Thrombosis inzira iyo ropa rinoyerera rinoputika uye rinoshanduka kuva jira reropa, senge cerebral artery thrombosis (inokonzera cerebral infarction), yakadzika mutsinga thrombosis yemucheto wezasi, nezvimwewo. Iyo yakaumbwa ropa clot is thrombus;ropa rakagwamba rinoumbwa mune imwe tsinga yeropa rinofamba richitevedza tsinga yeropa uye rinovharirwa kune imwe tsinga yeropa.Nzira yekusimbisa inonzi embolism.Iyo yakadzika vein thrombosis yemakumbo ezasi inodonha, inotama, uye inovharirwa kune pulmonary artery uye inokonzera pulmonary embolism.;Ropa rinoputika rinokonzera embolism rinonzi embolus panguva ino.
Muhupenyu hwezuva nezuva, kuvhara kweropa kunoputika mushure mokunge ropa remhino ramiswa;apo ronda rinokuvadzwa, bundu rinogona kunzwika dzimwe nguva, iro ririwo thrombus;uye myocardial infarction inokonzerwa nekukanganiswa kwekuyerera kweropa apo tsinga yekorona iyo inogara mukati memwoyo yakavharwa neropa rekuvhara Ischemic necrosis yemyocardium.
Pasi pemamiriro ehupenyu, basa re thrombosis kumisa kubuda ropa.Kugadziriswa kwechero nyama uye nhengo kunofanira kutanga kumisa kubuda ropa.Hemophilia icoagulopathy inokonzerwa nekushaikwa kwezvinhu zvinosangana.Zvakaoma kuumba thrombus muchikamu chakakuvara uye haigoni kunyatsomisa kubuda ropa uye kukonzera kubuda ropa.Yakawanda hemostatic thrombosis inoita uye inowanikwa kunze kwetsinga yeropa kana pakatyoka tsinga yeropa.
Kana ropa rakagwamba mutsinga yeropa, kuyerera kweropa mutsinga yeropa kunovharika, kuyerera kweropa kunoderera, kana kuti kunyange kuyerera kweropa kunovhiringidzwa.Kana thrombosis ikaitika mutsinga, inokonzera nhengo / tishu ischemia uye kunyange necrosis, yakadai semyocardial infarction, cerebral infarction, uye kumucheto kwepasi necrosis / amputation.Iyo thrombus inoumbwa mutsinga dzakadzika dzezasi dzepasi haingokanganise chete kuyerera kweropa remukati mukati memoyo uye rinokonzeresa kuzvimba kwezasi, asi zvakare inodonha kuburikidza neiyo inferior vena cava, right atrium uye right ventricle kupinda nekuvharira mukati. iyo pulmonary artery, zvichikonzera pulmonary embolism.Zvirwere zvine mwero wepamusoro wekufa.
Thrombosis kutanga
Muzviitiko zvakawanda, iyo yekutanga link ye thrombosis inokuvadza, iyo inogona kuva kushungurudzika, kuvhiyiwa, kuputika kweplaque mutsinga, kana kunyange kuparara kwekupedzisira kunokonzerwa nehutachiona, hutachiona uye zvimwe zvinhu.Iyi nzira yekuumbwa kwethrombus yakatangwa nekukuvara inonzi exogenous coagulation system.Muzviitiko zvishomanana, kuderera kweropa kana kuderera kwekuyerera kweropa kunogonawo kutanga nzira ye thrombosis, iyo inzira yekubatana nayo, inonzi endogenous coagulation system.
Primary hemostasis
Kamwe kukuvara kwakanganisa tsinga dzeropa, maplatelet anotanga kunamatira kuumba danda rimwe chete kuvhara ronda, uye zvino rinoitwa kuti riunganidze kuita masumbu, ayo ari platelet thrombi.Zvose izvi zvinonzi primary hemostasis.
Secondary hemostasis
Kukuvara kunoburitsa coagulation chinhu chinonzi tissue factor, chinotanga endogenous coagulation system kuburitsa thrombin mushure mekupinda muropa.Thrombin ichokwadi inokonzeresa inoshandura coagulation protein iri muropa, kureva, fibrinogen kuita fibrin., Iyo yose nzira inonzi yechipiri hemostasis.
"Perfect Interaction"Thrombosis
Mukuita kwethrombosis, danho rekutanga rehemostasis (platelet adhesion, activation uye aggregation) uye chikamu chechipiri chehemostasis (thrombin production uye fibrin formation) inoshanda pamwe chete.Chechipiri-nhanho hemostasis inogona kungoitwa kazhinji muhupo hwemaplatelet, uye iyo yakaumbwa thrombin inowedzera kuita maplatelet.Vaviri vanoshanda pamwe chete uye vanoshanda pamwechete kuti vapedze chirongwa che thrombosis.
