Teko ea Nuchal translucency

Teko ea nuchal translucency e lekanya botenya ba nuchal. Ena ke sebaka sa lisele tse ka morao molaleng oa lesea le e-s'o hlahe. Ho lekanya botenya bona ho thusa ho lekola kotsi ea Down syndrome le mathata a mang a lefutso ho lesea.

Mofani oa hao oa tlhokomelo ea bophelo o sebelisa mpa ea ultrasound (eseng ea ka botšehaling) ho metha lesaka la nuchal. Bana bohle ba e-so hlahe ba na le mokelikeli mokokotlong oa melala ea bona. Ho lesea le nang le Down syndrome kapa mathata a mang a lefutso, ho na le mokelikeli o mongata ho feta o tloaelehileng. Sena se etsa hore sebaka se shebahale se le motenya.

Ho etsoa tlhahlobo ea mali ea mme. Hammoho, liteko tsena tse peli li tla tseba hore na ngoana a ka ba le Down syndrome kapa lefu le leng la lefutso.

Ho ba le senya e felletseng ho tla fana ka setšoantšo se setle sa ultrasound. U ka kopuoa ho noa likhalase tse 2 ho isa ho tse 3 tsa mokelikeli hora pele ho tlhahlobo. U SE KE ua ntša metsi pele ho ultrasound.

U kanna oa ba le bothata bo tsoang khatellong ea senya nakong ea ultrasound. Jel e sebelisitsoeng nakong ea tlhahlobo e kanna ea utloa e bata ebile e le metsi. U ke ke ua utloa maqhubu a ultrasound.

Mofani oa hau a ka eletsa tlhahlobo ena ho lekola ngoana oa hau bakeng sa Down syndrome. Bakhachane ba bangata ba etsa qeto ea ho etsa tlhahlobo ena.

Nuchal translucency hangata e etsoa lipakeng tsa beke ea 11 le ea 14 ea bokhachane. E ka etsoa pejana nakong ea bokhachane ho feta amniocentesis. Ena ke teko e 'ngoe e lekang liphoso tsa tsoalo.

Mokelikeli o tloaelehileng mokokotlong oa molala nakong ea ultrasound o bolela hore ho ka etsahala hore ngoana oa hau a se ke a ba le Down syndrome kapa lefu le leng la lefutso.

Tekanyo ea Nuchal translucency e eketseha ka lilemo tsa bokhachane. Ena ke nako e lipakeng tsa kemolo le pelehi. Ha litekanyo li phahama ha li bapisoa le masea a lilemo tse tšoanang tsa bokhachane, kotsi e phahame ke mafu a itseng a lefutso.

Litekanyo tse ka tlase li nkuoa li le kotsi e tlase bakeng sa mathata a liphatsa tsa lefutso:

• Ka libeke tse 11 - ho fihlela ho 2 limilimithara
• Ka libeke tse 13, matsatsi a 6 - ho fihlela ho 2.8 mm

Metsi a mangata ho feta a tloaelehileng mokokotlong oa molala a bolela hore ho na le kotsi e kholo ea Down syndrome, trisomy 18, trisomy 13, Turner syndrome, kapa lefu la pelo la congenital. Empa ha e bolele hantle hore lesea le na le Down syndrome kapa lefu le leng la lefutso.

Haeba sephetho se sa tloaelehang, ho ka etsoa liteko tse ling. Boholo ba nako, teko e 'ngoe e entsoeng ke amniocentesis.

Ha ho na likotsi tse tsebahalang tse tsoang ho ultrasound.
