Ngaloo gama elithi "intlungu ye-hyperechoic" ithetha umfanekiso oqaqambileyo emathunjini ebusana kwi-monitor ye-device ultrasound. Kufuneka kuqatshelwe ukuba i-echogenicity yamathumbu ikhulu kunokuba i-echogenicity yezinye izitho zangaphakathi ezikufutshane nayo. Kwimeko apho ukhanyiso lwamathambo luya kukhanyisa ukukhanya komfanekiso wamathambo, bathetha ngokunyaniseka.
Amathumbu angama-hyperechogenous fetus afunyanwe kwi-0.5% yamatyala kwi-2 trimester yokukhulelwa. Olu hlobo lwesisu luyahlukahluka kumgangatho oqhelekileyo, okanye luyakwazi ukubonwa ukuba umntwana uginya igazi, elingagciniweyo kwaye lihlala kwi-lumen. Kwiimigangatho ezithathayo zokukhulelwa, umgudu we-hyperechoic ubonisa ukuphuhliswa kwe-meconium peritonitis okanye i-ileus ye-meconium, okanye uphawu losulelo lwe-inkukhu.
Iimbangela ze-gutera ye-hyperechoic ebusweni
Ukuba ngethuba lokuhlolwa kwe-ultrasound umntwana ubonisa intlungu ye-hyperechoic, ngoko umama okhuselekileyo akafanele abe nexhala, kuba mhlawumbi le ngxaki yomntwana isenokutshintsha emva kwexesha. Kodwa ungakulibali ukuba u-hyperechoicity unokubonisa:
- izifo ze-chromosomal (i-Down syndrome);
- ukulibazisa ukuphuhliswa kwe-intrauterine;
- usulelo lwe-intrauterine lomntwana.
Kufuneka kukhunjulwe ukuba ukusekwa kwe-hyperechoogenicity akubonakali ngokuthe ngqo ukuba khona kwe-Down syndrome, kodwa bubungqina bokuba mngcipheko wokwanda kwesi sifo. Kule meko, kulungele ukuguqula i-geneticist ukujonga iimphumo zesilingo se-biochemical once again. Kwakhona kuyimfuneko ukuba ihlolwe ngenxa yobungqina be-antibodies kwi-cytomegalovirus, i-virus ye-herpes simplex, i-toxoplasmosis, i-parovirus, i-rubella.
Ukukhuphela ukulibaziseka ekuphuculweni kwe-intrauterine , kuyimfuneko ukujonga ngaphezu koko:
- Ingaba kukho ukubuyela emva kobukhulu beentloko kunye nomzimba wesityalo kwisithuba sokukhulelwa;
- ingaba kukho ukungabikho kwamanzi;
- ingaba ukuhamba kwegazi kwiinqanawa zesisu nomntwana, i-placenta, ayincitshiswa.
Ukuba akukho nenye yeempawu eziqinisekisiweyo, ngoko ukuxilongwa kungabandakanywa, kwaye kuyimfuneko ukuseka enye imbangela ye-hyperechogenicity.
Iziphumo zesisu se-hyperechoic ebusweni
Idata efunyenwe ngabaphandi abahlukeneyo ibonisa ukuba ubukho bendoda ekhulelwe yiyo isiseko sokuhlukanisa ibhinqa elikhulelweyo njengeqela elijongene nobungozi, ekubeni unokuba nomntwana one- cystic fibrosis . Nangona inyaniso yokuba intlungu ye-hyperechoic ingakwazi ukuthetha ngeentlobo ezahlukeneyo zesifo somntwana,
Unyango lwegciwane le-hyperechoic emntwaneni
Kwiimeko zokumiselwa kwe-intestinal hyperechoinality, ukuhlolwa kokuqala kwangaphambi kokubeletha kuqhutyelwe yintokazi, eya kubandakanya ukufundwa kwekaryotype, ukuhlaziywa kwe-ultrasound anatomy, ukubeka esweni imeko yakhe kunye nokuqhuba iimvavanyo zokusuleleka kwintsholongwane. Kuphela emva koko ugqirha unako ukunika loo mfazi iingcebiso eziyimfuneko kunyango kunye nokulawulwa okuqhubekayo kokukhulelwa.
