyana zvichienderana nehuwandu hwezvivako zvavanotanga vasati vatsausa. Ikombiyuta inobva yatendeza mafungu aya anodzoka ari mufananidzo we fetus. Izvo zvakaoma kana denseer sarudzo ndeye, kujeka kuri kuratidzira pane chekuona.
Somuenzaniso, patinotarisa fetal ultrasound, zvivako zvebony zvakadai sedhehenya nemakumbo mapfupa zvinoratidza kuchena kwakachena.
Pasina nhengo dzakaoma, dzakadai sechiropa neitsvo, dzinoratidzika semuchena mutsvuku. Amniotic fluid inoratidzika seyema nokuti mafungu anonzwika anofamba achipfuura nepakati pemvura uye haadzokeri shure. Nokutarisa pamifananidzo iyi yakasviba nemachena, nyanzvi yezvehutano inokwanisa inogona kutarisa maitiro ako emwana.
Ko Ultrasound Inogona Kuongorora Chine Syndrome Here?
An ultrasound haigoni kuongorora Down syndrome.
Zvisinei, inogona kupa ruzivo pamusoro pemwana wako izvo zvingaita kuti chiremba wako awedzere kuedza kuongorora Down syndrome uye zvimwe zvromosomal zvisiri izvo. Zvimwe zviwanikwa zve ultrasound, dzimwe nguva zvinonzi soft markers , zvinowanikwa izvo, mukati uye pachavo, hazvingaiti kuti mwana ave nezvinetso asi zvingaratidza kuti chromosome iri pasi payo. Zvinyorwa zvakasimba zveArt syndrome zvinogona kusanganisira:
- Kuwedzerwa nuchal translucency: Nuchal translucency miyero yakawanda sei iyo yakakonzerwa nemvura yakasviba mushure memutsipa wako wekukura uri. Kana nzvimbo yacho yakanyanya kupfuura yakasvibirira, inogona kuva chiratidzo cheA Down syndrome.
- Shortened femur urefu: Mukadzi shoma, kana gumbo bone, inogona kuva imwe chiratidzo.
- Choroid plexus cysts: Izvi zvinowanikwa muuropi ye fetal.
- Intracardiac echogenic foci: Kuratidza mineralizations mumisungo yemwoyo, iyi ndiyo inowanzowanzoonekwa ye ultrasound.
- Echogenic bowel: Ichi chinyoronyoro chinoratidzira chinoratidzira chikwata sechiedza kupfuura chinofanirwa kuve.
- Single umbilical artery: Mhando dzakawanda dzemumbilical dzine mhino imwe uye mishonga mbiri.
- Dilated renal pelvis: Uyewo inowanzowana ultrasound ichiwana, iyo inoputika renal pelvis, kana kuti hydronephrosis, inoreva kuti nzvimbo yemapapiro neitsvo yakasiyana.
Kuwedzerwa Kuedzwa kweArt Syndrome
Kana chimwe chezvikwangwani izvi chikawanikwa pane yako ultrasound, unofanirwa kutaura nachiremba wako kana mutarisiri wehutano kuti uone dambudziko rako rokubata mwana ane chromosome isina kukodzera uye kuti ukurukure zvimwe zvekuedza kwepabonde iwe unogona kufunga.
Nzira chete yekuudza kana mwana wako ane chirwere chechiromosome chakakomba ndechokuti ave nechirwere chekuongorora chirwere chepakutanga sechirionic villus samples (CVS) test kana amniocentesis. Iyi miedzo inofadza asi inogona kukubatsira kuona utano hwemwana wako huchauya.
Kunyangwe kana imwe yezviratidzo ichi ichionekwa panguva yako ye ultrasound, zvakakosha kuyeuka kuti vana vakawanda vane imwe yezvivaraidza vanova vana vane utano hwakakwana vasina nhengo dzechromosome dzisina kunaka.
Ultrasound inongova kuongorora kuongorora uye haigoni kuongorora Down syndrome kana zvimwe zvinokonzera chromosome.
