Monochorionic ntxaib feem ntau muaj ob lub hnab amniotic (hu ua Monochorionic-Diamniotic "MoDi"), tab sis qee zaum, nyob rau hauv rooj plaub ntawm cov menyuam ntxaib monoamniotic (Monochorionic-Monoamniotic "MoMo"), lawv kuj muab tib lub hnab amniotic. Cov menyuam ntxaib Monoamniotic tshwm sim thaum kev sib cais tshwm sim tom qab cuaj hnub tom qab fertilization.
MoDi ntxaib ntau npaum li cas?
Monochorionic-diamniotic ntxaib (MoDi) tshwm sim hauv 0.3% ntawm tag nrho cov cev xeeb tub. Twin-to-twin transfusion syndrome (TTS) uas tshwm sim hauv 20% ntawm MoDi cev xeeb tub yog txuam nrog kev mob perinatal siab thiab kev tuag. MoDi ntxaib uas tsis muaj TTS ntau zaus (80%) tab sis tau tshaj tawm tsis txaus.
Puas Monochorionic Diamniotic ntxaib zoo ib yam?
Monochorionic, diamniotic (MCDA) ntxaib yog cov khoom ntawm ib qho fertilized ovum (qe), ua rau hauv cov noob caj noob ces zoo tib yam. MCDA cov menyuam ntxaib sib koom ib qho placenta (cov ntshav muab) tab sis muaj cov hnab amniotic cais.
Puas yog MoDi ntxaib muaj kev pheej hmoo siab?
Thaum txhua tus menyuam ntxaib muaj kev pheej hmoo ntau duapiv rau "singleton" cev xeeb tub (ib tus menyuam), cov menyuam ntxaib monochorionic ntsib kev pheej hmoo ntau dua vim yog cov placenta sib koom. Qee qhov teeb meem tuaj yeem ua rau mob hnyav, ua rau muaj kev hem thawj ntawm ib lossis ob tus menyuam mos lub neej.
Dab tsi ua rau MoDi tus menyuam ntxaib?
Thaum tus menyuam ntxaib monozygotic, lub blastocyst ces sib cais thiab tsim ua ob lub embryos. Yooj yim muab, cov menyuam ntxaib monozygotic tshwm sim thaum aib qe fertilized faib ua ob. Los ntawm ntawd, ob lub embryos loj hlob mus rau ob tug me nyuam.
