I-chorion iyilungu lesigceme, lapho i-placenta noma indawo yengane yakheka khona. Ngamagama alula, lokhu kungenye yezinyathelo ezilandelanayo ekwakheni i-placenta. Njengoba i-placenta ikhiwa kancane kancane, ngokuvamile ngeviki lesishiyagalombili, yonke imisebenzi kuze kube manje iyenziwa yi-chorion.
I-ultrasound yokuqala ekukhutheni kunconywa ukuba kwenziwe emavikini angu-9-12 uma ibhaliswe ku-LC, futhi ngokuvamile esitokisini abesifazane abangaphezu kuka-50% abakhulelwe bayatholakala ukuthi banezethulo ezilinganiselwe ze-chorion. Kusho ukuthini lokhu?
Lokhu kuhlolisiswa kubonisa kuphela ukuthi kukhona okunamathiselwe okuphansi kwe-chorion, okungukuthi, iqanda elivundisiwe , elishaya isisu lesibeletho, elihlanganiswe hhayi phansi (isimo esiphezulu kakhulu nesimo esihle), kodwa sasiwela eceleni komlomo wesibeletho nomsele wesibeletho. Ngemuva kokungena embranini yomsindo, i-ovum ne-uterine epithelium yakha i-chorion.
Kunezinketho eziningi zokwethulwa kwe-chorion:
- Okunamathiselwe okuncane kwesigubhu sezinhlayiyamu uhlobo lwenkulumo lapho i-chorion ikwazi ukuguqula khona izifunda zomsele womlomo wesibeletho nomlomo wesibeletho (okuhlukile okuhle);
- isethulo esingaphelele se-chorion - ukuhlukahluka kwesethulo, okuyingxenye ye-chorion ewela umnyango womngcwabo womlomo wesibeletho, kodwa hhayi ngaphezu kuka-2/3 ububanzi bawo;
- ukugcwalisa ukunikezwa kwe-chorion - i-chorion igwema ngokuphelele ukuvulwa komsele womlomo wesibeletho.
I-placentation evamile iyabonakala lapho kwenzeka ukuthi i-chorion ingaphansi kwesisu.
Ziyini izingozi zezinhlobo ezehlukene zokwethulwa?
Noma yiluphi uhlobo lwesethulo luyingozi ngoba i-chorion ihluma nemishini eyenza i-placenta. Nge-attachment encane ye-chorion, kungase kuvele ukuphuma kwegazi, ingozi yokuphazanyiswa kanye nokukhulelwa, kanye nokuntuleka kokuzalwa komzimba ngenxa yengozi yokuphuma kwegazi kanye nokufa komntwana ongakazalwa.
Esikhathini sesethulo esincane, ingozi iyinto encane, ngoba kukhona umqondo wokufuduka kwe-placenta, futhi ngamasonto angu-18 ngamacala angu-90% i-placenta iphakama odongeni lwesisu futhi isendaweni evamile. Ngesethulo esingaphelele, ukubikezela kubuye kube nethemba - le ndlela ngokuvamile iphenduka isethulo esincane noma i-placenta ithatha
I-edge isethulo se-chorion - ukwelashwa
Ukunakekelwa kwesethulo sangasese kuvame ukubheka izincomo zesidakamizwa, okuwukuthi: ukuphumula ngokocansi, ukuzikhandla okungokwenyama, imithwalo engaphansi kwengqondo-ngokomzwelo nokudla okunengqondo. Isethulo esingaphelele ngokuvamile sidinga ukubonwa esibhedlela kanye nokusetshenziswa kwemithi. Abesifazane abaningi abakhulelwe kule nkinga baqoka uDufaston ngokwemiyalo.
