Ngaba uyafuna ukwazi ngolu vavanyo lubalulekileyo ngaphambi kokuba ube nomntwana? (Isampuli yeChorionic Villus - CVS) Masithethe ngeenkcukacha!

Molo! Umele ukuba ucinga ngomntwana omlindeleyo kule mihla, akunjalo? Ngoko ke, ngamanye amaxesha oogqirha bathetha ngeemvavanyo ezahlukeneyo ukuze bafumane impilo yeentsana kwangaphambili. Olunye uvavanyo olukhethekileyo yi -`(Chorionic Villus Sampling)` , esilubiza ngokuba yi -`(CVS)` ngamafutshane. Nangona oku kuyinkimbinkimbi kancinci, masiqonde ngokulula? Olu lwazi lubaluleke kakhulu koomama abaninzi.

Masiqale sibone ukuba yintoni olu vavanyo lwe-`(CVS)`?

Ngamafutshane, xa umntwana wakho esesibelekweni, uyazi ukuba umntwana ufumana izondlo zakhe kwinxalenye ebizwa ngokuba yi-placenta . Olu luvavanyo oluthatha iiseli ezimbalwa ezincinci kuloo placenta. Into emangalisayo kukuba, ezi seli ezivela kwi-placenta kunye neeseli zomntwana wakho ziyafana ngokwemfuza . Oko kuthetha ukuba singafunda ngeeseli zomntwana ngokuhlola iiseli ezivela kwi-placenta. Ayilobuchwepheshe obuphambili na obo?

Olu vavanyo lujonga ikakhulu ukuba umntwana akanazo naziphi na iingxaki ze-chromosome . Umzekelo, iimeko ezifana ne- "Down syndrome" . Oku kudla ngokwenziwa phakathi kweeveki ezili-10 ukuya kwezili-13 zokukhulelwa. Oko kukuthi, kwiinyanga ezintathu zokuqala zokukhulelwa.

Enye into ebalulekileyo kukuba olu vavanyo `(CVS)` alulo `uvavanyo lokuxilonga` , kodwa `luvavanyo lokuhlola`. Oko kukuthi, olu vavanyo lunokubonisa ngokuthe ngqo ukuba kunokwenzeka kangakanani ukuba umntwana azalwe ene -chromosome disorder ethile. Ke ngoko, olu luvavanyo oluxabisekileyo kakhulu.

Kutheni ke, olu vavanyo lwe-`(CVS)` lwenziwa? Lubaluleke kubani?

Oogqirha baxelela bonke abafazi abakhulelweyo ngolu vavanyo. Nangona kunjalo, lunokuba lubaluleke ngakumbi kwabanye abantu. Oko kukuthi, koomama abanomngcipheko omkhulu wokuba abantwana babo babe nokukhubazeka kwe-chromosome. Ngubani owela kweli qela linobungozi obukhulu? Makhe sijonge:

• Oomama abakhulelweyo abadala (ingakumbi abo baneminyaka engaphezu kwama-35 ubudala ).
• Oomama abasele benomntwana onesifo se-chromosome .
• Abo babonakalise ingxaki ngovavanyo lokuhlolwa lwangaphambili.
• Ukuba kukho umntu kusapho lwakho okanye kusapho lweqabane lakho onembali yeengxaki zemfuza .

I-CVS ikwathathwa njengenye indlela yokuvavanya i-amniocentesis , olunye uvavanyo, kuba i-CVS inokwenziwa kwangethuba kakhulu xa ukhulelwe, nto leyo enika abazali ixesha elingakumbi lokufumana iingcebiso abazifunayo nokwenza izigqibo abafanele bazenze.

Kodwa kukho enye into ekufuneka uyikhumbule apha. Ngokungafaniyo ne-amniocentesis, i-CVS ayiboneleli ngolwazi malunga neziphene ze-neural tube, ezifana ne -spina bifida . Kukwakho noluvo lokuba i-CVS ineengozi ezingaphezulu kancinci kune-amniocentesis. Ngoko ke, ngaphambi kokuba uthathe isigqibo sokuba uza kwenza olu vavanyo okanye hayi, kufuneka uhlolisise ngononophelo izinto ezilungileyo nezingalunganga. Thetha nogqirha wakho ngale nto, kulungile?

Ngoko ke, ngaba ngokwenene kufuneka ndenze olu vavanyo lwe-`(CVS)`?

Nasi isizathu. Kwiimeko ezininzi, olu vavanyo alufuneki kubafazi abakhulelweyo abangekho semngciphekweni omkhulu . Nangona kunjalo, ugqirha wakho unokucebisa ukuba wenze olu vavanyo, ingakumbi kwezi meko zilandelayo:

• Ukuba uneminyaka engama-35 ubudala nangaphezulu .
• Ukuba kukho umntu kusapho lwakho (okanye kusapho lweqabane lakho) oneengxaki zofuzo , okanye ukuba kukho imbali yeengxaki ezinjalo.
• Ukuba sele unomntwana onesifo semfuza , okanye ukuba umntwana wayeneengxaki ze-chromosome ekukhulelweni kwangaphambili.
• Ukuba ukhe wakrokrela ukuba kusenokuba kukho ingxaki ngovavanyo lokuhlola lwangaphambili.

Into ebalulekileyo kukuba akufuneki uzikhethele ngokwakho ukuba uza kulwenza na olu vavanyo okanye hayi. Kubalulekile ukuthetha nogqirha wakho ngalo uze ugqibe ukuba yintoni ekulungeleyo. Baza kukuchazela yonke into.

Kulungile, ngoku masibone ukuba olu vavanyo lwe-`(CVS)` lwenziwa njani kanye kanye.

Okokuqala, masiqonde ezinye zezona ndawo zibalulekileyo zolu vavanyo lwe-`(CVS)`. Uyazi, i-placenta yinxalenye yomzimba enika umntwana ukutya okuvela kumama, ngentambo yesisu . Kule placenta, kukho izinto ezincinci kakhulu ezifana neminwe ezibizwa ngokuba yi -`chorionic villi` . Ezi zezona zibalulekileyo kuthi. Kuba, iiseli ezikwezi `chorionic villi` ziqulathe ii-chromosomes ezifanayo kunye nokwakheka kwemfuza njengeeseli zomntwana wakho. Ayimangalisi loo nto?

Ngoko ke, okwenziwayo kuvavanyo lwe-`(CVS)` kukuthatha isampuli yeeseli kwi-`chorionic villi`. Emva koko, ezo seli ziyavavanywa kwi-`laboratory` ukuze kubonwe ukuba kukho naziphi na iingxaki ze-chromosome ezifana ne-`(Down syndrome)` okanye ezinye iimeko zemfuza ezifana ne -`(Tay-Sachs disease)` okanye `(fragile X syndrome)` .

Kukho iindlela ezimbini eziphambili zokwenza olu vavanyo.Nantsi lapho:

1. Indlela ye-Transcervical

Oku kuquka ukudlulisa umbhobho omncinci kakhulu ngaphakathi kwilungu lobufazi lakho uze ungene kwisibeleko sakho , ukhokelwa yi -ultrasound scan . Emva koko, kuthathwa isampuli yethishu kwi-chorionic villus kusetyenziswa ukufunxa okuthambileyo. Oku kunokuvakala ngathi yi-Pap smear kwabanye abantu, kodwa kungekhona kubo bonke abantu.

2. Indlela ye-Transabdominal

Kule ndlela, ugqirha ufaka inaliti encinci eludongeni lwesisu sakho . Oku kwenziwa phantsi kwesikhokelo se-ultrasound scan, ukuze kufunyanwe indawo efanelekileyo. Inaliti isetyenziselwa ukufumana isampuli ye-chorionic villus. Le ndlela ikwaphumelela kwiimeko ezininzi.

Uza kuziva njani xa ubhala uvavanyo?

Kwabanye oomama, uvavanyo lwe-CVS alunazintlungu . Kwabanye, uvavanyo lusenokuvakala ngathi luneentlungu ezincinci okanye lubuhlungu emqolo ngexesha lokuqokelela iisampulu, ngendlela efanayo nexesha lokuya exesheni . Luyahluka kumntu nomntu. Ngokuqhelekileyo alunazintlungu.

Emva kokuthatha isampulu, ugqirha angajonga nokubetha kwentliziyo yomntwana. Uya kucetyiswa ukuba uphumle kakuhle iiyure ezimbalwa emva kovavanyo. Akulunganga ukutsala nzima kakhulu, kufuneka ulumke kancinci.

Ngaba kukho naziphi na iingozi ezibandakanyekayo kolu vavanyo lwe-`(CVS)`?

Ewe, njengalo naluphi na uvavanyo lwezonyango, kukho iingozi ezincinci ezibandakanyekayo kolu vavanyo lwe-`(CVS)`. Kubalulekile ukuzazi ezi zinto. Akukho nto inokubangela ukukhathazeka ngazo, ezi azenzeki rhoqo.

• Umngcipheko wokuphuma kwesisu : Le yinkxalabo abantu abaninzi abanayo. Umngcipheko wokuphuma kwesisu ngenxa yovavanyo lwe-CVS uphantsi kakhulu, ngesiqhelo malunga ne-1% (mhlawumbi ungaphantsi) . Nangona kunjalo, ezinye izifundo zibonisa ukuba lo mngcipheko unokuba phezulu kancinci ngendlela ye-transcervical ekhankanyiweyo ngaphambili.
• Usulelo: Oku kunqabile kakhulu, kodwa kunokwenzeka. Oogqirha balumkele kakhulu olu daba.
• Ukuchaphaza okanye ukopha : Unokufumana ukopha okuncinci emva kovavanyo. Oku kuqheleke ngakumbi kwindlela ye-transcervical. Oku kuya kuphela emva kosuku okanye ezimbini.
• Iziphene kwiminwe yomntwana: Oku kunqabile kakhulu . Kwakhona, kwasekuqaleni kakhulu ekukhulelweni (njengangaphambi kweeveki ezili-10)Olu vavanyo lolona hlobo lokunciphisa amathuba okuba oku kwenzeke. Yiyo loo nto lwenziwa ngexesha elifanelekileyo.

Musa ukoyika xa usiva ngezi ngozi, kulungile? Uninzi lwazo aluqhelekanga. Ugqirha wakho uza kuthetha nawe ngazo zonke ezi ngozi, akuchazele ukuba zeziphi iingozi zakho, kunye nendlela ongazinciphisa ngayo.

Uvavanyo lwe-CVS lwenziwa nini ngexesha lokukhulelwa?

Sele sithethe kancinci ngale nto ngaphambili, akunjalo? Uvavanyo lweChorionic Villus Sampling (CVS) ludla ngokwenziwa phakathi kweeveki ezili-10 ukuya kwezili-13 zokukhulelwa. Eli lithathwa njengelona xesha likhuselekileyo nelifanelekileyo lolu vavanyo. Ke ngoko, kubalulekile ukuba ulwenze ngexesha ugqirha wakho akuxelele ngalo.

Kuthatha ixesha elingakanani ukufumana iziphumo zovavanyo?

Oku kuyinto ebalulekileyo ekufuneka uyazi. Ixesha elithathwayo ukufumana iziphumo zovavanyo lwe-CVS linokwahluka kancinci ngokuxhomekeke kwimeko ethile evavanywayo . Ezinye iziphumo zingafunyanwa kwiiyure ezimbalwa . Ezinye zingathatha iintsuku ezimbini ukuya kwezintathu, okanye iveki . Ugqirha wakho uza kukwazisa oku kwangaphambili, ngoko ungakhathazeki.

Ngoko ke, zeziphi iingongoma eziphambili ekufuneka uzikhumbule kwinto esithethe ngayo? (Umyalezo Wokubuyela Ekhaya)

Kulungile, sithethe kakhulu ngolu vavanyo lwe-`(Chorionic Villus Sampling - CVS)`, akunjalo? Ngoku, makhe sikukhumbuze nje ngezinto ezibalulekileyo ekufuneka uzikhumbule.

• I-CVS luvavanyo olukhethekileyo olunokwenziwa kwangethuba ekukhulelweni (phakathi kweeveki ezili-10-13).
• Oku kujonga ikakhulu ukuba umntwana uneengxaki ze-chromosome ezifana ne-Down syndrome.
• Ngenxa yokuba olu luvavanyo lokuxilonga , iziphumo zichaneke kakhulu.
• Oku akufuneki kuye wonke umntu. Oogqirha bacebisa kuphela abo baneengxaki ezithile zomngcipheko (umz., abantu abaneminyaka engaphezu kwama-35, imbali yosapho yezifo zemfuza).
• Kukho iindlela ezimbini zokwenza uvavanyo (ngomlomo wesibeleko okanye ngesisu), zombini zenziwa ngoncedo lwe-ultrasound.
• Kunokubakho iingozi ezincinci kakhulu (umz., ithuba lokuphuphuma kwesisu eliyi-1%), kodwa iingxaki ezinkulu azixhaphakanga.
• Ngaphambi kokuba uthathe isigqibo sokuba uza kulwenza na olu vavanyo okanye hayi, kubalulekile ukuthetha nogqirha wakho kakuhle uze uqonde zonke izinto ezilungileyo nezingalunganga.

Ukuqukumbela, kulungile ukuba uzazi ezi mvavanyo, kodwa ungazizoyiki ngokungeyomfuneko. Ugqirha wakho nguye onokukunika icebiso elifanelekileyo malunga nokuba yintoni ekulungeleyo wena nomntwana wakho. Ngoko ke, thetha naye ngayo nayiphi na imibuzo okanye iinkxalabo onokuba nazo.

Ndiyathemba ukuba olu lwazi luza kukunceda. Ndinqwenela impilo entle wena nomntwana wakho ngamaxesha onke!
