I-placenta iyilungu lesikhashana elidingekayo elivela ngesikhathi sokukhulelwa. Iqala ukwakha emva kokutshala kweqanda elifakwe emanzini esibelethweni, futhi ngokuvamile le nqubo igcwaliswa ngamasonto angu-16 okukhulelwa. Ngesikhathi sokukhulelwa, i-placenta inikeza ukulethwa kwe-oxygen nezakhi kumntfwana. Ukunqunywa kobukhulu be-placenta ngokusekelwe emiphumeleni yokuhlolwa kwe-ultrasound kunikeza umbono wokuthi usebenza kahle kangakanani nemisebenzi yawo.
I-Placenta Hyperplasia - Izimbangela
Usayizi ojwayelekile we-placenta uchazwa ezincwadini eziningi ezinqamulelayo. Cabanga ngobukhulu obujwayelekile be-placenta amasonto. Ngakho-ke, isibonelo, ubukhulu be-placenta emavikini angu-21, 22 nama-23 wokubeletha kufana no-21, 22 no-23 mm. Emasontweni angama-31 wokubeletha, ubukhulu be-placenta buba yi-31 mm, emavikini angu-32 nama-33, angu-32 no-33 mm, ngokulandelana. Ukukhula kwe-placenta kwenzeka ngaphambi kweviki lama-37 lokukhulelwa bese kufinyelela ku-33.75 mm, emva kwalokho ukukhula kwalo kuyeka, futhi ekupheleni kokukhulelwa, kukhona ukulinganisa okungu-33.25 mm. Ukuqina kwe-placenta noma i-hyperplasia yayo kungaba uphawu lwezinkinga ezihlukahlukene.
Izizathu ze-hyperplasia ye-placenta zifaka:
- isifo sikashukela sinomfazi okhulelwe;
- I-Rhesus-impikiswano (uma owesifazane okhulelwe enesifo esibi se-Rh, kanti ingane isinezinhle);
- izifo ezibangelwa amagciwane (acute ukutheleleka kwesandulela ngculaza, umkhuhlane);
- izifo ezithathelwana ngokocansi (mycoplasma, ureaplasma, chlamydia, toxoplasma, gonorrhea, syphilis);
- i-anemia enamandla, ngokuncipha kwamazinga we-hemoglobin angaphansi kuka-80 g / l.
Ukuxilongwa kwe-hyperplasia ye-placental ne-expansion (intervorsing space) ye-MVP akufanele ukwesatshwe. Ukwandiswa kwe-MVP kwenzeka ukubuyisela imali - ekuphenduleni ukuqina kwe-placenta.
I-Hyperplasia ye-placenta - ukwelashwa
Uma owesifazane ene-placenta ekhulisiwe ehlongozwayo ngesikhathi se-ultrasound, udinga ukuphinda i-ultrasound ngesonto, futhi enze i-dopplerometry (i- doppler yabesifazane abakhulelwe - isifundo sokugeleza kwegazi emgqeni we-umbilical) kanye nesifo se-cardiotocography (sinquma inombolo nenani lezinhlungu zomzimba emntwaneni). Lezi zifundo ziyadingeka ukunquma isimo se-fetus nokuxilongwa ngesikhathi esifanele sokubambezeleka kokuthuthukiswa kwe-intrauterine.
Ngama-hyperplasia okuyi-placental ephazamisekile futhi engekho i-pathology engxenyeni ye-fetus, ukwelashwa kungase kungadingekile. Uma ucwaningo olwengeziwe luqinisekisa ukulibaziseka kokuthuthukiswa komntwana we-fetus kanye ne-hyperplasia ye-placental, owesifazane kufanele abe esibhedlela ukuze aphathe.
Kunconywa ukusebenzisa izidakamizwa ezithuthukisa i-microcirculation ku-placenta (pentoxifylline, trental), izidakamizwa ezihlanza igazi (i-curantil, i-cardiomagnet). Kubalulekile ukusebenzisa izidakamizwa ezithuthukisa i-oxygenation ye-placenta futhi, ngokufanele, i-fetus (actovegin). Umphumela omuhle wokwelapha ubalulekile. Ukusetshenziswa kwe-phospholipids ebalulekile njengezinto zokwakha zamangqamuzana ezivimbela ukubhujiswa kwazo. Ukuphumelela kokwelashwa kuzokwanda uma kunwetshwa ukwelashwa kwevithamini E ne folic acid.
I-Hyperplasia ye-placenta - imiphumela
Ukunyuka kobunzima be-placenta kuholela esimweni esibizwa ngokuthi i-fetoplacental insufficiency,
Ngakho, sibheke izimbangela ezikhona, izindlela zokuxilongwa nokuphathwa kwe-placental hyperplasia. Lezi zifo zokukhulelwa zitholakala kahle ekulungiseni izidakamizwa. Umsebenzi oyinhloko wesifazane okhulelwe ukubhaliswa ngesikhathi esifanele kokubonisana kwabesifazane, kanye nokusetshenziswa kwazo zonke izincomo zesidokotela zokwelashwa nokuxilongwa.
