Continuous cerebrospinal fluid drainage using a lumbar subarachnoid catheter for cerebrospinal fluid rhinorrhea after functional endoscopic sinus surgery

Anesthesiologists are frequently consulted for performing lumbar cerebrospinal fluid (CSF) drainage to facilitate surgery or manage complications. Functional endoscopic sinus surgery (FESS) is a common treatment for chronic sinus diseases. Cerebrospinal fluid (CSF) leakage is a serious complication following FESS and is typically treated with an endonasal free or rotational mucoperichondrial flap. Continuous drainage of CSF with a lumbar subarachnoid catheter has been used in patients who have undergone neurosurgery but it is seldom used in the treatment of post-FESS CSF rhinorrhea. We present a 71-year-old male patient who suffered from CSF rhinorrhea after FESS, and was treated successfully with continuous lumbar CSF drainage. We are of the opinion that continuous CSF drainage with a lumbar subarachnoid catheter is an effective and safe modality of treatment for post-FESS CSF leakage.
