Inqubo yokwakhiwa kwe- placenta ngesikhathi sokukhulelwa igcwaliswa ngesonto 16. Kusukela kule nkathi, ngesikhathi sokuhlolwa kwe-ultrasound, izinga lokuvuthwa kwe-placenta liyonqunywa. Ukunquma izinga lokuvuthwa kwe-placenta kuyimfuneko ebalulekile yokuxilonga yokukwahlulela ukuthi isebenza kangakanani: ukulethwa kwe-oksijeni nezakhi kumntfwana.
Indlela yokunquma ukuvuthwa kwe-placenta 1, 2, 3?
Ingqikithi kunezinhlobo ezine zokuvuthwa kwe-placenta kusuka ku-0 kuya ku-3. Cabanga ukuthi yiziphi izimpawu ze-ultrasound ezihambelana naleso ngasinye salezi zigaba:
- izinga lokuvuthwa kwe-placenta 0 litholakala ngaphambi kweviki lama-30 lokukhulelwa. Phakathi nalesi sikhathi, isakhiwo se-placenta sihambisana;
- izinga lokuvuthwa kwe-placenta 1 linqunywa kusukela emavikini angu-28 kuya kwangu-34 wokubeletha. Lelizinga lokuvuthwa libhekene nokuba khona kwenani elincanyana le-inclusions ye-echogenic, kanye nokubonakala kokugcoba kwe-plate chorionic;
- izinga lokuvuthwa kwe-placenta 2 linqunywa esikhathini samasonto angama-35-39. Ku-ultrasound ye-placenta enjalo, ukuchithwa kwe-plate chorionic kwanda futhi inani le-inclusions hyperechoic landa;
- izinga lokuvuthwa kwe-placenta 3 lingavame ukuvela ngesonto lama-37 lokukhulelwa. I-degree yesithathu yokuvuthwa kwe-placenta ibonakala ngesakhiwo se-lobular futhi isikhombisa ukuhlukumeza kwendwangu ye-chorionic.
3 ukuvuthwa kwe-placenta ngaphambi kwamasonto angu-37 noma ukuvuthwa kokuqala kwe-placenta
Ukuvuthwa kokuqala kwe-placenta kubonisa ukungakwazi ukusebenza kwe-placenta ekuhlinzekeni i-fetus nge-oxygen nezakhi, okuholela ekubambezelweni kokuthuthukiswa kwe-intrauterine. Izizathu zalesi simo zingaba: i-extragenital pathology, preeclampsia, ukuphuma kwegazi esikhathini sokuqala sokukhulelwa, njll. Ezimweni ezinjalo, owesifazane ngokuqinisekile uzobe enqunywe ukwelashwa okuhloswe ekuthuthukiseni ukujikeleza kwegazi ku-placenta.
