Ucwaningo luye lwabonisa ukuthi abagibeli bezindiza, isitimela, ibhasi noma izimoto abahlala phansi ohambweni olungaphezu kwamahora amane basengozini enkulu yokuthola i-venous thromboembolism ngokubangela ukuba igazi lemithambo lime, okuvumela ukwakheka kwamahlule egazi emithanjeni. Ngaphezu kwalokho, abagibeli abathatha izindiza eziningi ngesikhathi esifushane nabo basengozini enkulu, ngoba ingozi ye-venous thromboembolism ayinyamalali ngokuphelele ngemva kokuphela kwendiza, kodwa ihlala iphezulu amasonto amane.

Kunezinye izici ezingase zandise ingozi ye-venous thromboembolism ngesikhathi sohambo, umbiko uphakamisa, okuhlanganisa ukukhuluphala, ukuphakama okuphezulu kakhulu noma okuphansi (ngaphezu kuka-1.9m noma ngaphansi kuka-1.6m), ukusetshenziswa kwezithibela-nzalo zomlomo kanye nesifo segazi esizuzwe njengefa.

Ochwepheshe basikisela ukuthi ukunyakaza kweqakala lonyawo phezulu naphansi kungavivinya imisipha yethole futhi kukhuthaze ukugeleza kwegazi emithanjeni yemisipha yethole, ngaleyo ndlela kuncishiswe ukuqina kwegazi. Ngaphezu kwalokho, abantu kufanele bagweme ukugqoka izingubo eziqinile lapho besohambweni, njengoba izingubo ezinjalo zingabangela ukuthi igazi liqine.

Ngo-2000, ukufa kowesifazane osemusha waseBrithani ogibele indiza ende e-Australia ngenxa ye-pulmonary embolism kwadonsela ukunaka kwabezindaba nomphakathi engcupheni ye-thrombosis kubahambi abahamba ibanga elide. I-WHO yasungula i-WHO Global Travel Hazards Project ngo-2001, ngenhloso yesigaba sokuqala ukuqinisekisa ukuthi ukuhamba kuyayandisa yini ingozi ye-venous thromboembolism nokunquma ubucayi bengozi; ngemva kokuthola imali eyanele, kuzoqalwa ucwaningo lwesibili olunezigaba ngenhloso yokuthola izindlela zokuvimbela ezisebenzayo.

Ngokusho kwe-WHO, izimpawu ezimbili ezivame kakhulu ze-venous thromboembolism yi-deep vein thrombosis kanye ne-pulmonary embolism. I-deep vein thrombosis yisimo lapho kwakheka khona i-blood clot noma i-thrombus emthanjeni ojulile, ngokuvamile emlenzeni ongezansi. Izimpawu ze-deep vein thrombosis ikakhulukazi ubuhlungu, ukucasuka, kanye nokuvuvukala endaweni ethintekile.

I-Thromboembolism yenzeka lapho ihlule legazi emithanjeni yemilenze engezansi (kusuka ekushayweni kwemithambo ejulile) liphuka bese lihamba emzimbeni liye emaphashini, lapho lifaka khona futhi livimbele ukugeleza kwegazi. Lokhu kubizwa ngokuthi i-pulmonary embolism. Izimpawu zifaka phakathi ubuhlungu besifuba kanye nobunzima bokuphefumula.

I-WHO ithi i-venous thromboembolism ingatholakala ngokuqapha nokwelashwa kwezokwelapha, kodwa uma ingelashwa, ingaba yingozi empilweni.
