I-CT angiography - isifuba

I-CT angiography idibanisa i-CT scan kunye nenaliti yedayi. Obu buchule buyakwazi ukwenza imifanekiso yemithambo yegazi esifubeni nakwisisu esingaphezulu. I-CT imele i-computed tomography.

Uya kucelwa ukuba ulale kwitafile emxinwa ethe tyaba embindini wesikena se-CT.

Ngelixa ungaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ngeenxa zonke kuwe.

Ikhompyuter yenza imifanekiso eyahlukeneyo yommandla womzimba, obizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezinemilinganiselo emithathu yendawo yesifuba zinokwenziwa ngokudibanisa izilayi kunye.

Kuya kufuneka uthe cwaka ngexesha loviwo, kuba intshukumo ibangela imifanekiso emnyama. Unokuxelelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.

Ukugqitywa kokugqitywa kudla ngokuthatha nje imizuzu embalwa. Izikena ezintsha zinokufanekisela umzimba wakho uphela, intloko neenzwane, kwimizuzwana engaphantsi kwama-30.

Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuba ihanjiswe emzimbeni ngaphambi kovavanyo. Umahluko unceda iindawo ezithile zibonise ngcono kwi-x-reyi.

• Umahluko unokunikwa ngomthambo (IV) osesandleni sakho okanye kwingalo yakho. Ukuba kusetyenziswa umahluko, unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 phambi kovavanyo.
• Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka ukuba uthathe amayeza ngaphambi kovavanyo ukuze ufumane ngokukhuselekileyo.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo okhuseleko.

Umahluko unokubangela iingxaki zeengxaki zezintso kubantu abanezintso ezingasebenzi kakuhle. Thetha nomboneleli wakho ukuba unembali yeengxaki zezintso.

Ubunzima obuninzi bunokonakalisa iskena. Ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (i-135 kilograms), thetha nomboneleli wakho malunga nomda wobunzima ngaphambi kovavanyo.

Uya kucelwa ukuba ususe ubucwebe kwaye unxibe ilokhwe yasesibhedlele ngexesha lofundo.

I-ray-ray eveliswe yi-CT scan ayinabuhlungu. Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Ukuba unomahluko kumthambo, unokuba:

• Imvakalelo encinci yokutsha
• Incasa yentsimbi emlonyeni wakho
• Ukufudumeza okufudumeleyo komzimba wakho

Oku kuqhelekile kwaye kuhlala kuhamba kwimizuzwana embalwa.

Isifuba se-CT angiogram sinokwenziwa:

• Ngeempawu ezithi zicebise amahlwili egazini emiphungeni, afana nentlungu yesifuba, ukuphefumla ngokukhawuleza, okanye ukuphefumla kancinci
• Emva kokulimala kwesifuba okanye ukwenzakala
• Phambi kotyando emiphungeni okanye esifubeni
• Ukujonga indawo enokwenzeka ukufaka i-catheter ye-hemodialysis
• Ukudumba kobuso okanye iingalo ezingasentla ezingenakuchazwa
• Ukujonga isiphene sokukrokrela sokuzalwa se-aorta okanye eminye imithambo yegazi esifubeni
• Ukujonga ibhaluni yokwanda komthambo (aneurysm)
• Ukujonga iinyembezi kwimithambo (dissection)

Iziphumo zithathwa njengeziqhelekileyo ukuba akukho ngxaki zibonwayo.

Isifuba i-CT sinokubonisa iingxaki ezininzi zentliziyo, imiphunga, okanye indawo yesifuba, kubandakanya:

• Ukucinywa okucingelwayo kwe-vena cava ephezulu: Lo mthambo mkhulu uhambisa igazi ukusuka kwisiqingatha somzimba usise entliziyweni.
• Amahlwili egazi emiphungeni.
• Ukungaqheleki kwemithambo yegazi emiphungeni okanye esifubeni, njenge-aortic arch syndrome.
• Aortic aneurysm (kwindawo yesifuba).
• Ukuncitshiswa kwenxalenye yomthambo omkhulu ophuma entliziyweni (aorta).
• Iinyembezi eludongeni lweartery (dissection).
• Ukudumba kweendonga zemithambo yegazi (vasculitis).

Iingozi ze-CT scan zibandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nokwahlula idayi
• Ukonakala kwezintso kwidayi eyahlukileyo

Izikena ze-CT zisebenzisa imitha engaphezulu kwee-ray eziqhelekileyo. Ukuba ne-x-ray okanye i-CT scans ekuhambeni kwexesha kunokunyusa umngcipheko womhlaza. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Wena kunye nomboneleli wakho kufuneka ulinganise lo mngcipheko ngokubhekiselele kwizibonelelo zokufumana ukuxilongwa ngokuchanekileyo kwingxaki yonyango. Uninzi lwabavavanyi bale mihla basebenzisa iindlela zokusebenzisa imitha engaphantsi.

Abanye abantu banesifo sokungafani nedayi. Yazisa umboneleli wakho ukuba ngaba ukhe wafumana into engahambelaniyo nokwahlula idayi.

• Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Ukuba une-iodine ye-allergies, unokuba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye imingxunya xa ufumana olu hlobo lokwahluka.
• Ukuba ngokuqinisekileyo kufuneka unikwe umahluko, umboneleli wakho unokukunika ii-antihistamines (ezinjengeBenadryl) kunye / okanye ii-steroids ngaphambi kovavanyo.
• Izintso zinceda ukususa iodine emzimbeni. Abo banesifo sezintso okanye isifo seswekile banokufuna ukufumana ulwelo olongezelelweyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni.

Ngokuqhelekileyo, idayi inokubangela ukuba ubomi buphendule ngokusongela ubomi obubizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, kuya kufuneka wazise umqhubi weskena kwangoko. Iiskena siza ne-intercom kunye nezithethi, ukuze umntu akuve ngalo lonke ixesha.
