Funda ukuthi i-CRL ingakutshela ngani nge-fetus yakho
Ubude bekhanda (CRL) ubude be-ultrasound esetshenziswa ngesikhathi sokukhulelwa. Ingane ilinganiswa, ngamasentimitha, kusukela phezulu kwekhanda labo (umqhele) kuze kube phansi kwamathambo abo (i-rump). Izitho kanye ne-yolk sac ayihlanganisiwe ekulinganisweni. I-CRL ingalinganiswa kusukela ekuqaleni kwamasonto ayisithupha noma ayisikhombisa ekukhulelwa kuze kufike amasonto angu-14. I-CRL ingaba usizo ekubaleni iminyaka yobudala .
Ngalesi sikhathi sokuthoma, odokotela bangalinganisa usuku lwakho olungenzeka ngalo. Ekuqaleni i-ultrasound yokuqala iyenziwa, isikhathi esinembile kakhulu sokubeletha kwengane kuyoba.
Uma isisu selithuthukile amaviki angu-14 edlule, ukuzungeza ikhanda, ububanzi be-biparietal , nesilinganiso se- femur isetshenziselwa ukunquma ukuthi ingane iqhubeka kanjani. Ubude bezintambo zomzimba ngokuvamile bufana ne-CRL phakathi nokukhulelwa.
I-CRL Ingasitshela Ngayo Impilo Yengane
Uma i-CRL yesitho sowedlula i-7 mm, ukushaya kwenhliziyo kumele kutholakale nge-ultrasound yangaphakathi-i-ultrasound eyenziwa nge-vagin futhi hhayi phezulu kwesisu njengesimiso esivamile. Uma kungekho ukushaya kwenhliziyo noma umsebenzi wezinhliziyo, kutholakala ukuthi ukukhulelwa kuyiphutha lokulahlekelwa kwesisu. Ukuphutha kwesisu okungahoxwanga, noma okuthulile, kwenzeka ngokujwayelekile ngaphandle kwempawu ezijwayelekile zokukhulelwa kwesisu. I- placenta ingase iqhubeke nokunikeza ama-hormone, okungafihla izibonakaliso zangaphandle zokukhulelwa kwesisu.
Abesifazane abanesisindo samagciwane esiphansi (MSD) abangaphansi kuka-5 mm ngaphezulu kune-CRL cishe banokuhlukumeza isisu sokuqala-ngisho noma umntwana enesilinganiso senhliziyo evamile. Ukunciphisa ubude be-crown rump kungabuye kuhlolwe ukukhubazeka kwe-chromosomal efana ne-trisomy 18 (i-Edwards syndrome) nezinye izifo ezihlobene nomkhawulo wokukhula.
