Effects of Pretreatment of the Dorsal Meningovertebral Ligaments on the Incidence of Intraoperative Cerebrospinal Fluid Leakage: A Comparative Study

Abstract

Cerebrospinal fluid leakage can lead to postoperative refractory headaches and meningitis. Dural injury is the main cause of postoperative cerebrospinal fluid leakage. Previously, we performed a comprehensive anatomic study on the dorsal meningovertebral ligaments in the lumbosacral regions and concluded that these ligaments are an anatomic factor leading to dural laceration. However, no clinical study has examined the relationship between dorsal meningovertebral ligaments and the incidence of intraoperative cerebrospinal fluid leakage. The goal of this study was to investigate the effect of prophylactic intraoperative pretreatment of the meningovertebral ligaments on the incidence of cerebrospinal fluid leakage during surgery.
