Cov kev tshawb fawb tau pom tias cov dav hlau, tsheb ciav hlau, tsheb npav lossis tsheb neeg caij tsheb uas tseem zaum rau kev taug kev ntev tshaj li plaub teev muaj kev pheej hmoo siab dua rau cov hlab ntsha venous los ntawm kev ua rau cov ntshav venous mus rau stagnate, tso cai rau cov ntshav txhaws hauv cov hlab ntsha.Tsis tas li ntawd, cov neeg caij tsheb uas siv ntau lub davhlau nyob rau lub sijhawm luv luv kuj tseem muaj kev pheej hmoo siab dua, vim tias qhov kev pheej hmoo ntawm venous thromboembolism tsis ploj tag nrho tom qab qhov kawg ntawm lub davhlau, tab sis tseem siab rau plaub lub lis piam.

Muaj lwm yam tseem ceeb uas yuav ua rau muaj kev pheej hmoo ntawm venous thromboembolism thaum mus ncig, daim ntawv tshaj tawm qhia, suav nrog kev rog, siab heev lossis qis qis (siab dua 1.9m lossis qis dua 1.6m), siv cov tshuaj tiv thaiv qhov ncauj thiab kab mob ntshav hauv cov ntshav.

Cov kws tshaj lij hais tias qhov nce thiab nqis ntawm pob taws pob taws tuaj yeem ua rau cov leeg nqaij ntshiv thiab txhawb cov ntshav khiav hauv cov leeg ntawm cov leeg nqaij, yog li txo cov ntshav stagnation.Tsis tas li ntawd, tib neeg yuav tsum tsis txhob hnav khaub ncaws nruj thaum mus ncig, vim tias cov khaub ncaws zoo li no tuaj yeem ua rau cov ntshav stagnate.

Xyoo 2000, kev tuag ntawm ib tug hluas nkauj Askiv los ntawm lub davhlau ntev hauv tebchaws Australia los ntawm pulmonary embolism ua rau cov xov xwm thiab cov pej xeem mloog txog qhov kev pheej hmoo ntawm thrombosis hauv cov neeg taug kev ntev.LEEJ TWG tau tshaj tawm WHO Ntiaj Teb Kev Nyab Xeeb Kev Nyab Xeeb Txoj Haujlwm hauv xyoo 2001, nrog lub hom phiaj ntawm thawj theem yog kom paub meej tias kev mus ncig ua rau muaj kev pheej hmoo ntawm venous thromboembolism thiab txiav txim siab qhov kev pheej hmoo loj heev;Tom qab tau txais nyiaj txaus txaus, txoj kev tshawb fawb thib ob yuav tau pib nrog lub hom phiaj ntawm kev txheeb xyuas cov kev tiv thaiv zoo.

Raws li WHO, ob qhov kev tshwm sim ntau tshaj plaws ntawm venous thromboembolism yog cov hlab ntsha sib sib zog nqus thrombosis thiab pulmonary embolism.Deep vein thrombosis yog ib yam mob uas cov ntshav txhaws los yog thrombus tsim nyob rau hauv cov hlab ntsha sib sib zog nqus, feem ntau nyob rau sab ceg.Cov tsos mob ntawm cov hlab ntsha sib sib zog nqus thrombosis feem ntau yog mob, rhiab, thiab o ntawm qhov chaw cuam tshuam.

Thromboembolism tshwm sim thaum cov ntshav txhaws nyob rau hauv cov hlab ntsha ntawm cov leeg qis (los ntawm cov hlab ntsha sib sib zog nqus thrombosis) tawm thiab taug kev los ntawm lub cev mus rau lub ntsws, qhov chaw uas nws tso thiab thaiv cov ntshav ntws.Qhov no hu ua pulmonary embolism.Cov tsos mob muaj xws li mob hauv siab thiab ua pa nyuaj.

Venous thromboembolism tuaj yeem kuaj pom los ntawm kev saib xyuas kev kho mob thiab kho, tab sis yog tias tsis kho, nws tuaj yeem ua rau muaj kev phom sij rau lub neej, WHO tau hais.
