Safety, Sequelae, and Efficacy of Nerve Root Clipping in Patients With Spontaneous Spinal Cerebrospinal Fluid Leaks.

Background And Objectives: Spinal cerebrospinal fluid (CSF) leaks may cause a myriad of clinical symptoms, the most common being orthostatic headache. Lateral leaks (Type II) and direct CSF-venous fistulas (Type III) are a subgroup of spinal CSF leaks, representing about 1/3 of spinal CSF leaks. This study aimed to analyze the risk and efficacy of nerve root clipping in patients with Type II and Type III CSF leaks.
