Analysis of 398 cases of intradural spinal tumor resection with primary dural closure: surgical outcomes based on the suture material

Cerebrospinal fluid (CSF) leak after resection of intradural spinal tumors (IST) represents a significant postoperative challenge. Although various dura suture techniques and materials have been explored experimentally, direct clinical comparative studies are lacking. This study evaluated the effectiveness of specific suture materials in primary dural closure post-IST resection and identified associated risk factors for CSF leak.
