Xa ucinga ngomntwana omlindeleyo, mhlawumbi uziva uchulumancile kwaye uloyiko kancinci, akunjalo? Kuqhelekile ukuzibuza ukuba umntwana uza kuba sempilweni okanye kuza kubakho naziphi na iingxaki. Ngoko ke, namhlanje siza kuthetha ngovavanyo olukhethekileyo olwenziwa ngexesha lokukhulelwa ukujonga ukuba umntwana uneengxaki zofuzo okanye iziphene zokuzalwa. Oku kubizwa ngokuba yiChorionic villus sampling , okanye iCVS ngamafutshane.
Ngamafutshane, yintoni i-CVS?
Ngamafutshane, i-CVS luvavanyo olwenziwa kwangethuba ekukhulelweni ukuze kufunyanwe izifo zemfuza, iingxaki ze-chromosome, kunye nezinye iziphene zokuzalwa kumntwana ongekazalwa. Lubandakanya ukuthatha isampuli encinci kakhulu yeeseli kwindawo apho i-placenta inamathela khona eludongeni lwesibeleko.
Ezi seli sizibiza ngokuba yi-chorionic villi. Ekubeni zenziwe ngeqanda elivundisiweyo ngokwalo, ezi seli ziqulathe izakhi zofuzo zomntwana . Oku kuthetha ukuba ngokuhlola ezi seli, sinokufumana umbono ocacileyo wolwazi lwezakhi zofuzo lomntwana.
Kutheni le nto olu vavanyo lweCVS lucetyiswa?
Olu vavanyo aluqhelekanga ukucetyiswa ngumntu wonke. Ukuba ugqirha wakho ucinga ukuba unobungozi , njengokuba nethuba eliphezulu lokuba nomntwana onesifo sofuzo okanye isiphene sokuzalwa, unokucebisa olu vavanyo.
Enye yezona nzuzo zinkulu zoku kukuba inokukuxelela ngokuqinisekileyo ukuba kukho ingxaki kwangethuba kakhulu ekukhulelweni kwakho. Ingakumbi ukuba ulindele amawele, iziphumo zovavanyo lwegazi oluqhelekileyo azichanekanga kakhulu. Kwiimeko ezinjalo, uvavanyo lwe-CVS lunokunika impendulo ecacileyo. Nangona kunjalo, iingozi zokuba novavanyo lwe-CVS kumama okhulelweyo onamawele ziphezulu kancinci.
Ziziphi izifo ezinokufunyanwa kwaye zingenakufunyanwa yi-CVS?
Kukho iimeko ezininzi ezibalulekileyo zempilo ezinokuthi olu vavanyo luzibone. Kukwakho nezinto olungenakuzibona. Makhe sijonge ukuba zeziphi.
| Iimeko ezibonakalayo | Iimeko ezingabonakaliyo |
|---|---|
| Ukuphazamiseka kwe-chromosome okufana ne-Down syndrome. | Iziphene zetyhubhu ye-neural ezivulekileyo, ezifana ne-spina bifida. |
| Izifo zemfuza ezifana ne-cystic fibrosis, isifo seTay-Sachs, kunye ne-sickle cell anemia. | (Kufuneka ezinye iimvavanyo ukuze kufunyaniswe ezo meko.) |
| Ngenxa yokuba isini somntwana sinokuchongwa, izifo ezithile zesini esinye kuphela (umz., ezinye izifo zemisipha ezixhaphake kakhulu kubafana) zinokuchongwa. |
Olu vavanyo luthathwa njengoluchanekileyo malunga ne-98% ekufumaneni iziphene ze-chromosome , oko kuthetha ukuba luvavanyo oluthembekileyo kakhulu.
Zithini iingenelo zovavanyo lweCVS?
Eyona nzuzo inkulu yoku kukuba ingenziwa kwangethuba ekukhulelweni (ngesiqhelo phakathi kweeveki ezili-10-12). Ingenziwa kwangethuba kunolunye uvavanyo olubizwa ngokuba yi-amniocentesis. Iziphumo zihlala zifumaneka kwiintsuku ezili-10.
Ukufumana olu hlobo lolwazi kwangethuba ekukhulelweni kunceda kakhulu abazali ekwenzeni izigqibo zexesha elizayo.
Khawucinge nje, ukuba isibini sigqiba ekubeni sikhuphe ukukhulelwa emva kokufumana iziphumo ezingezizo, kungangcono ukuba impilo kamama isebenzise eso sigqibo kwangethuba kunokulinda iziphumo ze-amniocentesis zifike emva koko zenzeke kamva.
Ngaba kukho naziphi na iingozi ezibandakanyekayo kolu vavanyo?
Ewe, njengakuyo nayiphi na uvavanyo lwezonyango, kukho iingozi ezithile. Ngenxa yokuba olu vavanyo lwenziwa kwasekuqaleni kokukhulelwa, umngcipheko wokuphuphuma kwesisu unokuba phezulu kancinci kunakwi-amniocentesis. Kukwakho nomngcipheko wosulelo.
Kwiimeko ezingaqhelekanga kakhulu, ingakumbi ukuba olu vavanyo lwenziwe ngaphambi kweeveki ezili-9, kuye kwakho iingxelo zeziphene kwiminwe yomntwana. Ngenxa yesi sizathu, olu vavanyo alusoloko lwenziwa de kube ziiveki ezili-10 .
Eyona nto ibalulekileyo kukuba ugqirha wakho akuxelele ngaphambi kokuba wenze olu vavanyo.Kubalulekile ukuthetha nogqirha wakho ngale mingcipheko. Ingakumbi ukuba uzala amawele, qiniseka ukuba olu vavanyo lwenziwa ngugqirha onamava kolu vavanyo.
Ngubani ocetyiswa uvavanyo lweCVS?
Oogqirha ngokubanzi bacebisa ukuba oomama abanezi zinto zilandelayo zomngcipheko baqwalasele olu vavanyo:
- Oomama abaneminyaka engama-35 nangaphezulu (umngcipheko wokuba nomntwana onesiphene se-chromosome esifana ne-Down syndrome uyanda njengoko iminyaka ikhula).
- Izibini ezisele zinomntwana onesiphene sokuzalwa okanye ezinembali yentsapho eneso simo.
- Ukuba omnye wabazali unesifo esaziwayo sokungaqheleki kwe-chromosome okanye isifo semfuza.
- Oomama abafumene iziphumo ezingaqhelekanga kwezinye iimvavanyo zemfuza ezenziwe ngexesha lokukhulelwa.
Ugqirha wakho angakunika icebiso elifanelekileyo lokuba olu vavanyo lukulungele na. Kodwa ekugqibeleni, isigqibo sokwenza olu vavanyo okanye ukungaluthathi kufuneka senziwe nguwe kunye neqabane lakho, emva kwengxoxo enzulu nogqirha wakho.
Uvavanyo lweCVS lwenziwa njani?
Ngaphambi kokuba wenze olu vavanyo, wena neqabane lakho niza kuthunyelwa kwingcebiso yemfuza, apho iingenelo, iingxaki kunye neengozi zolu vavanyo ziya kucaciswa ngokucacileyo kuni.
Emva koko kwenziwa i-ultrasound scan ukujonga ubudala bokukhulelwa komntwana kunye nendawo echanekileyo ekuyo i-placenta. Uvavanyo lwenziwa kamva, ngesiqhelo phakathi kweeveki ezili-10 ukuya kwezili-12 emva kokuba ugqibile ukuya exesheni.
Kukho iindlela ezimbini eziphambili zokufumana isampuli yeseli kwi-placenta.
Ngesitho sangasese sowesifazane (indlela ye-Transvaginal)
Kule meko, kufakwa isixhobo esibizwa ngokuba yi-speculum kwilungu lobufazi, ngendlela efana novavanyo lwe-Pap. Emva koko, kufakwa ityhubhu yeplastiki ebhityileyo kakhulu ngelungu lobufazi ize inyuke nomlomo wesibeleko. Phantsi kwesikhokelo se-ultrasound scan, le tyhubhu ikhokelwa kwi-placenta, apho kuthathwa khona isampuli encinci yeeseli.
Ngesisu (indlela ye-Transabdominal)
Ngale ndlela, efana novavanyo lwe-amniocentesis, kufakwa inaliti encinci kakhulu esiswini ize idluliselwe kwi-placenta. Emva koko kuthathwa isampuli yeeseli apho.
Isampulu yeseli efunyenwe ngale ndlela ithunyelwa kwilebhu. Apho, iiseli zikhuliswa kulwelo olukhethekileyo kwaye zivavanywe kwiintsuku ezimbalwa. Iziphumo ezipheleleyo zingafunyanwa kwiiveki ezi-2. Ugqirha wakho uza kukwazisa ngeziphumo.
Ngaba olu luvavanyo olubuhlungu?
Usenokuva iintlungu ezithile, kodwa ziya kudlula ngokukhawuleza . Lonke uvavanyo luza kuthatha ubuninzi bemizuzu engama-30 ukususela ekuqaleni ukuya ekupheleni. Kuthatha imizuzu embalwa kuphela ukuqokelela isampuli.
Kwenzeka ntoni emva kovavanyo?
Kuya kufuneka uphumle okwethutyana emva kovavanyo. Ngoko ke licebo elihle ukuza nomntu ekhaya. Ufanele uphumle imini yonke. Uhlala ucetyiswa ukuba ungathwali izinto ezisindayo, uzilolonge, kwaye ulale ngesondo kangangeentsuku ezi-3.
Usenokuba nokuqaqamba nokuphuma kwegazi kancinci, nto leyo eqhelekileyo. Kodwa yazisa ugqirha wakho ngayo. Okubaluleke kakhulu, ukuba ubona naluphi na ulwelo oluphuma kwilungu lobufazi, xelela ugqirha wakho ngoko nangoko.
Umyalezo Wokuya Ekhaya
- I-CVS luvavanyo oluchanekileyo kakhulu olunokufumanisa iimeko zemfuza kumntwana kwasekuqaleni kokukhulelwa.
- Oku kuneengenelo (ukufumana iziphumo kwangethuba) kunye neengozi ezincinci (amathuba amancinci kakhulu okuphuphuma kwesisu kunye nosulelo).
- Olu vavanyo alufanele wonke umntu. Ludla ngokucetyiswa kwabo banezinto ezithile ezinokuba yingozi, njengokuba ngaphezulu kweminyaka engama-35 ubudala.
- Ukuba olu vavanyo luza kwenziwa okanye aluzanywanga sisigqibo somntu ngamnye phakathi kwakho neqabane lakho. Thetha nogqirha wakho ngononophelo kwaye ufumane lonke ulwazi ngaphambi kokuba wenze eso sigqibo.
- Landela yonke eminye imiyalelo enikiweyo emva kovavanyo ngokuchanekileyo. Ukuba ufumana naziphi na iimpawu ezingaqhelekanga, yazisa ugqirha wakho ngoko nangoko.
