Thrombosis - cov kab mob uas zais hauv cov hlab ntsha
Thaum cov av ntau ntau tso rau hauv tus dej, cov dej ntws yuav qeeb, thiab cov ntshav yuav ntws mus rau hauv cov hlab ntsha, ib yam li cov dej hauv dej.Thrombosis yog "silt" nyob rau hauv cov hlab ntsha, uas tsis tsuas yog cuam tshuam cov ntshav khiav, tab sis kuj cuam tshuam rau lub neej nyob rau hauv mob hnyav.
Ib qho thrombus tsuas yog "cov ntshav txhaws" uas ua zoo li lub ntsaws los thaiv cov hlab ntsha hauv ntau qhov chaw ntawm lub cev.Feem ntau cov thromboses yog asymptomatic tom qab thiab ua ntej pib, tab sis tam sim ntawd tuag yuav tshwm sim.
Vim li cas tib neeg muaj ntshav txhaws hauv lub cev
Muaj coagulation system thiab anticoagulation system nyob rau hauv tib neeg cov ntshav, thiab ob tug tswj ib tug dynamic tshuav nyiaj li cas los xyuas kom meej qhov zoo ntawm cov ntshav nyob rau hauv cov hlab ntsha.Cov txheej txheem coagulation thiab lwm yam tsim nyob rau hauv cov ntshav ntawm qee cov pab pawg muaj kev pheej hmoo siab tau yooj yim tso rau hauv cov hlab ntsha, sib sau ua ke los ua cov thrombus, thiab thaiv cov hlab ntsha, ib yam li cov sediment ntau tso rau hauv qhov chaw uas cov dej ntws. slows cia nyob rau hauv tus dej, uas tso cov neeg nyob rau hauv ib tug "nrhiav qhov chaw".
Thrombosis tuaj yeem tshwm sim hauv cov hlab ntsha nyob qhov twg hauv lub cev, thiab nws tau muab zais heev kom txog thaum nws tshwm sim.Thaum cov ntshav txhaws tshwm sim hauv cov hlab ntsha ntawm lub hlwb, nws tuaj yeem ua rau cerebral infarction, thaum nws tshwm sim hauv cov hlab ntsha, nws yog myocardial infarction.
Feem ntau, peb faib cov kab mob thrombotic rau ob hom: arterial thromboembolism thiab venous thromboembolism.
Arterial thromboembolism: Ib qho thrombus yog cov ntshav txhaws uas nkag mus rau hauv cov hlab ntsha.
Cerebrovascular thrombosis: Cerebrovascular thrombosis tej zaum yuav tshwm sim nyob rau hauv ib qho kev ua tsis taus pa, xws li hemiplegia, aphasia, qhov muag tsis pom kev thiab tsis hnov tsw, coma, thiab qhov mob hnyav tshaj plaws, nws tuaj yeem ua rau muaj kev tsis taus thiab tuag taus.
Cardiovascular Embolism: Cov hlab plawv embolization, qhov twg cov ntshav txhaws nkag mus rau hauv cov hlab ntsha, tuaj yeem ua rau mob hnyav angina pectoris lossis txawm tias myocardial infarction.Thrombosis nyob rau hauv cov hlab ntsha peripheral tuaj yeem ua rau muaj kev cuam tshuam ntawm claudication, mob, thiab txawm tias kev txiav ntawm ob txhais ceg vim gangrene.
Venous thromboembolism: Hom thrombus no yog cov ntshav txhaws nyob rau hauv cov hlab ntsha, thiab qhov tshwm sim ntawm venous thrombosis yog ntau dua li ntawm arterial thrombosis;
Venous thrombosis feem ntau cuam tshuam nrog cov leeg ntawm cov leeg qis, ntawm cov leeg sib sib zog nqus thrombosis ntawm qis extremities yog feem ntau.Dab tsi txaus ntshai yog tias qhov sib sib zog nqus hlab ntsha ntawm cov leeg qis tuaj yeem ua rau pulmonary embolism.Ntau tshaj 60% ntawm pulmonary emboli nyob rau hauv kev kho mob xyaum los ntawm cov hlab ntsha sib sib zog nqus thrombosis ntawm qis extremities.
Venous thrombosis kuj tseem tuaj yeem ua rau mob plawv tsis ua haujlwm, ua tsis taus pa, mob hauv siab, hemoptysis, syncope, thiab txawm tias tam sim no tuag.Piv txwv li, ua si hauv computer ntev heev, lub hauv siab ceev ceev thiab kev tuag tam sim ntawd, feem ntau yog pulmonary embolism;cov tsheb ciav hlau mus sij hawm ntev thiab dav hlau, cov ntshav venous ntawm cov leeg qis yuav qeeb, thiab cov hlab ntsha hauv cov ntshav yuav ntau dua los dai rau ntawm phab ntsa, tso nyiaj, thiab tsim cov ntshav txhaws.
