Ukuguquguquka kweNuchal: kuyini, kwenzelwa ini nokuthi kwenziwa kanjani

• Yini isivivinyo se-
• Kwenziwa kanjani futhi kubhekiswe amanani
• Uyenza nini i-nuchal translucency

Ukuguquguquka kwe-nuchal ukuhlolwa, okwenziwa ngesikhathi se-ultrasound, esetshenziselwa ukukala inani loketshezi esifundeni sentamo yombungu futhi lokho kufanele kwenziwe phakathi kwesonto le-11 nele-14 lokukhulelwa. Lokhu kuhlolwa kusetshenziselwa ukubala ubungozi bokuba nengane ene-malformation noma i-syndrome, njenge-Down syndrome.

Lapho ukungasebenzi kahle noma izifo zofuzo zikhona, umbungu uvame ukuqoqa uketshezi ku-nape yentamo, ngakho-ke uma isilinganiso se-nuchal translucency sikhuphuka, ngaphezu kuka-2.5 mm, kusho ukuthi kungaba noshintsho oluthile ekukhuleni kwalo.

Yini isivivinyo se-

Ukulinganiswa kwe-nuchal translucency akuqinisekisi ukuthi ingane inesifo sofuzo noma i-malformation, kepha kuyakhombisa ukuthi ingane inengozi eyengeziwe yokuba nalezi zinguquko noma cha.

Uma inani lokuhlola lishintshiwe, udokotela obelethisa uzocela ezinye izivivinyo ezifana ne-amniocentesis, isibonelo, ukuqinisekisa noma cha ukuxilongwa.

Kwenziwa kanjani futhi kubhekiswe amanani

Ukuguquguquka kwe-nuchal kwenziwa ngesinye se-ultrasound sangaphambi kokubeletha futhi, okwamanje, udokotela ulinganisa usayizi nenani liketshezi elisendaweni engemuva kwentamo yengane, ngaphandle kwesidingo sanoma iyiphi enye inqubo ekhethekile.

Amanani we-nuchal translucency angaba:

• Jwayelekile: ngaphansi kuka-2.5 mm
• Kushintshiwe: kulingana noma ngaphezulu kuka-2.5 mm

Ukuhlolwa okunenani elikhuphukile akuqinisekisi ukuthi ingane ihlangabezana nanoma yikuphi ukuguqulwa, kodwa kukhombisa ukuthi kunengozi enkulu futhi, ngakho-ke, udokotela obelethayo uzocela ezinye izivivinyo, njenge-amniocentesis, ethatha isampula le-amniotic fluid, noma i-cordocentesis, ehlola isampula yegazi lentambo. Funda kabanzi mayelana nokuthi kwenziwa kanjani i-amniocentesis noma i-cordocentesis.

Uma ngesikhathi se-ultrasonography kukhona futhi ukungabikho kwethambo lamakhala, ubungozi bokuthile okungalungile kwanda kakhulu, ngoba ithambo lamakhala ngokuvamile alikho ezimweni zama-syndromes.

Ngaphezu kokuguquguquka kwe-nuchal, ubudala bomama nomlando womndeni wezinguquko ze-chromosomal noma izifo zofuzo nakho kubalulekile ukubala ubungozi bengane bokuba nolunye lwalezi zinguquko.

Uyenza nini i-nuchal translucency

Lokhu kuhlolwa kufanele kwenziwe phakathi kwesonto le-11 kuya kwele-14 lokukhulelwa, njengoba kulapho umbungu uphakathi kuka-45 no-84 mm ubude futhi kungenzeka ukubala isilinganiso se-nuchal translucency.

Kungaziwa futhi nge-morphological ultrasound ye-trimester yokuqala, ngoba, ngaphezu kokulinganisa kwentamo yengane, kuyasiza futhi ukukhomba ukukhubazeka emathanjeni, enhliziyweni nasemithanjeni yegazi.

Funda ngezinye izivivinyo ezidingekayo ku-trimester yokuqala yokukhulelwa.
