Te whai māramatanga ki ngā puketoto
Prototype testing of blood clot analogues in laboratory conditions (top) with flow visualisation of the velocity field using particle image velocimetry (middle), and a close-up of a deformed clot from a numerical simulation (bottom). Flow is from left to right, and the quickest flow is shown in yellow (narrowest region above the clot; image supplied).
Ka whakawhanake tēnei rangahau i tō tātou mōhio ka pēhea ngā puketoto i ō tātou ia toto, ā, ka pēhea tana tipu mā roto i te wā. DVT, ko te nohoanga o te puketoto i tētahi ia-auraki hōhonu (kei ngā waewae i te nuinga o te wā), he rary mō tētahi ka roa tana noho tekoteko mō te wā roa; hei tauira, i tētahi rerenga tino-roa, he haerenga rānei ki te hōhipera kua takaroa. He mea patu te ora o te tangata tēnei matetoto, ā, kāore pea e kitea he tohumate ōu. Ko te puketoto tētahi āhuatanga tino nui mō te tukanga mahu, engari ka parematatia ngā raru nā te tūnga, me te aha ka hua mai pea ētahi mate. Ngā puketoto, arā ko te DVT, ka kitea rawatia i te hunga kaumātua, ka mutu, he taumahatanga ōhanga ka pā ki te pūnaha hauora, ka whakahāweatia hoki te kounga o te ora. E mea ana mātou kia whaihanga i te takoto me te tipu o te thrombi i ngā ia-toto, ā, ka whakatauritea, ka whakamanahia hoki ā tātou kitenga ki ngā whakamātautanga ā-roto me ērā ka mahia e ō tātou kaihāpai, he whare ōna kāore i tua atu mō te whakaahua i ngā rauropi. I tā mātou kaupapa tono, ka whakamahia tēnei raraunga whakamātau e pā ana ki ā mātou whaihanga kia tātari ai i te tipu me ngā āhuatanga pūhanga o te thrombi. Ka kino whakamate nei pea te thrombi, ka maunu ana ia i te pakitara o te ia-toto, ka rere mā te au toto ki ngā pūkahukahu, ka purua e mōhio nei ko te pulmonary embolism. Mā te mārama ki ngā āhuatanga pūhanga me te urupare o te thrombi ka taea e ngā rata te whakapae mēnā ka purua te thrombus, kāore rānei. Ko te hua nui o tēnei rangahau ko te whakawhanaketanga mā te whakamātau o te tauira ā-rorohiko. Kua waihangatia kau noa kia matapae he pēhea te rere me te āhua o ngā puketoto, me te whāinga kia waihangatia ētahi haumanu pai kē atu mō te puketoto i te ia-auraki.
