No. Spinal fluid leaks are unfortunately one of the many risks of spine surgery and is not typically considered to be the fault of a surgeon. The important thing is that one is diagnosed and properly treated.
Vague ?? but no. What kind of surgery are you referring to? With many neurosurgical procedures, CSF leak is a risk, especially if the CSF space itself was entered as a part of the operation. These leaks are not uncommon, sometimes even a normal part of healing, and usually resolve with proper treatment. I encourage you to review your concerns with your surgeon. Your surgeon is in the best position to help you.
