Biopsy

Enye yezona zibalulekileyo zifundo ezingayilumkisa umfazi okhulelweyo malunga nezifo eziyingozi eziyingozi ze-chorionic biopsy.

Siza kubonakalisa intsingiselo yenkqubo - i-chorionic villus biopsy yimvavanyo ekhethekileyo evumela ukuba uhlolisise imeko yomntwana ngexesha lokuvavanya. Yenziwa ngexesha lokukhulelwa kwiiveki ezingama-9 ukuya kwe-embryonic phantsi kolawulo lwe-ultrasound. Iziphumo ze-biopsy ye-chorion zingafumaneka emva kweentsuku ezingama-2-3. Ukugqithwa kwesikhotho kuyathathwa kwimiqulu ye-1-15 mg kwixesha lokufumana ixabiso elifunekayo ukuhlaziywa kwe-chorion ye-villus: 94-99.5%.

Iimpawu kunye nokuchasene nokuhlalutya kwe-villus chorion

Uvavanyo luvumela ukuchonga kwangaphambili iingxaki ezinokubambisana nemfuza yomntwana. Okubaluleke ngakumbi ukuvavanya phambi kwezifo ezizaliswayo kwiintsapho zomzali ozayo okanye uyise wesisu.

Isibonakaliso sovavanyo:

• ubudala bomama olindelekileyo iminyaka engama-35 nangaphezulu;
• ukuthuthwa komgubo wokuguqulwa komzimba okanye i-chromosomal engavamile;
• iziphumo zoonobumba;
• Imilinganiselo yendawo yekhola ingaphantsi kwe-3 mm kwiiveki ezi-10-14.

Kwakhona isibonakaliso sokuthatha i-puncture ngumthwalo ogqithisiweyo ngokwemfuyo okanye kwi-anamnesis engqongqo (ubukho kwi-anamnesis yesigqibo sokuba umntwana angazalwa nge-VLP, isifo se-monogenic or chromosomal).

Ukungqinelana novavanyo kunoku:

• imeko yesifo somfazi;
• Ukuphuma kwegazi ukusuka kwindlela yokuzala;
• ukunyanzeliswa kwezifo ezingapheliyo;
• ukungaqondi kakuhle komlomo wesibeleko;
• ukungenafikeleleki kwezicubu ze-chorionic;
• Isilonda esithathelwanayo esikhumbeni sodonga lwesisu sangaphakathi;
• Inkqubo yokubambelela kwi-pelvis encinci.

Uhlalutyo lwe-chorion

Uhlalutyo lwenqweno yi-biopsy ye-villi ye-chorion, okuthi, i-membrane yangaphandle ehlanganiswe ne-villi. Ingenziwa ngeendlela ze-transcervical and transabdominal. Utshintsho lwe-Transcervical yi-fence ye-villi yi-catheter okanye i-biopsy iphosa kwi-cervix. Ngendlela yokuguqula umzimba, iisampuli zithathwa kwisigxina sangasemva kwesisu kunye nenaliti ende ende. Ukukhethwa kwendlela kuxhomekeke kwindawo yendawo yokuvumba kwintsholongwane.

Ngubani owenza i-chorionic biopsy, uyazi ukuba uhlalutyo lwe-villus ye-chorion, ikakhulukazi kumanyathelo okuqala okukhulelwa, luqinisekisa umphumo osheshayo, uvavanyo lwe-DNA (uvavanyo lwezantathu) kunye nokuzimisela kwesondo lomntwana .

I-chorion biopsy - iziphumo ezinokwenzeka

Ukuziqhelanisa kubonisa ukuba i-biopsy ye-chorionic villi okanye i-amniocentesis ayikho intlungu kwaye iphephile namhlanje. Ngokwenza njalo, inika iziphumo ezichanekileyo. I-biopsy ye-chorion ngexesha lokukhulelwa ayilimazi umntwana. i-villi, ezithathwa ukuhlolwa, zinyamalale kunye nophuhliso lwe-fetus, oku kuhlalutya akuyi kubangela ingozi yokukhulelwa (ubuninzi be-1%). Ipesenteji yokulahleka kwezinto ezimbi kakubi kakhulu, kwaye isiphumo sichanekile kangangokuba abaninzi abafazi banquma ukubeka umngcipheko baze bafunde malunga nokuxilongwa kwe-fetus ngokukhawuleza. Nangona kunjalo, oogqirha bayalumkisa ngeengxaki ezinokwenzeka ezifana nentlungu, ukusuleleka, ukuphuma kwamanzi, ukukhupha isisu, okuza kwenzeka emva kokuxilongwa vavanyo.

Ingaba ukwenza i-biopsy ye-chorion?

Ingaba ukwenza i-chorionic biopsy okanye akunjalo, ngowesifazane kuphela onokugqiba isigqibo, eqwalasela ingcebiso ngogqirha nokuhlalutya ingozi. Iyeza zanamhlanje zenza yonke imizamo yokukhuphela ngaphandle kokuzalwa komntwana kunye nezifo ezizalisiweyo ezivelisiweyo kunye nezinguquko ezingathandekiyo ze-chromosomal. Ukuxilonga kunye neemvavanyo ezibonisa ukuba oomama bexesha elizayo kumaziko enonyango okhulayo banokuvunyelwa ukuthintela ukuphungulwa okwenzekayo ekuphuculweni komntwana kunye nokuqinisekisa ukuzalwa komntwana onempilo.
