ʻO ka placenta calcium a iʻole ka helu nuiʻana o ka placenta i ka 80% o nā hihia me kahi'ōpilikia o ka'ōpū. Ma kēiaʻano, i loko o ka hana lapaʻau, ua hoʻolālā ka manaʻo inā inā he mau kikowaena ma ka placenta , he hōʻailona kēia echographic o ka lawaʻole o ka muteroplacental a iʻoleʻole.
Eia naʻe,ʻo nā haʻawina e hōʻike ana ma kekahi mauʻano,ʻo ka placenta me nā kiko'īʻaʻole ia he hōʻailona o nā meaʻinoʻole i ka uluʻana o ke keiki, e like me ka ulu nui a me ka cardiomotor. ʻO ka hopena o ke kaloka ma ka placenta he hopena ia o ka hopena o nā moku kūpono i ka gestosis, ka maʻi, ka necrosis kūlohelohe o ka'ōpū i ke kaʻina o kaʻelemakule, ka hoʻopaʻaʻana i ka'ōpū a me ka mea nui i kaʻai.
No ka'ōleloʻana,ʻaʻole lawa ka lawaʻana o ka hānaiʻana ma ka heluʻana i loko o ka'ōpū, hiki i ka hōʻoiaʻana o kēia mea me nā meaʻokoʻa'ē aʻe e hōʻoiaʻiʻo i ka maʻi o ka'ōpiopio. Ināʻole, ua heluʻia ka heluʻana o ka placenta i mea kūpono no ka hoʻohaʻahaʻaʻana i nā hana o ka placenta.
He aha keʻano o ka hōʻeaʻana o ka placenta a me keʻano o ka pilikia?
ʻO ka'ōpiopio kahiko o ka placenta kahi hanaʻole ma waena o ke kiʻekiʻe o ka hoʻomauʻana o ka placenta a me ka manawa o ka hāpaiʻana. Hiki keʻikeʻia e ka ultrasound, kahi e heluʻia ai ka mānoanoa o ka placenta , ka nui, i kaʻikeʻana o nā hanana likeʻole, e like me nā kālepa.
