Kaviri aortic arch

Kaviri aortic arch chimiro chisina kujairika cheaorta, tsinga hombe inotakura ropa kubva pamoyo ichienda kune wese muviri. Iri idambudziko rekuzvarwa naro, zvinoreva kuti riripo pakuzvarwa.

Double aortic arch inzira yakajairika yeboka rehurema hunokanganisa kukura kweaorta mudumbu. Kukanganisa uku kunokonzeresa kuumbwa kusingaenzanisike kunonzi mhete yevascular (denderedzwa reropa tsinga).

Kazhinji, aorta inokura kubva kune imwe yezvidimbu zvakamonyoroka zvinyama (maberere). Sezvo vacheche vanokura muchibereko, maberere anopatsanuka kuita mativi akati wandei. Muviri unotyora mamwe emaberere, nepo mamwe achiumba tsinga. Aorta inowanzo gadzirwa ibhendi rimwe rinosiya moyo richienda kuruboshwe.

Mune kaviri aortic arch, mamwe maberere aifanira kunge akanyangarika achiripo pakuzvarwa kuwedzera kune yakajairika arch. Vacheche vane aortic arch yakapetwa vane aorta iyo inogadzirwa nemidziyo miviri pane imwe.Izvo zvikamu zviviri kune aorta zvine tutsinga tudiki twunobva pavari. Nekuda kweizvozvo, matavi maviri anotenderera achimanikidza pasi pahwipi uye chubhu (esophagus) inotakura chikafu kubva pamuromo kuenda mudumbu.

Iyo mbiri aortic arch inogona kuitika mune zvimwe zvekuzvarwa kwemoyo kukanganisa, kusanganisira:

• Tetralogy yekunyepedzera
• Truncus arteriosus
• Shanduko yetsinga huru
• Ventricular septal kuremara

Double aortic arch isingawanzoitika. Vascular mhete dzinoumba mashoma muzana ezvese matambudziko ekuberekwa emoyo. Pakati peizvi, inopfuura hafu inokonzerwa nekaortort arch. Mamiriro acho anoitika zvakaenzana muvanhurume nevanhukadzi. Inowanzo kuve mune vanhu vane zvimwe chromosome zvisizvo.

Nekuti zviratidzo zvekaviri aortic arch zvinowanzo kuve zvakapfava, dambudziko rinogona kunge risingawanikwe kudzamara mwana ave nemakore mashoma ekuberekwa.

Iyo mbiri aortic arch inogona kumanikidza pane trachea uye esophagus, zvichitungamira kumatambudziko kufema uye kumedza. Kuomarara kwezviratidzo zvinoenderana nekuti yakawanda sei aortic arch iri kumanikidza pane izvi zvivakwa.

Zviratidzo zvekufema zvinosanganisira:

• Yakakwira-yakadzika ruzha panguva yekufema (stridor)
• Kufema zvine ruzha
• Anodzokororwa mabayo
• Kushungurudza

Zviratidzo zvekudya zvinogona kusanganisira:

• Choking
• Kunetseka kudya uye kumedza
• Kusvipa

Zviratidzo zvinogona kutungamira mupi wekuchengetedza hutano kufungidzira kaviri aortic arch. Mimwe bvunzo inozodikanwa kuti isimbise kuongororwa.

Iyi miedzo inotevera inogona kubatsira kuongorora kaviri aortic arch:

• Chest x-ray
• Zviratidzo zvinogadzira mifananidzo yemuchinjikwa-yemuviri (CT kana MRI scan)
• Ultrasound kuongororwa kwemoyo (echocardiography)
• X-ray uchishandisa chinhu chinoratidzira esophagus (barium swallow)

Kuvhiya kunogona kuitwa kugadzirisa kaviri aortic arch. Chiremba anovhiya anosunga pabazi diki uye anoripatsanura kubva kubazi hombe. Ipapo chiremba anovhara magumo eorta nezvisungo. Izvi zvinoderedza kumanikidza kune esophagus uye windpipe.

Vazhinji vana vanonzwa zvirinani mushure mekuvhiyiwa, kunyangwe vamwe vanogona kuramba vaine zviratidzo zvekufema kwenguva yakati mushure mekugadziriswa kwekuvhiya. Izvi zvinowanzoitika nekuda kwekushomeka kwetrachea nekuda kwekumanikidzwa kwazviri isati yagadziriswa kuvhiya.

Muzviitiko zvisingawanzoitika, kana iyo arch ichimanikidza pasi zvakanyanya munzira yemhepo, mwana anogona kuve nekufema kwakanyanya kunetseka kunotungamira kurufu.

Zvinetso zvinogona kusanganisira:

• Kutadza kubudirira
• Zvirwere zvekufema
• Kupfeka kureba kwekumusoro kwesophagus (esophageal erosion) uye windpipe
• Hazviwanzoitika, kubatana kusingaenzanisike pakati peiyo esophagus uye aorta (aortoesophageal fistula)

Fonera waunopa kana kacheche kako kane zviratidzo zvekaviri aortic arch.

Iko hakuna inozivikanwa nzira yekudzivirira iyi mamiriro.
