BackgroundInjury to cerebral venous sinuses during craniotomy procedures can cause significant blood loss or venous air embolism, potentially leading to serious morbidity or mortality. When iatrogenic sinus injuries occur, it is essential to promptly obtain hemostasis and repair the sinus defect.Case DescriptionWe report on a 43-year-old woman that sustained a transverse-sigmoid sinus injury during a retrosigmoid craniotomy for resection of a cerebellopontine angle meningioma. Sinus repair was performed using a reflected dural flap with excellent outcome.ConclusionsThe use of a reflected dural flap for closure of a widely torn sinus proved to be an effective and straightforward sinus repair strategy, with postoperative imaging demonstrating persistent patency of the sinus. The described technique may be a useful addition to any neurosurgeon's armamentarium and should be considered during cases of complex sinus injuries.Copyright © 2017 Elsevier Inc.
