Ndozvakajairwa of nasal mapfupa muvhiki 12: zviratidzo. Dzemunharaunda ari kuongorora pamuviri rokutanga: Kureba nasal mapfupa

mushonga Modern akaita chaizvo mberi panyaya ongororo nevakadzi vane pamuviri, uye kana kwokutanga zvaionekwa zvikuru zvakakwana kupfuura Ultrasound kuzviongorora mudumbu uye zvakaitika zvimwe miedzo, ipapo nhasi chikamu ichi wevarwere riri pasi takarinda pokudzora nyanzvi uye kaviri nenguva dzirikure bvunzo uye maitirwe ezvinhu. Kumboda vari nechinangwa Pakusarudza mamiriro kukura mwana ari mudumbu amai nenguva zvokuongorora pakati abnormalities siyana. Kusanganisira - ultrasonic vasabatwa maitiro akadai mwero nasal mapfupa, kunze pashure pemavhiki gumi pamuviri.

Kudikanwa kuyera fetus nasal mapfupa

Steam, quadrangular nasal mapfupa vagara vandifungira Ultrasound kuri munguva nzira pa vhiki 12 gestation. Kusavapo Its iyi kana yakatsauka kubva akagamuchira tsika akazotevera uchapupu zvakaipa -natal kutanga mwana, uyezve, anogona zviratidzo pamberi nomwana syndrome. Mumamiriro ezvinhu akadaro, zvakanga akataura mutemo unoti okuwedzera yokuedzwa.

Dzimwe nyanzvi, achiziva mitemo wokutanga kuongorora, vachishandisa okufananidza tabulated netsika nokuenzanisa tsika dzavo nemigumisiro yacho Ultrasound. Zvakare, hatifaniri kukanganwa kuti chokutanga munguva vhiki 10-12 pamuviri ndechokuti kuvapo fetus nasal pfupa uye chipimo havasi kudaro kuratidzwa, nekuti chromosomal abnormalities pamusoro Ossificação em kuitika gare gare.

nasal pfupa parameters panguva dzakasiyana zvokukura pamuviri

Munhu nguva fetus kukura vanoonekwa nevamwe regularities. Mumwe mukuru parameters ndiyo Kureba nasal mapfupa. Ndozvakajairwa of nasal mapfupa muvhiki 12 anenge matatu millimeters pakureba. Gare gare, kuna 21 fung vhiki, nhamba iyi kunosvika 5-5,7 millimeters, uye 35th vhiki - 9 millimeters.

Kururama Ultrasound kuyerwa embryo hakubvi chete akakwana zvokushandisa, asiwo ruzivo uye professionalism.

Tafura huru parameters ari nasal mapfupa

Norma nasal pfupa pa vhiki 12 fetus, uyewo haizopereri mwedzi mukadzi ane pamuviri, systematized uye ndipiyona pokutangira kudzidza migumisiro vanodzidza Ultrasound. Pahwaro mashoko awanika, vanachiremba murinde nokufamba pamuviri kushanya mwana uye kuona kuvapo kana kusavapo anomalies.

Kana nasal mapfupa hauna mufanidziro, uye pakora yacho thickened, ipapo chinhu chaizvo mukuru ndingangokuvara mwana pamwe chirwere cheDown syndrome kana vakaremara chiso. Achiziva ichi, vabereki vakawanda vanosarudza pamuviri. Sezvo mwana ane utano - iri basa kwete vanamai chete, asiwo vanachiremba, zvakadai basa rinokosha rakapiwa zviratidzo zvakadai mwero nasal mapfupa muvhiki 12. The tafura pazasi rinopa tsananguro imwe yakajeka zvibereko zvayo paaiita pamuviri.

Kuti inorondedzera pakureba mapfupa nasal munhu mudumbu?

Mushure wegumi vhiki gestation pamuviri anogona kuita kuyerwa inokosha zvechadenga azvarwa. nasal mapfupa wokuyera mumavhiki 12 inofanira kusangana runodiwa parameters, zvimwe uchawana kufunga zvichibvira zvikuru chromosomal matambudziko mwana asati aberekwa. Hypoplasia vanoonekwa chiratidzo kunzwisisa zvirwere zvakadai syndrome, Edwards, Patau, Turner, et unto.

For zvabuda neyakarurama kugadza nyanzvi fetus Ultrasound, uye kana kuzodzosera kusimbisa kuti mwero nasal mapfupa asingadi kuwirirana runodiwa kwakatarwa, aite nemagene Kuongororwa kuti Líquido amniótico. Izvi kubvumira kuti chinangwa vaongorore mamiriro intrauterine mwana nokuti ezvinhu ichi kuunganidza okisijeni, carbon dioxide, mahormone, fetus kuchinjanisa zvinhu zvigadzirwa, makemikari.

Kururama Diagnostics ano

Nechokwadi chezvinhu migumisiro Ultrasound nechirwere ndechokuti nasal pfupa parameters mwana idukusa dzose, vabereki kukanda zvisingaperi mwoyo. Regai chete sei, nokuda parameter ichi hazvikwani rokuongorora Down kuti urwere kana zvimwe chakakomba pathological ezvinhu. Uye kunyange zvazvo pakutanga kuongorora mitemo pamwero INDICATIVE, vanofanira zvakadzikama kumirira migumisiro zvakadzama apiwa kuzviongorora.

Vachiri zvakafanira kunzwisisa kuti mwana wose munguva fetus yakasiyana, nekuti kukura wacho nhengo dzomuviri uchava akasiyana, kusanganisira nasal mapfupa muvhiki 12. Asi kana ari mudumbu kudzidza chinoratidza zviparare pachena zvomukati uye kupfupikisa maoko nemakumbo, mune zviitiko izvi, uye zvinokuchengetedzai kutaura pakupona.

Chii pamuviri kuongorora

Pamuviri kuongorora - rakasiyana ongororo amai vanepamuviri kuti ticherechedze ngozi vachiberekwa uye akawana pathological ezvinhu fetus, migumisiro ayo ichienzaniswa avhareji tsika.

In rokutanga trimester (10-12 mavhiki), perinatal kuongorora anobvumira mangwanani zvakakwana kuti vazive anomalies ari uwandu chromosomal abdominal rusvingo kuremara uye zvokurwara ari Neural chubhu, uyewo siyana kuipa vana kutyisidzira zvavo.

Zvichienderana chokupika hCG uye PAPP zvinoratidza pamuviri, uyewo kukosha nuchal translucency ukobvu ari mudumbu, kuzotonga mukana zvichiita kuremara. Kana tanga kuongorora mitemo regai kunowirirana chokupika Analyses, mukadzi ane pamuviri iri ushandiswe kudzidza genetics nezveramangwana mwana uye chorionic villus zvakabudiswa.

Chii hypoplastic nasal mapfupa ari fetuses

Ndozvakajairwa of nasal mapfupa muvhiki 12 panguva Ultrasound rinoratidza, kukura zvakanaka utano ari mudumbu mukutanga pamuviri. Kana kureba kwayo dzikatsauka kugamuchirwa mureza yakananga kudzikira, saka pane hypoplasia kubva nasal mapfupa. Asi pane asina zviitiko apo nhamba haitauri wayo mukuru kuongorora. Ipapo mubvunzo kuti aplasia pamusoro nasal mapfupa, mune mamwe mazwi, pasina zvakakwana simba.

Nei kutyorwa zvakadaro zviitike?

Kutaura zvazviri, zvinokonzera pathological zvarakasiya kubva dzose tsika vaviri fetus nasal mapfupa kureba yakatarwa, uye vose vane yakasiyana hunhu. Izvi zvinogona kuva Somuenzaniso, chirwere udhakwa yomubereki kana zvakakomba zvinokonzerwa nokusvuta. Pangozi ndivo vanonzi akaiswa vakadzi vakambova chikosoro, chikosoro nedzimwe zvirwere zviri trimester akazvitakura rokutanga.

Panewo zvimwe zvikonzero nei mwero nasal mapfupa muvhiki 12, fetus asingadi kuwana, zvinoti:

• mishonga nezvimwe zvinodhaka simba;
• nokufumura wegamma mwaranzi;
• izvi pamusoro womukadzi muviri chinokuvadza zvezvakatipoteredza zvinhu;
• mavanga;
• overheating refu mukadzi pamuviri.

Saka, kunze chromosomal abnormalities, uye vanonzi kuvabereki kubatwa, mararamiro uye utano amai vanepamuviri zvakananga kukanganisa kukura kwaro mudumbu mune utero. Asi mushonga ano, nemhaka nzira itsva nechirwere, vachibvumira mangwanani zvakakwana mune nhumbu kuziva chromosomal abnormalities uye kuongorora mwana, zvakaipira izvo zvinogona Down syndrome. Chero zvazvingava, ndiye chiremba pahwaro ongororo yakarurama uye tsvakurudzo anokwanisa kuona chirwere wechokwadi kana ushe kubva zvichibvira njodzi.
