In our series, the majority (92.9%) of patients with spontaneous dural sinus thrombosis had a favorable clinical outcome as defined by a mRS ≤2. Further prospective studies are needed to study the impact of anticoagulation on the clinical course of the disease.

Our primary objective was to retrospectively review our single institution experience using an anatomic multilayered repair of the retrosigmoid suboccipital craniotomy. Our secondary objective was to review the existing body of literature on the repair of this craniotomy and compare our outcomes to previous results. Retrospective review of 25 consecutive patients undergoing repair for the retrosigmoid craniotomy. University of California Davis Medical Center (2010-2016). A total of 25 consecutive patients who underwent retrosigmoid craniotomy and repair. Exclusion criteria included patients who were under the age of 18 years. Main outcomes included incidence of postoperative headache, cerebrospinal fluid leak, and wound infections. Postoperative headache was reported in two patients in this series (8%). None of thepatients in the series developed cerebrospinal fluid leak or wound infections. Mean follow-up period was 16 months. Our multilayered anatomic repair after retrosigmoid suboccipital craniotomy results in favorable clinical results and may help reduce the risks associated with this operation.
