Abstract
Slow-flow vascular malformations (VM) can be associated with localized intravascular coagulopathy (LIC) that is characterized by elevated D-Dimer levels and low fibrinogen and platelets. This can lead to bleeding and clotting tendencies, which can give rise to functional limitations such as pain and swelling and even progress to disseminated intravascular coagulopathy. We conducted a chart review of four patients with evidence of LIC who were started on rivaroxaban. We found an improvement of D-Dimer and/or fibrinogen levels in all four patients. They also had an improvement of pain and functionality. We report on four patients in whom anticoagulation with a direct oral anticoagulant, rivaroxaban, was effective in controlling signs and symptoms of consumptive coagulopathy with no evidence of bleeding from the use of rivaroxaban.
