Localised intravascular coagulation in a patient with venous malformations:  A case report

Venous malformations are the most frequently seen slow-flow vascular malformations. Localised intravascular coagulation (LIC) is a recognised coagulation abnormality associated with venous malformations and can cause local pain and thrombosis. Various factors, including invasive procedures, can trigger severe LIC, which can progress to disseminated intravascular coagulation (DIC). Lack of awareness about LIC, and misdiagnosis lead to poor patient outcomes. There is no published data from Sri Lanka on the management of patients with LIC. Here, we report a case of severe LIC in a patient with extensive venous malformations triggered by surgery, leading to severe bleeding that was successfully managed with heparin.
