Chorion chironga chenguva, kubva pane iyo placenta kana nzvimbo yomwana inoumbwa. Nemashoko akajeka, iyi ndeimwe yezvikamu zvinotevera mukuumbwa kweparcenta. Kubvira apo placenta inoumbwa zvishoma nezvishoma, kazhinji nevhiki yegumi nemasere, zvose zvinosvika kusvika pano zvinoshandiswa neshoko.
Yokutanga ultrasound pakuberekwa kunokurudzirwa kuti kuitwe mumavhiki 9-12 apo yakanyoreswa muLC, uye kazhinji kachengetwa vanopfuura 50% yevakadzi vane pamuviri vanoonekwa kuti vane marginal presentation ye chorion. Izvi zvinorevei?
Izvi zvinongoratidzira chete kuti kune chikwata chakakosha chechirion, kureva, mazai anogadzirwa , kurova chivharo chechiberekero, chakabatanidzwa kwete pasi (chinonyanya kufanana nemamiriro ezvinhu akanaka), asi chakaburukira kune rumwe rutivi rwechirwere uye chirwere chechibereki. Zvayakanga yapinda mukati memucheche, iyo ovum uye uterine epithelium yakaumba chorion.
Pane zvakawanda zvingasarudzwa zvekuratidzwa kwe chorion:
- chikamu chechikamu chechirion chimiro chekuratidzwa umo chorion inogona kushandura nzvimbo dzechirwere chechibereki uye chibereko chemuviri (chinonyanya kunakidza);
- mharidzo isina kukwana ye chorion - kusiyana kwekuratidzwa, iyo chikamu chechirion inoputira mukova weganda remudzimai, asi kwete kupfuura 2/3 yepakati;
- Zvose zvizere nemharidzo - chorion inodzivisa zvachose kuvhura kwenzara yemumuromo.
Majoka anowanzoonekwa munyaya yacho kana chorion iri pasi pechibereko.
Ndezvipi njodzi dzemhando dzakasiyana dzemharidzo?
Mhando ipi neipi yekutaurira inotyisa nokuti chorion inokura nemidziyo inoita placenta. Nechingoro chiduku chechirion, kubuda ropa kunogona kuitika, pangozi yekuvhiringidzika uye kutora pamuviri, pamwe nekushaya simba kwekuberekwa kwepanyama nekuda kwechiitiko chekubuda ropa uye kuberekwa kwekuberekwa mwana.
Muchikamu chemukati, dambudziko racho harisi, sezvo kune pfungwa yekufamba kwepa placenta, uye nemasvondo gumi nemasere mumatambudziko makumi mapfumbamwe nemakumi matatu emakwenzi iyo placenta inomuka pamadziro emuviri uye inotora nzvimbo yakakwana. Nehurukuro isina kukwana, chirevo chacho chinotarisirawo zvakare - ichi chisarudzo chinowanzoshandurwa kuva mumuromo wehurukuro kana kuti placenta inotora
Edge kuratidzwa kwechirion - kurapwa
Kurapa kwemashoko ekumucheto kazhinji kunowanzoonekwa nekucherechedza zvinorayirwa nachiremba, kureva: zororo rekurara pabonde, kunyanya kushanda mumuviri, kutadza kwepfungwa-mupfungwa uye kudya kunovaka muviri. Mharidzo isina kukwana inowanzoda kutarisa muchipatara uye kushandiswa kwemishonga. Kazhinji kazhinji vakadzi vanozvitakura vari munyaya iyi vanosarudza Dufaston maererano nemirairo.
