I thinlungah kawngkhar te tak te i nei em? (Patent Foramen Ovale - PFO) chungchang hi han sawi ila!

I thinlung, a nih loh leh thinlung chung lam pindan pahnih inkarah hian pian hnua awm reng thei tur kawngkhar te tak te a nei thei tih i hre ngai em? He thu hi mi tam takin an hriat chuan mak an ti hle. Mahse, a dik a ni. Hetiang dinhmun hi Patent Foramen Ovale emaw (PFO) emaw an ti a. Lungngai suh, awlsam takin, i hriatthiam theih dan tur angin kan sawi dawn a ni.

PFO chu eng nge ni? A awlsam zawngin i hrethiam ang u

A awlsam zawngin, patent foramen ovale (PFO) hi i thinlung chunglam pindan pahnih, dinglam atrium leh veilam atrium inkar a inhawng te tak te, khuhna ang maia inhawng a ni. Tunah chuan kan nu pum chhunga kan awm vek lai hian he hawnna, foramen ovale an tih hi a awm tih han ngaihtuah teh. A pawimawh hle. Mahse a tlangpuiin, kan pian hnuah a khar thin. PFO chu pian hnua a khar loh chuan a ni. "Patent" tih thumal hi "open" tihna a ni.

A tam zawkah chuan PFO nei te hian symptom an nei lo va, enkawl an ngai lo. Mahse, a tlem hle a, harsatna thenkhat, stroke ang chi hi PFO nen hian a inzawm thei a ni.

Engvangin nge he foramen ovale hi a pawimawh? Nausen lai hian eng nge thleng?

Nausen pum chhunga nausen, nausen chuan a lung chu oxygen tamna thisen lak nan a hmang lo. Chu ai chuan he oxygen tamna thisen hi nu hnen atangin nausen (placenta) kaltlangin, umbilical cord zawhin a lo chhuak zawk a ni. Hei hi foramen ovale hian a ti a, naute dinglam atrium atanga umbilical cord atanga oxygen tamna thisen chu veilam atrium lam pan nghal a ni.

Chuta tang chuan chu thisen chu naute thinlung veilam lamah a kal a, naute thluak leh taksa peng pawimawh dangte hnenah oxygen a pe chhuak a ni. Mechanism mak tak mai a ni lawm ni?

Naute a pian hnuah, a mah chauha thawk a tan chuan thisen chu lungah a kal a, oxygen a la thei a ni. Chutih lai chuan he foramen ovale'' hi a khar tlangpui. Tichuan oxygen nei thisen chu thinlung veilam lamah a kal a, chuta tang chuan taksa pum puiah pump chhuah a ni.

Tuin nge PFO siam thei? Engtiang chiahin nge a hluar?

Dik tak chuan PFO hian tu pawh a nghawng thei a, mipa leh hmeichhia, hnam leh vun rawng pawh thliar lovin. Mahse, pawl thenkhatah chuan a tam zawk:
