US wokuyera 2 trimester kubvumira kuziva proportionality mwana marangwanda kuzivisa mamiriro uropi ventricles, cerebellum, musana uye chiso ezvirevo. Zvikurukuru apo vazvione. mhuno, miromo, ziso panosangana, ivo atria kwemoyo, makuru midziyo, itsvo, dundira nemudumbu.

fetometry

Ultrassom Protocol 2 trimester zvichiitirwa kureva:

• nzvimbo placenta uye Ukobvu;
• mamiriro kukura dhigirii of placenta;
• Nhamba midziyo iri achiine rukuvhute tambo;
• Líquido Urume;
• mamiriro cervix uye uterine rusvingo uye zvinoshandiswa;
• fetometry zviratidzo.

Fetometry akadana nokuyerwa fetus saizi. Zvinosanganisira:

• kukura musoro mukuru mudumbu, huma uye mutsipa;
• denderedzwa dhayamita musoro uye abdominal sekamufarenzi;
• cephalic indekisi zvekuongorora sechivako musoro;
• kureba mapfupa refu (hudyu, tibia, zvikuru nezvidiki, humerus, ulna uye nharaunda) kumativi ose.

Decoding 2 trimester Ultrasound kunotibvumira kumisa developmentally yakakodzera gestational zera, kuongorora pachiyero fetus kukura, kuzosimbisa nguva yose pamuviri, kuziva lag kukura uye kuvapo abnormalities.

Intrauterine kukura angava symmetric uye asymmetric chimiro. Muchiitiko chokutanga, kukura riri Proportional kuti, uye zviratidzo zvose zvinoratidza Ultrasound slippage kubva ndozvakajairwa ari pamuviri.

Asymmetrical zvinhu ndeinotevera:

• kuyera chiuno sekamufarenzi pazasi ndozvakajairwa;
• kukura musoro uye DBC romuzvarirwo kwenguva refu;
• yakawedzera nhamba yacho chiutsi gasi / coolant uye CST / coolant.

Zvichienderana zvabuda vakawana, tinogona musiyano nhanho zvitatu backlog:

1. Backlog kwevhiki 2-3.
2. Backlog kwevhiki 3-4.
3. 5 kwemavhiki kana kupfuura.

Tinyatsonzwisisa mamiriro zvomukati ari mudumbu 2 trimester akazvitakura, Ultrasound

Cross-zvikamu musoro:

• kunze ari zvemamiriro chivako chiri chimiro ndimu, mabhanana uye Strawberry kana kutaurwa brachycephaly, kuvapo kaviri loop musoro kuti chiratidzo uropi edema;
• kudzidza kuvimbika nemamiriro dehenya mapfupa.

Tinyatsonzwisisa mamiriro uropi:

• ventriculomegaly zvinoratidza rakawedzerwa pfungwa ventricles;
• munyika vascular ino akaratidza kuvapo cysts;
• kuchengetwa ari cerebellum zvokurwara;
• neoplasms dzakaonekwa muna dehenya, izvo riri ayo nechepamusoro.

Kuziva zvisina kunanga zviratidzo syndrome:

• yakawedzera kure pakati nezvigadziko;
• muromo chiri pachena mamiriro;
• rurimi yakabudikira;
• akaratidza mwoyo kuremara;
• pfupa mupfupi Shin.

Chiso hurongwa:

• Profile kudzidza okumusoro shaya;
• pamberi Cyclops uye anophthalmia (tsvakurudzo munda ziso nezvigadziko);
• pamberi mumukaha muromo uye mukanwa (mumukaha mukanwa uye mumukaha muromo);
• kuvapo protrusion rokumusoro shaya.

Kana nomuzongoza anomalies akaona kuvapo cleavage munharaunda iyi. Zvinonzi pamwe zvemamiriro kukura musana. Uyu zvokurwara ngozi chaizvo.

A kushanda pakuvheneka pechipfuva. Izvi anotora achisiya pleural uye pericardial effusion - romuzvarirwo pericardial mvura bhendi haasi kupfuura 2mm. Zvinoratidzwa padanho pakunamata mumapapu - ose nemazvo kutanga zvemapapu anopindura chimwe muzvitatu muchinjikwa chikamu. Released madhigirii zvitatu:

• 0 - chakarurama chiedza echogenicity zvishoma echogenicity chiropa.
• 1 - maumbirwo echogenicity yemapapu uye chiropa yakaenzana;
• 2 - nechiidzo chiedza pamusoro echogenicity echogenicity chiropa.

Zvinonzi kunoyerwa cardiac goho (kuvapo Quad Zvivako pasina pathologies) uye vanonyanya nemidziyo. Uyewo vakaongorora dumbu, chiropa, ura, itsvo, dundira uye diaphragm.

Maonero of placenta

Kudzidza nhau uye kwenguva hunhu nenyere. Izvi zvinosanganisira placenta, achiine rukuvhute tambo uye Líquido amniótico. Kuita 2nd trimester Ultrasound kunotibvumira kuziva nzvimbo placenta pachinhu epamba zevu uterine cervix.

Kana zvakanga dzakabatanidzwa ari chinhambwe 5.5 masendimita pazasi dzomunyika os, vanoti pasi placentation, asi kana nemutemo yomukati zevo rose kana kuti chikamu charo, zviri uchapupu placenta previa.

Zvisinei, panguva yechitatu trimester, iye anogona kufamba uye kukwira kumusoro, saka ratidza fanira Ultrasound pa 27-28 vhiki.

placental ukobvu kunowedzera, zvichienderana gestational zera uye zvinofungidzirwa achitandadza kuda ari achiine rukuvhute tambo. Kana indekisi kuti ukobvu kupfuura 4,5 masendimita, inoratidza kuvapo edema mu fetus kusapindirana kweropa chirwere, zvinenge zvakawanda zvinotapukira hunhu kana kuvapo chirwere cheshuga.

The mwero kukura of placenta:

• About - kusvika vhiki 30;
• 1 - kusvika vhiki 27-36;
• 2 - 34-39 mavhiki;
• 3 - pashure pemavhiki 36.

Mamiriro Líquido mvura uye achiine rukuvhute tambo

Rastsenivanie Líquido Urume unokubvumira kumisa nhamba. Yakakwirira kana mwoyo kwevari chirwere chinokurwadzai fetus mudumbu, unokurudzira chimiro pathologies siyana.

Kuti huwandu Líquido mvura inotorwa Líquido amniótico indekisi. Kana idukusa 2 cm, tinotaura akaderedza kugutsikana, uye vanopfuura 8 masendimita - akavandudzika.

Kuongorora netambo nhamba nhumbi. Kazhinji, rine imwe tsinga uye mbiri arteries. Uyewo akataura pamberi achiine rukuvhute tambo muzvishwe aro yakatokura kumativi fetus mutsipa.

mamiriro muchibereko chemusikana

US dzakati of 2nd trimester pamuviri, uye zvinosanganisira mashoko pamusoro mamiriro muchibereko chemusikana. Akasarudzwa pamwero voltage. Hypertonia pamasvingo, kuvapo kurwadziwa kana ropa secretions previa chirwere.

Uterine rusvingo nzvimbo kukurukurwa pamwe pamberi kenza anomera (fibroids). Uyewo akataura zvinoitwa kukura kwavo, uye nzvimbo hama kuti embryo uye placenta. Kana wokuvhiya pamusoro dumbu vanofungidzirwa rumen:

1. mhando vakapfuma vanga. mamiriro ayo harina inclusions, inozivikanwa homogeneity uye evenness contours repasi chidimbu. Chokukomborerwa vanga Ukobvu asina kupfuura 3 mm.
2. Sauka pakuonekwa vanga. It inodaro kuremara. Somuenzaniso, ari rumen vakasunungurwa yakadzika niche, thinned rejira, yakakwirira rakawanda hyperechoic inclusions connective tishu.

mamiriro of cervix

Kuziva remuromo kusaita zvinhu nomazvo hurumende uterine cervix inofungidzirwa chokukomborerwa kureba kwayo uye muchinjikwa remuromo Canal. Kazhinji, kukura mutsipa anofanira zvinenge 35 mm. Nokuti vachigurisira kusvika 30 mm vakadzi, vakarangana mwana wavo wekutanga, uye vanosvika 20 mm wechipiri pamuviri, zvinokwanisika kutonga isthmic tserviakalnoy kukundikana.

kudzidza

US (2 trimester) kunoda hapana dzidzo chaiyo. Ura, pasinei pamberi gasi, otdvigaetsya kare akawedzera kukura dumbu. A dundira yakazara kunotsiviwa ne Líquido amniótico.

Asi vasati rizowedzerwa ropa kuti ongororo kunoda basa. Zuva nzira, mukadzi ane pamuviri havafaniri kudya chocolate, but uye zvakakangwa zvokudya. Uyezve, iwe haufaniri kudya kwemaawa 4-6 pamberi ropa kuzozvidzorerwa. Unogona kunwa mvura chete 4 kwemaawa, asi kwete aerated uye munguva yakawanda isina anopfuura 150 Rine mamiririta.

Zvinofanira kucherechedzwa kuti kuongorora rechitatu trimester haana zvinoda chero kudzidziswa.

Kana Ongororo iri kuitwa

Chirwere nguva yechipiri trimester - 16-20 mavhiki. Ichi ezvinhu inokosha kwazvo zvakakodzera kutsunga pachiyero mahormone muropa. Misi Ultrasound uwirirane rechipiri trimester nokukanganisika kuongorora ropa. Ultrassom zvinoitwa pakutanga, uye nemigumisiro vakatumira mumwe mukadzi pabvunzo ropa.

The kuongorora wechipiri nani kupfuura pamusoro 17 vhiki pamuviri, kana vhiki risati zuva.

Vanhu vazhinji vanoshamisika kupi kuti US 2 trimester akazvitakura? nzira iyi rinoitwa muruwa makiriniki, gynecological uye perinatal nzvimbo. Inopangidza uchapupu make-uzist vanachiremba.

Nemitemo kudzidza

Kudzidza vakadzi pamuviri inosanganisira dzinoverengeka chaiwo ezvinhu.

Ultrassom ongororo rinoitwa chete transabdominal, kuti iri paganda mudumbu. Kuti izvi zvidaro, mukadzi akaisa pasi pamubhedha, kuzarura mudumbu. abdominal penyika iri akazorwa gel. Chiremba achivatungamirira vachiongorora pamusoro rwaro kumberi. Kurwadziwa kana kusagadzikana ichi hachisi evanhu.

Uye sei zviri akaita nokukanganisika ongororo? anosvika yezvirwere A mukadzi mimba usina chawadya. Ropa rinotorwa kubva tsinga munguva uwandu milliliters anoverengeka. Murabhoritari, mukadzi rinopa Ultrasound zvabuda uye anozadza iri remibvunzo. The akagamuchira date chinogadzirwa ne chirongwa. Tinoguma chete takagadzirira mumazuva 14.

inopangidza

Decoding kunosanganisira dzinoverengeka zviratidzo, imwe neimwe ine yayo vasingambooni chakaipa nazvo. Result nokukanganisika kuongorora kunosanganisira kuziva zvakadini mahormone dzakadaro

• chorionic gonadotropin;
• estriol;
• fetoprotein;
• inhibin, kana akaita katatu uye quadruple bvunzo.

Results rechipiri kuongorora kuvimba ya pamuviri. Ivo kuongororwa maererano kukosha VeIOM. Izvi avhareji ukoshi iyo rinowanikwa kubva zera, muviri uremu uye pamuviri nedunhu nayo waanogara. dagnostiki zviratidzi akakamurwa kunokosha yakawanikwa iri kudzidza hombe nzwisa vakadzi vezera mhenyu iyoyo.

Kana kemikari iri kuwanda 0.5-2.5 Amai, riri kuonekwa pamwero dzose. Kana nhamba iri isingasviki kupiwa ukoshi kana vakutarisire kumusoro, muchiitiko ichi zvinonzi dzakaratidza zano mazvikokota.

Tsanangudzo Diagnostics trimester rechipiri iri rokuti pangozi pamwero neimwe zvokurwara. Zvinonzi akasarudzwa sezvo chikamu. High ngozi anoonekwa nechiidzo 1: 250 kana 1: 360 chero mhando zvokurwara. Saka padzakacherechedza Down raMwari Syndrome, Neural chubhu kuremara, Edwards, Patau. Izvi kunoda genetics kubvunza. Kana exponent 1: 100 vanogona rwakakurudzira invasive kuongororwa kunosanganisira kuziva inozoshandisirwa zvokurwara embryo kubudikidza yakatarwa okutodza.

Vamwe zvikanganiso zvingaitika zvikuru gare gare uye vachaitwa akaratidza chete kana yechipiri kuongorora dzimwe mavhiki 16-20 (2 trimester). Ultrasonography akaita panguva iyi, kufungisisa ichi chinokosha. Kana akaipa migumisiro rechipiri kuongorora achaudzwa kutsvaka mazano ane geneticist.
