Kuchita kawirikawiri ka ultrasound kudzatithandiza kuona zolakwika zilizonse m'nthaŵi ndi kutenga zoyenera. Phunziroli limakhazikitsa malo a mwanayo, mlingo wa kukula kwake, makulidwe a placenta , kapangidwe kake.
Ndipo ngati mkazi auzidwa kuti pali dongosolo lopanda magazi la placenta, izi, ndithudi, zimayambitsa nkhawa ndi nkhawa. Ndipo izi sizosadabwitsa, chifukwa placenta, kuphatikizapo zakudya ndi kupuma, imakhala ngati chitetezo chotsutsana ndi matenda, operekera mahomoni oyenera komanso kutumiza katundu wa moyo wa mwanayo m'mimba.
Nchiyani chimayambitsa placenta yambiri?
Sikuti nthawi zonse kuperewera kwa placenta ndiko chifukwa chodetsa nkhaŵa. Nthawi zina, chikhalidwe choterocho chimaonedwa kuti ndichizoloŵezi. The placenta potsiriza amapangidwa ndi sabata 16. Ndipo zitatha izi, mpaka sabata la makumi atatu ndi zitatu, mawonekedwe a placenta sayenera kusintha. Ndipo muyenera kudandaula ngati ndi nthawi yomwe dokotala amapeza kusintha kwake.
Chifukwa chodandaula ndi mawonekedwe a placenta owonjezereka ochogenicity ndi kuzindikira za zosiyanasiyana inclusions mmenemo. Pachifukwa ichi, mawonekedwe osakanikirana a chiwalo amasonyeza kuphwanya kwachizoloŵezi chake.

Chifukwa cha kapangidwe kake ka placenta, magazi omwe amatha pakati pa mayi ndi mwana akhoza kusokonezeka, zomwe zidzakhudza zobwera. Chifukwa cha fetal hypoxia, mimba ingachepetse komanso imalepheretsa kukula kwa mwanayo.
Ngati kusintha kwa mapangidwe a placenta kumapezeka patatha masabata makumi atatu, izi zikutanthauza kuti zonse zimakhala zachilendo ndipo zimachitika momwemo. Nthawi zina ngakhale pa sabata 27, kusintha kumaonedwa ngati kozolowereka, ngati palibe zovuta pa kukula kwa mwana.
Pali zolemba pamaganizo a ultrasound "mapangidwe a placenta ndi kufalikira kwa MVP." MVP ndi malo osungirako zinthu, malo okhala mu placenta, kumene kuli kagayidwe kake pakati pa magazi a mayi ndi mwanayo. Kuwonjezeka kwa malowa kukugwirizana ndi kufunika koonjezera dera losinthana. Pali njira zingapo zowonjezera pulogalamu yopindulitsa, koma sizigwirizana ndi chitukuko cha kuchepa kwa feteleza. Ndichidziwitso ichi, palibe kufufuza kwina kofunikira.

Mlingo wa kusasitsa kwa placenta ndi mawonekedwe ake
Mphakayi amaonekera bwino pa ultrasound, kuyambira pa sabata la 12. Panthawi imeneyi, chidziwitso chake chimakhala chofanana ndi myometrium. Pakufika pa msinkhu wa 0, mtundu wofanana wa placenta umadziwika, ndiko kuti, mapangidwe ofanana omwe amapangidwa ndi mbale yosalala ya chorionic.
Pakalipire 1, mapangidwe a placenta amalephera kufanana kwake, zilembo za echogenic zikuwonekera mmenemo. Mapangidwe a placenta a 2 digiri amadziwika ndi maonekedwe a malo osokoneza bongo monga mawonekedwe. Ndipo kalasi yachitatu imadziwika ndi kuwonjezeka kwa calcification ya placenta.
