“…Other suggested risk factors are certain drugs and blood products, such as hepatitis B immunoglobulin [24,31,34], the combination of aprotinin and octreotide [37], solvent-detergent plasma [36], and large volumes of cryoprecipitate, fresh frozen plasma or platelet concentrates [20,21,23]. The potential role of acquired and congenital thrombophilia disorders, such as protein C, protein S, or antithrombin III deficiencies or factor (F) V Leiden mutation, has been investigated in only a small number of patients [17,27,29,32]. However, in general, FV Leiden is not associated with an increased risk of PE for surgical patients, and congenital thrombophilia disorders are thought to play only a minor role in the development of thromboembolic complications in these patients [57,58].…”
