Cardiology. denderedzwa hwindo

Patent foramen ovale mumwoyo riri pakati atria. Uyu duku gomba embryo kukura anotora chikamu mune fetus riparadzirwe. At paro, kuti denderedzwa hwindo iri mumwoyo mashandiro ari adaptive uye vasiri. Nokuda basa iri mapapu havafaniri hombe chokubuda ropa kwavari, yakachena-mupfumi ropa zvikanzwika mudumbu kubudikidza placenta.

Open neburi pakati atria bypasses diki (pulmonary) denderedzwa. Izvi anonzi "Kukunda." Mukuwedzera, riparadzirwe nzira yakadaro zvinobatsira zvakananga kupinda akapfuma ropa kuti uropi vachishingaira kukura embryonic period.

Kazhinji, asi foramen ovale anovhara pashure pokuberekwa. Izvi imhaka cheBP (ropa) ari parutivi mwoyo rworuboshwe.

Zvinofanira kucherechedzwa kuti zvose vanozvarwa nguva dzose pamwe bvumidzwa foramen ovale. kazhinji, sezvo tsika inoratidza pakuvhurwa yapera panguva yokutanga mwedzi. Zvisinei, vanenge 15-20% wevarwere vararame kusvika makore makumi mana ne bvumidzwa foramen ovale. chakarurama iri kusonganirana musiyano sechivako mugomba. Chokwadi chokuti foramen ovale ari kurova-rova riri nedanho zvinoderedza kuruboshwe atrium chinofukidzwa. Saka, ropa riri kutadziswa kupinda munzvimbo zvakanaka atrium.

Asi mune mamwe mamiriro ezvinhu, chokuita yakawedzera kuomesa ari mubhokisi iri pakanyorwa mumuviri mupfungwa (nokuti defecation, sneezing, vangakosora uye nezvimwe zvinetso) vharafu anovhura. Ndichengetedze yakazaruka maburi kubatsira vamwe STRUCTURAL kuremara mu masvingo, uyewo ukuru denderedzwa hwindo.

Sezvo zvakawanika inoratidza, kubva kuruboshwe kuenda kurudyi shunting ropa kubva kuruboshwe atrium ari kurudyi haisi pamwe chero zviratidzo zvayo kuvapo, usabuda, saka asymptomatic. With ejection ichi ropa iri neizvi mirayiridzo (kubva kurudyi kuenda kuruboshwe atrium) anogona kukonzera zvachose kana zvinopfuura zviratidzo cyanosis. Kazhinji, mamiriro uyu anokonzerwa kuwedzera pulmonary vascular nemishonga tsinga nenyika nechekumashure kufema chiitiko, mweya, chemai, uye nezvimwe zvinonetsa. Nezvokumutswa nokubudiswa zvemamiriro ropa mukati akasiya atrium, zvachose cyanosis (rinokwanisa kucheneruka dziberekane ganda uye mucous membranes) inogona ainawo achangozvarwa zera. Hakubvisi mamiriro atanga zvuva zvinoderedza pulmonary tsinga.

The denderedzwa hwindo yapera nguva isati yakwana kunogona kukonzera paumbwe urema siyana. Saka, mangwanani pakazovharwa chirwere chinogona pamwe kukura akasiya mwoyo hypoplasia iri kwaita madhipatimendi ayo.

Oval hwindo, akawedzera kukura, zvinogona kukonzera paumbwe gangaidzo embolism, achiperekedzwa zviratidzo zvinopfuura kurwiswa (ischemic) kana nevanga. Maererano zvidzidzo, haavhariri hwindo kunowedzera ndingangokuvara ischemic sitiroko vanenge 40%.

Zviratidzo pamberi yakazaruka hwindo mumwoyo zvinosanganisirawo paroxysmal nomusoro migraine. Nhasi zvinonzi zvichiri havaratidzi kunzwisisa mashandiro okukura ari mamiriro tikafunga asina kuvharwa mugomba. Kazhinji, panowanikwa marwadzo dzinotsanangura microembolization muuropi thrombi (clots duku ropa), uye simba zvinhu achiumbwa negadziriro mutsinga uye rakapinza zvakananga kunyika uropi midziyo.

Kashoma pamberi rakavhurika buri mwoyo unogona kuva ortodeoksii platipnoe syndrome. Ichi chirwere kunoratidzwa vasanyanye saturation (saturation) ropa okisijeni iri wehunyambiri nzvimbo mumuviri kusanganisira kupfupika mweya.
