The management of patients with elevated intracranial pressure (ICP) requires a systematic approach. After the failure of tier zero, tier one, and tier two therapies, all potential secondary causes of elevated ICP must be reviewed. Up to 28% of patients with blunt traumatic brain injury (TBI) develop cerebral sinus venous thrombosis (CSVT), among these, patients up to 55% have occlusive thrombi. A literature review revealed a dearth of specific treatment guidelines in this scenario. Here, we present one such case of refractory elevated ICP due to occlusive CSVT secondary to skull fractures. Initial CT venogram (CTV) on admission showed an occlusive CSVT; however, subsequent CTV on the post-trauma day (PTD) 4 and 6 showed non-occlusive thrombi only. The risks of worsening acute TBI-related hemorrhage with systemic anticoagulation versus the benefit of treating an occlusive CSVT are discussed here. In cases of occlusive CSVT with refractory elevated ICP and stable intracranial hemorrhage, the benefit of anticoagulation may outweigh the overall risks of hemorrhage expansion as prolonged uncontrolled ICP elevation is inevitably fatal. In this case, anticoagulation started on PTD 6, led to the resolution of ICP elevation and an excellent outcome for the patient, who was discharged to an acute rehab center, subsequently discharged home with no residual motor deficits, and was able to resume employment. Further prospective trials are necessary to develop guidelines for the management of occlusive CSVT in patients with severe TBI and to determine which patient populations are likely to benefit from early initiation of therapeutic anticoagulation.
