Ukukhenkcelela i-Down Syndrome, ukungavumelekanga kwentliziyo kunye nezinye izimo eziphene. Olu vavanyo okanye uvavanyo olufanayo lufanele lunikezwe kuwo wonke unina ekunakekeleni kokubeleka, oku akukona nje koomama abangaphezu kweminyaka engama-35, nangona banengxaki eyongeziweyo yowana ozalwa nge-Down Syndrome okanye ezinye iingxaki zobomi. Khumbula, ukuhlolwa kweso sixilongo, kodwa iskrini esilungileyo sithetha ukuba kunokwenzeka ukuba umntwana ochaphazelekayo uphepha.
Uvavanyo luyenziwe njani
I-ultrasound yenziwa phakathi kweiveki 11-14 ukulinganisa indawo eguquguqukileyo kwesikhumba emva kwentamo yomntwana wakho, eyaziwa njengeliphulo le-nuchal. Oku kufana ne-ultrasound rhoqo kumama.
Xa uvavanyo luyenziwe
Ngokuqhelekileyo phakathi kweeveki ezili-11 ukuya kwe-14 (ukusukela kwi-LMP). Ukwenza ngaphandle kwalolu hlobo kwenza uvavanyo luchaneke. Kukho uphando olwenziwayo ukusetha iirejista zokubhekisela ubukhulu benkongolo ye-nuchal kwenye i-ageesthood age.
Indlela Igalelo linikwe ngayo
Ngokuqhelekileyo njengento emihle okanye engalunganga, malunga ne-5% yezinga elifanelekileyo lobuxoki. Iskrini esikhombisayo sibonisa ukuba kukho amathuba aphezulu kunokuba isifo sakho sine-Down Syndrome. Wonke umntu unomngcipheko wokuba nomntwana nge-Down Syndrome, ngoko isikrini esingenanto asikho into efanayo neyilwayo ecocekileyo yempilo. Oku kuyamangalisa xa unina unesicatshulwa esibi kodwa umntwana ozalwa nge-Down Syndrome uzalwa.
Iingozi ezibandakanyekayo
Akukho mngcipheko kuvavanyo ngokwalo.
Nangona kunzima ukuqonda iziphumo. Olu luhlolo lokuhlola, olusetyenziswa ukukunceda uqonde umngcipheko weengxaki zezofuzo ngokukhulelwa kwakho. Ngoko ufika ekukhuleleni kwakho kunye nenani elithile lomngcipheko we-Down Syndrome. Olu vavanyo lokuphonononga lunokutshintsha uvavanyo lwengozi. Ngokomzekelo, nge-35 ndinomngcipheko we-1 ngowama-270 wokuba nosana olune-Down Syndrome.
Ukuba i-nuchal yokutshintshana kwenyanga ibonisa ukulinganisa ubukhulu bendawo, umngcipheko uyafana. Ukuba i-fold iyancipha umngcipheko wam, kodwa xa kunomngcipheko mngcipheko usenokunyuka. Le yilapho isiphakamiso sokwenza uvavanyo oluthe xaxa lwangena khona.
Ezinye iindlela
Ukuba uvavanyo lukhangelekile okanye ukuba ufuna nje ukwazi ngokucacileyo, kukho iimvavanyo ezikhoyo. Ungasebenzisa iimvavanyo ezingenayo i-amniocentesis okanye i-chorionic sampling (CVS), kodwa ezi zinto zenzele ingozi yokukhulelwa, nangona zichanekileyo kwaye zivavanyo lokuhlola kunokuhlola. Ezinye zezi zinto zingenziwa ekuqaleni kokukhulelwa ukuba ukuhlolwa kwe-nuchal yokunyanga.
Uvela Kuphi?
Ukuba i-nuchal ifowuni yokuhlola i-translucency i-positive, ungacetyiswa ukuba uqhube uvavanyo olunzulu olunjenge-amniocentesis okanye i-chorionic villus sampling (CVS). Oku kuphelele kuwe. Kukho i-ultrasound engakumbi enokuthi yenziwe kamva ekwacatshangelwa ukuba ihlolwe, kodwa ayinakuncipha kwaye ayithwali imingcipheko yokuvavanya.
