Hemangiosarcoma yog ib yam ntawm cov nqaij mos neoplasms (mob qog noj ntshav) uas ntshai tshaj plaws los ntawm cov neeg tuav dev. Thiab nws tsis yog qhov xav tsis thoob! Nws yog qhov tsis tshua muaj neeg cuam tshuam thiab metastatic, cuam tshuam rau txhua lub cev vascularized. Nws qhov aggressiveness yog vim kev nthuav tawm sai ntawm cov qog hlwb los ntawm txoj kev hematogenous, nws qhov chaw pib feem ntau yog tus po.
Dab tsi yog hemangiosarcoma hauv dev?
Hemangiosarcoma is a mesenchymal neoplasm uas tshwm sim nyob rau hauv vascular endothelium, thiab suav hais tias yog ib tug malignant, aggressive qog uas yuav cuam tshuam rau ob peb lub cev, tsim. regional los yog nyob deb metastases. Vim nws tus cwj pwm lom neeg, nrog rau qhov siab ntawm hematogenous lossis lymphatic kis, los ntawm cov qog emboli, txog 80% ntawm cov tsiaj, thaum lub sijhawm kuaj mob, twb muaj metastases. Tus aub yog tus tsiaj uas nquag raug mob hauv tsev, tuag los ntawm tus kab mob lossis raug euthanized.
Pib qhov chaw feem ntau yog tus po , tab sis cov kab mob visceral daim ntawv tuaj yeem cuam tshuam rau lwm yam kabmob., xws li tus nplaig, conjunctiva, siab, ntsws, lub mis, pericardium, txoj cai atrium, aorta, ntsws, ob lub raum, cov leeg, pob txha, txoj hnyuv, gallbladder, urinary ib ntsuj av, prostate, qhov chaw mos, thiab peritoneum.. Daim ntawv no ntawm hemangiosarcoma yog feem ntau thiab, txawm hais tias nws cov etiology tsis paub, nws paub tias cuam tshuam los ntawm ntau yam, xws li caj ces, hnub ci hluav taws xob thiab tsis muaj kev tswj hwm ntawm angiogenesis (tsim cov hlab ntsha tshiab)..
Txawm tias tsis tshua muaj tshwm sim, hemangiosarcoma kuj tseem tuaj yeem tshwm sim los ntawm cutaneously, raws li qhov chaw loj lossis metastatic, thiab tuaj yeem cuam tshuam rau dermis thiab subcutaneous. cov ntaub so ntswg, nrog ib tug predilection rau plab, preputial thiab pelvic limb daim tawv nqaij. Cov dev plaub hau luv luv lossis cov xim tsis zoo yog qhov muaj qhov tshwm sim ntau dua thaum raug ultraviolet rays, ua rau muaj qhov sib txawv ntawm tus kab mob. Cutaneous hemangiosarcoma nyob rau hauv dev tsis nruj dua visceral hemangiosarcoma, nrog tsawg metastatic peev xwm.
Causes of hemangiosarcoma in dogs
Lub etiology ntawm hemangiosarcomas tseem tsis tau to taub tag nrho, txawm li cas los xij, ntau qhov laj thawj tau raug txiav txim siab, suav nroggenetic predisposition, raug tshuaj lom neeg , the ionizing radiation , the oncogenic virus , kev tswj hwm tshuaj tiv thaiv lossis tshuaj [1].
Qee cov kev tshawb fawb qhia tias qhov ntev ntev ntawm cov dev mus rau haus luam yeeb yuav ua rau muaj kev loj hlob ntawm tus kab mob, vim nicotine nws ua rau kom cov kab mob. Kev loj hlob ntawm primitive endothelial hlwb nyob rau hauv ntau yam qauv ntawm angiogenesis. Peb tham txog nws hauv kab lus no: "Kev haus luam yeeb cuam tshuam rau tsiaj li cas?"
Hemangiosarcoma cov tsos mob hauv dev
Cov tsos mob tshwm sim hauv tus dev nrog hemangiosarcoma feem ntau muaj feem cuam tshuam rau qhov chaw ntawm lub hauv paus ntawm cov qog thawj zaug thiab seb puas muaj metastases. Nyob rau hauv cov ntaub ntawv ntawm rupture ntawm lub neoplasm, tus tsiaj tej zaum yuav tshwm sim loj heev nyob rau hauv hemorrhage, pom los ntawm tus neeg saib xyuas los ntawm cov tsos mob ntawm lub plab hnyuv thiab manifestations txuam nrog mob hemorrhage (paj mucosa, tachycardia thiab tachypnea), ntxiv rau lwm yam tsos mob xws li lethargy, kev nyuaj siab, anorexia, poob phaus, palpable plab plab, qoj ib ce intolerance, thiab poob siab. Kev tuag los ntawm kev poob siab hypovolemic (poob dej ntau thiab ntshav) kuj tuaj yeem tshwm sim.
Primary pob txha hemangiosarcomas hauv dev yog qhov tsawg heev, nrog rau qhov tshwm sim tsawg dua 5%, thiab ntau zauscuam tshuam cov pob txha ntev , xws li humerus, femur, tav thiab vertebrae, thiab pob txha tawg tuaj yeem tshwm sim hauv cov chaw no [2]
Kev loj hlob ntawm cutaneous hemangiosarcoma nyob rau hauv dev feem ntau tshwm sim nyob rau hauv lub ventral plab cheeb tsam, nraub qaum, taub hau, caj dab thiab nyob rau hauv lub scapular, axillary, inguinal, thiab medial cheeb tsam ntawm lub femur (puab ncej puab). Cov qog nqaij hlav nrog lub ntsej muag los yog masses nrog cov xim liabthiab ib qho ruaj khov tshwm sim. Cov duab hauv qab no qhia tau hais tias tus kab mob hemangiosarcoma hauv tus dev:
Diagnosis of Hemangiosarcoma in Dogs
Kev txheeb xyuas tus kab mob yuav tsum ua los ntawm tus kws kho tsiaj, uas yuav ua rau kuaj thiab kuaj cov duab. Kev kuaj pom tseeb ntawm hemangiosarcoma splo yog tsim los ntawm histopathological kuaj (biopsy lossis qog excision).
Feem ntau, kev kuaj mob ntawm cov neeg mob hemangiosarcoma tau qeeb thaum cov qog tau nce mus txog qhov loj me, vim tias cov tsos mob tshwm sim tsis yog qhov tshwj xeeb [1].
Thiab rau Hemangiosarcoma hauv dev
Kev kho mob ntawm hemangiosarcoma yog nyob ntawm nws theem, uas yog, nyob rau theem ntawm kev loj hlob ntawm cov qog, ntawm kev koom tes ntawm cov qog ntshav qog thiab cov tsos mob ntawm metastases. Qhov tag nrho tshem tawm cov qog thawj zaug yog lub hom phiaj tseem ceeb ntawm kev kho mob, nrog rau lub hom phiaj ntawm kev tso cai rau kev kho mob ntau dua. Thaum xub thawj, txawm li cas los xij, kev ruaj khov ntawm tus tsiaj los ntawm kev poob siab, ua tib zoo soj ntsuam kev kuaj ntshav, thiab kho cov coagulation abnormalization yog tsim nyog. Kev phais yuav tsum tau ua kom tshem tawm tag nrho cov ntaub so ntswg, tshwj xeeb tshaj yog nyob rau hauv cov neeg mob ntawm cutaneous hemangiosarcomas. Hmoov tsis zoo, vim yog kev loj hlob sai ntawm metastases, txoj kev phais feem ntau tsis cuam tshuam nrog lub neej expectancy ntawm tus tsiaj cuam tshuam thiab kev kho mob thiab tshuaj tiv thaiv kab mob siv tau
Tshuaj kho mob tuaj yeem ua kom lub neej ntev ntawm cov dev, ua kev kho mob palliative, tsom rau kev zam thiab / lossis kev nplij siab ntawm tus tsiaj, txhim kho nws lub neej zoo thiab txo cov tsos mob ntawm metastasis lossis qog nqaij hlav uas tsis muaj lawm. tuaj yeem cuam tshuam.
The acupuncture, txuam nrog rau lwm yam kev kho mob xws li cov uas tau hais, tau pom tau hais tias txaus siab, txhim kho cov kev noj qab haus huv ntawm tus tsiaj, ncua sij hawm. qhov evolution ntawm mob qog noj ntshav thiab nce lub neej expectancy, ntxiv rau kev txaus siab rau lub rebalancing ntawm cov kab mob [2] Txawm li cas los xij, nws yuav yog tus kws kho tsiaj uas tuav rooj plaub. leej twg txiav txim siab seb hom kev kho mob no puas yooj yim los tsis yog.
Life expectancy of a aub with hemangiosacroma
Lub neej ntawm tus dev cuam tshuam los ntawm hemangiosarcoma is variable heevthiab yuav nyob ntawm tej yam xws li: tus yam ntxwv ntawm tus dev, qhov loj ntawm cov qog, yog tias nws ua haujlwm tau, yog tias muaj metastases thiab cov kabmob uas cuam tshuam. Qhov kuaj pom ua ntej, qhov zoo dua qhov kev kho mob thiab kev ciaj sia ntev rau tus dev.
Tam sim no koj paub tias hemangiosarcoma hauv dev yog dab tsi, nws cov tsos mob thiab qhov tshwm sim, tsis txhob yig mus rau qhov chaw kho tsiaj yog tias koj pom cov cim ceeb toom. Nco ntsoov tias qhov kev ua sai sai yog qhov tseem ceeb hauv qhov pathology no. Tsis tas li ntawd, tsis txhob nco cov kab lus no txog Hom mob qog noj ntshav hauv cov dev kom kawm paub txheeb xyuas lawv li cas.
