Ukuskena okukhethekile ukuze ufunde ngenhliziyo yakho! (I-Cardiac Computed Tomography - I-CT Scan) Ake sixoxe ngakho?

Namuhla sizokhuluma nge-scan ekhethekile engakukhombisa ulwazi oluningi mayelana nenhliziyo yakho. Ibizwa ngokuthi i-cardiac `CT` scan (Cardiac Computed Tomography - CT scan). Mhlawumbe udokotela wakho ukutshelile ukuthi wenze lokhu, noma uke wezwa ngakho ndawana thize. Ngakho ake sibheke ukuthi kuyini, kwenziwa kanjani, okudingeka ukwazi ngaphambi kokuba ukuthole, kanye nezinzuzo nezingozi.

Kuyini ukuhlolwa kwe-CT kwenhliziyo?

Kalula nje, i-CT scan yenhliziyo uhlobo olukhethekile lokuhlolwa kwe-X-ray olusebenzisa imisebe eminingi ye-X-ray evela ezindleleni ezahlukene ukukhiqiza izithombe ezicacile nezinobukhulu obuthathu zenhliziyo yakho, imithambo emikhulu exhuma kuyo, kanye nezicubu ezizungezile.

Odokotela basebenzisa ubuchwepheshe bamuva be-CT ukwenza lokhu kuskena kwe-'Cardiac CT'. Ngezinye izikhathi, kufakwa uketshezi olukhethekile (i-intravenous (IV) contrast / dye) emthanjeni wakho. Lokhu kuvumela isakhiwo senhliziyo kanye nemithambo yegazi exhunywe kuyo ukuthi kubonakale ngokucacile. Le ndlela yokuskena enezicucu eziningi ivumela odokotela ukuthola izithombe zekhwalithi ephezulu kakhulu, ezinezilinganiso ezintathu zenhliziyo yakho ehambayo kanye nemithambo yegazi emikhulu.

Yini engatholakala nge-CT scan yenhliziyo?

Udokotela wakho angathola ukuqonda okungcono kwezinto eziningi ngenhliziyo yakho kulokhu kuskena. Isibonelo:

• Isimo semithambo yenhliziyo enikeza igazi enhliziyweni yakho.
• Indlela amakamelo enhliziyo, imisipha yenhliziyo, kanye nama-valve enhliziyo asebenza ngayo.
• Uhlobo lwemithambo yamaphaphu .
• Kungakhathaliseki ukuthi kunenkinga nge -aorta yesifuba futhi ngezinye izikhathi i-aorta yesisu .
• Isikhwama esivikela inhliziyo (i-pericardium) .

Ngenxa yokuthi konke lokhu kungabonakala ngokucacile kulesi sithwebuli, kuzoba usizo olukhulu kudokotela ukwenza isinqumo esihle mayelana nempilo yenhliziyo yakho.

Kudingeka nini ukuhlolwa kwe-CT yenhliziyo?

I-CT scan yenhliziyo inganikeza idatha enemininingwane necacile kunezinye izivivinyo zezithombe. Kunezizathu eziningana zokuthi kungani udokotela wakho engase acele lokhu kuskena. Ake sibheke ukuthi ziyini:

• Thola ukuthi yini ebangela ubuhlungu besifuba sakho noma ukuphelelwa umoya.
• Hlola imithambo yenhliziyo yakho ukuthi i-calcium noma i-plaque inqwabelene , iyancipha, noma ivimbekile.
• Hlola ukusebenza kwama-valve enhliziyo yakho.
• Hlola noma yiziphi izinkinga nge-aorta yakho, njenge- aneurysms noma ukuqhekeka kwemithambo yegazi .
• Ukuhlinzwa kwenhliziyo okuvulekile nomaHlela ukuhlinzwa kwenhliziyo okungangenisi kakhulu/okuyirobhothi.
• Hlela izinqubo ze-transcatheter/percutaneous valve .
• Hlela izinqubo zokususa i-arrhythmia ngenxa yokuphazamiseka kwesigqi senhliziyo .
• Hlola izinkinga ezingase zenzeke ngemva kokuhlinzwa noma ukwelashwa okunjalo.
• Hlola ukuthi unenkinga yenhliziyo ozalwa nayo .
• Thola ukuthi kukhona yini isimila noma inqwaba enhliziyweni noma eduze kwayo nokuthi iyini.
• Hlola isikhwama esizungeze inhliziyo (i-pericardium) ukuze ubone ukuthi uketshezi luqongelela (`uketshezi`) noma i-calcium deposits (`i-calcification`).

Cabanga nje, umalume wakho uhlala ehlushwa yizinhlungu zesifuba, futhi odokotela abakwazi ukuthola ukuthi yini ngempela ebangela lokhu. Ngesikhathi esinjengalesi, i-'CT' scan inganikeza ulwazi oluningi oluwusizo.

Ubani owenza ukuhlolwa kwe-CT yenhliziyo?

Esikhathini esiningi, udokotela wakho wenhliziyo uzoncoma lokhu kuskena kwe-CT yenhliziyo. Kodwa-ke, kunethimba elihlukile lezempilo endaweni lapho kwenziwa khona ukuskena ukuze likusize. Lawa:

• Ochwepheshe: Laba ngabantu abasebenzisa i-CT scanner futhi bathole izithombe.
• Abahlengikazi: Uma kudingeka, abahlengikazi bazofaka umugqa we-'IV' emthanjeni engalweni yakho bese bekunikeza imithi.
• Odokotela: Odokotela baqapha ukuskena, bahlaziye izithombe, bese benikeza umbiko (`chaza ukuskena`).

Ukuze uthole lokhu kuskena, kufanele uye esibhedlela noma endaweni ekhethekile 'yezithombe zezokwelapha'.

Isebenza kanjani i-CT scan yenhliziyo?

Kulula kakhulu. Njengoba ulele embhedeni wesithwebuli, umsebe we-X-ray uyajikeleza nxazonke zakho. Kodwa awushayi emzimbeni wakho. Ungase uzwe umsindo omncane wokubhonga noma wokuchofoza njengoba umshini usebenza. Ikhompyutha ihlanganisa lezi zithombe zokuskena ukuze idale isithombe senhliziyo yakho esinobukhulu obuthathu (3D).

Uyini umehluko phakathi kwe-MRI yenhliziyo kanye ne-CT yenhliziyo?

Kungenzeka ukuthi uke wezwa ngokuhlolwa kwe-MRI yenhliziyo . Kokubili i-MRI yenhliziyo kanye ne-CT yenhliziyo kungaveza izithombe ezinemininingwane zenhliziyo, kodwa kunezinhlobo ezimbalwa zomehluko phakathi kwalezi zivivinyo ezimbili. Ake sibheke ukuthi ziyini.

• Uma ungena ngaphakathi komshini, umshini we-CT uvulekile kakhulu kunomshini we-MRI. Lokhu kusho ukuthi abanye abantu bazizwa bengaphansi kokuxineka uma bengaphakathi komshini we-MRI.
• Ukuskena kwe-MRI kuthatha isikhathi eside kune-CT scan.
• I-CT scan isebenzisa imisebe ye-X-ray , kodwa i-MRI ayisebenzisi imisebe.
• Umshini we-CT uthule kakhulu kunomshini we-MRI.
• Uma unikezwa i-contrast medium, i-CT scan isebenzisa i-contrast medium ene-iodine , kanti i-MRI isebenzisa i-contrast medium esekelwe ku-gadolinium .

Ngakho-ke, udokotela onquma ukuthi yikuphi ukuskena okufanele kakhulu kuwe.

Ngingalungiselela kanjani lolu vivinyo?

Kufanele ulandele imiyalelo kadokotela wakho ngqo ngosuku olwandulela kanye nangosuku lokuhlolwa kwe-CT yenhliziyo yakho, mayelana nokuthi yini okufanele uyidle futhi uyiphuze, kanye nemithi okufanele uyeke ukuyisebenzisa.

Mayelana nokudla neziphuzo

• Ngosuku lokuhlolwa, ungadli lutho amahora amane kuya kwayisithupha ngaphambi kwesikhathi sakho esihleliwe. Ungaphuza amanzi kuphela.
• Ungaphuzi noma yiziphi iziphuzo ezine-caffeine ngosuku olwandulela noma ngosuku lokuhlolwa. Lokhu kusho ukuthi akufanele uphuze ikhofi, itiye, noma iziphuzo ezinikeza amandla.
• Ungasebenzisi amaphilisi okunika amandla noma amaphilisi okunciphisa umzimba ngosuku olwandulela noma ngosuku lokuhlolwa. Uma unemibuzo ngalokhu, buza udokotela wakho.

Mayelana nemithi

• Uma ungumuntu ozizwa ekhathazekile ezindaweni ezixinene, buza udokotela wakho ngomuthi ongakugcina uzolile ngesikhathi sokuhlolwa.
• Yazisa udokotela wakho ngayo yonke imithi oyithathayo, ngisho nemithi engabhalwanga ngudokotela.
• Ungathathi i-Sildenafil (Viagra® noma i-Revatio®) noma imithi efanayo ngosuku olwandulela noma ngosuku lokuhlolwa, njengoba lokhu kungase kuhlangane nemithi ozoyinikwa ngesikhathi sokuhlolwa. Buza udokotela wakho ngalokhu futhi.
• Uma unesifo sikashukela , buza udokotela wakho ukuthi ungayishintsha kanjani imithi yakho ngosuku lokuhlolwa. Uma ucabanga ukuthi ushukela wakho wegazi uphansi, tshela udokotela wakho ngokushesha.

Yini ongayilindela ngosuku lokuhlolwa?

Ngaphambi kokuhlolwa kwe-CT yenhliziyo yakho, udokotela wakho uzofuna ukwazi ngalezi zinto:

• Ukhulelwe?
• Ingabe une-allergy ku -iodine kanye/noma i-shellfish , noma eminye imithi?
• Ingabe okwamanje uthola ukwelashwa ngemisebe ?
• Uma uneminyaka engaphezu kwengu-60 ubudala , noma uke waba nezinkinga zezinso esikhathini esidlule, kungadingeka ukuthi uhlolwe igazi ukuze kuhlolwe ukusebenza kwezinso zakho ngaphambi kokuba unikezwe uketshezi lokuhlukanisa.

Ukulungiselela ukuhlolwa kwe-CT

• Khumula ubucwebe bakho ubushiye ekhaya.
• Izinketho ezikhethekile ozinikezwe yisibhedlelaKufanele ugqoke ingubo yasesibhedlela.
• Mhlawumbe udokotela angakunika umuthi onciphisa ukushaya kwenhliziyo yakho .
• Uma unikezwa uketshezi olushintsha umbala (oludayi), umhlengikazi uzofaka umugqa we-IV emthanjeni engalweni yakho. Lolu ketshezi yilona olwenza imithambo yegazi nenhliziyo yakho kubonakale ngokucacile ezithombeni zeskeni.
• Uzolaliswa embhedeni okhethekile, bese umbhede uthuthelwa kancane kancane endaweni evulekile ephakathi kwe-CT scanner.
• Udokotela uzohlanza cishe izindawo ezintathu zesifuba sakho bese efaka ama-electrode patches amancane, anamathelayo kuzo. Ukuqinisekisa ukuthi la ma-electrode anamathela kahle, kungadingeka ukuthi uchebe ezinye zezinwele kuleyo ndawo yesifuba sakho.
• Lawa ma-electrode axhunywe kwi-monitor ye-electrocardiogram (EKG) , eqopha umsebenzi kagesi wenhliziyo yakho ngesikhathi sokuhlolwa.
• Uzocelwa ukuba ulale embhedeni wesikena izingalo zakho zingaphezu kwekhanda lakho kuze kube yilapho isivivinyo siphelile. Ikhanda lakho nemilenze yakho kuzoba ngaphandle kwesikena.

Okubaluleke kakhulu: Kubaluleke kakhulu ukuhlala unganyakazi phakathi nalesi sikhathi nokulandela imiyalelo ngokucophelela. Kulapho-ke kuphela lapho uzokwazi ukuthola khona izithombe ezicacile.

Kwenzekani ngesikhathi sokuhlolwa?

Ukuskena kwe-CT yenhliziyo okugcwele kungathatha imizuzu ephakathi kuka-30 no-60 , okuhlanganisa nesikhathi sokulungiselela. Kodwa-ke, ukuskena kwe-CT uqobo kuthatha isikhathi eside, cishe imizuzu eyi-10 okungenani .

• Uzozwa isithwebuli esimise okwedonathi singena embhedeni olele kuwo.
• Uma unikezwa uketshezi oluhlukanisayo, umhlinzeki wezempilo uzolufaka nge-IV line yakho. Kujwayelekile ukuzwa umuzwa ofudumele kancane njengoba uketshezi luhamba emzimbeni wakho. Abanye abantu bangase babe nokunambitheka kwensimbi emlonyeni wabo imizuzwana embalwa.
• Ukuze uthole izithombe ezicacile, kubaluleke kakhulu ukuthi uhlale unganyakazi futhi ulandele imiyalelo ngqo .

Kwenzekani ngemva kokuhlolwa?

Ngemva kokuba udokotela eqinisekisile ukuthi banazo zonke izithombe abazidingayo, uzosusa umugqa wakho we-IV. Ngemuva kwalokho ungashintsha bese uya ekhaya.

Ngemva kokuhlolwa, ungenza imisebenzi yakho evamile bese udla futhi uphuza. Kodwa-ke, uma uphuze umuthi wokudambisa, kuzodingeka othile eze akuyise ekhaya.

Udokotela wakho uzokhuluma nawe ngemiphumela yokuhlolwa ngalolo suku noma ezinsukwini ezimbalwa.

Ingabe zikhona izingozi ngalolu vivinyo?

Ukuskena kwe-CT kuyinqubo enobungozi obuphansi . Kodwa-ke, abanye abantu bangase babe nezinkinga ezincane ngoketshezi oluhlukanisayo noma ezinye izinto ezisetshenziswe esivivinyweni.

I-ejenti yokuqhathanisa / udayi

• Akuvamile ukuthi abanye abantu babe nokusabela okungekuhle kuketshezi oluhlukanisayo (oluvame ukuqukethe i-iodine). Abanye abantu bangase babe nokulunywa, isicanucanu, ukuthimula, noma ukuqubuka kwesikhumba ngemva kokujova uketshezi. Lezi zimpawu zivame ukuphela ngaphandle kokwelashwa. Kodwa-ke, zingalawulwa ngama -antihistamine, ama-steroids, kanye nama-histamine blockers .
• Akuvamile kakhulu ukuthi kube nokusabela okukhulu kokungezwani komzimba (ukusabela kwe-anaphylactic) . Kungabangela ubunzima bokuphefumula. Lokhu kungaba yingozi empilweni, ngakho-ke ukwelashwa okusheshayo kanye nemithi kuyadingeka ukulawula lezi zimpawu.
• Uma unesifo sikashukela noma sezinso , ungase ucelwe ukuba uphuze uketshezi olwengeziwe ngemva kokuskena ukuze usize ekukhipheni i-iodine emzimbeni wakho.
• Njengoba indlela yokuhlukanisa esetshenziswa kwi-cardiac CT scan ingadlulela obisini lwakho lwebele , uma uncelisa, kungumqondo omuhle ukukhama ubisi lwebele ngaphambi kokuskena. Ungabe usupha ingane yakho lolo bisi usuku olulodwa noma ezimbili ngemva kokuskena.

Imisebe

Ama-CT scanner asebenzisa ama-X-ray. Kunengozi encane kakhulu yomdlavuza ngenxa yale misebe ngokuhamba kwesikhathi. Ukuze uphephe, ukuchayeka kwakho emisebeni kugcinwa kuncane kakhulu. Kodwa-ke, ama-X-ray angaba yingozi embungwini osakhula, ngakho-ke lokhu kuhlolwa akukhuthazwa uma ukhulelwe . Uma kudingeka, udokotela wakho uzokwenza amalungiselelo okuvikela ingane yakho.

Imithi yokwehlisa izinga lokushaya kwenhliziyo

Uma unikezwe umuthi wokunciphisa izinga lokushaya kwenhliziyo yakho ngesikhathi sokuhlolwa, noma uma unesifo esifana ne -asthma, ukwehluleka kwenhliziyo, noma isifo samaphaphu esingamahlalakhona (i-COPD) , ungase ube nobunzima bokuphefumula ngesikhathi sokuhlolwa. Kubaluleke kakhulu ukutshela udokotela wakho uma unanoma yisiphi salezi zimo.

Iyini imiphumela? Kusho ukuthini lokho?

Kungaba nezinhlobo ezimbili zemiphumela ngemva kokuskena: imiphumela evamile kanye nemiphumela engavamile.

Imiphumela evamile

• Inhliziyo yakho nemithambo yegazi kubukeka kujwayelekile .
• Isilinganiso sakho se-calcium singu-zero (`0`). Lokho kusho ukuthi awunaso isifo semithambo yenhliziyo , futhi usengozini encane yokuba nesifo senhliziyo.

Imiphumela engavamile

• Kukhona ama-fatty deposits (i-plaque) kanye nokuncipha (i-stenosis) emithanjeni yenhliziyo.
• Ukuba ne-calcium score ephezulu kusho ukuthi une -coronary atherosclerosis .
• Inani le-calcium elingu- 100 noma ngaphansi libonisa izimpawu ezincane zesifo semithambo yenhliziyo.
• Uma ingaphezu kuka-400 , lokhu kubonisa izimpawu ezisakazekile zesifo semithambo yenhliziyo.
• Uma iphakathi kuka-100 no-400 , kunezici zezinga eliphakathi nendawo.
• Ngokuvamile, izinga lakho le-calcium linikezwa njengesilinganiso sephesenti , esikutshela ukuthi umi kuphi uma uqhathaniswa nabanye abantu abaneminyaka yakho, ubulili, kanye nobuzwe bakho abaye bathatha isivivinyo.
• Umsebenzi wenhliziyo noma ama-valve awasebenzi kahle .
• Isifo senhliziyo - ukunqwabelana koketshezi esikhwameni esizungeze inhliziyo (`i-effusion`) kanye nokuvuvukala kwe-pericardium (`i-pericarditis`).
• Kukhona isimila noma inqwaba .
• Kunenkinga yenhliziyo yokuzalwa nayo.
• Umthambo wegazi ukhulisiwe (i-aneurysm) , unesicanucanu (ukuqhekeka) , noma uncishisiwe (i-stenosis/i-coarctation) .

Udokotela wakho uzokuchazela kahle le miphumela.

Kufanele ngimshayele nini udokotela?

Uma uzizwa sengathi usabela kuketshezi oluhlukile noma umuthi owunikiwe ngesikhathi sokuhlolwa, noma uma ungakayitholi imiphumela ye-cardiac CT scan yakho ngemva kwezinsuku ezimbalwa, shayela udokotela wakho.

Izinto ezibaluleke kakhulu okufanele uzikhumbule (Umyalezo Wokuya Ekhaya)

Ungesabi ukuskena kwe-CT yenhliziyo noma umshini we-CT. Lokhu ukuhlolwa okungahlaseli okunikeza udokotela wakho ulwazi oluningi olubalulekile mayelana nokuthi kwenzekani enhliziyweni yakho kanye nezakhiwo zayo ezizungezile.

Ukuze uthole imiphumela emihle kakhulu, landela imiyalelo kadokotela wakho mayelana nokudla nokuphuza ngaphambi kokuhlolwa. Futhi, qiniseka ukuthi uhlala uthule futhi ubambe umoya wakho ngesikhathi sokuhlolwa.

Lokhu kuhlolwa kungakutshela okuningi ngempilo yenhliziyo yakho, ngakho ungangabazi ukukwenza uma kudingeka. Khuluma nodokotela wakho nganoma yimiphi imibuzo noma ukukhathazeka ongase ube nakho.
