Patent foramen ovale

Patent foramen ovale (PFO) ndi bowo pakati pa atria yakumanzere ndi kumanja (zipinda zapamwamba) zamtima. Dzenje limakhalapo mwa aliyense asanabadwe, koma nthawi zambiri limatseka atangobadwa kumene. PFO ndiyomwe dzenje limatchedwa ikalephera kutseka mwachilengedwe mwana akabadwa.

A foramen ovale amalola magazi kuyenda m'mapapu. Mapapu a mwana sagwiritsidwa ntchito akamakula m'mimba, choncho dzenjelo silimayambitsa mavuto m'mwana wosabadwa.

Kutsegula kumayenera kutsekedwa atangobadwa, koma nthawi zina sikutseka. Pafupifupi munthu 1 mwa anayi, kutsegula sikutseka. Ngati satseka, amatchedwa PFO.

Zomwe zimayambitsa PFO sizikudziwika. Palibe zodziwika pangozi. Ikhoza kupezeka limodzi ndi zovuta zina zamtima monga atrial septal aneurysms kapena netiweki ya Chiari.

Makanda omwe ali ndi PFO ndipo alibe vuto lina lililonse lamtima alibe zisonyezo. Akuluakulu ena omwe ali ndi PFO amadwalanso mutu waching'alang'ala.

Echocardiogram itha kuchitidwa kuti mupeze PFO. Ngati PFO sichikuwoneka mosavuta, katswiri wa zamagetsi amatha "kuyesa kuwira." Saline solution (madzi amchere) amalowetsedwa mthupi momwe katswiri wamatenda amayang'ana mtima pa chowunika cha ultrasound (echocardiogram). Ngati PFO ilipo, thovu laling'ono limawoneka likuyenda kuchokera kumanja kupita kumanzere kwa mtima.

Matendawa samathandizidwa pokhapokha ngati pali mavuto ena amtima, zizindikilo, kapena ngati munthuyo wadwala sitiroko yoyambitsidwa ndi magazi kuubongo.

Chithandizo nthawi zambiri chimafunikira njira yotchedwa catheterization yamtima, yomwe imagwiridwa ndi katswiri wamtima wophunzitsa kuti asindikize PFO. Opaleshoni ya mtima yotseguka sigwiritsidwanso ntchito kuthana ndi vutoli pokhapokha ngati akuchitanso opaleshoni ina.

Khanda lomwe lilibe zofooka zina pamtima limakhala ndi thanzi labwino komanso kukhala ndi moyo wathanzi.

Pokhapokha pali zolakwika zina, palibe zovuta kuchokera ku PFO nthawi zambiri.

Anthu ena amatha kupuma movutikira komanso magazi ochepa akamakhala kapena kuyimirira. Izi zimatchedwa platypnea-orthodeoxia. Izi ndizochepa.

Nthawi zambiri, anthu omwe ali ndi ma PFO amatha kukhala ndi vuto linalake (lotchedwa paradoxical thromboembolic stroke). Pogwidwa modzidzimutsa, magazi omwe amatuluka m'mitsempha (nthawi zambiri mitsempha ya mwendo) amatuluka ndikumapita mbali yakumanja kwa mtima. Nthawi zambiri, chovalachi chimapitilira m'mapapu, koma mwa wina yemwe ali ndi PFO, chovalacho chimatha kudutsa pabowo kumanzere kwa mtima. Itha kuponyedwa kuthupi, kupita kuubongo ndikukhazikika pamenepo, kupewa magazi kupita mbali imeneyo ya ubongo (stroke).

Anthu ena atha kumwa mankhwala kuti ateteze magazi.

Itanani yemwe akukuthandizani ngati mwana wanu atembenuka buluu akulira kapena akutuluka m'mimba, amavutika kudyetsa, kapena kuwonetsa kukula.
