ABSTRACT
BACKGROUND:
The incidence of dural venous sinus thrombosis (DVST) following vestibular schwannoma (VS) surgery remains understudied. The diverse clinical presentation complicates forming anticoagulation treatment guidelines. This meta-analysis aimed to investigate the incidence of DVST post-VS surgery and to evaluate the role of anticoagulation.METHODS:
A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist, was conducted. Studies reporting DVST incidence after VS surgery were included. DVST incidence stratified by detection method was the primary outcome. Adverse events per treatment strategy (anticoagulation or no anticoagulation) were the secondary outcome. Pooled incidence with respective 95% confidence intervals were calculated using the random-effects model via the DerSimonian and Laird method.RESULTS:
The overall DVST incidence post-VS resection was 15.5% (95% confidence interval 10.3%, 22.5%; 10 studies). Stratification by detection method revealed 29.4% (19.2%, 42.3%) for magnetic resonance imaging, 8.2% (3.2%, 19.5%) for computed tomography, and 0.7% (0.2%, 2.8%) upon clinical suspicion. The pooled incidence of adverse events was 16.1% (6.4%, 35.0%) for the anticoagulation treatment and 4.4% (1.4%, 12.9%) for no anticoagulation treatment, with one mortality case being among the adverse events in this latter group.CONCLUSIONS:
DVST after VS surgery is more common than initially perceived, predominantly presenting asymptomatically. Variability in anticoagulation protocols hinders the establishment of definitive therapeutic stances; nevertheless, there is no supporting evidence to promote anticoagulation administration for DVST. This begs the need for further institutional comparative studies with a proper adjustment for confounding and well-defined anticoagulation regimens.Mots clés
