Tam sim no ib qho ntawm cov kev siv tau zoo tshaj plaws thiab cov cuab yeej siv high-tech siv hauv cov kab mob leeg tshav yog angiography ntawm cerebral hlab ntsha. Qhov no zoo pub rau koj pom tau txhua tus tib neeg lub cev thiab cov hlab ntsha ntawm lub cev loj, yog li tus kws kho mob tuaj yeem ua kom tiav txog qhov muaj ib qho aneurysm, txhaws thiab hlav. Tsis tas li ntawd, feem ntau angiography yog siv los npaj rau kev phais.
Cov kev qhia rau angiography
Cov txheej txheem no yog yuav tsum muaj xws li:
- lub cev mob lub cev tsis ntev, uas cov kev cai no tuaj yeem tiv tsis taus nrog;
- muaj kev tsis xis nyob rau hauv cheeb tsam chaw menyuam yaus;
- kiv taub hau, uas tsis cuam tshuam nrog kev hloov hauv lub cev;
- xeev siab, uas tsis yog los ntawm kev noj mov;
- nquag syncope ;
- mob plawv;
- ua txhaum ntawm kev ntshav siab nyob rau hauv hlav.
Kev mob angiography muaj raws li:
- kev tshawb nrhiav kev kuaj mob;
- limb ischemia;
- qhov nqaij ntuag thiab raug mob ntawm cov hlab ntsha;
- qhov tshwm sim ntawm rethrombosis los yog rov tshwm sim dua.
MRI angiography ntawm cerebral hlab ntsha
Cov txheej txheem no yuav siv cov khoom siv hlau nplaum, uas tso cai rau koj kom tau cov duab zoo tshaj plaws. MR angiography yog siv rau aneurysms ntawm cerebral hlab ntsha, kom paub meej tias cov hav zoov stenosis thiab occlusions. Hom no yog txoj kev nyab xeeb tshaj plaws los muab cov ntaub ntawv qhia txog cov yam ntxwv ntawm cov hlab ntsha, lawv txoj haujlwm thiab cov txheej txheem tshwm sim hauv lawv. Cerebral angiography cia koj tshem tawm qhov kev xav tau sib txawv ntawm tus qauv kom tau cov lus qhia txog cov hlab ntsha ntawm lub hlwb. Txawm li cas los xij, yog hais tias nws yog ib qhov tsim nyog los tshawb xyuas cov qog nqaij hlav, ces kev siv tau yog. Qhov tshwm sim ntawm daim ntawv ntsuam xyuas yog ib daim duab ntawm cov hlab ntsha nrog lawv cov ncauj lus kom ntxaws.
CT angiography ntawm cerebral vessels
Hom no kuj yog siv los ua kev tshawb fawb txog lub xeev ntawm lub hlwb cov hlab ntsha. Nyob rau hauv cov lus nug ntawm daim duab, pom cov duab 3-dimensional tau, uas ua rau nws yooj yim los tsim cov angiographic duab thiab kawm cov kabmob ntawm lub qhov tsim nyog. Nrog rau lub computer txoj kev kuaj angiography, tau cov ntaub ntawv hais txog cov hlab ntsha ntawm lub hlwb kis tau siv cov khoom sib txawv ntawm iodine-uas muaj, uas, thaum kis los ntawm kabmob, tso cai rau koj mus muab cov duab ntxaws tshaj tawm thaum luam roj. Qhov zoo ntawm MSCT (multi-helical computer angiography) yog qhov muaj peev xwm los kawm lub hlwb lub nkoj nrog rau txoj kab uas hla 1 hli thiab muab nws cov duab ntawm txhua lub hauv qhov projections uas tsis siv tau cov kev cai, xws li cranio-caudal.
Qhov kev ntsuam xyuas yog raws li nram no:
- Ua ntej txoj kev pib, ob tug milliliters ntawm qhov sib txawv yog txhaj cov tshuaj tua kab mob mus rau hauv kab mob kom pom lub cev cov tshuaj tiv thaiv.
- Thaum pom tias tsis muaj qhov ua rau tsis haum , nkag mus rau hauv ib txoj leeg ntawm ib qho quav los yog txhuam.
- Tus kws kho mob saib qhov sib txawv ntawm cov hlab ntsha mus ib ntus, ces siv cov duab.
- Tom qab ua cov dluab nyob rau hauv cov kev pab cuam tshwj xeeb, pom cov hlab ntsha hauv nyias qhov txawv.
Contraindications rau angiography ntawm cerebral vessels
Raws li cov txheej txheem tuaj yeem tsim muaj qee qhov teeb meem, cov nram qab no pawg neeg raug txwv tsis pub ua qhov kev soj ntsuam no:
- muaj cov yam tsis zoo ntawm iodine-muaj qhov sib npaug (qhov no kis tau cov khoom xyaw gadolinium);
- nyob rau hauv txoj kev mob siab mob hlwb;
- nrog rau cov kab mob ntawm cov kab mob sab hauv;
- nyob rau hauv cov mob theem ntawm myocardial infarction;
- kev tsim txom los ntawm lub raum tsis ua hauj lwm, vim yog qhov uas nws tsis tuaj yeem tshem tawm qhov sib txawv ntawm lub cev;
- yog muaj teeb meem nrog ntshav coagulability;
- poj niam cev xeeb tub.
