Thrombosis vs Embolism
Thrombosis yog tsim los ntawm cov ntshav txhaws thaum embolism yog ib qho kev kho mob uas tawg tawm me me los ntawm cov hlab ntsha, rog thiab lwm yam tuaj thiab thaiv cov hlab ntsha. Cov xwm txheej no tuaj yeem tshwm sim zoo ib yam yog tias cov hlab ntsha uas thaiv tau zoo ib yam, tab sis cov hlab ntsha thaiv cov hlab ntsha ntawm qhov chaw nqaim thaum embolism tuaj yeem thaiv cov hlab ntsha noj qab haus huv, ib yam nkaus.
Thrombosis yog tsim cov ntshav txhaws. Tom qab cov kab mob platelets sib sau ua ke ntawm qhov chaw ntawm qhov txhab los ua ib qho xoob xoob, cov txheej txheem fibrin hloov cov hlua xoob mus rau hauv cov ntshav txhaws. Fibrin tsim muaj feem cuam tshuam txog kev cuam tshuam thiab ntau yam ntawm cov ntshav txhaws. Muaj ob txoj hauv kev ntawm cov ntshav txhaws; cov intrinsic thiab extrinsic pathways. Ob txoj kev no converge mus rau ib qho kev sib tw, uas ua rau muaj cov ntshav txhaws. Ob txoj hauv kev no muaj qhov tshwm sim zaum kawg uas yog ua kom muaj txiaj ntsig X.
ntshav txhaws - txoj hauv kev hauv lub cev: Thaum pib ntawm txoj kev hauv nruab nrog cev, lub molecule hu ua kininogen activates factor XII. Cov tshuaj tiv thaiv no tshwm sim sab nraud, thaum ntshav los rau hauv cov iav. Hauv lub cev nws pib thaum lub nkoj puas ntsoog nthuav tawm cov hauv paus collagen fibers rau cov txheej txheem colotting. Yam XI thiab IX qhib ua ntu zus. Factor IX khi yam VIII thiab ua kom muaj X.
ntshav txhaws - txoj hauv kev tawm sab nraud: Thaum pib ntawm txoj kev tawm sab nraud, ib qho molecule hu ua cov ntaub so ntswg thromboplastin activates factor VII. Factors IX thiab X tau qhib tom qab. Factor X catalyzes kev hloov pauv ntawm prothrombin rau thrombin. Thrombin activates factor XIII. Cov txiaj ntsig kawg yog kev hloov pauv ntawm fibrinogen rau fibrin. Ib qho fibrin meshwork cov ntaub ntawv nyob ib ncig ntawm cov platelet xoob thiab cov ntaub ntawv tseem ceeb.
Qhov tshwm sim no yog qhov tseem ceeb hauv kev kho mob thaum qhov no tshwm sim hauv cov hlab ntsha nqaim uas muab lub cev. Thaum cov ntsiab lus lipid siab txhawb cov plaque tsim ntawm phab ntsa hlab ntsha, cov hlab ntsha tau nqaim. Thaum muaj kev puas tsuaj nyob rau sab saum toj ntawm cov quav hniav, cov ntshav txhaws nyob rau sab saum toj ntawm cov quav hniav ntxiv cuam tshuam cov ntshav ntawm lub cev. Nov yog qhov tshwm sim hauv plawv nres.
Clotting yog qhov zoo heev vim nws tso tseg los ntawm cov tawv nqaij qhov txhab. Nws kaw ib lub portal uas nyuam qhuav tsim tshiab nkag rau kev kis kab mob. Clotting yog qhov tseem ceeb rau kev ua tiav ntawm cov txheej txheem phais.
Embolism
Embolism yog ib qho mob uas muaj me me los ntawm cov ntshav txhaws, rog, cua, kua amniotic, lossis cov ntaub so ntswg ntawm qhov chaw sib txawv tuaj thiab thaiv cov hlab ntsha. Hauv cov neeg mob uas tau pw hauv txaj lossis immobilized, cov ntshav txhaws tuaj yeem tsim nyob rau hauv cov leeg sib sib zog nqus ntawm ob txhais ceg. Qhov no yog hu ua deep vein thrombosis. Clot embolism tshwm sim thaum emboli los ntawm cov tua thiab thaiv cov hlab ntsha hauv lub ntsws. Fat embolism tuaj yeem tshwm sim qhov twg tom qab tawg, rog globules los ntawm cov pob txha tua mus rau thaiv cov hlab ntsha. Huab cua embolism tshwm sim vim qhov nkag ntawm huab cua mus rau hauv cov hlab ntsha hauv qhov nyiaj uas tsis tuaj yeem nqus tau. Thaum lub sij hawm tus me nyuam, nyob rau hauv sab nraud cephalic version thiab poly-hydramnios, amniotic kua yuav nkag mus rau hauv kev. Placental cov ntaub so ntswg so tawm thiab nkag mus rau hauv niam txoj kev ncig thaum cev xeeb tub hauv feeb. Thaum cev xeeb tub induced hypertension, muaj kev pheej hmoo siab ntawm placental cov ntaub so ntswg embolism.
Qhov txawv ntawm Thrombosis thiab Embolism yog dab tsi?
• Thrombosis yog txhaws tsim thaum embolism tawg tawm me me los ntawm cov hlab ntsha, rog thiab lwm yam.
• Thrombosis thaiv cov hlab ntsha ntawm qhov chaw nqaim thaum emboli tuaj yeem thaiv cov hlab ntsha noj qab haus huv, ib yam nkaus.
• Ob qho xwm txheej yuav tshwm sim tib yam yog tias lub nkoj thaiv yog tib yam.
• Cov tshuaj uas ua rau cov ntshav tsis tuaj yeem tiv thaiv cov hlab ntsha. Cov tshuaj uas tso tseg cov ntshav tsis txhob txhaws cov hlab ntsha. Ua tib zoo tuav cov pob txha tawg kom tsis txhob muaj roj embolism.
