Thrombosis tsuas yog lub cev lub cev cov ntshav txhaws mechanism.Yog tsis muaj thrombus, feem ntau cov neeg yuav tuag los ntawm "cov ntshav ntau dhau".
Peb txhua tus tau raug mob thiab los ntshav, xws li kev txiav me me ntawm lub cev, uas yuav los ntshav sai sai.Tab sis tib neeg lub cev yuav tiv thaiv nws tus kheej.Txhawm rau tiv thaiv los ntshav kom txog thaum tuag, cov ntshav yuav maj mam coagulate ntawm qhov chaw los ntshav, uas yog, cov ntshav yuav tsim ib qho thrombus hauv cov hlab ntsha puas.Ua li no, tsis txhob los ntshav.
Thaum cov ntshav tso tseg, peb lub cev yuav maj mam yaj cov thrombus, tso cai rau cov ntshav rov qab.
Lub tshuab uas tsim cov thrombus hu ua coagulation system;Lub tshuab uas tshem tawm cov thrombus yog hu ua fibrinolytic system.Thaum cov hlab ntsha puas lawm hauv tib neeg lub cev, lub coagulation system yog qhib tam sim ntawd kom tsis txhob los ntshav ntxiv;Thaum ib tug thrombus tshwm sim, lub fibrinolytic system uas tshem tawm cov thrombus yuav qhib kom yaj cov ntshav txhaws.
Ob lub tshuab ua kom muaj zog sib npaug, kom ntseeg tau tias cov ntshav tsis coagulates lossis los ntshav ntau dhau.
Txawm li cas los xij, ntau yam kab mob yuav ua rau kev ua haujlwm tsis zoo ntawm lub coagulation system, nrog rau kev puas tsuaj rau cov hlab ntsha intima, thiab cov ntshav stasis yuav ua rau cov kab mob fibrinolytic lig dhau los yog tsis txaus kom yaj cov thrombus.
Piv txwv li, nyob rau hauv mob myocardial infarction, muaj thrombosis nyob rau hauv lub plawv cov hlab ntsha.Cov kab mob ntawm cov hlab ntsha tsis zoo, muaj ntau yam kev puas tsuaj intima, thiab muaj stenosis, ua ke nrog stagnation ntawm cov ntshav khiav, tsis muaj txoj hauv kev kom yaj cov thrombus, thiab cov thrombus tsuas yog loj dua.
Piv txwv li, nyob rau hauv cov neeg uas pw nyob rau hauv ib tug ntev lub sij hawm, lub zos cov ntshav ntws nyob rau hauv ob txhais ceg yog qeeb, intima ntawm cov hlab ntsha puas, thiab ib tug thrombus tsim.Lub thrombus yuav yaj mus ntxiv, tab sis lub dissolving ceev tsis txaus, nws yuav poob tawm, ntws rov qab mus rau hauv cov hlab ntsha pulmonary raws li cov ntshav system, tau daig nyob rau hauv cov hlab ntsha pulmonary, thiab ua rau pulmonary embolism, uas yog tseem tuag taus.
Nyob rau lub sijhawm no, txhawm rau ua kom muaj kev nyab xeeb ntawm cov neeg mob, nws yog ib qho tsim nyog yuav tsum tau ua cov tshuaj thrombolysis thiab txhaj tshuaj siv los txhawb thrombolysis, xws li "urokinase".Txawm li cas los xij, thrombolysis feem ntau yuav tsum tau ua hauv lub sijhawm luv luv ntawm thrombosis, xws li hauv 6 teev.Yog nws siv sij hawm ntev, nws yuav tsis yaj.Yog tias koj nce kev siv cov tshuaj thrombolytic rau lub sijhawm no, nws yuav ua rau los ntshav hauv lwm qhov ntawm lub cev.
Lub thrombus tsis tuaj yeem yaj.Yog tias nws tsis tau thaiv tag nrho, "stent" tuaj yeem siv los "rub" cov hlab ntsha uas thaiv tau kom cov ntshav ntws zoo.
Txawm li cas los xij, yog tias cov hlab ntsha raug thaiv ntev, nws yuav ua rau ischemic necrosis ntawm cov ntaub so ntswg tseem ceeb.Lub sijhawm no, tsuas yog los ntawm "kev hla" lwm cov hlab ntsha tuaj yeem nkag mus rau "kua dej" cov ntaub so ntswg uas tau poob nws cov ntshav.
Los ntshav thiab coagulation, thrombosis thiab thrombolysis, nws yog qhov sib npaug zoo uas tswj lub cev cov dej num metabolic.Tsis tas li ntawd xwb, muaj ntau qhov sib npaug ntawm tib neeg lub cev, xws li cov paj hlwb thiab cov paj hlwb vagus, uas tswj cov tib neeg lub siab tsis zoo siab heev;insulin thiab glucagon tswj tib neeg cov ntshav qab zib sib npaug;calcitonin thiab parathyroid hormone tswj tib neeg cov ntshav qab zib.
