Funda oko i-CRL enokukuxelela ngayo ngomntwana wakho
Ubude beConcer rump (CRL) ngumlinganiselo we-ultrasound osetyenziswa ngexesha lokukhulelwa. Ingane ibalwa, ngamasentimitha, ukusuka kwintloko yentloko (isithsaba) ukuya ngasezantsi emacaleni abo (rump). Izitho kunye ne-yolk sac ayifakiwe kwisilinganiselo. I-CRL inokulinganiswa ukusuka ekuqaleni kweeveki ezintandathu okanye ezisixhenxe zokukhulelwa de iiveki ezili-14. I-CRL inokuba luncedo ekubaleni iminyaka yobudala .
Ngalesi sidima sobudala, oogqirha banokuqikelela ukuba ungayifumana njani umhla wokubakho. Ngaphambili kwangaphambili i-ultrasound eyenziwa, ichanekile ngokugqithiseleyo iminyaka yobudala bomntwana iya kuba.
Emva kokuba umntwana sele ephuhlise iiveki ezi-14 ezedlulileyo , iinqununu zentloko, ububanzi biparietal , kunye nobude bentombazana zisetyenziselwa ukuchonga indlela umntwana eqhubeka ngayo. Ubungakanani bentambo yomtya bufana ne-CRL ngexesha lokukhulelwa.
Into eyenziwa yi-CRL malunga neMpilo yabantwana
Emva kokuba i-CRL yesisu ikhuphe i-7 mm, intliziyo ifanele ifunyanwe yi-ultrasound yangaphandle-i-ultrasound eyenziwa ngebhinqa kwaye ingekho ngaphezulu kwesisu esisisigxina se-ultrasound. Ukuba akukho nto intliziyo okanye umsebenzi wenhliziyo ofunyenweyo, ngoko ukukhulelwa kungahle kwenzeke ukukhulelwa komzimba. Ukulahleka komzimba, okanye ukuthutha, kuvela ngaphandle kwempawu eziqhelekileyo zokukhulelwa komzimba. I- placenta ingaqhubeka nokubonelela i-hormone, ekwazi ukugubungela iimpawu zangaphandle zokuphuphuma kwesisu.
Abafazi abanentsingiselo yesigxobo se-sac (MSD) abangaphantsi kwama-5 mm ngaphezu kwe-CRL banokuthi bafumane ukukhulelwa kwe -first-trimester-nokuba umntwana unesilinganiselo senhliziyo evamile. Ukugqithiswa kwenyanga yesithsaba esancinci kunokukwazi ukuxilonga iziphulo ezinjenge-trisomy 18 (i-Edwards syndrome) kunye nezinye izifo ezinxulumene nokuthintela ukukhula.
