Mushure mokunge nzira imwe neimwe ye-ultrasound, vakadzi vane pamuviri vanowana purogiramu yekudzidza mumaoko avo, iyo ine ruzivo rwakakosha pamusoro pekusimudzirwa kwechecheche. Chimwe chezvinhu zvakakosha pamiganho ye fetus ibasa re biparietal yemusoro, kana BPR. Chii chinonzi BDP che fetus uye kuti chii chinodiwa, kuti BDP uye kuberekwa kwakabatana sei, ndeipi mitemo ye biparietal musoro wemavhiki - iwe uchadzidza izvi zvose kubva munyaya yedu.
БПР - decoding
Munguva ye ultrasound, kunyatsotarirwa kunobhadharwa kuongorora musoro wemwana. Izvi hazvishamisi: uropi ndiyo nhengo inonyanya kukosha, kukura uye kubudirira kunobata zvakananga fetus. Sarudza uhu hwemusoro, uye naizvozvo hutano hwekuvandudza huchabatsira BDP. Biparietal ukuru ihwo huwandu hwe "upamhi" hwemusoro, hunoyera pamwe nechechi duku, kubva patemberi kuenda kutemberi.
Mukuwedzera kune BPR, ukuru hwepamberi-occipital (LZR) hunotsanangurwa zvakare - pamwe chete nenheyo huru, kubva pahuma kusvika kune occiput. Zvisinei, iyo yakakura parameter inoramba iine biparietal size: inoshandiswa kutsanangura nguva yehutano. Nokururamisa kwakakwana, izvi zvinogona kusimbiswa munguva yevhiki 12-28.
Maitiro eBDP anonyanya kukosha pakusarudza kuvepo kwehupenyu hwehupenyu. Kana uwandu hwemusoro wekufukidzana usingawirirane nehupamhi hwenharaunda yekuzvarwa, sarudzo inogadziriswa pamusoro pegadziriro yakarongeka iripo.
Biparietal ukuru hwemusoro - chimiro
Kuti kuongororwa kweBDP fetus kwevhiki, tafura dzakasarudzika dzakagadziridzwa, dzinoratidza huwandu hwemashoko ekukura kwebiparietal yemusoro we fetal uye kushanduka kwayo kunogamuchirwa. Mumatafura eBDP, fetal head size values inomiridzirwa se percentiles. Iyi inzira inokosha yekumirira nhamba dzezvechiremba, iyo, sekutonga, inoratidza huwandu hunokosha (50th percentile), pamwe nechezasi (5th percentile) uye kumusoro (95th percentile) miganhu yezvakanaka zvinokosha.
Kuti ushandise tafura iyi uye uone hurumende yeBDP ye fetus kwemavhiki, zvakakosha kuti uwane kukosha kwema50 percentile, zvakasara zvinokosha zvinotarisa miganhu yezviratidzo zvinowanzoitika. Semuenzaniso, pamasvondo gumi nemaviri mutemo weBDP uri 21 mm, uye kushivirira kwe18-24 mm. Izvi zvinoreva kuti apo BPR inokosha ye19 mm kune amai vanguva isingaperi haifanire kunetseka pamusoro pei - izvi zvinogona kunge zviripo zvekuvandudzwa kwechecheche.
BDP fetus mutafura - kutsauka kubva pachimiro
Zvinowanzoitika kuti zviratidzo zveBDP zvinopfuura miganhu inogamuchirwa. Izvi zvinorevei? Kutanga, kuitira kuti ave nechokwadi chekusavapo kwehutachiona, chiremba anofanira kuongorora zvimwe zviyero zve fetus (kureba kwehudyu, mimba yepamuviri). Kana dzose dzacho dzichipfuura chimiro cheimwe kana vhiki dzinoverengeka, zvino inogona kutaura nezvechibereko chikuru. Kana mamwe maitiro e-fetometry akajairika, zvino zvinokwanisika kuti mwana ari kukura saizvozvowo, uye mushure memavhiki mashomanana zviyero zvese zvinoshandiswa.
Kunyange zvakadaro, kukanganisa kukuru muhutano hweBDP kubva pachimiro kunogona kuratidza zvinetso zvakakomba. Nokudaro, kuwedzera biparietal ukuru kunowanikwa mumakumbo europi kana ehenya remapfupa, uyewo mumucherechedzo weharia uye hydrocephalus . Muzviitiko izvi zvose, kunze kwehydrocephalus, mukadzi ane pamuviri anopiwa kuvhara pamuviri, sezvo izvi zvinokonzera kusagadzikana nehupenyu. Apo hydrocephalus inowanikwa, mishonga inorwisa mabhakitiriya inochengetwa uye inongowanikwa muzviitiko zvisingashamisi (mukushayikwa kwemigumisiro yechirwere) kubvisa kubvisa pamuviri.
Izvo zvakaderedzwa zvakakoswa kukura kwe musoro we fetal uyewo hazvirevi zvakanaka: sekutonga, izvi zvinoreva kushandiswa kwehuropi kana kusavapo kwezvimwe zvivako zvaro (cerebellum kana cerebral hemispheres). Munyaya iyi, panguva ipi zvayo kuberekwa kunoparadzaniswa.
Muchikamu chechitatu, BDP yakaderedzwa inoratidza kuvepo kwechirwere chema intrauterine kukurumidza kukurumidza. Kurapa kunoitwa nemishonga inovandudza uterine-placental blood flow (kurantil, actovegin, nezvimwewo).
