Truncus arteriosus

Truncus arteriosus rudzi rwusingawanzo rwechirwere chemwoyo umo imwe tsinga yeropa (truncus arteriosus) inobuda kubva kurudyi uye kuruboshwe ma ventricles, pachinzvimbo cheyakajairika 2 midziyo (pulmonary artery uye aorta). Iyo iripo pakuzvarwa (congenital moyo chirwere).

Kune mhando dzakasiyana dze truncus arteriosus.

Mukufamba kwese, pulmonary arteri inobuda muiyo kurudyi ventricle uye aorta inobuda kubva kuruboshwe ventricle, ayo akaparadzana kubva kune mumwe nemumwe.

Iine truncus arteriosus, tsinga imwe chete inobuda muma ventricles. Iko kune kazhinji kazhinji zvakare kune hombe hombe pakati pemaviri ma ventricles (ventricular septal chirema). Nekuda kweizvozvo, iro rebhuruu (risina oxygen) uye tsvuku (oxygen-yakafuma) kusanganiswa kweropa.

Imwe yeropa rakavhenganiswa inoenda kumapapu, uye imwe inoenda kune yakasara yemuviri. Kazhinji, kuwanda kweropa kupfuura zvakajairwa kunoguma kwaenda kumapapu.

Kana aya mamiriro asina kurapwa, matambudziko maviri anoitika:

• Kupararira kweropa kwakanyanyisa mumapapu kunogona kukonzera kuwanda kwemvura kuumbika mukati nekuvakomberedza. Izvi zvinoita kuti zvive zvakaoma kufema.
• Kana ikasiiwa isingarapwa uye inopfuura yakajairwa ropa inoyerera ichienda kumapapu kwenguva yakareba, tsinga dzeropa kumapapu dzinokuvara zvachose. Nekufamba kwenguva, zvinova zvakaoma kwazvo kuti moyo umanikidze ropa kwavari. Izvi zvinonzi pulmonary hypertension, inogona kutyisidzira hupenyu.

Zviratidzo zvinosanganisira:

• Ganda reBluish (cyanosis)
• Kunonoka kukura kana kukura kutadza
• Kuneta
• Lethargy
• Kudya zvisina tsarukano
• Kukurumidza kufema (tachypnea)
• Kufema kwekufema (dyspnea)
• Kuwedzera kwemazano emunwe (clubbing)

Kugunun'una kunowanzo nzwika kana uchiteerera kumoyo ne stethoscope.

Miedzo inosanganisira:

• ECG
• Echocardiogram
• Chest x-ray
• Catheterization yemwoyo
• MRI kana CT scan yemoyo

Kuvhiya kunodiwa kurapa mamiriro aya. Kuvhiya kunogadzira maviri akasiyana arteri.

Muzviitiko zvakawanda, truncal ngarava inochengetwa seyorta nyowani. Tsinga nyowani yemapurmoni inogadzirwa uchishandisa nyama kubva kune imwe sosi kana kushandisa chubhu yakagadzirwa nevanhu. Tsinga dzemapurmonary arteri dzakasonerwa kune iyi tsinga nyowani. Buri pakati pemaburi evharoni rakavharwa.

Kugadzirisa kwakazara kazhinji kunopa mibairo yakanaka. Imwe nzira inogona kudikanwa apo mwana anokura, nekuti artery yemapapu yakavakazve iyo inoshandisa nyama kubva kune imwe sosi haizokure pamwe nemwana.

Zviitiko zvisina kurapwa zve truncus arteriosus zvinoguma nerufu, kazhinji mukati megore rekutanga rehupenyu.

Zvinetso zvinogona kusanganisira:

• Kutadza kwemoyo
• Kuwedzera kweropa mumapapu (pulmonary hypertension)

Fonera wako mupi wezvehutano kana mwana wako mucheche kana mwana:

• Inoratidzika lethargic
• Inoonekwa yakanyanya kuneta kana kupfava zvishoma
• Haidyi zvakanaka
• Inoita kunge isiri kukura kana kusimukira zvakajairika

Kana ganda, miromo, kana mibhedha yezvipikiri zvichitaridzika seruvara rwebhuruu kana kana mwana achiita kunge ari kutadza kufema, tora mwana wacho uende naye kuimba yekukurumidzira kana kuti mwana aongororwe nekukasika.

Iko hakuna kunozivikanwa kudzivirira. Kurapa kwekutanga kunogona kudzivirira zvinetso zvakakomba.
