Chinhu choga choga chemutambo wembilical kazhinji, uye huwandu hunowedzera zvakanyanya kana mukadzi ane mimba yakawanda kana chirwere cheshuga. Sezvo mutemo, kupera kwemubilical arteri, uye ichi ndiro zita rezvakaitika zvakadaro, hazviiti dambudziko rakanyanya kumwana, asi richiri kunoda kuongororwa kwakawedzerwa uye nguva dzose kuongororwa.
Syndrome yeropa chete remutsara wembilical
Mutsara wechipfuva ndiwo hukama hukuru pakati pemwana naamai. Kazhinji musimboti wembilical une mitsetse 2 uye imwe mutezo. Kuburikidza nemuviri mwana anogamuchira oksijeni, zvibereko uye zvakakosha zvezvinhu, uye kuburikidza nemariti inobvisa zvinodhaka. Mune zvimwe zviitiko, pane zvisiri izvo, umo mune ariti imwe chete muumbilical cord. Ichi chinoshamisa chinonzi chirwere cheharia imwe chete kana aplasia.
Kana kubhakwa kwembilical arteri ndiyo chete chirwere, saka hapana ngozi kune mwana. Ichokwadi kuti mutoro unowedzera zvakanyanya, asi, semutemo, kunyange arteri imwe inobata nemabasa ayo.
Zvakakosha kuziva kuti chirwere chakadaro chinogona kutaura pamusoro pechromosomal zvisiri izvo kana kukonzera kusagadzikana kwemwoyo, nhengo dzepachivi, mafungiro nemapapu mumwana. Iyo chete arteri yomudonzvo wembilical inogona kuva yekutanga kana kuwanikwa - apo iyo yechipiri mudziyo, asi pane chimwe chikonzero chakamira kusimba nekuzadzisa mabasa ayo. Chero mamiriro ezvinhu, kana kushaya kwakafanana kwakaonekwa, kunyatsoongorora kunodiwa kuti uone zvimwe zvakaipa, pamwe nekuchengetedza nguva dzose kwechiremba.
Kuongororwa kwetambo imwechete yemudambo
Sarudzai kusakanganisika kunogona kunge sekutanga kwemavhiki makumi maviri ekuberekwa ne ultrasound mumuchinjikwa chikamu. Panguva imwecheteyo, kana pasina zvimwe zvinetso, ipapo mutezo wembilical, kunyange neyeri imwe chete, inobata nebasa rayo, kuchengeta ropa riri kufamba mumamiriro ezvinhu.
Chero mamiriro ose ezvinhu, apo chirwere chemusiti umwechete wemamiti chinowanikwa, kunyatsoongorora kwe fetus kunorudzirwa. Mikana yekuvandudzwa kwezvimwe zvinetso uye matambudziko ezvisikwa zvakanaka.
Nemaplasia ye umbilical arteri, nguva dzose
Inofanira kurangarirwa kuti kuonekwa kwechirwere chimwe chete chembilical rimwe chete hakufaniri kuva chikonzero chekubvisa pamuviri. Izvo chete zvakasanganiswa nemamwe maitiro uye chromosomal kusagadzikana kwakadaro chirwere chinokonzera ngozi kune hupenyu hwemwana uye kubudirira kwayo kunotevera.
