Nyob rau hauv ib txwm muaj mob, cov ntshav circulates nyob rau hauv ib qho kev txiav txim nyob rau hauv cov hlab ntsha thiab tswj qhov sib npaug ntawm cov yam uas nyiam thiab cov uas tiv thaiv coagulation. Txawm li cas los xij, thaum muaj kev hloov pauv hauv cov ntshav, hauv phab ntsa ntawm cov hlab ntsha lossis hauv cov ntshav coagulation, thrombi tuaj yeem tsim tawm hauv cov hlab ntsha, uas yuav ua rau tsis muaj dej hauv cov kabmob lossis cov cheeb tsam hauv lub cev uas ib txwm muab los ntawm cov hlab ntsha.
Yog koj xav paub ntxiv txog dab tsi yog thrombosis hauv dev, nws kho thiab cov tsos mob , koom nrog peb hauv tsab xov xwm tom ntej ntawm peb qhov chaw uas peb yuav piav qhia qhov tseem ceeb tshaj plaws ntawm cov kab mob no, nws ua rau thiab kuaj mob.
Dab tsi yog thrombosis hauv dev?
Thrombosis yog cov txheej txheem pathological uas tshwm sim los ntawm coagulation ntawm cov ntshav hauv cov hlab ntsha lossis hauv plawvntawm cov tsiaj muaj sia. Cov ntshav dhau los ntawm lub xeev ua kua los ua ib qho khoom loj, hu ua thrombus, uas tag nrho los yog ib nrab occludes lub nkoj uas nws nyob. Qhov no ua rau muaj kev cuam tshuam cov hlab ntsha hauv lub nkoj thiab cuam tshuam cov ntshav mus rau lub cev lossis lub cev thaj chaw uas tau muab los ntawm cov hlab ntsha cuam tshuam.
thrombosis and embolism yog cov ntsiab lus uas feem ntau tsis meej pem, txawm li cas los xij, tsis txhob txhais raws nraim tib yam. Thrombi ib txwm nyob twj ywm rau ntawm phab ntsa ntawm cov hlab ntsha, txawm li cas los xij, emboli yog ib feem ntawm lub thrombus uas tawg thiab taug kev los ntawm cov hlab ntsha mus txog rau thaum lawv ncav cuag ib lub nkoj me me kom occlude nws.
Txawm hais tias thrombi hauv dev tuaj yeem nyob hauv txhua txoj hlab ntsha, nws pom ntau dua hauv:
- Pulmonary ncig.
- Lub raum ncig.
- Nyob thoob plaws hauv lub circulatory system (multiorgan kev koom tes).
Peb lub tswv yim uas tuaj yeem ua rau cov txheej txheem pathological no hu ua "Virchow's triad", uas suav nrog:
- Kev hloov pauv hauv cov ntshav: turbulence, eddies lossis slowing phenomena (ntshav stasis) disorganize cov ntws ntws hauv cov hlab ntsha, uas nyiam cov tsim ntawm thrombi.
- platelets tsis zoo circulate nyob ib ncig ntawm lub periphery, thiab cov hlab ntsha endothelial hlwb kuj muaj ib tug tsis zoo nqi, ua rau lawv ib leeg. Txawm li cas los xij, thaum lub nkoj endothelium raug mob, qhov zoo tshaj plaws subendothelium raug nthuav tawm, txhawb cov platelets kom sib sau thiab khi rau ntawm phab ntsa hlab ntsha.
- Hypercoagulability states: muaj qee yam pathologies uas ua rau muaj qhov tsis txaus ntseeg ntawm cov tshuaj tiv thaiv coagulant thiab cov tshuaj tiv thaiv coagulant, uas txhawb kev tsim cov thrombi.
Ib yam ntawm cov laj thawj no, ib leeg lossis ua ke, tuaj yeem ua rau thrombus tsim ncaj qha.
Ua rau thrombosis hauv dev
Dab tsi tuaj yeem ua rau thrombosis hauv dev? Raws li peb tau piav qhia, thrombosis tshwm sim los ntawm qee qhov kev hloov pauv uas ua rau Virchow's triad. Tshwj xeeb, cov laj thawj uas tuaj yeem ua rau txhua qhov kev hloov pauv no yog:
- : Kab mob plawv (feem ntau yog endocarditis thiab endocardiosis), anatomical malformations, nce ntshav viscosity thiab ntev decubitus.
- Blood vessel wall raug mob: Systemic Inflammatory Response Syndrome (SIRS), sepsis, heartworms, neoplasms, raug mob hnyav, raug mob los ntawm kev txhaj tshuaj lossis Cov kab mob hauv cov hlab ntsha, vasculitis, poob siab, atherosclerosis
- Hypercoagulable states: Cushing's syndrome, mob raum, kab mob plab, pancreatitis, disseminated vascular coagulation (DIC), neoplasms thiab kab mob plawv.
Tshwj xeeb, thrombi hauv dev yog tshwj xeeb tshaj yog nyob rau hauv cov mob sepsis, kab mob raum, thiab kab mob plawv.
Symptoms of thrombosis in dogs
Cov tsos mob ntawm thrombosis tshwm sim los ntawm qhov tsis muaj ntshav txaus (ischemia) ntawm cov kab mob hauv nruab nrog cev lossis cheeb tsam hauv lub cev uas ib txwm muab. los ntawm lub nkoj cuam tshuam. Qee cov tsos mob feem ntau pom nyob rau hauv cov mob thrombosis hauv dev yog:
- qaug zog lossis tuag tes tuag taw tom qab (xws li mob aortic thrombosis).
- No pulse.
- Pab mob hauv cheeb tsam lub cev.
- Hypothermia ntawm thaj tsam cuam tshuam lub cev.
- Cov tsos mob tsis ua hauj lwm: Nyob ntawm cov kab mob cuam tshuam, cov cim qhia ntawm lub raum, daim siab, ua pa tsis ua haujlwm, thiab lwm yam tuaj yeem tshwm sim.
Diagnosis of thrombosis in dogs
Tus neeg mob cov tsos mob tuaj yeem ua rau muaj qhov tsis txaus ntseeg ntawm thrombosis, txawm li cas los xij, kom mus txog qhov kev kuaj mob ntawm tus kab mob thrombotic nws yog ib qho tsim nyog yuav tsum tau ua ntau yam kev ntsuam xyuas ntxiv:
- Bloodwork: Cov ntshav yuav tsum tau muab coj los ntawm tus neeg mob los ntsuas lub sij hawm txhaws, platelet suav, txiav txim siab ntawm fibrinogen, antithrombin thiab fibrin degradation. cov khoom (PDFs thiab D-dimers). Txawm li cas los xij, nws yuav tsum tau coj mus rau hauv tus account tias cov kev kuaj sim no tsis yog tshwj xeeb rau kev kuaj mob thrombosis, yog li cov txiaj ntsig ib txwm yuav tsum tsis txhob txiav txim siab tus kab mob.
- Colour Doppler Ultrasound: Qhov no yog hom ultrasound uas ntsuas cov ntshav ntws hauv cov hlab ntsha los ntawm kev tso saib qhov ceev thiab kev taw qhia ntawm cov ntshav tiag tiag. lub sij hawm.
- Angiography: Qhov no yog ib hom kev sib txawv x-ray uas cov khoom sib txawv tau nkag mus rau hauv cov hlab ntsha.
Txawm hais tias kev ntsuam xyuas cov duab tso cai rau kev kuaj mob thrombotic, nws yog ib qho tsim nyog yuav tsum tau ua lub roj teeb ntawm kev kuaj mob ntxiv rau kev paub txog qhov ua tau ntawm thrombosis. Vim li no, nyob rau hauv cov tsiaj no nws yog advisable mus nqa tawm:
- Urinalysis: with protein/creatinine ratio.
- Echocardiography.
- x-ray.
Tsuas yog txoj hauv kev no peb thiaj tuaj yeem txiav txim siab qhov tseem ceeb ntawm cov kab mob thrombosis thiab tsim kom muaj kev kho mob uas tiv thaiv kev tsim cov thrombi tshiab.
Tshuaj mob thrombosis hauv dev
Thaum thrombi tsis ntev los no thiab me me, lub cev muaj peev xwm ua kom puas tsuaj ua tsaug rau qhov kev ua ntawm thrombolysin. Txawm li cas los xij, nyob rau hauv cov mob ntev lossis loj thrombi, nws yog ib qho tseem ceeb los tsim kev kho mob raws li cov ntsiab lus hauv qab no:
- Induce a state of hypocoagulability: kom txo tau cov thrombus tsim. Qhov no ua tiav los ntawm kev siv cov tshuaj fibrinolytic los yog tshuaj antithrombotic (xws li heparin thiab clopidogrel).
- Surgery: Thaum tus neeg mob cov xwm txheej tso cai, nws yuav tsum tshem tawm cov thrombus siv cov txheej txheem thrombectomy (kev phais lossis percutaneous catheterization.)), uas kho cov ntshav ntws hauv cov hlab ntsha cuam tshuam.
Ntxiv mus, thaum twg los tau, yuav tsum tsim kom muaj ib tug phenomenon, tiv thaiv kev tsim ntawm thrombi tshiab.
