CT angiography - chifuwa

CT angiography imaphatikiza CT scan ndi jakisoni wa utoto. Njira imeneyi imatha kupanga zithunzi zamitsempha yamagazi pachifuwa ndi kumtunda. CT imayimira computed tomography.

Mudzafunsidwa kuti mugone patebulo lochepetsetsa lomwe limalowa pakati pa chojambulira cha CT.

Mukakhala mkati mwa sikani, X-ray ya makina imayenda mozungulira inu.

Kakompyuta imapanga zithunzi zingapo za thupi, zotchedwa magawo. Zithunzi izi zitha kusungidwa, kuwonedwa pa polojekiti, kapena kusindikizidwa pafilimu. Mitundu yazithunzi zitatu za m'chifuwa imatha kupangidwa ndikulumikiza magawo palimodzi.

Muyenera kukhala bata pakamayesa, chifukwa mayendedwe amayambitsa zithunzi zolakwika. Mutha kuuzidwa kuti musunge mpweya wanu kwakanthawi kochepa.

Kujambula kwathunthu kumangotenga mphindi zochepa. Makina atsopanowa atha kujambulitsa thupi lanu lonse, kumutu mpaka kumapazi, pasanathe masekondi 30.

Mayeso ena amafuna utoto wapadera, wotchedwa kusiyanasiyana, kuti uperekedwe mthupi mayeso asanayambe. Kusiyanitsa kumathandizira madera ena kuwonekera bwino pa 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 mulandire bwino.
• Musanalandire kusiyana, uzani omwe akukuthandizani ngati mumamwa mankhwala a shuga metformin (Glucophage). Mungafunike kusamala kwambiri.

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 sikani. Ngati mukulemera makilogalamu opitilira 300 (135 kilograms), lankhulani ndi omwe amakupatsirani za malire anu asanayesedwe.

Mudzafunsidwa kuti muchotse zodzikongoletsera ndikuvala chovala chachipatala munthawi ya kafukufukuyu.

Ma x-ray opangidwa ndi CT scan sakhala opweteka. Anthu ena atha kukhala osasangalala pogona patebulo lolimba.

Ngati muli ndi kusiyana pamitsempha, mutha kukhala ndi:

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

Izi si zachilendo ndipo nthawi zambiri zimatha pakangopita masekondi ochepa.

Chifuwa cha CT angiogram chingachitike:

• Kwa zizindikilo zomwe zimafotokoza magazi m'mapapo, monga kupweteka pachifuwa, kupuma mwachangu, kapena kupuma pang'ono
• Pambuyo povulala pachifuwa kapena kuvulala
• Pamaso pa opaleshoni m'mapapo kapena pachifuwa
• Kufufuza tsamba lomwe lingatheke kuyikapo catheter ya hemodialysis
• Kutupa kwa nkhope kapena mikono yakumtunda komwe sikungathe kufotokozedwa
• Kuti muyang'ane vuto lokayikira kubadwa kwa aorta kapena mitsempha ina yamagazi pachifuwa
• Kuyang'ana buluni kutambasula kwamitsempha (aneurysm)
• Kuti muyang'ane misozi mumtsempha (dissection)

Zotsatira zimawonedwa ngati zabwinobwino ngati palibe zovuta zowoneka.

Chifuwa cha CT chitha kuwonetsa zovuta zambiri zamtima, mapapo, kapena chifuwa, kuphatikiza:

• Kutseka komwe kumayembekezereka kwa vena cava wapamwamba: Mitsempha yayikuluyi imasuntha magazi kuchokera kumtunda kwa thupi kupita kumtima.
• Magazi amaundana m'mapapu.
• Zovuta zamitsempha yamagazi m'mapapu kapena pachifuwa, monga aortic arch syndrome.
• Aortic aneurysm (m'chifuwa).
• Kuchepetsa gawo la mtsempha waukulu womwe umatuluka mumtima (aorta).
• Misozi kukhoma kwa mtsempha wamagazi (kutsekeka).
• Kutupa kwamitsempha yamagazi (vasculitis).

Zowopsa pazowunikira za CT ndi izi:

• Kuwonetsedwa ndi radiation
• Thupi lawo siligwirizana ndi utoto wosiyanitsa
• Kuwonongeka kwa impso kuchokera ku utoto wosiyanasiyana

Makina a CT amagwiritsa ntchito radiation kwambiri 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 omwe akukuthandizani muyenera kuyeza izi kuti musapindule ndi kupeza matenda oyenera. Makina ambiri amakono amagwiritsa ntchito njira zochepa poyerekeza ndi ma radiation.

Anthu ena ali ndi chifuwa chosiyanitsa utoto. Lolani wothandizira wanu adziwe ngati munayamba mwadwalapo utoto wosiyanitsa ndi jakisoni.

• Mtundu wofala kwambiri womwe umaperekedwa mumtsinje uli ndi ayodini. Ngati muli ndi vuto la ayodini, mutha kukhala ndi nseru kapena kusanza, kuyetsemula, kuyabwa, kapena ming'oma mukapeza kusiyana kotere.
• Ngati mukuyenera kusiyanitsidwa motere, omwe amakupatsani akhoza kukupatsani ma antihistamine (monga Benadryl) ndi / kapena steroids musanayesedwe.
• Impso zimathandiza kuchotsa ayodini m'thupi. Omwe ali ndi matenda a impso kapena matenda ashuga angafunikire kulandira madzi ena pambuyo poyesedwa kuti athandize ayodini kunja kwa thupi.

Kawirikawiri, utoto ungayambitse matenda omwe amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda. Ngati mukuvutika kupuma panthawi yoyesayo, muyenera kudziwitsa operekera makinawo nthawi yomweyo. Zitsulo zofufuzira zidazo zimabwera ndi intakomu ndi masipika, kuti wina azimvanso nthawi zonse.
