Truncus arteriosus

Truncus arteriosus ndi mtundu wosowa wamatenda am'mimba momwe chotengera chamagazi chimodzi (truncus arteriosus) chimachokera kumanjenje kumanja ndi kumanzere, m'malo mwa zotengera ziwiri zabwinobwino (mtsempha wama pulmonary ndi aorta). Amapezeka pakubadwa (matenda obadwa nawo amtima).

Pali mitundu yosiyanasiyana ya truncus arteriosus.

Pazoyenda bwino, mitsempha yam'mapapo imatuluka mu ventricle yolondola ndipo aorta imatuluka mu ventricle yakumanzere, yomwe imasiyana.

Ndi truncus arteriosus, mtsempha umodzi umatuluka m'mitsempha. Nthawi zambiri pamakhala bowo lalikulu pakati pa ma ventricles awiri (vuto lamitsempha yamagetsi). Zotsatira zake, mtundu wamagazi wabuluu (wopanda oxygen) komanso wofiira (wokhala ndi okosijeni).

Ena mwa magazi osakanizikawa amapita m'mapapu, pomwe ena amapita kuthupi lonse. Nthawi zambiri, magazi ambiri kuposa nthawi zonse amatha kupita m'mapapu.

Ngati vutoli silichiritsidwa, mavuto awiri amachitika:

• Kuchuluka kwa magazi m'mapapu kumatha kuyambitsa madzi owonjezera mkati ndi mozungulira iwo. Izi zimapangitsa kuti zikhale zovuta kupuma.
• Ngati sakusamalidwa ndipo magazi amapitilira m'mapapu kwa nthawi yayitali, mitsempha yam'mapapo imawonongeka mpaka kalekale. Popita nthawi, zimakhala zovuta kwambiri kuti mtima uwakakamize magazi. Izi zimatchedwa kuthamanga kwa magazi m'mapapo, komwe kumatha kupha moyo.

Zizindikiro zake ndi izi:

• Khungu labuluu (cyanosis)
• Kukula kwakuchedwa kapena kukula kukulephera
• Kutopa
• Kukonda
• Kudya moperewera
• Kupuma mofulumira (tachypnea)
• Kupuma pang'ono (dyspnea)
• Kukulitsa nsonga zala (kupopera)

Kudandaula kumamveka nthawi zambiri mukamamvetsera pamtima ndi stethoscope.

Mayeso ndi awa:

• ECG
• Zojambulajambula
• X-ray pachifuwa
• Catheterization yamtima
• MRI kapena CT scan pamtima

Kuchita opaleshoni kumafunika kuchiza vutoli. Opaleshoniyo imapanga mitsempha iwiri yosiyana.

Nthawi zambiri, chotengera chamtengo wapatali chimasungidwa monga aorta watsopano. Mitsempha yatsopano yam'mapapo imapangidwa pogwiritsa ntchito minofu yochokera kwina kapena kugwiritsa ntchito chubu chopangidwa ndi anthu. Mitsempha ya m'mapapo ya nthambi imasokonekera pamitsempha yatsopanoyi. Dzenje pakati pa ma ventricles latsekedwa.

Kukonzanso kwathunthu nthawi zambiri kumapereka zotsatira zabwino. Njira ina ingafunike pamene mwanayo akukula, chifukwa mtsempha wam'mimba womangidwanso womwe umagwiritsa ntchito minofu yochokera kwina sikudzakula limodzi ndi mwanayo.

Matenda osachiritsidwa a truncus arteriosus amabweretsa imfa, nthawi zambiri mchaka choyamba cha moyo.

Zovuta zingaphatikizepo:

• Mtima kulephera
• Kuthamanga kwa magazi m'mapapu (kuthamanga kwa magazi)

Itanani wanu wothandizira zaumoyo ngati khanda lanu kapena mwana wanu:

• Amawoneka olema
• Amawoneka wotopa kwambiri kapena kupuma pang'ono
• Samadya bwino
• Zikuwoneka kuti zikukula kapena zikukula bwino

Ngati khungu, milomo, kapena misomali ya misomali ikuwoneka yabuluu kapena ngati mwanayo akuwoneka kuti akupuma movutikira, tengani mwanayo kuchipinda chodzidzimutsa kapena muwonetseni mwanayo mwachangu.

Palibe njira yodziwika yopewera. Kuchiritsidwa msanga kumatha kupewa zovuta zazikulu.

• Kuchita opaleshoni yamtima wa ana - kutulutsa

• Mtima - gawo kupyola pakati
• Truncus arteriosus
