I-CT angiography - isifuba

I-CT angiography ihlanganisa ukuskena kwe-CT nomjovo wedayi. Le ndlela ikwazi ukudala izithombe zemithambo yegazi esifubeni nasesiswini esingaphezulu. I-CT imele i-computed tomography.

Uzocelwa ukuba ulale etafuleni elincane elingena phakathi kwesithwebuli se-CT.

Ngenkathi ungaphakathi kwesithwebuli, ugongolo lomshini lwe-x-ray luzungeza wena.

Ikhompyutha idala izithombe ezihlukene eziningi zendawo yomzimba, ezibizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Amamodeli amathathu-ntathu endawo yesifuba angakhiwa ngokufaka izingcezu ndawonye.

Kufanele uthule ngesikhathi sokuhlolwa, ngoba ukunyakaza kubangela izithombe ezifiphalisiwe. Ungatshelwa ukuthi ubambe umoya wakho isikhathi esifushane.

Ukuskena okuphelele ngokuvamile kuthatha imizuzu embalwa kuphela. Ama-scanner amasha angakwazi ukufanekisela wonke umzimba wakho, ikhanda nozwane, ngemizuzwana engaphansi kwengu-30.

Izivivinyo ezithile zidinga udayi okhethekile, obizwa ngokuqhathanisa, ukulethwa emzimbeni ngaphambi kokuqala kokuhlolwa. Umehluko usiza izindawo ezithile ukuthi zibonakale kangcono kuma-x-ray.

• Umehluko unganikezwa ngomthambo (IV) osesandleni sakho noma engalweni. Uma kusetshenziswa umehluko, ungacelwa futhi ukuthi ungadli noma uphuze noma yini amahora amane kuya kwayisithupha ngaphambi kokuhlolwa.
• Yazisa umhlinzeki wakho wezokunakekelwa kwempilo uma ngabe uke waba nokusabela kokungafani. Ungahle udinge ukuthatha imishanguzo ngaphambi kokuhlolwa ukuze uyithole ngokuphepha.
• Ngaphambi kokuthola umehluko, tshela umhlinzeki wakho uma uthatha imishanguzo yesifo sikashukela i-metformin (Glucophage). Ungadinga ukuthatha ezinye izinyathelo zokuqapha.

Umehluko ungadala izinkinga zezinso kubantu abanezinso ezingasebenzi kahle. Khuluma nomhlinzeki wakho uma unomlando wezinkinga zezinso.

Isisindo esiningi kakhulu singalimaza isithwebuli. Uma unesisindo esingaphezu kwamakhilogremu angama-300 (135 kilograms), khuluma nomhlinzeki wakho ngomkhawulo wesisindo ngaphambi kokuhlolwa.

Uzocelwa ukuthi ususe ubucwebe futhi ugqoke ingubo yasesibhedlela ngesikhathi kufundwa.

Ama-x-ray akhiqizwa yi-CT scan awanabuhlungu. Abanye abantu bangase bangakhululeki ngokulala etafuleni eliqinile.

Uma uqhathanisa ngokusebenzisa umthambo, ungahle ube:

• Umuzwa ovuthayo omncane
• Ukunambitheka kwensimbi emlonyeni wakho
• Ukufudumala okufudumele komzimba wakho

Lokhu kujwayelekile futhi kuvame ukuphela ngemizuzwana embalwa.

I-angiogram yesifuba se-CT ingenziwa:

• Ngezimpawu eziphakamisa amahlule egazi emaphashini, njengobuhlungu besifuba, ukuphefumula okusheshayo, noma ukuphefumula okuncane
• Ngemuva kokulimala kwesifuba noma ukuhlukumezeka
• Ngaphambi kokuhlinzwa emaphashini noma esifubeni
• Ukufuna indawo engaba khona ukufaka ipayipi le-hemodialysis
• Ngokuvuvukala kobuso noma izingalo ezingaphezulu ezingachazeki
• Ukubheka ukukhubazeka okusolwayo kwe-aorta noma eminye imithambo yegazi esifubeni
• Ukubheka i-balloon dilation yomthambo (aneurysm)
• Ukubheka izinyembezi emthanjeni (ukuhlukaniswa)

Imiphumela ibhekwa njengejwayelekile uma kungabonwa zinkinga.

Isifuba i-CT singakhombisa ukuphazamiseka okuningi kwenhliziyo, amaphaphu, noma indawo yesifuba, kufaka phakathi:

• Ukuvaleka okusolwayo kwe-vena cava ephakeme: Lo mthambo omkhulu uhambisa igazi elisuka engxenyeni engenhla yomzimba liye enhliziyweni.
• Ama-clot egazi emaphashini.
• Ukungajwayelekile kwemithambo yegazi emaphashini noma esifubeni, njenge-aortic arch syndrome.
• I-aortic aneurysm (endaweni yesifuba).
• Ukuncipha kwengxenye yomthambo omkhulu ophuma enhliziyweni (aorta).
• Izinyembezi odongeni lomthambo (ukuhlukaniswa).
• Ukuvuvukala kwezindonga zemithambo yegazi (vasculitis).

Izingozi zokuhlolwa kwe-CT zifaka:

• Ukuvezwa yimisebe
• Ukusabela okweqile ekuqhathaniseni udayi
• Ukulimala kwezinso kudayi wokuqhathanisa

Izikena ze-CT zisebenzisa imisebe eminingi kunama-x-ray avamile. Ukuba nama-x-ray amaningi noma ama-CT scan ngokuhamba kwesikhathi kungakhuphula ingozi yokuba nomdlavuza. Noma kunjalo, ingozi evela kunoma yikuphi ukuskena okukodwa incane. Wena nomhlinzeki wakho kufanele nilinganise le ngozi ngezinzuzo zokuthola ukuxilongwa okulungile kwenkinga yezokwelapha. Ama-scanner amaningi anamuhla asebenzisa amasu okusebenzisa imisebe emincane.

Abanye abantu banokungezwani komzimba nokuqhathanisa udayi. Yazisa umhlinzeki wakho uma ngabe uke waba nokungezwani komzimba nodayi wokuqhathanisa ojojowe.

• Uhlobo oluvame kakhulu lokungafani olunikezwe emthanjeni luqukethe iodine. Uma une-iodine yokungezwani komzimba, ungahle ube nesicanucanu noma uhlanze, uthimule, ulume, noma isifuba uma uthola lolu hlobo lokungafani.
• Uma kufanele unikezwe umehluko onjalo, umhlinzeki wakho angakunika ama-antihistamine (njengeBenadryl) kanye / noma ama-steroids ngaphambi kokuhlolwa.
• Izinso zisiza ukususa i-iodine emzimbeni. Labo abanesifo sezinso noma isifo sikashukela kungadingeka bathole uketshezi oluthe xaxa ngemuva kokuhlolwa ukusiza ukukhipha iodine emzimbeni.

Imvamisa, idayi ingadala ukusabela okweqile okusongela impilo okubizwa nge-anaphylaxis. Uma unenkinga yokuphefumula ngesikhathi sokuhlolwa, kufanele wazise opharetha besithwebuli ngokushesha. Ama-scanner eza ne-intercom nezipikha, ngakho-ke umuntu angakuzwa ngaso sonke isikhathi.
