Cov hlab ntsha ntawm iav (computer tomography angiography) yog ib qho kev tshawb nrhiav uas pom tau tias cov hlab ntsha ntawm cov hlab ntsha (leeg, hlab ntsha) nrog kev ntsuam xyuas tom qab ntawm lawv cov mob thiab qhov xwm txheej ntawm cov ntshav khiav hauv lawv. Tus qauv yog siv cov khoom siv tshwj xeeb - tom qab, uas muaj duab peb sab ntawm cov hlab ntsha yog tsim X-ray thiab tom qab tshuab computer. Cov iav angiography yog non-tus ua, nrog rau kev sib kis tsawg heev.
Cov kev qhia rau CT angiography
Feem ntau cov kab CT-angiography yog siv los kawm txog cov hlab ntsha ntawm cov hlab ntsha, cov hlab ntsha thiab cov hlab ntsha, cov hlab ntsha thiab mob plab, cov hlab ntsha carotid, lub raum cov hlab ntsha, cov hlab ntsha ntawm cov sab nraub qaum. Kev kuaj pom yog qhia kom paub txog kev txawv txav ntawm kev mob plab, lawv cov thrombosis, stenosis thiab obstruction, lwm yam vascular, thiab cov kab mob ntsig. Cov kev mob tshwm sim uas ua rau lub hauv paus rau txoj kev tshawb no yog:
- nquag kiv taub hau , mob taub hau;
- kev xauj ntawm kev nqua;
- deterioration ntawm eyesight, lub rooj sib hais;
- nco tsis tau ;
- los ntshav, thiab lwm yam.
Npaj kom npaj rau CT angiography
Yuav ua rau kom sib txawv ntawm daim duab thiab muab cov duab meej ntawm cov kab mob hauv iav nrog CT angiography, ib tug tshwj xeeb radiopaque tus neeg uas muaj iodine yog nkag tau rau hauv lub cev. Rau qhov no, ib tug cannula thiab ib catheter muab tso rau hauv cov hlab ntsha ulnar, uas yog qhov sib txawv ntawm cov tshuaj yuav raug xa tawm los ntawm lub dispenser ntawm tus nqi. Nyob rau hauv lub neej yav tom ntej, nws yuav tawm los ntawm lub cev los ntawm ob lub raum nyob rau hauv ib txoj kev uas ntuj.
Cov teeb meem thiab cov kev mob tshwm sim ntawm cov txheej txheem mas feem ntau yog siv los ntawm kev siv tus neeg sawv cev sib txawv, uas tuaj yeem ua rau tsis haum cov tshuaj. Tsis tas li ntawd, cov tshuaj siv tau tuaj yeem cuam tshuam qhov kev mob ntawm ob lub raum. Yog li, ua ntej txoj kev kuaj, tus neeg mob yuav tsum tau ua qee yam kev ntsuam xyuas.
