I-CT Angiogram yokwazi kahle ngemithambo yegazi yakho! Singaxoxa ngalokhu?

Ngezinye izikhathi odokotela bethu kudingeka bahlolisise imithambo yegazi engaphakathi emizimbeni yethu. Ukuze sibe neqiniso, ukubona ukuthi kukhona yini inkinga ngaphakathi kwemithambo yegazi, ukuthi kukhona yini ukuvaleka endaweni ethile, ukuthi kukhona yini ukuvuvukala okuncane njengebhaluni. Yilapho-ke lolu vivinyo olukhethekile olubizwa ngokuthi i-CT Angiogram lusisiza khona. Ake sibone ukuthi kuyini lokhu, kwenziwa kanjani, nokuthi kungani kudingeka?

Iyini i-CT Angiogram?

Kalula nje, i-CT angiogram ukuhlolwa okuthatha izithombe ezinemininingwane zemithambo yegazi yakho kanye nezicubu ezizungezile. Kufana nesithombe, kodwa kucace kakhulu. Lokhu kuhlolwa kuvame ukwenziwa ukuhlola ukuvaleka noma ukuncipha kwemithambo yegazi enikeza igazi enhliziyweni yakho, ebizwa ngokuthi imithambo yenhliziyo, noma lokho odokotela abakubiza ngokuthi isifo semithambo yenhliziyo . Ngenxa yalesi sizathu, ngezinye izikhathi kubizwa ngokuthi i-coronary CT angiogram, noma i-CCTA.

Yiziphi ezinye izifo ezisetshenziswa yi-CT angiogram ukuxilonga?

Le CT angiogram isetshenziselwa ukuthola izinto eziningi, hhayi nje imithambo yegazi yenhliziyo. Cabanga ngalezi zimo:

• I-Aneurysm: Lokhu kwenzeka lapho umthambo wegazi, isibonelo i-aorta yakho noma umthambo wegazi ebuchosheni bakho, uvuvukala ngendlela engavamile, njengebhaluni.
• Ukuhlukaniswa kwe-aorta: Lokhu kwenzeka lapho kuba nokudabuka kwengqimba engaphakathi yodonga lwe-aorta yakho.
• Ukukhubazeka kwemithambo yegazi: Lesi yisimo lapho imithambo yegazi nemithambo yegazi kuxhumene khona, ikakhulukazi ezindaweni ezifana nobuchopho.
• Isifo semithambo ye-carotid: Ukuvaleka okubangelwa ukugcwala kwamafutha (i-plaque) emithanjeni ethwala igazi liye ebuchosheni bakho.
• Isifo semithambo yegazi engaphandle: Isimo lapho i-plaque inqwabelana khona emithanjeni yegazi emilenzeni noma ezingalweni zakho.
• I-Pulmonary embolism: I-blood clot ehlala emaphashini.
• Ukuhlukaniswa kwemithambo yenhliziyo okuzenzekelayo (SCAD): Ukudabuka noma ukuhlukana okungazelelwe odongeni lomthambo wenhliziyo enhliziyweni.
• Ukulimala okubuhlungu: Lapho into ebukhali ishaya isifuba sakho, intamo, noma ikhanda, okubangela umonakalo emithanjeni yegazi.

Akukhona lokho kuphela, kodwa ngezinye izikhathi udokotela wakho usebenzisa i-CT angiogram ukuhlela kusengaphambili ukuhlinzwa noma ezinye izinqubo zezokwelapha. Isibonelo, kungakusiza ukuthi ubheke imithambo yakho yenhliziyo ngaphambi kokufaka esikhundleni se-valve yenhliziyo, ukuhlinzwa kwe-heart bypass, noma ukubekwa kwe-stent.

"Ngobuchwepheshe, i-CT angiogram iyisithombe esivela kulolu vivinyo. I-CT angiography iyindlela esetshenziswayo ukuthatha lezi zithombe. Kodwa njengoba sikhuluma, zombili zisetshenziselwa isivivinyo osifunayo. Abanye abantu basibiza nangokuthi i-CTA ngamafuphi."

Isebenza kanjani i-CT angiography?

Ubuwazi ukuthi ngisho ne-CT scan ejwayelekile ingathatha izithombe ezinemininingwane, ezinobukhulu obuthathu (3D) zangaphakathi kwemizimba yethu? Lokho kungenxa yokuthi i-scanner ithatha amakhulu ezithombe ezinobukhulu obubili (2D), eziyisicaba. Ikhompyutha bese ihlanganisa zonke lezi zithombe ukuze idale izithombe ze-3D ezisezingeni eliphezulu. Kodwa-ke, umehluko omkhulu phakathi kwe-CT scan kanye ne-CT angiography ukusetshenziswa kwedayi yokuhlukanisa .

Le ndlela ye-CT scan, ehlanganiswe nezinto ezikhanyisa ukukhanya, yenza imithambo yegazi yakho ibonakale sengathi 'ikhanyisiwe'. Udokotela angajikelezisa lesi sithombe se-3D kuzo zonke izinhlangothi. Kufana nokubamba imodeli encane yomthambo wegazi wakho esandleni sakhe. Lokhu kumvumela ukuthi abone ingxenye ngayinye yomthambo wegazi ngezindlela ezahlukene, athole noma yiziphi izinkinga, futhi ahlele ukwelashwa.

I-CT angiography ayihlaseli kakhulu futhi inezingozi ezimbalwa kune-angiography yendabuko. Ku-angiogram yendabuko, ithubhu elincane elibizwa ngokuthi i-catheter lifakwa emthanjeni wegazi lakho bese liqondiswa endaweni ehlolwayo. I-CT angiogram ayidingi i-catheter. Kodwa-ke, kuye ngokuthi uneminyaka yakho kanye nezinye izimo zezokwelapha, ungase ungabi umuntu ofanele i-CT angiogram. Kuleso simo, kungase kudingeke ukuthi wenze inqubo yendabuko ye-angiography ehlaseli kakhulu okukhulunywe ngayo ngaphambili.

Kufanele uzilungiselele kanjani ngaphambi kwalolu vivinyo?

Udokotela oncome ukuthi wenze i-CT angiogram uzokutshela ukuthi uzilungiselele kanjani. Ngokuvamile, kuzodingeka utshele udokotela okulandelayo:

• Cishe yonke imithi oyithathayo njengamanje.
• Umlando wakho ophelele wezokwelapha, okuhlanganisa nesifo senhliziyo, izinkinga zezinso, kanye nokungezwani komzimba.
• Wake waba nokusabela kokungezwani komzimba nodayi wokwehlukanisa owawusetshenziswa esivivinyweni ngaphambili?
• Kungakhathaliseki ukuthi ukhulelwe noma ungumama oncelisayo .

Udokotela uzokunikeza imiyalelo ethile okufanele uyilandele. Lokhu kungafaka phakathi izinto ezifana nalezi:

• Mangaki amahora okufanele ngizile ukudla ukuze ngihlolwe, okungukuthi, ngingadli noma ngiphuze lutho?
• Ingabe udinga ukuyeka ukuthatha noma yimiphi imithi ovame ukuyithatha ngaphambi kokuhlolwa?

Uma uza ukuzohlolwa, uzonikezwa ingubo yasesibhedlela ozoyigqoka. Kuzodingeka futhi ukhumule noma yibuphi ubucwebe begolide noma besiliva obugqokile, ngoba bungase buphazamise ukuhlolwa.

Yini ongayilindela ngesikhathi se-CT angiogram?

I-CT angiography ivame ukushesha futhi ayinabuhlungu . Kodwa-ke, i-catheter ye-IV, ithubhu elincane, ifakwa emthanjeni ongalweni yakho. Uvukile futhi awukho ngaphansi kwe-anesthesia. Uzolala etafuleni lokuhlolwa. Leli thebula liyindandatho enkulu eyindilinga, njengedonathi, ehambahamba ngaphakathi. Awuvalelwe ngokuphelele, njengoba ubungazivalela ngesikhathi sokuhlolwa kwe-MRI.

Udinga ukuthula kakhulu ngesikhathi sokuhlolwa ukuze isithwebuli sikwazi ukuthola izithombe ezinhle. Umuntu oqeqeshwe ngokukhethekile obizwa ngokuthi i-Radiologic Technologist uzokwenza ukuhlolwa kwakho. Uzochaza isinyathelo ngasinye futhi akutshele ukuthi wenzeni (isibonelo, ukuthi kufanele ubambe umoya isikhathi esingakanani). Nakhu okuvame ukwenzeka:

• Uzophoqwa ukuba ulale etafuleni lokuhlolwa.
• Kuzokusiza ukuthi uhlale ukhululekile. Ungase ukwazi ukusebenzisa imicamelo noma amabhande ukuze uhlale endaweni eyodwa.
• Kuzofakwa i-IV emthanjeni wakho ukuze ikunike idayi yokungafani. Lokhu kuvame ukuba sengalweni noma esinqeni sakho. I-IV izohlala endaweni yayo kuze kube yilapho izithombe zithathwa. Ungase uzizwe ufudumele kancane njengoba idayi ingena. Lokhu kuvamile, ungakhathazeki.
• Uma ukuhlolwa kuwukuthi kubhekwe imithambo yakho yenhliziyo, udokotela uzonamathisela ama-patches amancane (ama-EKG leads) esifubeni sakho. Lokhu kuvumela udokotela ukuthi athathe izithombe ezihambisana nesikhathi sokushaya kwenhliziyo yakho.
• Uma konke sekulungile, uchwepheshe uzoya ekamelweni elihlukile. Uzokwazi ukukubona nokukhuluma nawe ngohlelo lwe-intercom.
• Ithebula lokuhlolwa lihamba liye phambili nangaphakathi ngaphakathi kwendandatho efana ne-donut yesikena. Isikena sithatha amakhulu ezithombe ngalesi sikhathi. Ungase uzwe umsindo omncane wokubhonga noma wokuchofoza.
• Uchwepheshe uzokutshela ukuthi kufanele ubambe umoya wakho nini nokuthi kufanele uhlale unganyakazi nini. Ngisho nokunyakaza okuncane kakhulu kungathinta ikhwalithi yezithombe.
• Ngemva kokuthathwa kwezithombe ezanele, i-IV iyasuswa bese kufakwa ibhandishi elincane phezu kwendawo. Uzosizwa futhi ukuthi uvuke etafuleni. Ngemuva kwalokho ukuhlolwa kuyaphela.

Uzoba segumbini lokuhlolwa cishe imizuzu engama-20 kuya kwengama-60, okuhlanganisa nesikhathi sokulungiselela. Uzoba se-scanner umzuzu owodwa noma emibili kuphela. Kuzophela ngokushesha okukhulu. Kodwa-ke, udokotela kungase kudingeke ahlole i-scanner izikhathi ezingaphezu kwesisodwa ukuze athole zonke izithombe azidingayo.

Ingabe kukhona okungalungile nge-CT angiogram?

Kuye ngezidingo zakho kanye nokukhathazeka kwakho, kungase kube nezinkinga ezithile nge-CT angiography. Lokhu kufaka phakathi:

• Ukusetshenziswa kwedayi yokuhlukanisa: Lokhu akuyona inkinga kubantu abaningi. Kodwa-ke, ngezinye izikhathi ungaba nokusabela kokungezwani komzimba naledayi. Uma uke wakwenza lokhu ngaphambili, udokotela wakho angakunika umuthi wokuphuza ngaphambi kokuhlolwa noma ancome ukuhlolwa okuhlukile.
