While the prevailing thought has been that aneurysms are congenital (meaning that people are born with them), it is now thought that they are due to microscopic damage to the artery walls caused by abnormal flow at the junction points where the arteries come together.
Kuigi valdav mõte on see, et aneurysms on kaasasündinud (mis tähendab, et inimesed on sündinud nendega), see on nüüd arvasin, et need on tingitud mikroskoopilise kahju arteri seinte põhjustatud ebatavalise voolu ristmikul punktid, kus arterid kokku.
