I12-vhiki ye ultrasound ndiyo inonyanya kukosha panguva yekuzvitakura uye ndosaka iri imwe yekutanga maitiro ekuongorora akaitwa. itaChii chinoongororwa mu ultrasound yemwana ane mwedzi mitatu? Icho chidzidzo chekukosha kukuru kwekiriniki, uko mamiriro ese e "fetus" uye kukura kwayo kunoongororwa.
Iyo ultrasound yemwedzi mitatu yemwana inobvumira kuongorora intrauterine mamiriro emucheche kuitira kuti azive kana akaumbwa zvakanaka uye haatauri matambudziko makuru. Kuburikidza nenhevedzano yemaparamita, zvinhu zvakasiyana siyana zvine chekuita nekukura, kukura uye kuumbwa kwe "embryo" kunoongororwa.
Chii chinonzi ultrasound chemwedzi mitatu?
Kupfuura mamiriro ehutano, iyo Ultrasound yemwedzi mitatu Kunobaya mwoyo zvikuru sezvo uchikwanisa kunzwa mwoyo wemwana uchirova. Iyi i-high-resolution ultrasound inoongorora fetus mumativi ayo ese kuti ipe data yakakosha pane yayo. chimiro chose. Kunyangwe ichizivikanwa se12-vhiki yeultrasound, inogona kuitwa pakati pevhiki 11 ne14.
¿Chii chinoongororwa mumwedzi mitatu ye ultrasound? Chimwe chezvakazarurwa zvikuru kugona kududzira kana iri nhumbu imwe chete kana kuti pane inopfuura mwana mudumbu mumwechete. Hunhu hwe "fetus" hunoongororwawo kuburikidza nekurova kwemoyo. Kune rumwe rutivi, zviyero zvakasiyana-siyana zvinogadzirwa kuti zvigadzire ukuru hwemwana kuburikidza nekorona-caudal urefu. Kunyangwe ichiri danho rekutanga, mune iyi ultrasound zvinogoneka kumisikidza nhevedzano yezvipimo zvingaita kuti zvikwanise kuona kana chibereko chinogona kunge chiri panjodzi yeDown syndrome kana mamwe ma pathologies ane chekuita nekuchinja kwechromosomal.
Chimwe chinhu chakakosha chinoongororwa mu 3 mwedzi mwana ultrasound Kuiswa kwe "embryo", "placenta" uye kutarisa kuti hapana mavanga here, chinhu chinowanzoitika panguva ino yekuzvitakura. Nguva yekuzvitakura ye fetus inotariswa zvakare uye neizvi zvinogoneka kumisikidza zuva rinobvira rekuzvara. Zviyero zvinenge zvichiitwa zvinobvumira kukura kwemwana kuti kuongororwe kuona kana asina kukanganiswa mumuviri.
Vhiki 12 uye kuongorora katatu
Pamusoro pekuongorora generality yefetus, mu 3 mwedzi mwana ultrasound Chidzidzo chekuwedzera chinonzi nuchal translucency kana Triple Screening inoitwa zvakare. Muedzo uyu unoitwa pazuva rimwechete neultrasound uye rinotarisa bhonzo remumhino remwana uye nape folds. Idzi data dzinobva dzasanganiswa nedata rekuwedzera kugadzira mhedzisiro-yakavakirwa mhedzisiro yekuona njodzi dzemwana ane trisomy 21 kana Down syndrome uye trisomy 18, inozivikanwawo seEdward syndrome.
Triple Screening inoumbwa nezvinhu zvitatu zvinopatsanura. Kune rumwe rutivi, zera raamai rinoongororwa pamwe chete nemazinga emapuroteni maviri anogadzirwa ne placenta, yemahara beta-hCG uye PAPP-A. Iyi data inosanganiswa neiyo data inowanikwa mu nuchal translucency (kuongororwa kwemapeta emutsipa wemwana). Mhedzisiro inobereka indekisi yenjodzi kunyangwe zvichifanira kucherechedzwa kuti haisi bvunzo yekupedzisa. Nokuda kweizvi zvakakosha kuita amniocentesis.

Kazhinji, danho rekutanga pakuona izvi chromosomal abnormalities kuita nuchal translucency, iyo inoitwa panguva. 3 mwedzi mwana ultrasound. Muchiitiko chekuti njodzi yakakura kupfuura yaitarisirwa, chiremba anozokurudzira kuita mamwe marudzi ezvidzidzo kuitira kuti agadzirise maparamendi akajeka uye ave nemufananidzo mukuru. Imwe yesarudzo ndeyekuita ongororo yeDNA yemwana ari mudumbu muropa raamai uchishandisa sampuli yeropa kubva kuna amai. Imwe nzira ndeye amniocentesis kana chorionic biopsy. Chidzidzo ichi hachina simba uye ndosaka chichikurudzirwa mushure mekusununguka kana kuti amai vakwegura.
