Nuchal translucency: chii icho, chii chaicho uye kuti zvinoitwa sei

Zvemukati

• Chii chinonzi bvunzo
• Maitirwo azvo uye mareferensi kukosha
• Nguva yekuita nuchal translucency

Iyo nuchal translucency bvunzo, inoitwa panguva yeiyo ultrasound, iyo inoshandiswa kuyera huwandu hwemvura mudunhu remutsipa wechibereko uye izvo zvinofanirwa kuitwa pakati pegumi nerimwe negumi nemana vhiki rekubata. Iyi bvunzo inoshandiswa kuverenga njodzi yemwana ane malformation kana chirwere, senge Down syndrome.

Kana kusagadzikana kana hutachiona hutachiona huripo, iyo fetus inowanzo kuunganidza fluid mu nape yemutsipa, saka kana kuyerwa kwe nuchal translucency kuri kuwedzerwa, pamusoro pe2,5 mm, zvinoreva kuti panogona kunge paine shanduko mukukura kwayo.

Chii chinonzi bvunzo

Chiyero che nuchal translucency hachisimbise kuti mwana ane chirwere chemajini kana kusakanganiswa, asi zvinoratidza kana mwana angave nenjodzi yekuwedzera yekuchinja uku.

Kana ukoshi hwebvunzo hwachinjwa, chiremba anozvara anozokumbira kumwe kuyedzwa senge amniocentesis, semuenzaniso, kusimbisa kana kwete kuongororwa.

Maitirwo azvo uye mareferensi kukosha

Iyo nuchal translucency inoitwa panguva yeimwe yekusununguka kusununguka uye, panguva ino, chiremba anoyera saizi uye huwandu hwemvura iri mudunhu kuseri kwemutsipa wemwana, pasina chikonzero cheimwe nzira yakakosha.

Iyo nuchal translucency tsika inogona kuve:

• Zvakajairika: asingasviki 2.5 mm
• Changed: yakaenzana kana yakakura kudarika 2.5 mm

Kuongororwa pamwe nekuwedzera kukosha hakuvimbisi kuti mwana anotambura nekuchinjika kupi, asi zvinoratidza kuti kune njodzi huru uye, nekudaro, chiremba anozvara achakumbira kumwe kuyedzwa, senge amniocentesis, inotora sampula yeamniotic fluid, kana cordocentesis, inoongorora tambo yeropa sampuro. Dzidza zvakawanda nezvekuti amniocentesis kana cordocentesis inogadzirwa sei.

Kana panguva yeiyo ultrasonography kune zvakare kushomeka kwemhino yemhino, njodzi yekumwe kusarongeka inowedzera zvakanyanya, nekuti pfupa remhino rinowanzove risipo mune syndromes.

Kuwedzera kune nuchal translucency, zera raamai uye nhoroondo yemhuri yechromosomal shanduko kana hosha yezvakaberekwa zvakakoshawo kuverenga njodzi yemwana yekuve neimwe yeshanduko idzi.

Nguva yekuita nuchal translucency

Bvunzo iyi inofanirwa kuitwa pakati pevhiki regumi nerimwe kusvika regumi nemana rekubata, sezvo iri iro nhumbu iri pakati pe45 ne84 mm pakureba uye zvinokwanisika kuverenga kuyerwa kweiyo nuchal translucency.

Inogona zvakare kuzivikanwa ne morphological ultrasound yeyekutanga trimester, nekuti, kuwedzera kune kuyerwa kwemutsipa wemwana, zvinobatsirawo kuona kukanganisika mumapfupa, moyo uye neropa tsinga.

Dzidza nezve mimwe miedzo inodiwa mune yekutanga trimester yekuzvitakura.
