Mimba: sinthani zachilendo za placenta

Pamene placenta imayikidwa pansi

Mpaka sabata la 18 la mimba, ma placenta ambiri amakhala m'munsi mwa chiberekero, ndipo izi siziri vuto. Ambiri "amasamukira" m'mwamba pamene chiberekero chikukula. Gawo laling'ono (1/200) limayikidwa pafupi ndi khomo lachiberekero pamtunda wa gawo lapansi (chinthu chomwe chimapangidwa mu 3 trimester pakati pa khomo lachiberekero ndi thupi la chiberekero). Izi zimatchedwa placenta previa. Izi sizimangopangitsa kuti zikhale zovuta kuti mwanayo atuluke, koma akhoza kuyambitsa magazi pamene kugunda kumachitika. Zovuta zimadalira mtunda wa placenta kuchokera ku khomo lachiberekero. Nthawi zina, imakwirira m'mimba ndipo kubadwa kumatha kuchitika mwa cesarean.

Kodi thumba lakumbuyo, latuluka, fundal placenta ndi chiyani?

Timalankhula za thumba lakumbuyo kapena lakumbuyo kutengera malo omwe thumba lilili, kaya kumbuyo kapena kutsogolo kwa chiberekero. Timalankhulanso za fundal placenta pamene thumba lili pansi pa chiberekero. Ichi ndi chisonyezero chabe cha malo a placenta; Mawuwa sakutanthauza kudwala kapena kusakhazikika bwino kwa placenta.

Pamene placenta ili ndi kachilombo

Majeremusi a amayi amatha kufika ku placenta m'njira zosiyanasiyana. Kupyolera mu mwazi, kupyolera mu khomo lachiberekero kapena kuchokera mu chiberekero chomwe. Kutengera tsiku la matenda, zotsatira zake pa mimba zimasiyanasiyana (kupita padera, kuchedwa kwa intrauterine kukula, kubereka msanga, kutenga nawo gawo kwa mwana wakhanda, etc.). Tizilombo tating'onoting'ono titha kukhala pagulu la placenta kapena kukhala pa nembanemba ya amniotic. Ma ultrasound nthawi zina amawonetsa matenda a placenta, koma sizimawonekera nthawi zonse. Mwana akabadwa, nkhokwe imatumizidwa ku labotale kuti idziwe kachilomboka motsimikiza.

Pamene placenta ili ndi mawonekedwe oseketsa

Kumapeto kwa mimba, placenta ("pancake" mu Chilatini) imawoneka ngati diski 20 cm mulifupi ndi 35 mm wandiweyani. Kulemera kwake ndi 500-600 g. Nthawi ndi nthawi, zimawoneka zosiyana. M'malo mopanga misa imodzi yayikulu, imagawidwa m'magawo awiri olumikizidwa ndi chingwe (placenta bi-partita). Nthawi zina, ndi kagawo kakang'ono ka placenta, komwe kamakhala kutali ndi misa yayikulu (aberrant cotyledon). Nthawi zambiri, zinthu izi sizibweretsa vuto.

Phula likatuluka msanga

Chilichonse chikayenda bwino, placenta imasiyana ndi chiberekero panthawi yobereka. Zomwe zimachitika asanabadwe, hematoma (thumba lamagazi) limapangidwa pakati pa khoma la uterine ndi placenta zomwe zimayambitsa kusokonezeka kwa kusinthana kwa amayi ndi mwana. Ngati hematoma imakhudza gawo laling'ono chabe la placenta, kuopsa kwake kumakhala kochepa, ndipo kugona m'chipatala ndi kupuma nthawi zambiri kumapangitsa kuti mimba ipitirire bwino. Pamene detachment imakhudza latuluka lonse, amatchedwa retro-placental hematoma. Vutoli, mwamwayi losachitika kawirikawiri, likhoza kukhala ndi zotsatirapo zoopsa kwa mayi ndi mwana. Chifukwa? Sizidziwika bwino, koma pali zinthu zomwe zimathandizira monga preeclampsia, kusuta kapena kugwedezeka m'mimba. Zizindikiro zoyamba zimakhala zodziwika bwino: kutuluka magazi komanso kupweteka kwadzidzidzi m'mimba, komwe kumatsatiridwa ndi kuvutika kwa mwana wosabadwayo. Matendawa akangopangidwa, palibe nthawi yowononga! Kutuluka kwa khanda ndikofunikira.

Placenta accreta: pamene placenta imamera bwino

Kawirikawiri, placenta imayikidwa pamtunda wa chiberekero. Dongosololi, lomwe limapangidwa atangoyamba kumene kukhala ndi pakati, limatha kuchitika modabwitsa. Izi ndizochitika pamene kumatira kwa gawo kapena latuluka lonse kumafikira mozama kuposa momwe ziyenera kukhalira muchiberekero. Kenako timalankhula za placenta accreta. Mwamwayi kukhazikitsidwa kosowa kumeneku (1/2500 mpaka 1/1000 oyembekezera) kumatha kukhala kovutirapo chifukwa chotaya magazi panthawi yobereka. Izi zili choncho chifukwa thumba lokhazikika pakhoma la chiberekero silingatuluke bwinobwino. Mankhwalawa ndi ovuta, okhudza gulu lonse lachipatala, ndipo zimadalira makamaka kukula kwa magazi.

Pamene placenta imakula mosadziwika bwino

Mtundu uwu wa anomaly ndi osowa, pa dongosolo la mimba imodzi mu 1. Imakumana ndi zomwe zimatchedwa molar mimba (kapena hydatidiform moles). Chiyambi chake ndi chromosomal ndipo chimachokera ku umuna. Kutuluka magazi kumayambiriro kwa mimba, nseru kapena kusanza, chiberekero chofewa, chokulirapo kuposa nthawi zonse, chikhoza kuyika chip mu khutu. Matendawa amatsimikiziridwa ndi ultrasound. Pali mitundu iwiri ya timadontho ta hydatidiform. Itha kukhala mole "yathunthu", momwe mulibe mwana wosabadwayo koma placenta yomwe imapitilira kukula kukhala ma cysts angapo ndikuwoneka ngati mulu wa mphesa, kapena gawo lomwe mwana wosabadwayo amatha kumera. mosadziwika bwino, kachiwiri ndi kukula kwakukulu kwa placenta. Pambuyo pochotsa mimba ya molar, mlingo wokhazikika wa mahomoni oyembekezera (hCG) amaperekedwa kwa miyezi ingapo. Zowonadi, nthawi zambiri amakhala okwera kwambiri m'matenda amtunduwu, koma ayenera kukhala opanda pake. Nthawi zina hydatidiform mole imapitilirabe, kapena imafalikira ku ziwalo zina. Izi zimafuna kuwunika kwambiri ndi chithandizo.
