Ukuba ungumama oza kuzala umntwana, ugqirha wakho mhlawumbi ukuxelele ngovavanyo olukhethekileyo olunokukuxelela okuninzi ngempilo yomntwana kwangaphambili. I-CVS lolunye uvavanyo olunjalo. Igama lisenokuvakala lisoyikisa kancinci, kodwa luvavanyo olubalulekileyo koomama abaninzi. Makhe sijonge ukuba yintoni, kutheni yenziwa, indlela eyenziwa ngayo, kwaye ingaba yinto yokoyika na.
Yintoni kanye kanye le CVS test?
Ngamafutshane, i-CVS (Chorionic Villus Sampling) luvavanyo olukhethekileyo olwenziwa ngexesha lokukhulelwa. Lusetyenziselwa ukujonga ukuba umntwana wakho ongekazalwa unezifo zofuzo okanye iziphene zokuzalwa. Ugqirha wakho uya kucebisa olu vavanyo kuphela ukuba kukho nakuphi na ukurhaneleka kokuba umntwana wakho uneziphene zofuzo okanye iziphene zokuzalwa.
Kodwa olu ayilovavanyo olunyanzelekileyo. Olu luvavanyo ekufuneka ulwenze ngokusekelwe kwiminqweno yakho. Yenza oku kuphela xa uvakalelwa kukuba kulungile kuwe emva kokuxoxa ngazo zonke izinto ezilungileyo, iingxaki kunye neengozi nogqirha wakho.
Olu vavanyo ludla ngokwenziwa phakathi kweeveki ezili-10 ukuya kwezili-13 zokukhulelwa. Enye inzuzo yolu vavanyo kukuba lunokuchonga ngokuchanekileyo isini somntwana (nokuba yintombazana okanye yinkwenkwe).
Ungenza njani uvavanyo?
Okwenzekayo koku kukuba isampuli encinci kakhulu yeeseli ithathwa kwi-placenta yomntwana wakho. Sibiza ezi seli ngokuthi `(Chorionic Villi)`. Ngoku usenokuba uzibuza ukuba kutheni isampuli ithathwa kwi-placenta kungekhona kumntwana. Cinga ngayo, umntwana wenziwe yiseli enye. Iindawo ze-placenta nazo zenziwe ngaloo maseli afanayo. Ke ngoko, ulwazi lwemfuza lomntwana lukwakwezi ndawo ze-placenta. Ngamanye amazwi, ezi seli zifana namawele ofuzo lomntwana. Ngoko ke le sampuli yeseli ithathwa ize ithunyelwe kwilebhu kwaye ihlalutywe ukuze kubonwe ukuba umntwana uneengxaki zemfuza.
Ngubani omele enze uvavanyo lweCVS?
Olu vavanyo lwe-CVS alulovavanyo oluqhelekileyo olufunyanwa ngabo bonke abafazi abakhulelweyo. Ugqirha wakho unokulucebisa ukuba unezinto ezithile ezinobungozi, okanye ukuba ukhe waphawula naziphi na iingxaki kwiskeni yangaphambili okanye kolunye uvavanyo.
Ugqirha wakho angakuxelela ngolu vavanyo kwiimeko ezilandelayo:
- Ukuba sele unomntwana onesifo esibangelwa lufuzo.
- Ukuba uneminyaka engaphezu kwama-35 ubudala (ngexesha lokukhulelwa). Umngcipheko wokufumana izifo ezithile zemfuza uyanda kancinci xa ukhula.
- Ukuba iziphumo zeskeni yangaphambili okanye olunye uvavanyo zibonise ukuba umntwana usemngciphekweni omkhulu wokuba nesifo semfuza.
- Ukuba wena, umyeni wakho, okanye nabani na kusapho lwakho unesifo okanye ukhe waba naso.
Into ebalulekileyo kukuba uthathe isigqibo sokuba uza kuvavanywa okanye hayi, nokuba unazo ezi zinto zinobungozi. Unelungelo lokungayiboni le nto.
Kwezinye iimeko, ugqirha wakho unokukucebisa ukuba ungalwenzi olu vavanyo. Ezi ziquka:
- Ukuba ukhe wopha igazi kwilungu lobufazi ngexesha lokukhulelwa.
- Ukuba unentsholongwane, ingakumbi isifo esidluliselwa ngesondo (STI).
Zeziphi izifo ezinokufunyaniswa ngolu vavanyo?
I-CVS ijonga kakhulu iingxaki ngee-chromosomes zomntwana. Ii-chromosomes zifana neepakethe ezincinci ezigcina ulwazi lwemfuza yomzimba wethu (i-DNA). Ukuba kukho utshintsho kwezi zinto, njengokwanda, ukuncipha, okanye ukuqhekeka kwe-chromosome, umntwana unokuba nesifo sokuzalwa.
Nazi ezinye zeemeko eziphambili ezinokufunyaniswa ngovavanyo lwe-CVS:
- I-Down syndrome (i-Down syndrome okanye i-trisomy 21): Le yeyona meko yemfuza ekuthethwa kakhulu ngayo phakathi kwethu.
- Icystic fibrosis
- Isifo seSickle cell
- Isifo sikaTay-Sachs
- I-Trisomy 18 (i-Trisomy 18 okanye i-Edward syndrome)
- I-Trisomy 13 (i-Trisomy 13 okanye i-Patau Syndrome)
Ngaba kukho izinto ezingenakubonwa luvavanyo lweCVS?
Ewe. Ayikwazi ukubona zonke iziphene zokuzalwa. Ayikwazi ukubona izinto ezifana neziphene zetyhubhu ye-neural (NTDs). Umzekelo, ayinakukwazi ukubona ingxaki ebizwa ngokuba yi-spina bifida. Kukho ezinye iimvavanyo ezifana ne-amniocentesis ezinokubona izinto ezinjalo.
Kwakhona, i-CVS ayinakukwazi ukubona iziphene zesakhiwo ezifana nomngxuma entliziyweni yomntwana okanye umlebe oqhekekileyo okanye intlama evulekileyo. Ezi zinokufunyanwa nge-anomaly scan, eyenziwa phakathi kweeveki ezili-18 nezingama-20 zokukhulelwa.
Kwenzeka ntoni ngaphambi nangexesha lovavanyo?
Ngaphambi kokuba ucwangcise uvavanyo lwakho, uza kudibana nomcebisi wezemfuza okanye ingcali yezemfuza. Baza kukuchazela iingenelo, iingozi, kunye nenkqubo yonke. Baza kukubuza nayiphi na imibuzo okanye iinkxalabo onokuba nazo. Baza kukwenza iskeni ukuze babone ukuba ukhulelwe iiveki ezingaphi. Usuku olufanelekileyo lovavanyo lwe-CVS luya kumiselwa ngokusekelwe kuloo nto.
Lwenziwa njani olu vavanyo? Ingaba lubuhlungu?
Olu vavanyo alubuhlungu kangako, kodwa ungaziva ungakhululekanga. Zimbini iindlela eziphambili zokwenza oku. Ugqirha wakho uya kukhetha eyona ndlela ilungileyo kuxhomekeke ekubeni iphi i-placenta yakho.
1. Ngesitho sangasese somfazi (iTranscervical):Kule nto, kufakwa isixhobo esibizwa ngokuba yi-speculum kwisini sakho, kwaye ityhubhu yeplastiki encinci kakhulu idluliselwa kuyo nge-cervix ukuya apho i-placenta ikhona. Konke oku kwenziwa phantsi kweliso le-scan. Emva koko, kuthathwa isampuli encinci yeeseli kwi-placenta ngaloo tyhubhu.
2. I-Transabdominal: Kule ndlela, kufakwa inaliti encinci kakhulu eluswini lwesisu sakho, ikhokelwa yi-scan, kwindawo apho i-placenta ikhoyo, kwaye kuthathwa isampuli yeseli. Ukuba wenza le ndlela, awuyi kuva ntlungu ingako kuba inani elincinci lamayeza lifakwa ukuze livale kuphela indawo apho inaliti ifakwe khona.
Nokuba yeyiphi na indlela, yonke le nkqubo ithatha ngaphantsi kwemizuzu engama-30.
Kwenzeka ntoni emva kovavanyo?
Uza kukwazi ukuya ekhaya emva nje kokuba uvavanyo lugqityiwe. Kungcono ukuphumla imini yonke. Uninzi lwabantu lunokubuyela kwimisebenzi eqhelekileyo ngosuku olulandelayo. Nangona kunjalo, ugqirha wakho uza kukuxelela ukuba uphephe imisebenzi efana nesondo, umthambo, kunye nokuphakamisa izinto ezisindayo iintsuku ezimbini ukuya kwezintathu.
Emva kovavanyo, usenokuba neentlungu zesisu ezincinci, ezifana nokuya kwakho exesheni. Usenokuba nokopha kancinci kakhulu kwilungu lobufazi. Oku kuqhelekile. Ukuba uvavanyo lwenziwe ngesisu, ungaziva ubuhlungu obuncinci apho inaliti ifakwe khona.
Zithini iingozi kunye neenzuzo zovavanyo lwe-CVS?
Njengakuvavanyo lwezonyango, kukho umngcipheko omncinci. Kodwa uphantsi kakhulu. Kufuneka senze isigqibo ngokusithelekisa neenzuzo.
| Iingozi | Iinzuzo |
|---|---|
| Ukuphuphuma kwesisu: Le yinto abantu abaninzi abayoyikayo. Nangona kunjalo, umngcipheko wokuphuphuma kwesisu ngenxa yovavanyo lwe-CVS ungaphantsi kwe-1%. Oko kuthetha ukuba bangaphantsi komnye kubantu abali-100 abaye baphuphuma. | Ukufumana iziphumo kwangethuba: Eyona nzuzo inkulu kukwazi imeko yomntwana kwangethuba ekukhulelweni, nto leyo ekunika ixesha elingakumbi lokwenza izigqibo nokulungiselela ikamva ngengqondo. |
| Usulelo: Njengakwezinye iinkqubo zonyango, kukho umngcipheko omncinci kakhulu wosulelo. | Ukuchaneka okuphezulu:Olu vavanyo luchaneke nge-99%, ngoko ke ungaqiniseka ngokupheleleyo ngeziphumo. |
| Ukukhubazeka kwamalungu omzimba: Akwenzeki rhoqo, ingakumbi ukuba olu vavanyo lwenziwa ngaphambi kweeveki ezili-10, kubekho iingxelo zokuba umntwana usenokuba nesiphene kwenye yeengalo okanye imilenze yakhe. Yiyo loo nto kwenziwa ngexesha elifanelekileyo. | Ixesha lokulungiselela: Ukuba iziphumo zibonisa ukuba umntwana uza kufuna naluphi na unyango olukhethekileyo emva kokuzalwa, oku kuya kukunceda ulungiselele ezo zinto kwangaphambili kwaye wazise isibhedlele. |
| Ezinye iingozi ezincinci: Kukho iingozi ezincinci kakhulu ezifana nokopha kakhulu, ukuvuza kolwelo lwe-amniotic olujikeleze usana, kunye nokwanda kwe-Rh. | Intuthuzelo yengqondo: Xa kukho izinto ezinobungozi kwaye iziphumo zovavanyo zibuya zisithi zilungile, intuthuzelo yengqondo yokukwazi ukuchitha lonke ixesha lokukhulelwa ngolonwabo ngaphandle koloyiko okanye amathandabuzo ayinakuthelekiswa nanto. |
Kuthatha ixesha elingakanani ukuba iziphumo zibuye? Kuthekani ukuba iziphumo zilungile?
Emva kokuba isampuli yeseli ithunyelwe kwilebhu, iiseli ziyakhula kwaye zivavanywe. Ezinye iziphumo zokuqala ziyafumaneka kwiintsuku ezimbalwa. Nangona kunjalo, ezinye iimeko zithatha ixesha elide ukuvavanywa. Ngoko ke kungathatha iintsuku ezili-10 ukuya kwiiveki ezimbini ukufumana ingxelo epheleleyo. Ugqirha wakho okanye umcebisi wezemfuza uza kukufowunela ukuze akuxelele ngeziphumo.
Nangona uvavanyo lwe-CVS luchanekile ngama-99%, alunakuqikelela ubukhali bemeko. Kwiimeko ezimbalwa kakhulu, malunga ne-1%-2%, ukungaqhelekanga kunokuphelela kwi-placenta kwaye kungabi nampembelelo kumntwana.
Ukuba iziphumo ngelishwa ziqinisekisa ukuba umntwana wakho unesimo sofuzo, kuya kuba lixesha elinzima kakhulu kuwe. Ngelo xesha, ugqirha wakho kunye nomcebisi wakho baya kuthetha nawe ngokucacileyo ngesi sifo, indlela esiza kuyichaphazela ngayo ikamva lomntwana wakho, kunye neendlela onokukhetha kuzo.
