Qee lub sij hawm, cov niam tsev noj qab haus huv muab yug rau cov menyuam uas muaj qhov tsis xws luag morphological: qhov tsis muaj phalanges ntawm cov ntiv tes, caj npab thiab lub taub hau. Cov niam txiv tuaj poob siab, cem lawv tus kheej lossis kws kho mob txog qhov tshwm sim rau lawv tus menyuam. Qee lub sij hawm nws los txog rau kev hais plaub. Tab sis dab tsi tiag ua rau cov kev yug me nyuam no?
Definition
Amniotic bands, txwv tsis pub hu ua "amniotic adhesions" lossis "Simonard's bands", yog ib qho kev sib tw ntawm cov ntaub so ntswg amnion uas ncab ntawm phab ntsa ntawm lub tsev menyuam. Raws li txoj cai, nws tsis ua mob rau lub embryo thiab tsis muaj teeb meem hauv kev yug menyuam. Tab sis tsawg zaus, qhov tshwm sim loj tuaj yeem ua tau.
Amniotic bands yog cov xov fibers uas tshwm sim hauv lub hnab amniotic. Lawv tuaj yeem rub lossis qhwv txoj hlua khi, txuas mus rau qhov chaw ntawm lub cev ntawm tus menyuam hauv plab, ua rau muaj qhov tsis zoo (kev txiav caj npab, ceg, ntiv tes lossis lawv cov phalanges, qee zaum decapitation).
Yog vim li cas
Muaj ob txoj kev xav vim li casamniotic constrictions tshwm. Cov laj thawj rau qhov tshwm sim no tau piav qhia los ntawm kev nquag ruptures ntawm lub zais zis amniotic thaum cev xeeb tub. Txij li thaum lub chorion tseem nyob twj ywm, tsis muaj kev hem thawj ntawm kev cuam tshuam hauv kev loj hlob ntawm lub embryo, tab sis cov xov uas tshwm sim vim ruptures ntab dawb hauv cov kua amniotic. Lawv tuaj yeem khi rau qhov chaw ntawm lub cev ntawm tus menyuam hauv plab. Thaum cev xeeb tub, tus menyuam loj hlob, tab sis cov xov tseem zoo li qub, yog li muaj cov ntaub so ntswg compression, ischemia thiab necrosis.
Qee lub sijhawm tom qab, qhov kev xav thib ob tau tshwm sim, raws li thawj zaug tsis haum rau cov neeg tsis ntseeg, uas pom tias cov kab mob amniotic (fibrous filaments hauv plab ntawm tus poj niam cev xeeb tub) tshwm sim ib txhij nrog lwm yam kev tsis haum xeeb hauv lub cev, xws li cleft. di ncauj los yog cleft palate. Cov kws kho mob no tau kwv yees tias cov kab mob no yog vim muaj vascular lossis fetal circulatory disorders.
Lwm qhov kev xaiv rau kev txhim kho cov xwm txheej yog kab mob hauv lub cev, nrog rau kev raug mob thaum cev xeeb tub, kev tsis txaus ntseeg ntawm qhov chaw mos (ob npaug ntawm lub tsev menyuam, lub tsev menyuam bicornuate, thiab lwm yam), CSI (isthmic-cervical insufficiency), o ntawm amnion, endometritis, oligohydramnios. Tab sis tsis muaj ib qho ntawm cov kev xav no tau lees paub tseeb.
Diagnosis
Nyob rau hauv feem ntau, kev kuaj mob thiab kev kuaj pom tsis tuaj yeem kuaj pom amniotic constrictions. Daim duab los ntawm kev kawm ultrasound tsis qhia, vim cov xov no nyias nyias. Indirectly, koj tuaj yeem txiav txim siab qhov loj thiab o ntawm caj dab nyob rau hauv qhov chaw ntawm compression. Dav dav mus rau qhov lojoverdiagnosis ntawm no pathology. Yog li, yog tias tus kws kho mob xav tias muaj kab mob amniotic, tus poj niam cev xeeb tub raug xa mus rau MRI lossis 3D ultrasound.
Ntau tshaj li ib nrab ntawm qhov kuaj pom amniotic constrictions ntawm rov ua ultrasounds tsis pom vim lawv qhov tawg.
Statistics
Nyob ntawm cov khoom siv ntawm lub tsev kho mob antenatal, qhov zaus uas kuaj pom muaj amniotic constrictions tuaj yeem nyob ntawm 1: 1200 txog 1: 15,000 yug. Nws ntseeg hais tias ob puas tawm ntawm kaum txhiab tus nchuav menyuam tshwm sim vim li no. Hauv yim caum feem pua ntawm cov neeg mob, Simonard's bands deform cov ntiv tes thiab tes, thiab lwm kaum feem pua yog compression ntawm txoj hlab ntaws. Nws yog tsim cov pob caus ntawm txoj hlab ntaws uas ua rau hypoxia thiab antenatal tuag ntawm fetus.
Zoo hmoo, feem ntau qhov kev kuaj mob ntawm "amniotic band syndrome" tsis tau lees paub hauv tsev kho mob, lossis cov fibers sutures tsis ua rau muaj kev puas tsuaj loj rau tus menyuam hauv plab.
Qhov ntxim nyiam uas cov kab amniotic yuav tshwm sim thaum cev xeeb tub yog qhov tsawg heev. Qhov no tsis yog kab mob caj ces. Raws li txoj cai, genomic lossis chromosomal kev hloov pauv tshwm sim symmetrically, tab sis nyob rau hauv cov ntaub ntawv no, cov xov yog txuas kiag li random. Yog hais tias thaum cev xeeb tub thawj zaug tus me nyuam muaj Simonard strands, qhov no tsis txhais hais tias cov me nyuam tom ntej yuav raug mob. Tsis tas li ntawd, qhov no tsis tau txhais hais tias tus menyuam uas muaj qhov tsis zoo yuav yug los ntawm cov niam txiv uas tau raug mob amniotic constriction syndrome nyob rau hauv utero.
Txhais tau
Txawm hais tias amniotic constriction tsis yog ib tug neeg tuag taus pathology, nws qhov tshwm sim tuaj yeem nyuaj siab heev. Vim qhov tseeb tias cov strands tuaj yeem cuam tshuam qhov chaw ntawm lub cev ntawm tus menyuam hauv plab, lymph stagnation tsim. Qhov no ua rau edema thiab necrosis. Tom qab yug me nyuam, xws li cov ceg yuav tsum tau txiav, txwv tsis pub CRUSH syndrome yuav tsim: co toxins uas tau sau nyob rau hauv lub anesthetized ib feem ntawm lub caj dab yuav nkag mus rau hauv lub systemic ncig thiab pib lom tus me nyuam lub cev. Qhov no tuaj yeem ua rau nws tuag. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tshem tawm cov ceg yog tias nws tsis siv tau lawm. Thiab sai li sai tau.
Tsis tas li ntawd, nrog rau cov tsos mob ntawm amniotic constriction, kev nyuaj siab ntawm cov ceg thiab cov ntiv tes mus rau qhov chaw ze ntawm cov ceg ceg yog ua tau. Nws tsis yog qhov txawv ntawm cov menyuam yaus no kom muaj fusions ntawm cov ntiv tes lossis phalanges ntawm cov ntiv tes thiab cov ntiv taw. Qee zaum, ntxiv rau kev txwv, tus menyuam muaj lwm yam stigmas ntawm disembryogenesis: clefts ntawm lub siab tawv thiab daim di ncauj. Muaj tsawg zaus, muaj kev ua txhaum tag nrho ntawm txoj kev loj hlob ntawm tus txha nqaj qaum thiab lub ntsej muag pob txha taub hau, kev tshwm sim ntawm lub plab kab mob, txoj hlab ntaws atresia.
Yog hais tias qhov constriction cuam tshuam rau cov hlab ntsha nyob ze ntawm daim tawv nqaij, ces ib tug hemangioma yog tsim nyob rau hauv qhov chaw no. Cov qog yuav tsum tau muab tshem tawm tom qab yug me nyuam.
Qee cov kws tshawb fawb pom qhov sib txuas ntawm Simonard bands thiab clubfoot. Qhov no yog vim lub fact tias ob txhais ceg ntawm fetus yog tsau nrog fibrous threads, yog li cov phab ntsa ntawm lub tsev me nyuam yuav nyem ob txhais taw ntawm fetus. Hauv nees nkaum feem pua ntawm cov neeg mob, qhov no pathology yog ob sab. Lwm qhov kev pheej hmoo uas tus kws kho obstetrician-gynecologist yuav tsum xav txog yog kev yug ntxov ntxov. MuabCov teeb meem yog ib qho tshwm sim hauv cev xeeb tub nrog amniotic constriction syndrome.
Kev kho mob
Raws li txoj cai, tus kab mob no tsis kho hauv lub tsev menyuam. Hauv kev kho mob, muaj cov xwm txheej casuistic thaum ua haujlwm transvaginal lossis laparoscopic. Tab sis qhov no yog ib qho kev ntsuas hnyav, vim lub cev tseem ceeb tau nyem. Tab sis cov no yog qhov tsis tshua muaj amniotic constrictions. Kev kho mob feem ntau yog muab tom qab tus menyuam yug los.
Cov fibers raug muab tshem tawm thiab, yog tias tsim nyog, ib feem ntawm lub caj pas yog txiav. Txhawm rau txhim kho lub neej zoo, koj tuaj yeem hloov cov ntiv tes ntawm ko taw mus rau txhais tes.
Huab cua
Kev ntsuas rau lub neej thiab kev noj qab haus huv feem ntau yog qhov zoo. Cov menyuam feem ntau loj hlob thiab loj hlob raws li hnub nyoog. Txhua xyoo, limb prostheses tau txhim kho, yog li yog tias koj plam lub hauv pliaj, tes, qis ceg lossis ko taw, nws muaj peev xwm muab cov khoom hloov pauv. Cov menyuam yaus raug txhawb kom hloov lawv cov hniav hniav thaum lawv loj hlob tuaj. Yog hais tias lub constriction ua rau ib tug me ntsis functional defect, ces cov tshuaj pleev ib ce tsis xws luag yuav tshem tawm los ntawm transplanting tus ntiv tes, nrog rau lawv cov phalanges.
Cov neeg uas muaj amniotic constriction syndrome tuaj yeem muaj cov menyuam noj qab nyob zoo, vim tias tus kab mob no tsis tau txais txiaj ntsig.
Celebrities uas muaj Simonard bands
Ntawm yog hnub uas cov neeg tuag taus nkaum hauv lawv lub tsev thiab raug cuam tshuam los ntawm tib neeg. Tam sim nolawv tuaj yeem nyob nrog tsis muaj kev txwv, tuav haujlwm tseem ceeb rau pej xeem, ua si kis las, tshwm hauv TV thiab koom nrog kev sib tw zoo nkauj.
