Nuchal translucency bvunzo

Iyo nuchal translucency bvunzo inoyera iyo nuchal fold ukobvu. Iyi inzvimbo yetishu kumusana kwemutsipa wemwana asati azvarwa. Kuyera ukuru kunobatsira kuongorora njodzi yeDown syndrome uye mamwe matambudziko emagene mumwana.

Wako wekuchengeta hutano anoshandisa dumbu ultrasound (kwete mukadzi) kuyera nuchal peta. Vese vacheche vasina kuberekwa vane imwe fluid kumashure kwemutsipa wavo. Mucheche ane Down syndrome kana zvimwe zvinokonzerwa nemagene, pane zvakawanda zvinowedzera mvura kupfuura zvakajairwa. Izvi zvinoita kuti nzvimbo iite seyakafuta.

Kuongororwa kweropa kwaamai kunoitwawo. Pamwe chete, bvunzo mbiri idzi dzinotaurira kana mwana angave aine Down syndrome kana imwe geni kusagadzikana.

Kuva nechikwata chakazara kuchapa yakanakisa ultrasound mufananidzo. Unogona kukumbirwa kunwa magirazi maviri kusvika matatu emvura paawa pasati pabvunzo. Usatete pamberi pe ultrasound yako.

Iwe unogona kunge uine kusagadzikana kubva pakumanikidza pane yako dundira panguva yeiyo ultrasound. Iyo gel inoshandiswa panguva yekuedzwa inogona kunzwa kutonhora uye kunyorova. Iwe hauzonzwa iwo masaisai e ultrasound.

Wako mupi anogona kuraira iyi bvunzo kuongorora mwana wako kune Down syndrome. Vakadzi vazhinji vane nhumbu vanosarudza kuita bvunzo iyi.

Nuchal translucency inowanzoitwa pakati pegumi nerimwe negumi nemana vhiki rekubata. Inogona kuitwa kare mukuzvitakura kupfuura amniocenteis. Iyi ndiyo imwe bvunzo inotarisa kuremara kwekuzvarwa.

Iyo yakajairwa huwandu hwemvura kumashure kwemutsipa panguva ye ultrasound zvinoreva kuti hazviite kuti mwana wako ave ne Down syndrome kana imwe geni kusagadzikana.

Nuchal translucency kuyerwa kunowedzera nezera rekubata. Iyi inguva iri pakati pekubata pamuviri nekusununguka. Iyo yakakwira iyo chiyero ichienzaniswa nevana vacheche vezera rimwe rekubata, iyo inowedzera njodzi iri yehumwe hutachiona kusagadzikana.

Izvo zviyero pazasi zvinoonekwa seyakaderera njodzi yezvinetso zvemagetsi:

• Pamasvondo gumi nerimwe - kusvika 2 mm
• Pamasvondo gumi nematatu, mazuva matanhatu - kusvika 2.8 mm

Zvimwe zvinwiwa kupfuura zvakajairika kumashure kwemutsipa zvinoreva kuti kune njodzi yakanyanya ye Down syndrome, trisomy 18, trisomy 13, Turner syndrome, kana chirwere chepfungwa chepfungwa. Asi hazviudze zvechokwadi kuti mwana ane Down syndrome kana imwe geni kusagadzikana.

Kana mhedzisiro yacho isina kujairika, mimwe miedzo inogona kuitwa. Kazhinji yenguva, imwe bvunzo inoitwa amniocentesis.

Iko hakuna njodzi dzinozivikanwa kubva kune ultrasound.
