OBJECTIVE: This study is to investigate the value of intracranial venous circulation evaluation in guiding the surgery for @entity1653 . METHODS: A total of 44 @entity1653 ( @entity1653 ) @entity1 received 3D CE-MRV scanning. The obtained images were reconstructed by virtual reality (VR) technology. Venous collateral circulation was evaluated. Postoperative follow-up was carried out. RESULTS: Among 44 @entity1653 @entity1 , 41 cases were with resection of Simpson grade I/II (93.18%) and 6 cases were with permanent @entity51 (13.64%). @entity50 occurred in the remaining 3 @entity1 (6.82%), with 2 cases cured and 1 case died. The mortality rate was 2.27%. Recurrence occurred in one case (2.27%) after discharge. In 9 cases, @entity5 adjacent @entity11727 was transected and the poor prognosis rate was 33.33%. @entity11727 was opened in 3 cases and after removal of the @entity5 the broken end was sutured directly. The poor prognosis occurred in one case (33.33%). Electrocoagulation was carried out to the @entity11727 wall in 32 cases without opening venous sinus and 2 cases were with poor prognosis (6.25%). The three different venous sinus treatment methods had no significantly difference on the prognosis of @entity1 (P > 0.05). CONCLUSIONS: Preoperative evaluation of intracranial venous circulation with VR technology and 3D CE-MRV may help making individual surgical plans, reduce @entity1317 and improve the prognosis of @entity1653 @entity1 .
