ptc duab yog dab tsi? Cov duab puas tsis xis nyob?

Coronary artery yog cov hlab ntsha uas muab cov ntshav myocardial, muaj ob ceg, sab laug thiab sab xis, uas qhib ncaj qha rau sab laug thiab sab xis aortic sinus raws li lub hauv paus ntawm lub aorta, uas lawv pib mus rau saum npoo ntawm lub plawv thiab txuas ntxiv mus. mus ceg rau hauv lub siab. Txij li cov ntshav thiab vascular phab ntsa yog sib npaug opaque thiab sib tshooj nrog lub plawv, thaum atherosclerotic plaque los yog stenosis tshwm sim nyob rau hauv vascular lumen, nws tsis tuaj yeem pom hauv X-ray zoo tib yam. Kev xaiv coronary angiography yog ua kom percutaneous puncture ntawm ib qho tshwj xeeb zoo li lub plawv catheter mus rau hauv cov hlab ntsha femoral ntawm qis qis, retrograde raws li descending aorta mus rau hauv paus ntawm ascending aorta. Lub catheter yog muab tso rau ntawm sab laug thiab sab xis coronary artery qhib raws, thiab X-ray cinematography los yog daim kab xev kaw tau ua tib lub sij hawm raws li tus tsim tawm yog txhaj. Ua li no, vascular lumen ntawm tag nrho sab laug lossis sab xis coronary artery thiab nws cov ceg tuaj yeem pom meej meej. Nws tuaj yeem nkag siab seb puas muaj qhov mob stenosis, ua kom pom tseeb ntawm qhov chaw kho mob, thaj tsam, qhov hnyav thiab qhov xwm txheej ntawm phab ntsa vascular, txiav txim siab txog kev kho mob (kev cuam tshuam, kev phais lossis kev kho mob), thiab txiav txim siab cov nyhuv curative. Qhov no yog ib qho kev nyab xeeb thiab txhim khu kev qha kev kuaj mob, uas tau txais ntau thiab ntau dua hauv tsev kho mob thiab tau raug suav tias yog "tus qauv kub" rau kev kuaj mob plawv.
