Ukuthuthukiswa okujwayelekile kokukhulelwa kanye nenkambo yokuzalwa ngokwakho kuncike ikakhulukazi esimweni se-placenta. Nguye onomthwalo wokondla ingane futhi uyinikeze nge-oxygen. Ngakho-ke, odokotela baqondisa lo mzimba ukukhulelwa konke.
Ukuziphatha okuqhubekayo kwe-ultrasound kuzovumela ukuthola noma yikuphi ukwehluka ngesikhathi futhi uthathe izinyathelo ezifanele. Ucwaningo lubeka indawo yendawo yengane, izinga lokuvuthwa kwalo, ubukhulu be-placenta , isakhiwo.
Futhi uma owesifazane etshelwa ukuthi kukhona isakhiwo esiyingqayizivele se-placenta, lokhu, ngokuqinisekile, kubangela ukukhathazeka nokukhathazeka. Futhi lokhu akumangalisi, ngoba i-placenta, ngaphezu kokudla okunomsoco nokuphefumula, isebenza njengomvikeli wokulwa nezifo, umhlinzeki wamahomoni adingekayo kanye nokuthuthwa kwemikhiqizo yobomi bomntwana esibelethweni.
Yini ebangela i-placenta engavamile?
Akuzona njalo ukuphazamiseka kwe-placenta kuyimbangela yokukhathazeka. Kwezinye izimo, isimo esinjalo sibhekwa njengesijwayelekile. I-placenta ekugcineni yenziwa ngesonto 16. Futhi emva kwalokho, kuze kube yiviki le-30, isakhiwo se-placenta akufanele sishintshe. Futhi udinga ukukhathazeka uma kulesi sikhathi lapho udokotela ethola izinguquko kwisakhiwo saso.
Isizathu sokukhathazeka yisakhiwo se-placenta sokwanda kwe-echogenicity nokutholakala kweziqu ezihlukahlukene kuwo. Kulesi simo, isakhiwo esiyingqayizivele sesigungu sibonisa ukwephula ukusebenza kwayo okujwayelekile.
Isizathu salezi zinkinga singase sibe nezifo ezikhona emzimbeni wesifazane. Ukuthinta kabi ukuthuthukiswa kwe-placenta, ukubhema, utshwala, i-anemia nezinye izici. Ngenxa ye-heterogeneity ye-placenta, ukugeleza kwegazi phakathi komama nengane kungaphazanyiswa, okuzophazamisa okwedlule. Ngenxa ye- fetus hypoxia, ukukhulelwa kunganciphisa ngisho nokuyeka ngokuphelele ukuthuthukiswa kwe-fetus.
Uma izinguquko esakhiweni se-placenta zitholakala ngemva kwamasonto angu-30, lokhu kusho ukuthi konke kuvamile futhi kuya njengokulindelwe. Ngesinye isikhathi ngisho nangesonto 27, izinguquko zibhekwa njengejwayelekile, uma kungekho okungajwayelekile ekuthuthukiseni ingane.
Kukhona irekhodi kwiziphetho ze-ultrasound "isakhiwo se-placenta ngokukhuliswa kwe-MVP." I-MVP yizikhala ze-intervillar, indawo e-placenta, lapho kune-metabolism ephakathi kwegazi lomama nengane. Ukwandiswa kwezi zindawo kuhlotshaniswa nesidingo sokwandisa indawo yokushintshaniswa. Kunezinketho eziningana zokwandisa isikhungo senzalo, kodwa azihlobene nokuthuthukiswa kokungakwazi ukuhamba kahle kwe-fetoplacental. Ngalolu cwaningo, akukho ucwaningo olwengeziwe oludingekayo.
Isakhiwo esiyingqayizivele se-placenta nge-calcification esinye isakhiwo se-placental. Kulesi simo, ingozi akuyona ukubalwa okunjalo, kodwa ukuba khona kwabo. Bavimbela i-placenta ukwenza imisebenzi yayo ngokugcwele.
Isakhiwo se-placenta esinokubalwa okuncane ekukhulelweni kwesikhathi sekwephuzile akusona isizathu sokukhathazeka. Lokhu kungenzeka ukuthi kukhombise ukuguga kwe-placenta, okuyinto emva kwamaviki angu-37 evamile. Ezimweni ezingu-50% emva kwamasonto angu-33 ku-placenta, kutholakala ama-calcicates.
Izinga lokuvuthwa kwe-placenta nesakhiwo salo
I-placenta ibonakala ngokucacile ku-ultrasound, kusukela ngeviki le-12. Phakathi nalesi sikhathi, i-echogenicity yayo ifana ne-echogenicity ye-myometrium. Ngesilinganiso sokuvuthwa kwe-0, isakhiwo esihambisanayo se-placenta siyaqaphela, okungukuthi, isakhiwo esihambisana nendawo esakhiwe yi-plate chorionic esebushelelezi.
Kakade ngezinga elingu-1, isakhiwo se-placenta silahlekelwa ukufaniswa kwayo, iziqu zokuthi zi-echogenic zivele kuwo. Isakhiwo se-placenta yesilinganiso sesibili sibhalwe ukubonakala kwezingosi ezixubile ngendlela yama-commas. Futhi ibanga lesi-3 libhekene nokukhula kokubalwa kwe-placenta.
