Nezenhliziyo. ifasitela okusaqanda

Patent foramen ovale enhliziyweni itholakala phakathi Atria. Lena imbobo encane ukuze ukuthuthukiswa embryonic uthatha iqhaza kwegazi fetus. Enkabeni yalo, iwindi okusaqanda enhliziyweni lo mshini oluhambelana bokuphila. Ngenxa yokungasebenzi kwamaphaphu asikho isidingo sokuba ukugeleza emikhulu yegazi kubo, igazi elinomoya-mpilo uthola ezingenzeka embungwini ngokusebenzisa placenta.

Vula imbobo phakathi Atria Bypasses ezincane (yamaphaphu) mbuthano. Le nqubo ibizwa ngokuthi "ekuvaleni." Ngaphezu kwalokho, kunyatheliswa indlela enjalo kunomthelela engena ngokuqondile igazi elinomoya ebuchosheni ngenkuthalo asathuthuka kwesikhathi sombungu.

Ngokuvamile, ovale foramen uvala emva kokuzalwa. Lokhu kungenxa ukunyuka komfutho wegazi (igazi) e ohlangothini lwesobunxele inhliziyo.

Kufanele kuqashelwe ukuthi zonke izingane njalo wazalwa ene foramen patent ovale. Njengoba umkhuba ubonisa, ngokuvamile, kuvulwa ivaliwe ezinyangeni zokuqala. Nokho, mayelana 15-20% eziguli ukusinda kuze kube yiminyaka engamashumi amane nge foramen patent ovale. Le nkomba lihlotshaniswa umehluko isakhiwo emgodini. Iqiniso ukuthi foramen ovale kuyinto ichopho elisezweni inqubo ukuncipha ATRIUM kwesokunxele simboziwe. Ngakho, igazi uvikelwe Ukungena kwi-ATRIUM kwesokudla.

Kodwa kwezinye izimo, elihlobene ne yokucindezeleka okwandayo esifubeni ku isizinda ukucindezeleka ngokomzimba (i sokuzikhulula, sneezing, ukukhwehlela nakwezinye izinkinga) valve liyavuleka. Ukulondolozwa izimbobo evulekile neqhaza kunekwehluleka ezihlelekile izindonga, kanye nobukhulu ewindini okweqanda.

Njengoba kokuma ukukhombisa, kusukela kwesobunxele kuya shunting kwesokudla igazi kusukela ATRIUM kwesokunxele kuya kwesokudla akuyona sihambisane nanoma yimiphi izimpawu ezibonisa khona layo, avuzayo, asymptomatic ngakho. Nale ejection wegazi ohlangothini reverse (kusuka kwesokudla kuya ATRIUM kwesokunxele) kungabangela izimpawu unomphela noma lezivakashi ka cyanosis. Njengomthetho, ngalesi simo sibangelwa ukukhula kwemali esetshenziswa ezimakethe yamaphaphu semithambo ukumelana Umthambo uhlelo ku ngemuva zokuphelelwa umoya isiqephu, umoya, ukukhala, nakwezinye izinkinga. Mayelana ukukhululwa wegazi okungavamile phakathi ATRIUM kwesokunxele, cyanosis unomphela (coloration bluish kwesikhumba futhi nolwelwesi lwamafinyila) zigcinwe kulo engu ezisanda kuzalwa. Eqeda isimo ngemuva kokuqala uhudula nokuncipha Umthambo yamaphaphu.

Iwindi okusaqanda ivaliwe kwesikhathi kungabangela kumiswa ukukhubazeka ahlukahlukene. Ngakho, ukuvalwa kwendawo ekuqaleni ngalesi sifo kungenziwa ephelezelwa ukuthuthukiswa kwesokunxele inhliziyo hypoplasia ekuveliseni eminyangweni yalo.

ifasitela Okusaqanda, anda ubukhulu, kungabangela kumiswa embolism ayindida, ephelezelwa izimpawu lezivakashi ukuhlaselwa (ischemic) noma unhlangothi. Ngokocwaningo olwenziwa, akusho uvala iwindi kukhulisa ematfuba unhlangothi ischemic cishe 40%.

Izibonakaliso khona iwindi evulekile inhliziyo futhi zihlanganisa paroxysmal migraine ikhanda. Namuhla-ke ayikaqondwa kahle indlela yentuthuko isimo ngokumelene isizinda ayivaliwe emgodini. Ezimweni eziningi, okuvela kuyo ubuhlungu ukuchaza microembolization ku thrombi ubuchopho (amahlule ezincane), kanye nethonya izinto kwakhiwa ohlelweni emithanjeni futhi engena ngqo izitsha ingqondo.

Akuvamile ebukhoneni emgodini ovulekile enhliziyweni ingaqala ortodeoksii platipnoe syndrome. Lesi simo libhekene ukwehla ukugcwaliswa (ukugcwaliswa) wegazi mpilo ebangeni ime mpo emzimbeni ephelezelwa iphika.
