In order for a thromboembolism to occur, some changes in the vasculature need to be present. These include disruption of endothelial integrity, disruption of flow, disruption of blood [[:Category:Haemostasis|haemostasis]] and disruption of fibrinolysis.

The incidence of thromboembolism greatly increases with certain diseases including [[:Category:Cardiovascular System - Pathology|heart disease]], neoplasia, [[:Category:Lymphoreticular and Haemoatopoietic System - Pathology|blood disorders]], parasitic diseases and [[hyperadrenocorticism]].
