Kusukela emavikini angu-12 kuya ku-40 kuqala isikhathi sokubeletha kwengane ezayo. Ngalesi sikhathi, zonke izinhlelo zesitho azikahle zisebenze. Iviki lesi-13 yisikhathi sokusabela kwe-motor fetus. Ukhathazekile, ukuphefumula, i-endocrine, amasosha we-fetus aqhubeka nokwenza ngenkuthalo. Izici zengane yakho yesikhathi esizayo ziba ngaphezulu kakhulu. Isonto le-13 lokukhulelwa yisikhathi sokuqala sokusabela ngokomzwelo kwengane ezayo.
Ukuthuthukiswa kwe-Fetal emavikini angu-12-13
Ukuhlola ukuthuthukiswa nokuxilongwa kwe-fetal pathology, i-fetometry ye-fetus yenziwa ngamasonto angu-12 noma angu-13.
Amapharamitha we-fetometry kanye nesimiso sabo emntwaneni wesonto le-13 lokukhulelwa:
- usayizi we- biparietal fetal - 24 mm;
- ubude bethanga - 12 mm;
- isifuba sesifuba - 24 mm.
Emasontweni angu-13, umbungu unesisindo samagremu angu-31, ubude buka-10 cm.
I-TVP emavikini angu-13
Ubuningi bekholomu noma i-TVP yiparamitha odokotela abakwazisa ngesikhathi sokuhlolwa kwe-ultrasound ngeviki le-13 lokukhulelwa. Ubuningi besikhala sekhasi ukuqoqwa kohlobo olusemuva kwenduku yentombazane. Incazelo yale parameter ibalulekile ekuxilongweni kwezinto ezingezansi zofuzo zokuthuthukiswa komntwana, ikakhulukazi ekuchazeni i-Down syndrome, i-Edwards, i-Patau.
I-TVP emavikini angu-13 yinto evamile
Inani elivamile lokuphila ngokomzimba lobukhulu besikhala se-collar isikhala esingu-2.8 mm ngesonto 13. Inani elincane lemanzi liyisici sabo bonke abantwana. Ukwanda kwesikhala somklamo wezingaphezu kuka-3 mm kubonisa ukuthi kungenzeka ukuthi kukhona i-Down's syndrome enganeni ezayo. Ukuze kuqinisekiswe ukuthi kutholakala yini, kudingekile ukuba uhlole izivivinyo ezingenayo, okungaba yingozi enganeni. Ingozi yokuthuthukisa lesi sifo ngesikhathi sokukhulelwa kokuqala emva kweminyaka engama-35 yanda kakhulu.
Khumbula ukuthi ukuxilongwa kokuqina okwenyuka kwesikhala sekhanda akusho ukuthi kube khona ukutholakala kwe- genetic pathology , kodwa kuvumela kuphela ukucacisa iqembu eliyingozi phakathi kwabesifazane abakhulelwe.
