Kua whakaatuhia e ngā rangahau ko ngā pāhihi o te waka rererangi, te tereina, te pahi, te motuka rānei e noho ana mō te haerenga neke atu i te whā hāora, he nui ake te mōrearea ki te venous thromboembolism mā te mea ka noho tonu te toto o te uaua, ka puta ai he toto totoka i roto i ngā uaua. Hei tāpiri, ko ngā pāhihi e rere ana i ngā rerenga maha i roto i te wā poto he nui ake hoki te mōrearea, nā te mea kāore te mōrearea o te venous thromboembolism e ngaro katoa i muri i te mutunga o te rerenga, engari ka noho teitei tonu mō ngā wiki e whā.

E ai ki te pūrongo, tērā atu anō ngā āhuatanga ka piki ake ai te mōrearea o te venous thromboembolism i a koe e haereere ana, tae atu ki te momonatanga, te roa tino teitei, tino iti rānei (neke atu i te 1.9m, iti iho rānei i te 1.6m), te whakamahinga o ngā ārai hapū me ngā mate toto tuku iho.

E kī ana ngā tohunga mā te nekehanga ki runga, ki raro hoki o te hononga pona o te waewae ka taea te whakakorikori i ngā uaua o te kuao kau, me te whakatairanga i te rere o te toto i roto i ngā uaua o ngā uaua o te kuao kau, ā, ka whakaiti i te toto e noho pūmau ana. Hei tāpiri, me karo te tangata i te mau kākahu piri i a ia e haere ana, nā te mea ka noho pūmau te toto i roto i aua kākahu.

I te tau 2000, i te matenga o tētahi wahine taitamariki o Peretānia i tētahi rerenga tawhiti i Ahitereiria nā te mate pūkahukahu i kukume i te aro o te hunga pāpāho me te marea ki te mōrearea o te thrombosis i roto i ngā kaihaere tawhiti. I whakarewahia e te WHO te Kaupapa Mōrearea Haere Ao o te WHO i te tau 2001, ko te whāinga o te wāhanga tuatahi he whakaū mēnā ka whakanui ake te haere i te mōrearea o te thromboembolism venous me te whakatau i te kaha o te mōrearea; i muri i te whiwhinga pūtea e ranea ana, ka tīmatahia te rangahau wāhanga tuarua me te whāinga ki te tautuhi i ngā mahi ārai whai hua.

E ai ki te WHO, ko ngā āhuatanga e rua e tino kitea ana o te venous thromboembolism ko te deep vein thrombosis me te pulmonary embolism. Ko te deep vein thrombosis he āhuatanga e puta ai he toto totoka, he thrombus rānei i roto i te uaua hohonu, i te nuinga o te wā i te waewae o raro. Ko ngā tohu o te deep vein thrombosis ko te mamae, te ngawari, me te pupuhi i te wāhi e pāngia ana.

Ka puta te thromboembolism ina pakaru te toto totoka i roto i ngā uaua o ngā pito o raro (mai i te thrombosis uaua hohonu) ka haere mā roto i te tinana ki ngā pukahukahu, ka putu ki reira ka aukati i te rere o te toto. Ka kiia tēnei he pulmonary embolism. Ko ngā tohu ko te mamae o te uma me te uaua ki te manawa.

Ka taea te kite i te thromboembolism uaua mā te aroturuki hauora, ā, ka taea te rongoā, engari ki te kore e rongoatia, ka taea te whakararu i te ora, e ai ki te WHO.
