Flow nyob rau hauv cov hlab ntsha ib txwm, uas loj npaum li cas ntawm txoj kab uas hla tshaj cov hlab ntsha, twb qeeb qeeb. Cov leeg yuav tuav cov ntshav ntev dua thiab ntws tsis tau nrawm. Cev xeeb tub los yog noob caj noob ces ua rau muaj teeb meem hauv cov leeg ntau dua li cov hlab ntsha vim qhov tseeb lawv yuav ua rau txhaws ntau dua.
Vim li cas venous thrombosis tshwm sim ntau dua hauv cov hlab ntsha?
(A) Arterial thrombosis tshwm sim nyob rau hauv siab shear flow thaum platelet nplua nuj thrombi tsim nyob ib ncig ntawm ruptured atherosclerotic plaques thiab puas endothelium. (B) Venous thrombosis tshwm sim nyob rau hauv qis shear flow thiab feem ntau nyob ib ncig ntawm cov phab ntsa endothelial tsis zoo.
Vim li cas DVT ntau dua hauv ob txhais ceg?
Yog cov ntshav txav qeeb dhau ntawm koj cov leeg, nws tuaj yeem ua rau cov qe ntshav hu ua txhaws.

Qhov no feem ntau yuav tshwm sim hauv koj txhais ceg, ncej puab, lossis lub plab mog.
Qhov txawv ntawm arterial thiab venous thrombosis yog dab tsi?
Venous thrombosis yog thaum cov ntshav txhaws txhaws cov hlab ntsha. Cov leeg nqa ntshav los ntawm lub cev rov qab mus rau lub plawv. Arterial thrombosis yog thaum cov ntshav txhaws thaiv cov hlab ntsha. Cov hlab ntsha nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau lub cev.
