Ukuhlolwa kwe-ultrasound yentloko yesisu, kwiseshoni yesibini neyesithathu yokuhlola, ingqalelo ihlala ihlawulwa kwisakhiwo sobuchopho kunye nobukhulu be-ventricles yengqondo.
I-Ventriculomegaly ye-ventricles engxenyeni ebusweni - yintoni na?
Ngokuqhelekileyo kukho i-ventricles 4 yengqondo. Kubunzima bezinto ezimhlophe zengqondo zimbini zazo - i-ventricles engxenyeni yeengqondo, ngasinye ngasinye esinepondo, yangemva nangaphezulu. Ngoncedo lwengqungquthela ye-interventricular, ixhuma kwi-ventricle yesithathu, kwaye idibanisa umbhobho wamanzi wengqondo kwi-ventricle yesine ephantsi kwe-rhomboid fossa. Okwesine, kwakhona, ixhunyiwe kumsele ongundoqo womgca wesipelini. Le yinkqubo yeempahla ezixhunyiwe kunye notywala. Ngokuqhelekileyo, ubungakanani bee-ventricles zangasese zengqondo ziqikelelwa, ubungakanani bungafanelekanga budlule kwi-10 mm kwinqanaba leentsimbi. Ukwandiswa kwee-ventricles zeengqondo kuthiwa yi-ventriculomegaly.
I-Ventriculomegaly e-fetus - izizathu
Ukwandiswa kwee-ventricles zengqondo, okokuqala, kungabangela ukuphuhliswa kwe-system ye-nervous system (CNS). I-vice ingaba yodwa (yodwa inkqubo ye-nervous), okanye idibaniswe nezinye iimeko ezingalunganga zeenkqubo kunye neenkqubo, njengokuba zihlala zikhona ngezifo ze-chromosomal.
Enye imbangela eqhelekileyo ye-ventriculomegaly yintsholongwane kunye neentsholongwane ezincinci zikamama. Ingozi kakhulu yintsholongwane ye-cytomegalovirus kunye ne- toxoplasmosis , nangona nayiphi na intsholongwane okanye i-microbe ingabangela ukungaphumeleli kokuphuhliswa kwengqondo, i-ventriculomegaly kunye ne-hydrocephalus. Izizathu ezinokwenzeka ze-ventriculomegaly zibandakanya umonakalo kumama kunye nomntwana.
Ukuxilongwa kwe-fetal ventriculomegaly
Ngokuchasene ne-fetus hydrocephalus, i-ventriculomegaly iyancipha i-ventricles yengqondo engaphezu kwe-10 mm, kodwa ingaphantsi kwe-15 mm, ngelixa ubukhulu bomxholo wesisu abukhulanga. Ukufumanisa i-ventriculomegaly nge-ultrasound, ukususela kwiiveki ezili-17. Inokuthi ibe yinto engabonakaliyo (ukunyuka kwesinye i-ventricle okanye enye yeempondo zayo), i-symmetrical isolated without other defects, okanye idibaniswe nezinye izinto ezingalunganga zengqondo kunye nezinye izitho. Ngaphandle kwe-ventriculomegaly, i-chromosomal engafanelekanga, efana ne-Down's syndrome, ivela kwi-15-20%.
I-Ventriculomegaly kwimiphumo yesisu
I-ventriculomegaly ephakathi kwe-fetus enobukhulu be-ventricles engama-15 mm, ngokukodwa xa unyango olufanelekileyo, lungaba nemiphumo emibi. Kodwa ukuba ubungakanani bevolumu bungaphezu kwe-15 mm, i-hydrocephalus yomntwana iqala ukukhula, ngoko imiphumo iyahluka kakhulu - ukususela kwiintsholongwane ze-CNS zokuzalwa.
Ukuqala kwangoko kunye nokwanda ngokukhawuleza kwe-ventriculomegaly kunye nokutshintshwa kwe-hydrocephalus, okubi ngakumbi kwezi zibikezelo. Kwaye phambi kwezinto ezimbi kwezinye izitho, umngcipheko wokuba nomntwana ongaqhelekanga (i-Down syndrome, i-Patau okanye i-Edwards syndrome) iyanda. Ukufa kwesisu somntwana okanye ukufa ngexesha lomsebenzi kunye ne-ventriculomegaly lifikelela kwi-14%. Uphuhliso oluqhelekileyo emva kokubeletha ngaphandle kokuphazamisa i-CNS inokwenzeka kuphela kwi-82% yabantwana abasaphila, kwi-8% yabantwana
I-Ventriculomegaly kwi-fetus - unyango
Unyango lwezokwelapha lwe-ventriculomegaly lujoliswe ekunciphiseni i-edema ye-cerebral kunye nomlinganiselo wamanzi e-ventricles (i-diuretics). Ukuphucula isondlo seengqondo ze-fetal, ama-antihypoxants kunye namavithamini ayalelwe, ngokukodwa iqela le-B.
Ukongeza kwonyango lwamayeza, kunconywa oomama ukuba bachithe ixesha elithile emoyeni omtsha, ukuqeqeshwa ngokomzimba okwenzelwe ukuqinisa imisipha yomgangatho weplavic.
