case_images: Based on previous experience, to avoid venous sinus bleeding, we designed a longitudinal "skull bridge" to provide the support for suspending the dura to compress and stop bleeding of the superior sagittal sinus (Figures 2E, F and Supplementary Video 1).

case_images: Patient 3 (a 56-year-old woman) also suffered from chronic headache and underwent a cerebral enhanced MRI, which revealed the tumor size of 2.6 x 3.3 x 4.0 cm (Figures 3A-C). A transverse skull bridge was left to suspend the dura after an occipital and suboccipital craniotomy for protecting the transverse sinus (Figure 3D and Supplementary Video 2). Complete tumor resection, as well as patency of the sinuses, was confirmed by preoperative and postoperative head CT/CTV imaging (Figures 3E, F).
