Hemorrhagic presentation without venous infarction caused by spontaneous thrombosis of developmental venous anomaly and angiographic change after treatment

摘要

Developmental venous anomalies (DVAs) have been known benign anatomical variations and generally do not cause symptoms. Although several cases of venous infarction caused by DVA thrombosis have been reported, it not common in itself. But only hemorrhagic presentation in DVA is extremely rare. We describe a case with large intracerebral hemorrhage (ICH) without venous infarction caused by DVA thrombosis and angiographic change of successful treatment. Highlights ? We report a case of hemorrhagic presentation in development venous anomaly. ? All laboratory tests for hypercoagulable state were either negative or normal range. ? Thrombosis of development venous anomaly can produce cerebral hemorrhage without venous infarction. ? Anticoagulants therapy can improve draining pattern and neurologic status of patients. ? In these cases, even if there is hemorrhage, anticoagulants may be treatment option.
