Abstract Post-operative venous sinus thrombosis (POVST) is an uncommon complication from a craniotomy for brain tumor resection. There are few data in how to treat POVST, including the use of anticoagulation and follow-up. It has been found that POVST more common dural-based lesions especially located on or near sinus, however treatment not standardized. We retrospectively reviewed our cases between January 2018 December 2020 resection, whether we chose start not, eventual outcome. also performed literature review topic compare findings management. identified 14 POVST; 8 were extra-axial masses. Of 14, 6 had clot involving superior sagittal (SSS), with 3 being discharged direct oral anticoagulant (DOAC) one warfarin. With transverse involvement, noted (with no SSS clot), 2 started DOAC ASA 81mg. In sigmoid there did receive anticoagulation. total cases, 1 was symptomatic (new-onset seizures) necessitating surgical recanalization other symptoms attributed POVST. Two patients died unrelated reasons prior receiving any outpatient imaging, all their involved sinuses within 2-5 months. complications Our didn't show standardized method treatment. disagreement what should be used, if it necessary.
