I-Chorion yilungu lesigxina, apho i-placenta okanye indawo yomntwana yenziwe khona. Ngendlela elula, le ngenye yezigaba ezilandelelanayo ekuvelweni kwepentecenta. Ekubeni i-placenta yenziwe ngokuthe ngcembe, ngokuqhelekileyo ngeveki ye-18, yonke imisebenzi kuze kube ngolu hlobo iqhutyelwa yintetho.
Kunokucetyiswa ukuba i-ultrasound yokuqala ekukhulelweni kwimizuzu engama-9 ukuya ku-12 xa ibhaliswe kwi-LC, kwaye ngokuphindaphindiweyo egcinwe ngaphaya kwe-50% yabasetyhini abakhulelweyo bayabonwa ukuba banesingeniso esisezantsi. Kuthetha ukuthini oku?
Ukuxilongwa kubonisa ukuba kukho i-attachment ephantsi yeqhekeza, oko kukuthi, iqanda elichumayo , elibetha umtya wesibeleko, eliqhotyoshelweyo lingagqibekanga (imeko ebonakalayo yimizimba kunye nefanelekileyo), kodwa wehla waya kwicala lomlomo wesibeleko kunye nomngcingo wesibeleko. Emva kokungena kwi-membrane ye-mucous, i-ovum kunye ne-uterine epithelium yakha i-chorion.
Kukho iindlela ezininzi zokunikezelwa kweqhosha:
- Ukuqhotyoshelana kwendawo yokuqhafaza yindlela yokubonisa apho i-chorion inokuthi iguqulwe kwimimandla yomsele wesibeleko kunye nomlomo wesibeleko.
- Isingeniso esingaphelelanga sekhetho - ukuhluka kweentetho, apho inxalenye yesikhotho iguqula umnyango womngcingo wesibeleko, kodwa ingabi ngaphezu kwama-2/3 ububanzi bawo;
- Ukuzaliswa kwenkcazelo ye-chorion - i-chorion igqithise ngokupheleleyo ukuvulwa komsele womlomo wesibeleko.
I-placentation eqhelekileyo iboniswa kwimeko xa i-chorion ingezantsi kwe-uterus.
Ziziphi iingozi zeentlobo ezahlukeneyo zokubonisa?
Naluphina uhlobo lwenkcazo luyingozi kuba i-chorion ihluma ngeempahla ezenza i-placenta. Ngeqhosha elincinci le-chorion, ukuphuma kwegazi kungenzeka, ingozi yokuphazanyiswa nokungakhulelwa, kunye nokungakwazi ukuzalwa ngokwasemzimbeni ngenxa yomngcipheko wokufa kwegazi kunye nokufa komntwana kokubeleka.
Kwintetho engezantsi, umngcipheko awuncinci, kuba kukho imvelaphi yokufuduka kwepentecenta, kwaye ngeeveki ezingama-18 kwi-90% yamatyala aphakamileyo aphakama eludongeni lwesisu kwaye ahlala kwindawo eqhelekileyo. Ngentetho engaphelelanga, ukugxekwa kwakhona kunokuba nethemba - eli khetho lidla ngokuphindaphindiweyo libe yintetho engezantsi okanye i-placenta ithatha
Inkcazo ye-Edge ye-chorion - unyango
Ukunyangwa kwenkcazo esezantsi kufana nokuhlawula iingcebiso zogqirha, oko kukuthi: ukuphumla ngokwesondo, ukunyanzeliswa komzimba, ukunyusa kwengqondo kunye nokutya okunengqiqo. Isalathiso esingapheliyo sisoloko sifuna ukubonwa esibhedlele kunye nokusetyenziswa kwamachiza. Uninzi lwabafazi abasetyhini abakhulelweyo kule ngxaki bamisela iDufaston ngokwemiyalelo.
