CT angiography - mikono ndi miyendo

CT angiography imaphatikiza CT scan ndi jakisoni wa utoto. Njira imeneyi imatha kupanga zithunzi zamitsempha yamagazi m'manja kapena m'miyendo. CT imayimira computed tomography.

Mudzagona pa tebulo laling'ono lomwe limalowa pakati pa chojambulira cha CT.

Mukakhala mkati mwa sikani, makina a x-ray azungulira mozungulira. Makina amakono "ozungulira" amatha kuchita mayeso osayima.

Kakompyuta imapanga zithunzi zingapo za m'thupi, zotchedwa magawo. Zithunzi izi zitha kusungidwa, kuwonedwa pa polojekiti, kapena kusindikizidwa pafilimu. Ma modelo amthupi mmbali zitatu atha kupangidwa ndikuwonjezera magawo palimodzi.

Muyenera kukhala chete pakamayesa mayeso, chifukwa mayendedwe amawasokoneza zithunzi. Muyenera kugwira mpweya wanu kwakanthawi kochepa.

Kuwunika kumangotenga mphindi 5 zokha.

Mayeso ena amafuna utoto wapadera, wotchedwa kusiyanasiyana, kuti ubayike m'thupi lanu mayeso asanayesedwe. Kusiyanitsa kumathandizira madera ena kuwonekera bwino pama x-ray.

• Kusiyanitsa kumatha kuperekedwa kudzera mumitsempha (IV) m'manja mwanu kapena m'manja. Ngati kusiyanitsa kumagwiritsidwa ntchito, mungapemphedwenso kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanayesedwe.
• Lolani wothandizira zaumoyo wanu adziwe ngati mudachitapo kanthu posiyanitsa. Mungafunike kumwa mankhwala musanayezedwe kuti mupewe vutoli.
• Musanalandire kusiyana, uzani omwe akukuthandizani ngati mumamwa mankhwala a shuga metformin (Glucophage). Muyenera kuchita zina ngati mukumwa mankhwalawa.

Kusiyanaku kumatha kukulitsa mavuto amachitidwe a impso mwa anthu omwe ali ndi impso zosagwira bwino ntchito. Lankhulani ndi omwe amakupatsani ngati muli ndi vuto la impso.

Kulemera kwambiri kumatha kuwononga ziwalo zogwirira ntchito za sikani. Ngati mulemera makilogalamu opitilira 300 (135 kilograms), lankhulani ndi dokotala wanu za kuchepa thupi musanayezedwe.

Muyenera kuchotsa zodzikongoletsera ndikuvala chovala chachipatala pakamayesedwa CT.

Anthu ena sangakhale omasuka kugona patebulo lolimba.

Kusiyanitsa komwe kumaperekedwa kudzera mu IV kumatha kuyambitsa:

• Kumverera pang'ono
• Kukoma kwachitsulo mkamwa mwako
• Kutentha kwa thupi lanu

Maganizo amenewa ndi achilendo ndipo nthawi zambiri amatha pakangopita masekondi ochepa.

Mungafunike kuyesedwaku ngati muli ndi zizindikilo za chotupa chamagazi chothina kapena chotsekedwa m'manja, manja, miyendo, kapena mapazi.

Mayesowo amathanso kuchitidwa kuti mupeze:

• Kukulitsa modabwitsa kapena kubaluni kwa gawo la mtsempha wamagazi (aneurysm)
• Magazi
• Kutupa kapena kutupa kwa mitsempha yamagazi (vasculitis)
• Kupweteka kwa mwendo poyenda kapena kuchita masewera olimbitsa thupi (kulongosola)

Zotsatira zimawonedwa ngati zabwinobwino ngati palibe zovuta zowoneka.

Zotsatira zosazolowereka zimachitika makamaka chifukwa cha kuchepa ndi kuuma kwa mitsempha m'manja kapena miyendo kuchokera pakapangidwe kazitsulo m'makoma amitsempha.

X-ray imatha kuwonetsa kutsekeka kwa zotengera zoyambitsidwa ndi:

• Kukulitsa modabwitsa kapena kuwerengera gawo la mtsempha wamagazi (aneurysm)
• Kuundana kwamagazi
• Matenda ena amitsempha

Zotsatira zachilendo zitha kukhalanso chifukwa cha:

• Kutupa kwa mitsempha yamagazi
• Kuvulala pamitsempha yamagazi
• Matenda a Buerger (thromboangiitis obliterans), matenda osowa m'mitsempha ya m'manja ndi mapazi
  

Zowopsa pazowunikira za CT ndi izi:

• Chiwonetsero cha radiation
• Matupi awo akusiyanitsa utoto
• Kuwonongeka kwa impso kuchokera ku utoto wosiyanitsa

Makina a CT amapereka ma radiation ambiri kuposa ma x-ray wamba. Kukhala ndi ma x-ray ambiri kapena ma CT scan pakapita nthawi kumatha kuwonjezera chiopsezo cha khansa. Komabe, chiwopsezo chojambulidwa kamodzi ndichaching'ono. Inu ndi wothandizira wanu muyenera kukambirana za chiopsezo ichi poyerekeza ndi phindu la kuzindikira molondola vutoli. Makina ambiri amakono amagwiritsa ntchito njira zochepa poyerekeza ndi ma radiation.

Lolani wothandizira wanu adziwe ngati munayamba mwadwalapo utoto wosiyanitsa ndi jakisoni.

• Mtundu wofala kwambiri umakhala ndi ayodini. Ngati muli ndi vuto la ayodini, mutha kukhala ndi nseru kapena kusanza, kuyetsemula, kuyabwa, kapena ming'oma mukapeza kusiyana kotere.
• Ngati mukufuna kukhala ndi kusiyana kotereku, omwe amakupatsani akhoza kukupatsani ma antihistamine (monga Benadryl) kapena steroids musanayesedwe.
• Impso zimathandiza kuchotsa ayodini m'thupi. Mungafunike madzi owonjezera pambuyo pa mayeso kuti muthane ndi ayodini ngati muli ndi matenda a impso kapena matenda ashuga.

Nthawi zambiri, utoto umatha kuyambitsa vuto linalake lotchedwa anaphylaxis. Izi zitha kupha moyo. Dziwitsani operekera pompopompo ngati mukuvutika kupuma panthawi yoyesa. Zitsulo zofufuzira zidazo zili ndi intakomu ndi okamba nkhani kuti omvera azikumvani nthawi zonse.
