Pulmonary hypertension yog ib qho kev tshawb nrhiav pathological feem ntau pom nyob rau hauv cov chaw kho tsiaj me, uas muaj cov ntshav siab systolic lossis diastolic hauv cov hlab ntsws. Nws cov tsos mob tuaj yeem yog vim muaj ntau yam ua rau, feem ntau ntawm lawv muaj feem cuam tshuam nrog kev hloov pauv hauv plawv lossis pulmonary, uas txiav txim siab tsis yog kev kuaj mob nkaus xwb, tab sis kuj yog kev kho mob ntawm qhov kev hloov pauv no.
Yog koj xav paub ntau ntxiv txog pulmonary hypertension in dogs, peb xav kom koj sab laj cov lus hauv qab no ntawm peb qhov chaw, hauv qhov uas peb piav qhia txog qhov tseem ceeb tshaj plaws ntawm qhov kev tshawb pom pathological no, suav nrog nws qhov ua rau, cov tsos mob, kev kuaj mob thiab kev kho mob.
Pulmonary Hypertension hauv dev yog dab tsi?
Ua ntej txhais tias pulmonary hypertension yog dab tsi, nws yuav tsum tau piav qhia dav dav cov hlab ntsha, hlab ntsha thiab capillaries) thiab lub plawv. Cov kab mob plawv muab faib ua ob lub voj voog: cov kab mob dav dav lossis cov kab mob hauv lub ntsws thiab cov hlab ntsws. Lub hom phiaj ntawm txoj kev dav dav yog thauj cov ntshav oxygenated mus rau cov ntaub so ntswg, thaum lub hom phiaj ntawm lub ntsws txoj hlab ntsws yog thauj cov ntshav deoxygenated mus rau lub ntsws kom nws tuaj yeem rov ua dua tshiab. Ob lub voj voog sib txuas thiab hla ntawm theem ntawm lub plawv, ua los ntawm ob chav sab laug (sab laug atrium thiab sab laug ventricle, uas sib txuas lus nrog ib leeg) thiab ob chav sab xis (txoj cai atrium thiab txoj cai ventricle, uas kuj sib txuas lus nrog ib leeg). Sab laug atrium tau txais cov ntshav oxygenated los ntawm cov hlab ntsws, uas nkag mus rau sab laug ventricle, los ntawm qhov chaw uas nws muab faib rau tag nrho cov ntaub so ntswg los ntawm kev ncig. Txoj cai atrium tau txais cov ntshav deoxygenated los ntawm cov kev khiav dav dav, uas dhau mus rau sab xis ventricle los ntawm qhov chaw uas nws tau muab faib rau lub ntsws, los ntawm cov hlab ntsws, kom tau oxygenated dua.
Thaum peb paub ob hom kev ncig uas muaj nyob, peb tuaj yeem mus txhais tau pulmonary hypertension, uas muaj pab ntshav siab ntau ntxiv
Types pulmonary hypertension in dogs
Pulmonary hypertension tuaj yeem yog ob hom:
- Primary or idiopathic pulmonary hypertension: thaum lub hauv paus tsis paub
- : thaum nws tshwm sim los ntawm lwm yam kab mob. Nws yog qhov nquag.
Thiab, theem nrab pulmonary ntshav siab tuaj yeem muab faib ua peb pawg nyob ntawm nws cov etiology:
- Hyperkinetic pulmonary hypertension: yog tshwm sim los ntawm cov ntshav ntws mus rau lub ntsws, feem ntau yog vim muaj vascular malformations uas tso cai rau cov ntshav mus rau hauv lub ntsws. sab laug mus rau sab xis ntawm lub siab.
- Passive pulmonary hypertension: tshwm sim vim nyuaj rau pulmonary venous kua, feem ntau yog tshwm sim los ntawm sab laug plawv tsis ua hauj lwm.
- Angio-occlusive pulmonary hypertension: tshwm sim vim muaj vascular tsis kam nyob rau hauv lub ntsws. Nws yog hom mob pulmonary ntshav siab tshaj plaws.
Symptoms of pulmonary hypertension in dogs
Daim duab kho mob cuam tshuam nrog pulmonary hypertension tuaj yeem hloov pauv. Hauv cov dev uas muaj mob pulmonary hypertension, feem ntau tsuas pom cov tsos mob tshwm sim yog cov cuam tshuam nrog thawj pathology ua rau mob ntshav siab.
Nyob rau hauv cov neeg mob
- tus yam ntxwv ntawm thawj kab mobuas ua rau mob siab.
- Dyspnea (ua pa nyuaj siab): Thaum pib tsuas yog ua tsis taus pa ntawm kev tawm dag zog tuaj yeem tshwm sim, tab sis nyob rau hauv qhov hnyav dyspnea thaum so tuaj yeem pom.
- Cyanosis: bluish discoloration ntawm mucous daim nyias nyias.
- Syncope: cov no yog ntu uas tshwm sim nrog kev tsis nco qab tam sim ntawd, ua raws li kev ua tiav thiab feem ntau rov qab los sai sai. Lawv feem ntau tshwm sim los ntawm cov xwm txheej ntawm kev zoo siab lossis kev tawm dag zog lub cev, txawm hais tias muaj mob hnyav, kev taug kev yooj yim lossis nce toj qee qhov tuaj yeem ua rau lawv.
- Thaum koom nrog kev muaj txoj cai congestive lub plawv tsis ua haujlwm, nws tuaj yeem pom plab plab vim ascites, jugular distension, jugular pulse thiab pleural effusion.
Ua rau pulmonary hypertension hauv dev
Cov laj thawj tshwj xeeb uas tuaj yeem ua rau mob ntshav siab hauv dev tau muab faib ua cov kab mob hauv qab no:
- Cov kab mob uas ua rau muaj kev ntxhov siab nyob rau sab laug atrium: nyob rau hauv cov mob sab laug tsis ua hauj lwm vim degenerative mitral valve kab mob los yog cardiomyopathy. Lawv ua rau cov ntshav siab ntshav siab.
- Cov kab mob uas tsim cov ntim ntau dhau ntawm pulmonary circulation theem: vim vascular malformations xws li atrial septal defect (persistent Botal foramen), ventricular septal defect, thiab patent ductus arteriosus (PDA). Lawv ua rau hyperkinetic pulmonary hypertension.
- kab mob pulmonary ncig: xws li dirofilariosis, angiostrogillosis, neoplasia, septicemia, autoimmune hemolytic anemia, hyperadrenocorticism, nephrotic syndrome thiab coagulation. Disseminated intravascular disease (DIC). Lawv ua rau angio-occlusive pulmonary hypertension.
- : xws li kab mob ntsws interstitial, mob obstructive kab mob los yog nyob ntev ntawm qhov siab. Cov xwm txheej no ua rau txo qis hauv cov hlab ntsha oxygen siab, uas ua rau vasoconstriction ntawm pulmonary arterioles thiab ua rau angio-occlusive hypertension.
Diagnosis of Pulmonary Hypertension in Dogs
- Medical history and anamnesis: Cov neeg zov me nyuam feem ntau piav qhia txog daim duab kho mob uas ua rau muaj kev tawm dag zog tsis haum, ua tsis taus pa, hnoos, syncope, thiab lwm yam.
- Kev Tshuaj Xyuas Lub Cev-Kev ntsuam xyuas dav dav yuav pom muaj cov tsos mob xws li mob plab vim ascites lossis dyspnea thaum so. Cov lus yws tuaj yeem raug kuaj pom ntawm cardiopulmonary auscultation.
- Chest x-ray: dilation of the right chambers of the heart, the pulmonary trunk and the pulmonary arteries, as well as infiltrates. yuav kuaj pulmonary. Tsis tas li ntawd, kev tshwm sim ntawm thawj kab mob uas ua rau mob ntshav siab tuaj yeem pom.
- Electrocardiogram: nyob rau hauv feem ntau cov neeg mob pulmonary hypertension lub electrocardiogram yog ib txwm, txawm hais tias nyob rau hauv mob hnyav siab P nthwv dej thiab peaky, sib sib zog nqus S nthwv dej thiab txoj cai axis sib txawv.
- Ob-dimensional echocardiography thiab M hom: nyob rau hauv cov neeg mob uas muaj mob ntshav siab mus rau hnyav, hypertrophy thiab dilatation ntawm txoj cai ventricle yuav raug soj ntsuam., thiab dilation ntawm pulmonary hlab ntsha. Txawm li cas los xij, muaj cov neeg mob pulmonary hypertension uas tsis pom qhov txawv txav ntawm echocardiographic, yog li qhov txiaj ntsig tsis zoo hauv qhov kev sim no yuav tsum tsis txhob txiav txim siab pulmonary hypertension.
Tag nrho cov kauj ruam no pab qhia kev kuaj mob. Txawm li cas los xij, mus cuag cov kev kuaj mob ntawm cov dev, nws yog qhov tsim nyog rau NOJ NOJ DEJ. Systemic pressure, uas yog, lub siab uas muaj nyob rau ntawm theem ntawm cov kev ncig, tuaj yeem txiav txim tau yooj yim siv ob qho tib si invasive thiab non-invasive cov tswv yim. Txawm li cas los xij, kev txiav txim siab pulmonary siab yog qhov nyuaj dua. Cov txheej txheem invasive tsis muaj txiaj ntsig vim tias cov kab mob pulmonary arterial tsis tuaj yeem siv ncaj qha, tshwj tsis yog los ntawm kev mob plawv catheterization. Vim li no, yuav tsum tau siv cov txuj ci uas tsis yog-invasive, xws li Doppler echocardiographic study, uas tso cai rau kwv yees ntawm pulmonary artery pressures.
Tshwj xeeb, Doppler echocardiography tso cai rau kev kuaj mob pulmonary hypertension los ntawm kev kuaj pom ib tus ntshav siab tshaj tawm tus nqi hauv tricuspid lossis pulmonary regurgitationPulmonary hypertension values . yuav raug suav hais tias yog cov uas lub tricuspid regurgitation tshaj tawm yog ntau tshaj 2.4 m / s thiab cov nyob rau hauv lub pulmonary regurgitation tshaj tawm yog ntau tshaj 2 m / s.
Khob pulmonary hypertension hauv dev
Yuav kom kho cov kab mob pulmonary hypertension hauv dev, cov ntsiab lus hauv qab no yuav tsum tau coj mus rau hauv tus account:
- Pab txhawb kev kho mob: nws lub hom phiaj yog los tswj cov thawj kab mob thiab nws cov teeb meem.
- Kho nrog pulmonary arterial vasodilators: thaum kev kho mob txhawb nqa tswj cov thawj pathology tab sis pulmonary hypertension tseem muaj thiab cov tsos mob cuam tshuam nrog nws, pulmonary arterial vasodilators, xws li sildenafil, yuav tsum tau noj.
- Kho mob sab xis-sab congestive heart failure (thaum muaj).
Tiv thaiv pulmonary hypertension hauv dev
Raws li peb tau piav qhia hauv kab lus no, pulmonary hypertension tuaj yeem tshwm sim los ntawm ntau yam ua rau. Kev tiv thaiv nws cov tsos yog ib qho teeb meem nyuaj los yog tsis yooj yim sua nyob rau hauv qee kis, vim muaj tsiaj muaj zog predisposition vim yug los yog hnub nyoog los tsim cov kab mob uas tshwm sim thib ob pulmonary kub siab.
Qhov tseeb tias kev tiv thaiv qhov pib ntawm pulmonary hypertension yog qhov nyuaj ua rau nws tseem ceeb heev kuaj mob ntxov ntawm pathologies uas tuaj yeem ua rau kub siab, thiaj li. tsim kom muaj kev kho mob kom txaus sai li sai tau thiab tsis txhob muaj teeb meem. Hauv qhov kev nkag siab no:
- Nyob hauv dev ntawm me me thiab cov laus, uas muaj ib tug tshwj xeeb predisposition rau kev txom nyem los ntawm degenerative kab mob ntawm lub mitral valve, lawv yuav tsum tau. yuav tsum tau mus kuaj xyuas tus kab mob kom sai li sai tau thiab tiv thaiv cov tsos mob ntawm pulmonary hypertension.
- Nyob hauv puppies nws yog ib qho tseem ceeb uas yuav tsum tau ua kom zoo cardiopulmonary auscultation thaum muaj hnub nyoog ntxov, txhawm rau txhawm rau kuaj pom qhov txawv txav hauv lub cev uas tuaj yeem yog ua rau mob ntshav siab pulmonary.
- The dogs that live in high- altitude areas with respect to sea level should be monitored periodically to prevent the effects of low blood pressure ntawm oxygen.
