Uma ungumama ozoba nomntwana, udokotela wakho kungenzeka ukuthi ukutshelile ngokuhlolwa okukhethekile okungakutshela okuningi ngempilo yomntwana kusenesikhathi. I-CVS ingenye yezivivinyo ezinjalo. Igama lingase lizwakale liyesabeka kancane, kodwa liyisivivinyo esibalulekile komama abaningi. Ake sibheke ukuthi kuyini, kungani kwenziwa, ukuthi kwenziwa kanjani, nokuthi kuyinto okufanele uyesabe yini.
Kuyini ngempela lokhu kuhlolwa kwe-CVS?
Kalula nje, i-CVS (Chorionic Villus Sampling) ukuhlolwa okukhethekile okwenziwa ngesikhathi sokukhulelwa. Kusetshenziselwa ukuhlola ukuthi ingane yakho engakazalwa inazo yini izifo zofuzo noma amaphutha okuzalwa. Udokotela wakho uzoncoma lokhu kuhlolwa kuphela uma kukhona okusolakala ukuthi ingane yakho inazo noma yiziphi izinkinga zofuzo noma amaphutha okuzalwa.
Kodwa lokhu akulona ukuhlolwa okuphoqelekile. Lokhu kuyinto okufanele uyinqume ngokuphelele ngokusekelwe ezifisweni zakho. Yenza lokhu kuphela uma unomuzwa wokuthi kulungile kuwe ngemva kokuxoxa ngazo zonke izinzuzo, izinkinga kanye nezingozi nodokotela wakho.
Lokhu kuhlolwa kuvame ukwenziwa phakathi kwamasonto ayi-10 kuya kwayi-13 okukhulelwa. Enye inzuzo yalokhu kuhlolwa ukuthi kunganquma ngokunembile ubulili bomntwana (kungakhathaliseki ukuthi intombazane noma umfana).
Ungenza kanjani isivivinyo?
Okwenzekayo kulokhu ukuthi isampula encane kakhulu yamaseli ithathwa ku-placenta yengane yakho. Sibiza la maseli ngokuthi `(Chorionic Villi)`. Manje ungase uzibuze ukuthi kungani isampula ithathwa ku-placenta hhayi kumntwana. Cabanga ngakho, umntwana wakhiwe yiseli elilodwa. Izingxenye ze-placenta nazo zakhiwe ngalawo maseli afanayo. Ngakho-ke, ulwazi lwezakhi zofuzo lomntwana lukulezi zingxenye ze-placenta. Ngamanye amazwi, la maseli afana namawele ezakhi zofuzo zomntwana. Ngakho-ke leli sampula leseli liyathathwa lithunyelwe elabhorethri futhi lihlaziywe ukuze kubonwe ukuthi umntwana unezinkinga zofuzo yini.
Ubani okufanele ahlolwe i-CVS?
Lokhu kuhlolwa kwe-CVS akulona ukuhlolwa okuvamile kwabo bonke abesifazane abakhulelwe. Udokotela wakho angase akuncome uma unezici ezithile eziyingozi, noma uma uke wabona noma yikuphi ukukhubazeka ekuskeni kwangaphambilini noma kolunye ukuhlolwa.
Udokotela wakho angakutshela ngalolu vivinyo ezimweni ezilandelayo:
- Uma usuvele unengane enesifo esihambisana nofuzo.
- Uma uneminyaka engaphezu kwengu-35 ubudala (ngesikhathi sokukhulelwa). Ingozi yokuba nezinkinga ezithile zofuzo iyanda kancane njengoba ukhula.
- Uma imiphumela yokuskena kwangaphambilini noma olunye uvivinyo ikhombisile ukuthi ingane isengozini enkulu yokuthola isifo sofuzo.
- Uma wena, umyeni wakho, noma omunye umuntu emndenini wakho enesifo noma eke waba naso.
Into ebalulekile ukuthi unqume ukuthi uzohlolwa noma cha, noma ngabe unalezi zici eziyingozi. Unelungelo lokukweqa lokhu.
Kwezinye izimo, udokotela wakho angase akutshele ukuthi ungakwenzi lokhu kuhlolwa. Lokhu kufaka phakathi:
- Uma uke waba nokopha esithweni sangasese sowesifazane phakathi nalokhu kukhulelwa.
- Uma unesifo, ikakhulukazi isifo esithathelwana ngocansi (STI).
Yiziphi izifo ezingatholakala ngalesi sivivinyo?
I-CVS ibheka kakhulu izinkinga ngama-chromosome omntwana. Ama-chromosome afana namaphakethe amancane agcina ulwazi lwezakhi zofuzo lomzimba wethu (i-DNA). Uma kukhona ushintsho kulawa, njengokwanda, ukwehla, noma ukuphuka kwe-chromosome, umntwana angase abe nesifo sokuzalwa.
Nazi ezinye zezimo eziyinhloko ezingatholakala ngokuhlolwa kwe-CVS:
- I-Down syndrome (i-Down syndrome noma i-trisomy 21): Lesi yisimo sofuzo esikhulunywa kakhulu ngaso phakathi kwethu.
- I-cystic fibrosis
- Isifo se-sickle cell
- Isifo sikaTay-Sachs
- I-Trisomy 18 (i-Trisomy 18 noma i-Edward syndrome)
- I-Trisomy 13 (i-Trisomy 13 noma i-Patau Syndrome)
Ingabe kukhona izinto ukuhlolwa kwe-CVS okungenakuzibona?
Yebo. Ayikwazi ukubona zonke izinkinga zokuzalwa. Ayikwazi ukubona izinto ezifana nezinkinga ze-neural tube (NTDs). Isibonelo, ayikwazi ukubona inkinga ebizwa ngokuthi i-spina bifida. Kunezinye izivivinyo ezifana ne-amniocentesis ezingakwazi ukubona izinto ezinjalo.
Futhi, i-CVS ayikwazi ukubona amaphutha esakhiwo njengembobo enhliziyweni yengane noma udebe oluqhekekile noma ulwanga. Lokhu kungatholakala nge-anomaly scan, eyenziwa phakathi kwamasonto ayi-18 nama-20 okukhulelwa.
Kwenzekani ngaphambi nangesikhathi sokuhlolwa?
Ngaphambi kokuthi uhlele ukuhlolwa kwakho, uzohlangana nomeluleki wezakhi zofuzo noma uchwepheshe wezakhi zofuzo. Bazokuchazela izinzuzo, izingozi, kanye nenqubo yonke. Bazokubuza noma yimiphi imibuzo noma ukukhathazeka ongase ube nakho. Bazobe sebekwenza ukuskena ukuze bathole ukuthi ukhulelwe amasonto amangaki. Usuku olungcono kakhulu lokuhlolwa kwe-CVS luzonqunywa ngokusekelwe kulokho.
Lokhu kuhlolwa kwenziwa kanjani? Ingabe kubuhlungu?
Lokhu kuhlolwa akubuhlungu kakhulu, kodwa ungase uzizwe ungakhululekile. Kunezindlela ezimbili eziyinhloko zokwenza lokhu. Udokotela wakho uzokhetha indlela engcono kakhulu kuye ngokuthi i-placenta yakho ikuphi.
1. Ngesitho sangasese sowesifazane (i-Transcervical):Kulokhu, kufakwa idivayisi ebizwa ngokuthi i-speculum esithweni sakho sangasese sowesifazane, bese kudluliswa ipayipi elincane kakhulu lepulasitiki lidlulela kulo lidlule esibelethweni liye lapho kukhona khona i-placenta. Konke lokhu kwenziwa ngaphansi kokubhekwa kwe-scan. Ngemuva kwalokho, kuthathwa isampula encane yamaseli avela ku-placenta ngaleyo payipi.
2. I-Transabdominal: Kule ndlela, kufakwa inalithi encane kakhulu esikhumbeni sesisu sakho, iqondiswa yi-scan, endaweni lapho kukhona khona i-placenta, bese kuthathwa isampula yeseli. Uma wenza le ndlela, ngeke uzwe ubuhlungu obukhulu ngoba inani elincane lomuthi lifakwa ukuze kufe i-nail kuphela endaweni lapho kufakwa khona inalithi.
Noma ngabe yikuphi, yonke inqubo ithatha imizuzu engaphansi kwengu-30.
Kwenzekani ngemva kokuhlolwa?
Uzokwazi ukuya ekhaya ngokushesha ngemva kokuphela kokuhlolwa. Kungcono ukuphumula usuku lonke. Iningi labantu lingabuyela emisebenzini evamile ngosuku olulandelayo. Kodwa-ke, udokotela wakho uzokutshela ukuthi ugweme imisebenzi efana nocansi, ukuzivocavoca umzimba, kanye nokuphakamisa izinto ezisindayo izinsuku ezimbili kuya kwezintathu.
Ngemva kokuhlolwa, ungase ube nokuqaqamba okuncane esiswini, okufana nokuya esikhathini kwakho. Ungase futhi ube nokopha okuncane kakhulu kwesitho sangasese sowesifazane. Lokhu kuvamile. Uma ukuhlolwa kwenziwe ngesisu, ungase uzizwe ubuhlungu lapho inaliti ifakiwe khona.
Yiziphi izingozi nezinzuzo zokuhlolwa kwe-CVS?
Njenganoma yikuphi ukuhlolwa kwezokwelapha, kunengozi encane. Kodwa iphansi kakhulu. Kudingeka senze isinqumo ngokusiqhathanisa nezinzuzo.
| Izingozi | Izinzuzo |
|---|---|
| Ukuphuphuma Kwesisu: Lokhu kuyinto abantu abaningi abayesabayo. Kodwa-ke, ingozi yokuphuphuma kwesisu ngenxa yokuhlolwa kwe-CVS ingaphansi kuka-1%. Lokho kusho ukuthi bangaphansi koyedwa kubantu abayi-100 abakwenzile. | Ukuthola imiphumela kusenesikhathi: Inzuzo enkulu ukwazi isimo somntwana ekuqaleni kokukhulelwa, okukunikeza isikhathi esengeziwe sokwenza izinqumo nokulungiselela ikusasa ngokwengqondo. |
| Ukutheleleka: Njenganoma iyiphi inqubo yezokwelapha, kunengozi encane kakhulu yokutheleleka. | Ukunemba okuphezulu:Lolu vivinyo lunembe ngo-99%, ngakho-ke ungaqiniseka ngokuphelele ngemiphumela. |
| Ukukhubazeka kwezitho: Akuvamile kakhulu, ikakhulukazi uma lokhu kuhlolwa kwenziwa ngaphambi kwamasonto ayi-10, kube nemibiko yokuthi ingane ingase ibe nesici kwenye yezingalo noma imilenze yayo. Yingakho kwenziwa ngesikhathi esifanele. | Isikhathi sokulungiselela: Uma imiphumela ikhombisa ukuthi ingane izodinga noma yiluphi ukwelashwa okukhethekile ngemva kokuzalwa, lokhu kuzokusiza ukuthi ulungiselele lezo zinto kusenesikhathi futhi wazise isibhedlela. |
| Ezinye izingozi ezincane: Kunezingozi ezincane kakhulu njengokuphuma kwegazi ngokweqile, ukuvuza koketshezi lwe-amniotic oluzungeze ingane, kanye nokuzwela kwe-Rh. | Induduzo yengqondo: Uma kukhona izinto eziyingozi futhi imiphumela yokuhlolwa ibuya iqinisekile, induduzo yengqondo yokukwazi ukuchitha ingxenye esele yokukhulelwa ngenjabulo ngaphandle kokwesaba noma ukungabaza ayinakuqhathaniswa. |
Kuthatha isikhathi esingakanani ukuthi imiphumela ibuye? Kuthiwani uma imiphumela ilungile?
Ngemva kokuba isampula yeseli isithunyelwe elabhorethri, amaseli ayakhuliswa futhi ahlolwe. Eminye imiphumela yokuqala iyatholakala ezinsukwini ezimbalwa. Kodwa-ke, ezinye izimo zithatha isikhathi eside ukuhlolwa. Ngakho-ke kungathatha izinsuku eziyi-10 kuya emavikini amabili ukuthola umbiko ogcwele. Udokotela wakho noma umeluleki wezakhi zofuzo uzokushayela ucingo ukuze akutshele ngemiphumela.
Nakuba ukuhlolwa kwe-CVS kunembile ngo-99%, akukwazi ukubikezela ubucayi besimo. Ezimweni ezimbalwa kakhulu, cishe u-1%-2%, ukukhubazeka kungase kukhawulelwe ku-placenta futhi kungabi nomthelela enganeni.
Uma imiphumela ngeshwa iqinisekisa ukuthi ingane yakho inesifo sofuzo, kuzoba isikhathi esinzima kakhulu kuwe. Ngaleso sikhathi, udokotela wakho kanye nomeluleki wakho bazokhuluma nawe ngokucacile ngalesi simo, ukuthi sizothinta kanjani ikusasa lomntwana wakho, kanye nezinketho ezitholakalayo kuwe. Ngaleso sikhathi, kufanele ukhulume nomyeni wakho futhi ucabange ngokucophelela ngezinyathelo ezilandelayo.
Uyini umehluko phakathi kwe-CVS ne-Amniocentesis?
Abantu abaningi badida lezi zivivinyo ezimbili. I-Amniocentesis ingenye indlela yokuhlola ebheka isimo sofuzo somntwana. Kunomehluko omkhulu phakathi kwalokhu okubili.
| Iphuzu | Ukuhlolwa kwe-CVS | Ukuhlolwa kwe-Amniocentesis |
|---|---|---|
| Isikhathi sokukwenza | Ekuqaleni kokukhulelwa, phakathi kwamasonto e -10-13 . | Ukukhulelwa okuphakathi, ngemva kwamasonto angu -16 . |
| Isampula ethathiwe | Amaseli athathwe ku-placenta (i-Chorionic villi) | Uketshezi lwe-amniotic oluzungeze umntwana |
| Yini engabonakala | Ukukhubazeka kwe-chromosome kanye nezifo zofuzo. | Ukukhubazeka kwe-chromosome, izifo zofuzo kanye nokukhubazeka kwe-neural tube (NTDs) . |
| Ingozi yokuphuphuma kwesisu | Kuphakeme kancane (ngaphansi kuka-1%). | Kancane kancane. |
Udokotela wakho uzochaza ukuthi yikuphi ukuhlolwa okukulungele, kuye ngesimo sakho.
