Uma ucabanga ngomntwana omlindele, cishe uzizwa ujabule futhi wesaba kancane, akunjalo? Kuvamile ukuzibuza ukuthi umntwana uzoba nempilo noma kuzoba nezinkinga. Ngakho-ke, namuhla sizokhuluma ngokuhlolwa okukhethekile okwenziwa ngesikhathi sokukhulelwa ukuhlola ukuthi umntwana unezinkinga zofuzo noma ukukhubazeka kokuzalwa. Lokhu kubizwa ngokuthi i-Chorionic villus sampling , noma i-CVS ngamafuphi.
Kalula nje, iyini i-CVS?
Kalula nje, i-CVS ukuhlolwa okwenziwa ekuqaleni kokukhulelwa ukuthola izifo zofuzo, izinkinga ze-chromosome, kanye nezinye izinkinga zokuzalwa enganeni engakazalwa. Kuhilela ukuthatha isampula encane kakhulu yamaseli endaweni lapho i-placenta inamathela khona odongeni lwesibeletho.
Sibiza la maseli ngokuthi i-chorionic villi. Njengoba akhiwa ngeqanda elivundisiwe ngokwalo, la maseli aqukethe izakhi zofuzo zomntwana . Lokhu kusho ukuthi ngokuhlola la maseli, singathola umbono ocacile wolwazi lwezakhi zofuzo lomntwana.
Kungani lokhu kuhlolwa kwe-CVS kunconywa?
Lokhu kuhlolwa akuvamile ukunconywa yiwo wonke umuntu. Uma udokotela wakho ecabanga ukuthi unesifo esiyingozi , njengethuba elikhulu lokuba nengane enesifo sofuzo noma isici sokuzalwa, angase akuncome lokhu kuhlolwa.
Enye yezinzuzo ezinkulu zalokhu ukuthi ingakutshela ngokuqinisekile uma kunenkinga ekuqaleni kokukhulelwa kwakho. Ikakhulukazi uma ulindele amawele, imiphumela yokuhlolwa kwegazi okuvamile ayinembile kakhulu. Ezimweni ezinjalo, ukuhlolwa kwe-CVS kunganikeza impendulo ecacile. Kodwa-ke, izingozi zokuba nokuhlolwa kwe-CVS kumama okhulelwe onamawele ziphakeme kancane.
Yiziphi izifo ezingatholakala futhi ezingenakutholakala nge-CVS?
Kunezimo eziningana ezinkulu zezokwelapha ezingatholwa yilolu hlolo. Futhi kukhona nezinto olungenakuzibona. Ake sibheke ukuthi ziyini.
| Izimo ezibonakalayo | Izimo ezingabonakali |
|---|---|
| Ukukhubazeka kwe-chromosome njenge-Down syndrome. | Ukukhubazeka kwe-neural tube okuvulekile, njenge-spina bifida. |
| Izifo zofuzo ezifana ne-cystic fibrosis, isifo se-Tay-Sachs, kanye ne-sickle cell anemia. | (Kudingeka ezinye izivivinyo ukuze kutholakale izimo ezinjalo.) |
| Ngenxa yokuthi ubulili bomntwana bungatholakala, izifo eziqondene nobulili obubodwa kuphela (isib., ezinye izifo zemisipha ezivame kakhulu kubafana) zingatholakala. |
Lokhu kuhlolwa kubhekwa njengokunembile cishe ngo-98% ekutholeni amaphutha e-chromosome , okusho ukuthi kuwukuhlolwa okuthembekile kakhulu.
Yiziphi izinzuzo zokuhlolwa kwe-CVS?
Inzuzo enkulu yalokhu ukuthi kungenziwa ekuqaleni kokukhulelwa (ngokuvamile phakathi kwamasonto ayi-10-12). Kungenziwa ngaphambi kolunye uhlolo olubizwa ngokuthi i-amniocentesis. Imiphumela ngokuvamile ingatholakala zingakapheli izinsuku eziyi-10.
Ukuthola lolu hlobo lolwazi ekuqaleni kokukhulelwa kuwusizo olukhulu kubazali ekwenzeni izinqumo zesikhathi esizayo.
Cabanga nje, uma umbhangqwana unquma ukuqeda ukukhulelwa ngemva kokuthola imiphumela emibi, kungaba ngcono kakhulu ngempilo kamama ukusebenzisa leso sinqumo kusenesikhathi kunokulinda imiphumela ye-amniocentesis bese wenza kanjalo kamuva.
Ingabe kukhona izingozi ezihilelekile kulolu vivinyo?
Yebo, njenganoma yikuphi ukuhlolwa kwezokwelapha, kunezingozi ezithile. Ngenxa yokuthi lokhu kuhlolwa kwenziwa ekuqaleni kokukhulelwa, ingozi yokuphuphuma kwesisu ingaba phezulu kancane kune-amniocentesis. Kukhona futhi ingozi yokutheleleka.
Ezimweni ezingavamile kakhulu, ikakhulukazi uma lokhu kuhlolwa kwenziwa ngaphambi kwamasonto ayi-9, kube nemibiko yokukhubazeka eminweni yengane. Ngenxa yalesi sizathu, lokhu kuhlolwa kuvame ukwenziwa kuze kube amasonto ayi-10 .
Into ebaluleke kakhulu ukuthi udokotela wakho uzokutshela ngaphambi kokuba wenze lokhu kuhlolwa.Kubalulekile ukukhuluma nodokotela wakho ngalezi zingozi. Ikakhulukazi uma unezingane ezingamawele, qiniseka ukuthi lokhu kuhlolwa kwenziwa ngudokotela onolwazi ngalolu vivinyo.
Ukuhlolwa kwe-CVS kunconywa bani?
Odokotela ngokuvamile batusa ukuthi omama abanezici ezilandelayo eziyingozi bacabangele lolu vivinyo:
- Omama abaneminyaka engu-35 noma ngaphezulu (ingozi yokuba nengane enesici se-chromosome njenge-Down syndrome iyanda njengoba iminyaka ikhula).
- Imibhangqwana esevele inomntwana onesifo sokuzalwa noma enomlando womndeni walesi simo.
- Uma omunye wabazali ehlushwa ukukhubazeka kwe-chromosome noma isifo sofuzo esaziwayo.
- Omama abathole imiphumela engavamile kwezinye izivivinyo zofuzo ezenziwa ngesikhathi sokukhulelwa.
Udokotela wakho angakunikeza iseluleko esingcono kakhulu sokuthi lolu vivinyo lukulungele yini. Kodwa ekugcineni, isinqumo sokwenza lolu vivinyo noma cha kufanele senziwe nguwe nomlingani wakho, ngemva kwengxoxo ejulile nodokotela wakho.
Ukuhlolwa kwe-CVS kwenziwa kanjani?
Ngaphambi kokwenza lokhu kuhlolwa, wena nomlingani wakho nizothunyelwa ukuze niyokwelulekwa ngofuzo, lapho izinzuzo, ukungalungi, kanye nezingozi zalokhu kuhlolwa kuzochazwa khona ngokucacile.
Kube sekwenziwa i-ultrasound scan ukuhlola iminyaka yokukhulelwa komntwana kanye nendawo eqondile ye-placenta. Ukuhlolwa kwenziwa kamuva, ngokuvamile phakathi kwamasonto ayi-10 kuya kwangu-12 ngemva kokuya esikhathini kwakho kokugcina.
Kunezindlela ezimbili eziyinhloko zokuthola isampula yeseli kusuka ku-placenta.
Ngesitho sangasese sowesifazane (indlela ye-Transvaginal)
Kulokhu, kufakwa idivayisi ebizwa ngokuthi i-speculum esithweni sangasese sowesifazane, efana nokuhlolwa kwe-Pap. Bese kufakwa ithubhu elincane kakhulu lepulasitiki ngesitho sangasese sowesifazane bese likhuphuka umlomo wesibeletho. Ngaphansi kwesiqondiso se-ultrasound scan, leli thubhu liqondiswa ku-placenta, lapho kukhishwa khona isampula encane yamaseli.
Ngesisu (indlela ye-Transabdominal)
Ngale ndlela, efana nokuhlolwa kwe-amniocentesis, kufakwa inaliti encane kakhulu esiswini bese idluliselwa ku-placenta. Bese kuthathwa isampula yamaseli lapho.
Isampula yeseli etholwe ngale ndlela ithunyelwa elabhorethri. Lapho, amaseli akhuliswa oketshezini olukhethekile futhi ahlolwe izinsuku ezimbalwa. Imiphumela ephelele ingatholakala zingakapheli amasonto ama-2. Udokotela wakho uzokwazisa ngemiphumela.
Ingabe lokhu kuwuvivinyo olubuhlungu?
Ungase uzwe ubuhlungu, kodwa buzodlula ngokushesha . Ukuhlolwa konke kuzothatha imizuzu engama-30 kusukela ekuqaleni kuze kube sekupheleni. Kuthatha imizuzu embalwa kuphela ukuqoqa isampula.
Kwenzekani ngemva kokuhlolwa?
Kuzodingeka uphumule isikhashana ngemva kokuhlolwa. Ngakho-ke kungumqondo omuhle ukuza nothile ekhaya. Kufanele uphumule usuku lonke. Ngokuvamile welulekwa ukuthi ugweme ukuthwala izinto ezisindayo, ukuzivocavoca umzimba, kanye nocansi izinsuku ezintathu.
Ungase ube nokuqaqamba nokuphuma kwegazi okuncane, okuyinto evamile. Kodwa yazisa udokotela wakho ngakho. Okubaluleke kakhulu, uma ubona noma yikuphi ukuphuma kwamanzi esithweni sakho sangasese sowesifazane, tshela udokotela wakho ngokushesha.
Umlayezo Wokuya Nawe Ekhaya
- I-CVS iyisivivinyo esinembile kakhulu esingathola izimo zofuzo enganeni ekuqaleni kokukhulelwa.
- Lokhu kunezinzuzo (ukuthola imiphumela kusenesikhathi) kanye nezingozi ezincane (amathuba amancane kakhulu okuphuphuma kwesisu kanye nokutheleleka).
- Lokhu akulona ukuhlolwa kwawo wonke umuntu. Ngokuvamile kunconywa kulabo abanezici ezithile eziyingozi, njengokuba ngaphezu kweminyaka engama-35 ubudala.
- Ukuthi kufanele wenze lokhu kuhlolwa noma cha kuyisinqumo somuntu siqu phakathi kwakho nomlingani wakho. Khuluma nodokotela wakho ngokucophelela bese uthola lonke ulwazi ngaphambi kokwenza leso sinqumo.
- Landela yonke eminye imiyalelo kanye neminye enikezwe ngemva kokuhlolwa. Uma uhlangabezana nanoma yiziphi izimpawu ezingavamile, yazisa udokotela wakho ngokushesha.
