摘要

This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult. Moreover, during the process of creating these guidelines, it became apparent that despite solid cancers being a major underlying condition for DIC, there is a lack of high-quality research on DIC associated with solid cancers. Nevertheless, we developed recommendations for clinical questions (CQs) regarding the use of heparin and recombinant thrombomodulin. Additionally, statements concerning these five questions were provided. DIC associated with various vascular abnormalities, is characterized by hyperfibrinolytic activity and linked to underlying conditions such as aortic aneurysm, aortic dissection, vasculitis syndromes, and vascular malformations. These conditions must always be considered differential diagnoses when unexplained thrombocytopenia or bleeding tendencies are observed. Although no evidence was found to support the assignment of recommendation levels, three statements were made. However, traumatic vascular abnormalities have not been discussed in this context.
