Qhov Tseem Ceeb Qhov txawv - Aneurysm vs Ntshav Clot
Ib qho chaw nyob ruaj khov ntawm cov hlab ntsha lossis phab ntsa ntawm lub plawv hu ua aneurysm. Cov ntshav txhaws yog ib qho meshwork ntawm fibrin fibers khiav hauv txhua qhov kev qhia thiab nkag mus rau cov qe ntshav, platelets thiab plasma. Yog li ntawd, nws tuaj yeem nkag siab meej tias qhov sib txawv tseem ceeb ntawm cov ntshav txhaws thiab aneurysm nyob hauv lawv qhov chaw; aneurysm tsim nyob rau hauv cov hlab ntsha los yog nyob rau hauv lub plawv phab ntsa whereas ib tug ntshav txhaws nyob rau hauv cov ntshav.
Aneurysm yog dab tsi?
Aneurysm yog ib qho chaw nyob ruaj khov ntawm cov hlab ntsha lossis phab ntsa ntawm lub plawv. Aneurysms tuaj yeem muab faib ua peb txoj kev sib txawv raws li peb yam sib txawv.
Tswj hom ntawm Aneurysm
1. Aneurysm Raws li Qhov Xwm ntawm Lub Nkoj Phab Ntsa
True Aneurysm
Yog phab ntsa tsis zoo, nws hu ua aneurysm tseeb. e.g. - Atherosclerotic thiab syphilitic aneuryms
False Aneurysm
Yog tias muaj qhov tsis xws luag hauv phab ntsa, ua rau tsim cov hematoma ntxiv. e.g. - ventricular rupture tom qab myocardial infarction.
2. Aneurysm Raws li Macroscopic Xwm
- Saccular Aneurysm
- Fusiform Aneurysm
- Cylindrical Aneurysm
- Ntxhais kab mob sib kis
3. Raws li qhov chaw ntawm Aneurysm
- Abdominal aortic aneurysm
- Thoracic aortic aneurysm
- Berry aneurysms hauv hlwb
Daim duab 01: Aortic Aneurysm
Pathogenesis ntawm Aneurysm
Vascular phab ntsa yog tsim los ntawm cov ntaub so ntswg sib txuas. Kev tsis zoo ntawm cov ntaub so ntswg tuaj yeem ua rau cov phab ntsa vascular tsis muaj zog. Qhov tsis zoo ntawm qhov tsis zoo ntawm cov ntaub so ntswg vascular yog ib qho tsis xws luag. Kev hloov pauv ntawm qhov zoo sib npaug ntawm qhov degradation thiab rov tsim dua ntawm collagen fibers kuj tuaj yeem ua rau cov hlab ntsha tsis muaj zog thiab qhov no feem ntau tshwm sim los ntawm o. Hauv qee qhov ntawm cov kab mob pathological, cov ntsiab lus ntawm cov khoom tsis-elastic thiab tsis yog-collagenous hauv cov hlab ntsha phab ntsa nce siab. Qhov kev hloov pauv ntawm cov ntaub so ntswg sib txuas no txo qis elasticity thiab ua raws li cov phab ntsa ntawm cov hlab ntsha, thaum kawg ua rau muaj qhov tsis txaus ntseeg. Ob qho laj thawj tseem ceeb ntawm aortic aneurysms yog kub siab thiab atherosclerosis.
Dab tsi yog ntshav txhaws?
Cov ntshav txhaws yog ib qho mesh ua haujlwm ntawm fibrin fibers khiav hauv txhua qhov kev qhia thiab nkag mus rau cov qe ntshav, platelets thiab plasma. Clotting yog ib qho kev ua haujlwm ntawm lub cev uas tau pib los teb rau kev tawg ntawm cov hlab ntsha lossis kev puas tsuaj rau cov ntshav nws tus kheej. Cov stimuli no ua rau cov tshuaj tua kab mob los tsim cov tshuaj hu ua prothrombin activator. Prothrombin activator ces catalyzes hloov ntawm prothrombin rau thrombin. Thaum kawg, thrombin, uas ua raws li ib qho enzyme, catalyzes tsim cov fibrin fibers los ntawm fibrinogen thiab cov fibrin fibers entangle nrog ib leeg, tsim ib tug fibrin mesh uas peb hu ua lub clot.
Daim duab 02: Ntshav Ntshav
Raws li tau hais dhau los, kev ua kom lub cev ntawm cov tshuaj yog xav tau rau kev tsim cov prothrombin activator. Qhov tshwj xeeb ua kom cov tshuaj no tuaj yeem tshwm sim ntawm ob txoj hauv kev loj.
Txoj Kev Ncaj Ncees
Nws yog txoj hauv kev uas tau qhib thaum muaj ntshav raug mob.
Extrinsic Pathway
Txoj kev extrinsic tau qhib thaum cov phab ntsa vascular raug mob lossis cov ntaub so ntswg los ntawm cov ntshav.
Tib neeg lub vascular system siv ntau lub tswv yim txhawm rau tiv thaiv kev tsim cov ntshav txhaws hauv cov hlab ntsha hauv qhov qub.
Endothelial Surface Factors
Qhov smoothness ntawm qhov chaw endothelial pab tiv thaiv kev sib cuag ntawm txoj hauv kev. Muaj lub tsho tiv no ntawm glycocalyx ntawm endothelium uas ua rau cov ntshav txhaws thiab platelets, yog li tiv thaiv kev tsim cov ntshav txhaws. Lub xub ntiag ntawm thrombomodulin, uas yog ib qho tshuaj muaj nyob rau ntawm endothelium pab tiv thaiv cov txheej txheem ntawm cov ntshav txhaws. Thrombomodulin khi nrog thrombin thiab nres kev ua haujlwm ntawm fibrinogen.
- Anti-thrombin kev ua ntawm fibrin thiab antithrombin iii.
- Kev ua ntawm Heparin
- Lysis ntawm cov ntshav txhaws los ntawm plasminogen
Los ntawm cov kev ntsuas no uas peb lub cev muaj, nws pom tseeb tias tib neeg lub cev tsis xav kom muaj cov ntshav txhaws hauv nws nyob rau hauv ib txwm muaj. Tab sis cov ntshav txhaws tuaj yeem tsim nyob rau hauv lub cev khiav tawm tag nrho cov txheej txheem tiv thaiv no.
Cov xwm txheej zoo li kev raug mob, atherosclerosis, thiab kev kis kab mob tuaj yeem ua rau cov kab mob endothelial, yog li ua rau txoj hauv kev ua kom ntshav txhaws.
Txhua yam kab mob uas ua rau cov hlab ntsha nqaim kuj muaj qhov ua rau cov hlab ntsha vim qhov nqaim ntawm cov hlab ntsha qeeb qeeb cov ntshav ntws los ntawm nws thiab yog li ntawd ntau cov procoagulants tau sau nyob rau ntawm qhov chaw, ua kom muaj qhov chaw zoo. rau kev tsim cov ntshav txhaws.
Dab tsi zoo sib xws ntawm Aneurysm thiab ntshav txhaws?
Qhov zoo sib xws ntawm aneurysm thiab ntshav txhaws yog tias ob qho tib si tshwm sim hauv cov hlab ntshav

| Yuav siv sijhawm ntev rau qhov mob aneurysm tsim nyob rau hauv lub nkoj phab ntsa. | Kev tsim cov ntshav txhaws yuav siv sijhawm luv dua. |
Summary – Aneurysm vs Blood Clot
Cov kab mob sib tham ntawm no yog ob hom kab mob uas tau pom hauv kev kho mob. Qhov sib txawv tseem ceeb ntawm cov ntshav txhaws thiab aneurysm yog lawv qhov chaw; aneurysm yog tsim nyob rau hauv lub hlab ntsha los yog nyob rau hauv lub phab ntsa ntawm lub plawv thaum ib tug ntshav txhaws yog Ameslikas tsim nyob rau hauv cov ntshav. Cov ntsiab lus zoo xws li lub sijhawm ntawm cov tsos mob tuaj yeem pab tau rau kev kuaj mob tab sis nws nyuaj rau kev kuaj mob kom paub tseeb yam tsis tau tshawb xyuas ntxiv.
