I-plexus ye-choroid iyindawo yechungechunge eyenza i-cerebrospinal fluid. I-Cerebrospinal fluid yizinto ezizungezile ubuchopho nomgogodla. I-plexus ye-choroid ayiyona indawo yobuchopho obathintekayo ekucabangeni. Ama-plexus cysts ama-Choroid yizikhala ezigcwele amanzi e-plexus ye-choroid efana ne-blisters noma amabhulobhu. I-proidus cysts ayiyona i-tumor noma umdlavuza, futhi iyophela yodwa phakathi kwamasonto angu-24 kuya kwangu-26 okukhulelwa.
I-proidus cysts ye-Choroid, futhi yona, ayiyona inkinga futhi ayiphazamisi umsebenzi wobuchopho.
Kubonakala cishe ngo-1% (1/100) kuwo wonke ama-second-trimester ultrasounds. I-plexus cysts ye-Choroid ingabonakala kunhlangothi eyodwa noma zombili zobuchopho futhi inani, ubukhulu, nokuma kwama-cysts kungahluka. I-proidus cysts ye-Choroid itholakala nasezingane ezinempilo nabantu abadala. Nakuba zizwakala zishaqisayo, azihlanganiswa nanoma yikuphi ukukhubazeka emsebenzini obuchopho. Ukukhathazeka okukhulu nge-choroid plexus cysts ukuthi bangase babe "uphawu oluphansi" lwe- Down syndrome . I-"marker soft" yiyona into engeke ibangele ingane yakho ibe yinkinga, kodwa ingase ikhombise ukuthi umntwana unesimo esibi kakhulu esingaphansi. Ezinye izimpawu ezithandekayo ze-Down syndrome zihlanganisa ukulinganisa kwe-femur okunciphisisiwe, ukuxilongwa kwe-renal ye-renal, isilonda se-echogenic, i-echogenic foci enhliziyweni, i-translucency ye-fetal yenyusayo eyengeziwe (indawo engemuva kwentanyeni), kanye nethambo elingenalutho emasimini yokuqala .
I-Ultrasound Phakathi Nokukhulelwa Ne-Plexus Cysts Ye-Choroid
I-ultrasound yinto ehlolwayo ngesikhathi sokukhulelwa. Isebenzisa amagagasi omsindo ukubuka noma ukubona ngeso lengqondo ingane yakho ngesikhathi sokukhulelwa. Ayikho ingozi kumntwana ehlotshaniswa ne-ultrasound ngesikhathi sokukhulelwa kanti abesifazane abaningi bayoba neyodwa noma emibili ye-ultrasound, ngezizathu ezihlukahlukene, esikhathini sokukhulelwa kwabo.
Kungenzeka ukuthi i-proidus cysts ye-choroid iyinto evamile kuwe ingane futhi uzoba nengane evamile, enempilo. Kodwa-ke, abanye abacwaningi baye babona ubudlelwane phakathi kwala ma-cysts nokungajwayelekile kwe-chromosome njenge-Down syndrome ne- trisomy 18 . Uma i-plexus cysts ne-orroid noma ezinye izimpawu zibonakala kwi-ultrasound, ungase unikezwe ukuhlolwa okungaphezulu njengezinga 2 noma i-ultrasound eningiliziwe, noma i-amniocentesis.
Iyini Ingozi Ukuthi Ingane Inayo I-Down Syndrome Noma i-Trisomy 18?
Ikhono lokuthi ingane egcwele i-plexus cyst (s) engama-chromosome engavamile iyabonakala ibe yi-1% noma ngaphansi uma ngabe konke ukuhlolwa kwe-ultrasound kuvamile. Lokhu kusho ukuthi kunamathuba angu-99% noma ngaphezulu ukuthi ingane ayinayo i-chromosome engavamile. Abanye abacwaningi baye babika izingozi ezingaphezulu kuka-1% kanti abanye babone ukuthi akukho hlangana phakathi kwala ma-cysts nokungajwayelekile kwe-chromosome. Kungcono ukuxoxa ngalesi sifo se-ultrasound kanye nengozi yakho nodokotela wakho.
Ingabe i-Down Syndrome namanye ama-Trisomi angatholakala ku-Ultrasound?
Cha. I-Ultrasound ivumela udokotela ukuba abone ngeso lengqondo ingane futhi abone amanye amamaki angokomzimba angabonisa ingozi eyengeziwe, kodwa i-ultrasound yedwa ayikwazi ukuxilongwa okungavamile kwe-chromosome njenge-Down syndrome noma i-trisomy 18.
Indlela kuphela yokuthola ukuxilongwa kwe-Down syndrome noma enye into engavamile ye-chromosome ekukhulelwe yi-test amniocentesis.
Kubalulekile ukukhumbula ukuthi ngenkathi i-ultrasound ingakwazi ukuthola ukuthi i-Down syndrome noma amanye ama-chromosomes angavamile, i-ultrasound evamile iyasiqinisekisa kodwa akuyona isiqinisekiso lapho ingane iphilile ngokuphelele. Akukhona ukuhlolwa kokubeletha okungaqeda konke ukukhubazeka kokuzalwa noma izinhlobo zokulinda kwengqondo.
Ama-Chromosome abonakala kanjani ngesikhathi sokukhulelwa?
Indlela kuphela yokutshela ukuthi i-fetus inokungajwayelekile kwe-chromosome efana ne-Down syndrome noma i-trisomy 18 ukwenza i-amniocentesis evame ukuqhutshwa ku-trimester yesibili.
Ngesikhathi i-amniocenteis, inaliti encane ifakwa ngodonga lomama wesisu ngaphakathi kwesibeletho futhi inani elincane elizungezile ingane lisusiwe. I-chromosomes ye-fetal ihlolwa ngokusebenzisa ukuhlolwa kwe-FISH kanye / noma ukuhlolwa kwe-karyotype . Imiphumela evela ekuhlolweni kwe-FISH, ngenkathi ilinganiselwe, ivame ukutholakala ezinsukwini ezingu-3 kuya kwezingu-4 futhi imiphumela yokuhlaziya okugcwele karyotype ngokuvamile ithatha amasonto amabili. Imiphumela yalokhu kuhlola ingaphezulu kuka-99% enembile ekuhloleni i-Down syndrome nezinye izinkinga.
Ngenxa yokuthi i-plexus cysts ye-choroid ayibonakali kuze kube yilapho i-trimester yesibili yokukhulelwa, ukuhlolwa kwe-CVS (okwenziwe ku-trimester yokuqala yokukhulelwa) akuyona inketho. Uma ngabe ube nokuhlolwa okujwayelekile kwe-CVS, ngakho-ke asikho isizathu sokukhathazeka ngokuthola i-proidus cysts ye-choroid kwi-ultrasound yakho. I-plexus cyst ye-choroid ibhekwa njengokuhluka okuvamile komuntu okungaziwa ukuthi kuyingozi kumntwana.
Uma unquma ukuba ne-amniocenteis futhi imiphumela iyinto evamile, akudingeki ukuhlolwa okwengeziwe. I-plexus cyst ye-choroid ibhekwa njengokuhluka okuvamile komuntu okungaziwa ukuthi kuyingozi kumntwana.
Okubalulekile
I-proidus cysts ye-Choroid, ngenkathi izwakala isabisa, iyinto ejwayelekile yokuthola i-ultrasound. Ngokuvame ukutholakala okuvamile okungekho okushiwo ukukhulelwa. Ngokuvamile (okungaphansi kwe-1% yesikhathi), bangaba umaka wokuthi ingane isifo esingavamile se-chromosome njenge-Down syndrome noma i-trisomy 18. Uma kubonakala i-choroid plexus cysts kwi-ultrasound yakho, kufanele uxoxe ngalokhu okutholayo nodokotela wakho noma umeluleki wezakhi zofuzo ukuze ubone ukuthi iyiphi ingozi yakho futhi uxoxe nezinye izinketho zokuhlola uma kufanelekile.
