Cardiology. chowulungika zenera

Maluso foramen ovale mu mtima ili pakati atria lapansi. Ichi ndi bowo laling'ono kuti chitukuko embryonic watenga mbali mu makope yoopsa. Pakati pake penipeni, zenera chowulungika mu mtima wa limagwirira ndi dziphunzitsiranso ndi thupi. Chifukwa wongokhala a m'mapapo ndiye palibenso chifukwa otaya lalikulu la magazi kwa iwo, magazi mpweya kulemera afika kwa mwana wosabadwayo kudzera latuluka lapansi.

Open dzenje pakati atria ndi bypasses yaing'ono (m'mapapo mwanga) bwalo. Zimenezi amatchedwa "Kuthana." Komanso, makope ngati njira kumathandiza mwachindunji kulowa magazi chuma ubongo kusiyana mwachangu nthawi embryonic.

Childs, foramen ovale atseka atabadwa. Ichi ndi chifukwa kuthamanga kwa magazi (magazi) mu kumanzere kwa mtima.

Tikumbukenso kuti ana onse zonse anabadwa ndi setifiketi foramen ovale. Monga mmene kumapeto, nthawi zambiri, kutsegula chatsekedwa m'miyezi yoyambirira. Komabe, za 15-20% odwala kupulumuka kwa zaka makumi anai ndi setifiketi foramen ovale. chizindikiro ichi amagwirizana ndi kusintha kapangidwe ka una. chakuti foramen ovale ndi khumudwitsidwa umene uli m'kati kuchepetsa mu atrium kumanzere aphimbidwa. Choncho, mwazi zizipita ku malowedwe mu atrium bwino.

Koma zinthu zina, amagwirizana ndi kuthamanga pamtima pa maziko a maganizo thupi (kwa defecation, sneezing, kutsokomola ndi mavuto ena) vavu chikuyamba. Kuteteza mabowo lotseguka zimathandiza kuti ena zopindika kandalama makoma, komanso kukula kwa zenera chowulungika.

Monga kuzipenya kusonyeza, kuchokera kumanzere kupita kumanja shunting magazi kuchokera atrium kumanzere kupita kumanja si limodzi ndi zizindikiro zikusonyeza kukhalapo kwake, ikudontha, kotero asymptomatic. Ndi ejection izi magazi motsogozedwa n'zosiyana (kuchokera kumanja kwa atrium kumanzere) zingachititse zizindikiro chokhalitsa kapena chosakhalitsa cha cyanosis. Monga ulamuliro, boma amayamba ndi kuwonjezeka mu m'mapapo mwanga mtima dongosolo kukana mtsempha wamagazi pa maziko apnea Zomwe zinachitika, mpweya, kulira, ndi mavuto ena. Mogwirizana ndi kutulutsidwa kwa magazi nthenda mu atrium kumanzere, cyanosis okhazikika (bluish coloration mwa khungu nembanemba mucous) akhoza anakhalabe mu m'badwo akhanda. Kumatha boma pambuyo chiyambi cha kuchepetsa kuukoka mu mtsempha wamagazi m'mapapo mwanga.

Zenera chowulungika chatsekedwa asanakalambe zingachititse mapangidwe zofooka zosiyanasiyana. Choncho, kutsekera oyambirira a matenda akhoza limodzi ndi chitukuko cha kumanzere mtima hypoplasia mu zikamera m'madi- ake.

Chowulungika zenera, kuchuluka kukula, zingachititse mapangidwe embolism paradoxical, limodzi ndi zizindikiro za kufupika kuukira (ischemic) kapena kachigawo. Malinga ndi maphunziro, si kutseka zenera kumawonjezera Mwina wa sitiroko ischemic ndi pafupifupi 40%.

Zizindikiro za pamaso pa zenera Tsegulani mtima mulinso paroxysmal migraine mutu. Lero akadali bwino anamvetsa limagwirira chitukuko cha boma ndi maziko a osati anatseka dzenje. Nthawi zambiri, pakutchulidwa ululu kufotokoza microembolization mu ubongo thrombi (magazi kuundana zing'onozing'ono), ndiponso zochita za zinthu aumbike mwa dongosolo la mitsempha komanso zopweteka mmakutu mwachindunji mu zotengera ubongo.

Kawirikawiri pamaso pa dzenje lotseguka mu mtima angathe ortodeoksii platipnoe syndrome. chikhalidwe ichi amakhala ndi kuchepa machulukitsidwe (machulukitsidwe) mpweya magazi pa malo ofukula mu thupi limodzi ndi kupuma movutikira.
