This study explores the presentation, management and outcomes of traumatic venous sinus thrombosis (VST) and identifies risk factors associated with poor outcomes.This study is a retrospective review of all patients with VST secondary to trauma who presented to a major trauma centre, between April 2015 and January 2020. VST was confirmed by CT venogram and a consultant neuroradiologist.Forty-six patients were identified (38 male), mean age of 43 (range 12-78) and median follow-up 10.2 months (range 0.7-39.1). Fifty-two percent presented as a severe traumatic brain injury, and all had an associated skull fractures overlying the sinus. Ninety-six percent had cerebral contusions, 96% had an intracranial haematoma, 91% had traumatic subarachnoid haemorrhage (tSAH) and 22% had acute cerebral infarction. Thirty-seven percent of the VSTs were occlusive. Fifty-eight percent had sustained, unprovoked intracranial pressure (ICP) spikes ( 20 mmHg). Fifty percent underwent surgical intervention-20% external ventricular drain and 46% craniotomy/craniectomy. Nine percent were treated with anticoagulation and 4% with antiplatelets, at a median of 13.5 days and 9.5 days post-injury, with no additional complications. Age 60 was associated with poor outcome (GOS of 3-5) (p = 0.0098). On follow-up CT, 52% of the VSTs remained unchanged, 29% re-canalised, 14% improved and 5% worsened, independent of treatment.This study demonstrated a higher incidence of VST in severe TBI and strong associations with skull fractures, cerebral contusions, tSAH, raised ICP and surgical intervention. Management was inconsistent, with no difference in outcome with or without anticoagulation. Larger, prospective cohort studies are needed to better understand this condition and establish evidence-based guidelines. |
