I ka pehea a pehea pehea e ana aiʻo TWP?
Hoʻopaʻaʻia kēia noi i loko o 11-13 mau wiki. Hōʻikeʻia kēia ma kaʻikeʻana ma hope o nā hebedoma 14 e hoʻopili pololeiʻia ka wai o ka wai e loaʻa ana i ka lymphatic pūnaewele e ulu ana ma ka'ōpū o ka'ōpū.
Ma hope o ke anaʻana i ka nui o ka coccygeal-parietal, hoʻohana ke kauka i ka unuhi transraser ultrasound eʻike ai i nā koina TVP o ka hānal, ka mea likeʻole i nā hebedoma o ka'ōpū, a hoʻohālikelike i nā kumu i loaʻa me ka papa. I ka manawa like, ua hoʻonohonohoʻia ka wai o ke kinikoki i keʻano o kahiʻeleʻele i ka nānā o ka mea, a me kaʻili - i keʻokeʻo.
Pehea e hoʻonuiʻia ai nā hopena o ke ana?
Hoʻolālāʻia nā kūlana o ka TVP no nā hebedoma, a hōʻikeʻia ma kahi papaʻaina. No laila, ma 11 mau hebedoma,ʻaʻole eʻoi aku ka nui o ka mānoanoa o kēia'āpana i 1-2 mm, a i ka manawa he 13 mau wiki - 2.8 mm. I kēia hihia,ʻo ka piʻiʻana o ka waiwai o kēia māhele e kū pololei ma kahi kūlike i ka uluʻana o ka'ōpū.
ʻO ka hoʻonuiʻana i kēia hōʻailonaʻaʻole i ka hōʻike mau i ka heleʻana o nā pathology. No laila, e like me nāʻikepili, 9 out of 10 children, nona ka TVP 2.5-3.5 mm, ua hānauʻia me nā pilikia kinoʻole. No laila,ʻo ka loiloiʻana i nā hopena e pono ke mālamaʻia e nā kauka wale nō, a me ka hoʻohālikelikeʻana i nā waiwai me nā'ōwili, e nānā i nāʻano o kēlā me kēia keiki. Ma ka hihiaʻole e ho'āʻo ka makuahine i ka manawa e wehe i nā hualoaʻa ma keʻano hoʻokahi.
Eia naʻe,ʻo ke kiʻekiʻe o ka helu o kēia māhele,ʻo kaʻoi aʻe o ka mea e loaʻa ai i nā pēpē kromosomal. Kekahi laʻana, me ka TVP like i 6 mm, hiki ke'ōlelo me ka maopopo e hānauʻia ka pēpē ma muli o ka hāpaiʻana i kēia wā i ka hanaʻana ma nā mea hana kino. ʻAʻole kēia he kūponoʻole ma lalo o ka maʻi.
Pēlā,ʻo TWP, ka mea loli i nā hebedoma o ka'ōpū a nānāʻia ma kahi papaʻaina, e pili ana i kēlā mau hōʻailona eʻae i ka hōʻailona mua o nā maʻi o ka hānai intrauterine.
