Munguva yekubata pamuviri, mwana ari mudumbu raamai anonzwa kudiwa kwakasimba uye nguva dzose kwehupenyu hwemhepo nguva dzose uye zvinhu zvinodiwa pakugadzirwa kwayo. Kuti apiwe nezvose zvinodiwa uye zvakakwana, zvakasikwa zvakagadzira nhengo dzakasiyana-siyana dzakadai sechirion uye placenta pakuberekwa .
Iyo mutsara ndiyo embryonic yekunze yemumbrane inopoteredza embryo uye inoumbwa panguva yekutanga kwepamuviri. Iine nhamba huru yemidziyo yakakoswa inopinda mumasvingo emuviri.
Sezvo nguva yekuita muviri inowedzera, ukuru hwezvakadaro zvinokurawo zvishoma nezvishoma, zvinoita kuti vashandure uye vashandure kuva villian chaiyo yezvinyorwa. Iyo yekupedzisira inopa metabolism yakakwana pakati peamai uye fetus. Uhu hwakawanda hwemavhiri pamasvondo gumi nemaviri hwakawanda kwazvo zvokuti hunochinja huchiita sepentecenta. Ndiyo mutumbi wenguva pfupi uchange uine hutano hwehutano hwemwana panguva yekugadzirisa.
Panguva yekuzvitakura, kusungirirwa kwakarurama kwevhiriyumu yakaipa kunobatanidzwa basa rinokosha, iro rinotarirwa muchikamu chekutanga che ultrasound. Sezvo mutemo, pane zvitatu zvechimiro chekugara munzvimbo, iyo:
- pane rusvingo rwushure rwechibereko;
- mberi;
- low attachment.
Zvose hazvina kufungidzirwa pathologies uye hazvifaniri kukonzera kutya mune ramangwana amai.
Chimiro chechirion, chinoratidzika pane chekuona chezvinhu zvinonzi ultrasound, zvinomiririrwa nemhete mutsvuku, iyo inotsanangurwa uye inowanikwa kumucheto wekunze kweiyo fetal egg. Kudzidza kwakanyatsoruramisa kunopa mukana wekufunga kunyange yevilli villi. Uhu hwenheyo pamatangi ekutanga ekudzivirira hunoyera mumamilimita uye, sekutonga, zvinenge zvakaenzana nenguva yekuzvara mumavhiki.
Ndezvipi zvinoshandiswa nechariyori panguva yekuzvitakura?
Muviri uyu unotanga basa rawo pamatambo ekutanga ekuvandudzika kwemukati uye inosanganisira zvinotevera:
- kupa kupa mari mukati meamai nemwana;
- kudzivirira kwe fetus kubva kune hutachiona uye mavhairusi;
- trophic and excretory basa.
Kazhinji, vanaamai vaduku, vawana migumisiro yekutsvakurudza nemichina ye ultrasound, vanotarisana nenhamba yakawanda yekusinganzwisisiki uye kutya kunobatanidza nechikamu ichi chenguva pfupi. Funga nezvezvakawanda kwazvo kwavari:
- Chorion is annular - ichi chimiro chemazuva ose, icho chinoramba chiine mavhiki masere kana mapfumbamwe ekuberekwa. Mushure menguva iyi, chorion inoshandurwa kuva yakasvibiswa uye yakasungirirwa, iyo inofanirwa kuti iwedzere kushanduka kuve placenta uye kupiwa kwakakwana kwomwana nezvinhu zvose zvinodiwa.
- Irodhionic cyst kazhinji inokonzerwa nekuputira kwakaitika panguva yekudzivirira kana kuti isati yasvika. Nzvimbo iyo cyst iripo haisi iyo inopa neropa uye inoparadzaniswa kubva kune placenta. Kazhinji zviitiko zvakadaro zviduku uye hazvina kuroorwa, uye hazvirevi kukanganisa nguva yekuzvitakura.
- Hyperplasia ye chorion inzira yekuwedzera nhamba ye capillaries yayo nekuwedzera kwayo. Izvi zvichapa mukana wekuponesa hupenyu hwemwana,
kana kuberekwa hakuitike panguva. - Chimiro chakasiyana-siyana chechirion kana kukura kwayo kusina kukwana kunogona kutungamirira pakuparara kwepabonde. Iyi nzira ichiri kudanwa hypoplasia. Vorsinki chorion chaizvoizvo inoparadzana kubva pamadziro emuviri uye fetal egg yai exfoliates.
- Kazhinji kune dambudziko nekutsanangurwa kwezvarinoreva: " vascular chorionic villus ". Panzvimbo yekugadzirwa kwechirongwa ichi, kusabatwa kunogona kuitika, uye mitsipa yeropa haigoni kuiswa.
Izvo zvakagadziriswa zvakagadziriswa zve ultrasound kune amai vamangwana "shanduko isina kuchinjwa yezvakagadzirwa", kana yakabudiswa musati mavhiki gumi nemaviri. Kana zvisina kudaro, izvi zvinogona kureva kuti pamuviri haubatanidzi kurongeka.
