Iyo yakagadziriswa kukura kwekuzvimba uye nguva yekuberekwa kwayo pachayo inowirirana nehutano hweparcenta. Ndiye uyo ane basa rokudyisa mwana uye kugovera naro nehogijini. Nokudaro, vanachiremba vanotarisira muviri uyu kubata pamuviri.
Nguva dzose mufambiro we ultrasound unobvumira kuona chero kusvibiswa kwepanguva uye kutora matanho akakodzera. Chidzidzo chacho chinogadza nzvimbo yenzvimbo yemwana, chiyero chekukura kwayo, kuwanda kwepentecenta , chimiro.
Uye kana mukadzi akaudzwa kuti kune chimiro chakasiyana chepentecenta, izvi, zvechokwadi, zvinokonzera kuzvidya mwoyo uye kuzvidya mwoyo. Uye izvi hazvishamisi, nokuti iyo placenta, kuwedzera pakudya uye kupemha, inoshumira semudziviriri anorwisana nehutachiona, mutengi wehomoni dzinodiwa uye kutakura kwezvigadzirwa zvehupenyu hwemucheche mudumbu.
Chii chinokonzera heterogeneous placenta?
Kwete nguva dzose hutano hwepascenta inokonzera kunetseka. Mune zvimwe zviitiko, nyika yakadaro inonzi inofanirwa. Ipaenteka inozopedzisira yakagadzirwa nevhiki 16. Uye shure kweizvozvo, kusvikira vhiki ye30, chimiro chepa placenta hachifaniri kuchinja. Uye iwe unofanirwa kuzvidya mwoyo kana iri panguva iyi apo chiremba anoona kuchinja kwarongwa hwayo.
Chinokonzera kunetseka ndechekugadzirwa kwepentcenta yekuwedzera echogenicity uye kuonekwa kwezvinhu zvakasiyana-siyana zvinowanikwa mairi. Muchiitiko ichi, chimiro chakasiyana-siyana chechirongwa chinoratidza kuputsa kwaro kushanda.
Chikonzero chezvinetso izvi zvinogona kuva zvirwere zviripo mumuviri wemukadzi. Hazvina kukanganisa kukura kwepascenta, kusvuta, doro, anemia uye zvimwe zvimwe zvinhu. Somugumisiro weheterogeneity ye placenta, ropa rinoyerera pakati peamai nemwana rinogona kuvhiringidzika, izvo zvichabata zvekupedzisira. Pamusana pe fetal hypoxia, pamuviri unogona kuderera uye unomisa zvachose kukura kwe fetus.
Kana kuchinja kwechimiro chepa placenta kunowanikwa mushure memavhiki makumi matatu, izvi zvinoreva kuti zvinhu zvose zvakajairika uye zvinoenda sezvinotarisirwa. Dzimwe nguva kunyange pavhiki 27, kuchinja kunofungidzirwa kwakasununguka, kana pasina kuipa kwekukura kwekurera.
Pano pane nhoroondo mu "ultrasound" mhedziso "chimiro chepa placenta pamwe nekuwedzera kweMVP." MVP inzvimbo dzakaputika, nzvimbo munzvimbo yepentecenta, uko kune metabolism pakati peropa raamai nemwana. Kuwedzerwa kwezvivako izvi kunosanganiswa nekudiwa kwekuwedzera nzvimbo yekuchinjana. Kune dzimwe nzira dzakasiyana-siyana dzekuwedzera purogiramu yeprofitori, asi haisi yakabatana nekuvandudzwa kwe fetoplacental kusakwanira. Nezvo kuongororwa, hapana tsvakurudzo inowanikwa inodiwa.
Izvo zvakagadzirwa zvakasimba zve placenta ne calcification ndeimwe zvakasiyana-siyana zvechimiro chemukati. Munyaya iyi, njodzi haisi iyo calcification saizvozvi, asi kuvapo kwavo. Vanodzivirira iyo placenta kubva pakuita mabasa ayo kusvika zvakakwana.
Chimiro chepa placenta nediki maverengi ekudzivirira kwekupedzisira haisi chikonzero chokufunganya. Izvi zvinonyanya kuratidza kukwegura kwepa placenta, iyo mushure mavhiki makumi matatu nemasere. Muchikamu makumi mashanu kubva mazana makumi matatu nemaviri mushure memavhiki makumi matatu nemakumi maviri nemasere mu-placenta, calcicates inowanikwa.
Chiyero chekutsvaga kwepascenta uye chimiro chayo
Iyo placenta inonyatsooneka pane ultrasound, kutanga pavhiki yegumi nembiri. Munguva iyi, kuburitswa kwaro kwakafanana neychogenicity ye myometrium. Pakukura kwekukura 0, chimiro chinogadziriswa che placenta chinocherechedza, kureva, chimiro chinogadziriswa chakakonzerwa neketari yakashata yakadii.
Sekuda kusvika 1, chimiro cheparcenta chinorasikirwa nekufanana kwayo, echogenic inclusions inowanikwa mairi. Chimiro che placenta chechipiri chechipiri chinoratidzwa nekuonekwa kwemasayiti echopositive nenzira yema commas. Uye gorosi 3 inozivikanwa nekuwedzera kuverenga kwepentecenta.
