Kafukufuku wasonyeza kuti okwera ndege, sitima, mabasi kapena magalimoto omwe amakhala paulendo wopitilira maola anayi ali pachiwopsezo chachikulu cha venous thromboembolism popangitsa kuti magazi a venous asunthike, zomwe zimapangitsa kuti magazi aziundana m'mitsempha.Kuphatikiza apo, okwera omwe amatenga maulendo angapo pakanthawi kochepa amakhalanso pachiwopsezo chachikulu, chifukwa chiwopsezo cha venous thromboembolism sichizimiririka pambuyo pa kutha kwa ndege, koma chimakhala chachikulu kwa milungu inayi.

Palinso zinthu zina zomwe zingapangitse chiopsezo cha venous thromboembolism paulendo, lipotilo likusonyeza, kuphatikizapo kunenepa kwambiri, kutalika kwambiri kapena kutsika (pamwamba pa 1.9m kapena pansi pa 1.6m), kugwiritsa ntchito njira zakulera zam'kamwa ndi matenda otengera magazi.

Akatswiri amanena kuti kukwera ndi kutsika kwa phazi la phazi kungathe kugwiritsira ntchito minofu ya ng'ombe ndikulimbikitsa kutuluka kwa magazi mu mitsempha ya minofu ya ng'ombe, motero kuchepetsa kutuluka kwa magazi.Kuonjezera apo, anthu apewe kuvala zothina poyenda, chifukwa zovala zotere zingapangitse kuti magazi aziyenda.

Mu 2000, imfa ya mtsikana wina wa ku Britain wochokera ku Australia kuchokera ku pulmonary embolism inakopa atolankhani ndi anthu kuti adziwe za chiopsezo cha thrombosis kwa oyenda maulendo ataliatali.WHO inayambitsa WHO Global Travel Hazards Project mu 2001, ndi cholinga cha gawo loyamba ndikutsimikizira ngati kuyenda kumawonjezera chiopsezo cha venous thromboembolism ndi kudziwa kuopsa kwa chiopsezo;ndalama zokwanira zitapezeka, kafukufuku wachiwiri wa A pang'onopang'ono adzayambika ndi cholinga chofuna kudziwa njira zodzitetezera.

Malinga ndi WHO, ziwonetsero ziwiri zodziwika bwino za venous thromboembolism ndizozama mtsempha wamagazi ndi pulmonary embolism.Deep vein thrombosis ndi chikhalidwe chomwe magazi amaundana kapena thrombus m'mitsempha yakuya, nthawi zambiri m'munsi mwa mwendo.Zizindikiro za deep vein thrombosis makamaka ululu, kukoma mtima, ndi kutupa m'dera lomwe lakhudzidwa.

Thromboembolism (thromboembolism) imachitika pamene magazi kuundana m'mitsempha ya m'munsi (kuchokera ku deep vein thrombosis) kumatuluka ndikuyenda m'thupi kupita ku mapapo, kumene amaika ndi kutsekereza magazi.Izi zimatchedwa pulmonary embolism.Zizindikiro zake ndi kupweteka pachifuwa komanso kupuma movutikira.

Venous thromboembolism imatha kuzindikirika ndikuwunika ndikuthandizidwa, koma ikasiyidwa, ikhoza kuyika moyo pachiwopsezo, adatero WHO.
