I-chorionic biopsy

Enye yezifundo ezibaluleke kakhulu ezingayilumkisa owesifazane okhulelwe ngezifo eziyingozi zokufa yi-biopsy ye-chorionic.

Sizoveza lokho okushiwo yi-process - i-chorionic villus biopsy wuhlolo olukhethekile oluvumela ukuhlola isimo somntwana ngesikhathi sokuhlolwa. Yenziwa ngesikhathi sokukhulelwa emavikini angu-9-12 embryonic ngaphansi kokuqondiswa kwe-ultrasound. Imiphumela ye-biopsy ye-chorion ingatholakala emva kwezinsuku ezingu-2-3. Ukuhamba kwesikhotho kuyathathwa ngevolumu ye-1-15 mg kumvamisa wokuthola inani elidingekayo lokuhlaziywa kwe-chorion ye-villus: 94-99.5%.

Izinkomba nokuphikisana nokuhlaziywa kwe-chorion ye-villus

Ukuhlolwa kuvumela ukukhomba kusengaphambili izinkinga ezikhona ezihlobene nezakhi zofuzo zomntwana. Okubaluleke ngokukhethekile ukuhlolwa lapho kukhona izifo ezithinta izifo ezihlotsheni zomama ozayo noma ubaba wengane.

Isiboniso sokuhlolwa:

• ubudala bomama olindelekile eminyakeni engama-35 nangaphezulu;
• ukuthutha kwesiguquko sezakhi noma ukungajwayelekile kwe-chromosomal;
• imiphumela ye-sonography;
• Ukulinganisa kwesikhala sekhalenda kungaphansi kwama-3 mm emasontweni angu-10-14.

Futhi isibonakaliso sokuthatha isikhathi sokugqoka siwukuthi i-anamnesis eyakhiwe ngokweqile noma eyinkimbinkimbi (ukuba khona kwa-anamnesis esiphethweni sokuthi ingane ingazalwa nge-VLP, isifo sengculazi noma se-chromosomal).

Ukungafani kokuhlolwa kungaba:

• isimo somkhuhlane wesifazane;
• ukuphuma kwegazi kusuka emgunyeni wokuzala;
• ukukhushulwa kwezifo ezingapheliyo;
• ukungakwazi kahle komlomo wesibeletho;
• ukungatholakali kwamathisamu e-chorionic;
• Isilonda esithathelwanayo sesikhumba sodonga lwesisu sangaphakathi;
• inqubo yokubambelela ebizwa nge-pelvis encane.

Ukuhlaziywa kwama-chorion

Ukuhlaziywa kwe-chorion yi-biopsy ye-villi ye-chorion, okungukuthi, i-membrane yangaphandle ehlanganiswe ne-villi. Kungenziwa ngezindlela ze-transcervical and transabdominal. Ukuhluka kwe-Transcervical kuyinto ucingo lwe-villi yi-catheter noma i-biopsy iphoqa emgodini wesibeletho. Ngendlela yokuguqula umzimba, amasampuli athathwa ngesigxobo sangasese sangasese nesinaliti eside esincane. Ukukhethwa kwendlela kuncike endaweni ye-chorion esibelethweni.

Ubani owenza i-chorionic biopsy, uyazi ukuthi ukuhlaziywa kwe-villus ye-chorion, ikakhulukazi ezigabeni zokuqala zokukhulelwa, kuqinisekisa umphumela osheshayo, ukuhlolwa kwe-DNA (ukuhlolwa kobuhlobo) nokuzimisela ubulili bomntwana .

I-chorion biopsy - imiphumela engenzeka

Ukuzivocavoca kubonisa ukuthi i-biopsy ye-chorionic villi noma i-amniocentesis ingenabuhlungu futhi iphephile namuhla. Ngokwenza kanjalo, linikeza imiphumela enembile. I-biopsy ye-chorion ngesikhathi sokukhulelwa ayilimazi ingane. i-villi, ezithathwa ukuze zivivinywe, zinyamalale ngokuthuthukiswa kwe-fetus, lokhu kuhlaziywa akukwenzi usongo lokukhulelwa (okungenani u-1%). Iphesenti yokuhlukumeza isincane kakhulu, futhi umphumela unembile kangangokuthi abesifazane abaningi banquma ukubeka engozini futhi bafunde mayelana nokuxilongwa kwe-fetus ngokushesha ngangokunokwenzeka. Noma kunjalo, odokotela baxwayisa ngezinkinga ezinokwenzeka ezifana nobuhlungu, ukutheleleka, ukuphuma kwegazi, ukukhipha isisu, okungenzeka ngemva kokuthola ukuxilongwa ukuhlolwa.

Kungakhathaliseki ukwenza i-biopsy ye-chorion?

Kungakhathaliseki ukwenza i-biopsy ye-chorionic noma cha, owesifazane kuphela anganquma, acabangele iseluleko sikadokotela futhi ahlaziye izingozi ezingenzeka. Imithi yesimanje yenza konke okusemandleni ukukhipha ithuba lokuzalwa kwengane enezifo ezifuywayo ezithintekayo kanye nezinguquko ezingalungile ze-chromosomal. Ukuzihlola nokuhlolwa okubonisa ukuthi omama esikhathini esizayo ezikhungweni zemithi yokubeletha bangavunyelwa ukuvimbela ukwehlukana okungenzeka ekuthuthukiseni ingane futhi kuqinisekiswe ukuzalwa kwengane enempilo.
