Isampuli se-chorionic villus

I-chorionic villus sampling (i-CVS) isivivinyo abanye besifazane abakhulelwe okufanele bahlole izingane zabo ngezinkinga zofuzo.

I-CVS ingenziwa ngomlomo wesibeletho (transcervical) noma ngesisu (transabdominal). Izinga lokukhulelwa kwesisu liphakeme kancane lapho ukuhlolwa kwenziwa ngomlomo wesibeletho.

Inqubo ye-transcervical yenziwa ngokufaka ishubhu elincanyana lepulasitiki ngesitho sangasese kanye nomlomo wesibeletho ukufinyelela kwi-placenta. Umhlinzeki wakho wezokunakekelwa kwempilo usebenzisa izithombe ze-ultrasound ukusiza ukuhola ithubhu iye endaweni enhle yokwenza izibonelo zalokho. Kususwa isampula elincane lezicubu ze-chorionic villus (placental).

Inqubo yokudlulela ngasesizalweni senziwa ngokufaka inaliti esiswini nasesizalweni nasemgodleni. I-Ultrasound isetshenziselwa ukusiza ukuhola inaliti, futhi inani elincane lezicubu lidonselwa kwisirinji.

Isampula lifakwa esitsheni futhi lihlolwe elebhu. Imiphumela yokuhlolwa ithatha cishe amaviki amabili.

Umhlinzeki wakho uzochaza inqubo, ubungozi bayo, nezinye izinqubo ezifana ne-amniocentesis.

Uzocelwa ukuthi usayine ifomu lokuvuma ngaphambi kwale nqubo. Ungacelwa ukuthi ugqoke ingubo yasesibhedlela.

Ukusa kwenqubo, ungacelwa ukuthi uphuze uketshezi futhi uyeke ukuchama. Ukwenza kanjalo kugcwalisa isinye sakho, okusiza umhlinzeki wakho abone ukuthi angaqondisa kuphi inaliti.

Tshela umhlinzeki wakho uma uxabana ne-iodine noma i-shellfish, noma uma unezinye izifo ezingezwani nomzimba.

I-ultrasound ayilimazi. Ijeli elicacile, elisuselwa emanzini lisetshenziswa esikhumbeni sakho ukusiza ngokudluliswa kwamagagasi omsindo. Iphenyo eliphethwe ngesandla elibizwa ngokuthi i-transducer bese lihanjiswa ngaphezu kwesisu sakho. Ngaphezu kwalokho, umhlinzeki wakho angafaka ingcindezi esiswini sakho ukuthola isikhundla sesibeletho sakho.

Ijeli lizozizwa libanda ekuqaleni futhi lingacasula isikhumba sakho uma lingagezwanga ngemuva kwenqubo.

Abanye besifazane bathi indlela yesitho sangasese sowesifazane izwa njengokuhlolwa kwePap ngokungakhululeki okuthile kanye nomuzwa wengcindezi. Kungaba nenani elincane lokopha kwesitho sangasese sowesifazane ngokulandela inqubo.

Udokotela obelethayo angenza le nqubo cishe imizuzu emihlanu, ngemuva kokulungiselela.

Isivivinyo sisetshenziselwa ukukhomba noma yisiphi isifo sofuzo enganeni yakho engakazalwa. Inembile kakhulu, futhi ingenziwa ekuqaleni kokukhulelwa.

Izinkinga zofuzo zingenzeka kunoma yikuphi ukukhulelwa. Kodwa-ke, lezi zinto ezilandelayo zandisa ubungozi:

• Umama osekhulile
• Ukukhulelwa kwangaphambilini ngezinkinga zofuzo
• Umlando womndeni wokuphazamiseka kofuzo

Ukwelulekwa ngofuzo kunconywa ngaphambi kwenqubo. Lokhu kuzokuvumela ukuthi wenze isinqumo esingaphuthumi, esinolwazi mayelana nezinketho zokuxilongwa kokubeletha.

I-CVS ingenziwa ngokushesha ekukhulelweni kune-amniocentesis, imvamisa cishe emasontweni ayishumi kuye kwayi-12.

I-CVS ayitholi:

• Iziphambeko ze-Neural tube (lokhu kufaka ikholomu yomgogodla noma ubuchopho)
• Ukungahambelani kwe-Rh (lokhu kwenzeka lapho owesifazane okhulelwe enegazi elingelona i-Rh nengane yakhe engakazalwa inegazi eline-Rh)
• Izinkinga zokuzalwa
• Izinkinga ezihlobene nokusebenza kobuchopho, njenge-autism nokukhubazeka kwengqondo
  
  

Umphumela ojwayelekile usho ukuthi azikho izimpawu zokukhubazeka kofuzo enganeni ekhulayo. Noma imiphumela yokuhlolwa inembe kakhulu, akukho ukuhlolwa okunemba ngo-100% ekuhloleni izinkinga zofuzo ekukhulelweni.

Lokhu kuhlolwa kungasiza ekutholeni amakhulukhulu ezinkinga zofuzo. Imiphumela engajwayelekile ingahle ibangelwe yizimo zofuzo ezahlukahlukene, kufaka phakathi:

• I-Down syndrome
• Ama-hemoglobinopathies
• Isifo se-Tay-Sachs

Khuluma nomhlinzeki wakho mayelana nencazelo yemiphumela yakho ethile yokuhlolwa. Buza umhlinzeki wakho:

• Isimo noma ukukhubazeka kungaphathwa kanjani phakathi noma ngemuva kokukhulelwa
• Yiziphi izidingo ezikhethekile ingane yakho engaba nazo ngemuva kokuzalwa
• Yikuphi okunye ongakhetha kukho mayelana nokugcina noma ukuqeda ukukhulelwa kwakho

Izingozi ze-CVS ziphakeme nje kancane kunalezo ze-amniocentesis.

Izinkinga ezingaba khona zifaka:

• Ukopha
• Ukutheleleka
• Ukuphuphuma kwesisu (kuze kufike kwabesifazane kwabangu-100)
• Ukungahambelani kwe-Rh kumama
• Ukuqhekeka kolwelwesi okungaholela ekuphuphumeni kwesisu

Uma igazi lakho lingenalo i-Rh, ungathola umuthi obizwa nge-Rho (D) immune globulin (RhoGAM neminye imikhiqizo) ukuvimbela ukungahambisani kwe-Rh.

Uzothola i-ultrasound yokulandelela ezinsukwini ezimbili kuya kwezi-4 ngemuva kwenqubo yokuqinisekisa ukuthi ukukhulelwa kwakho kuqhubeka ngendlela ejwayelekile.
