The diagnosis of cerebrospinal fluid leakage after microvascular decompression surgery and management via lumbar drain

Objective: In posterior fossa surgery such as microvascular decompression (MVD), cerebrospinal fluid (CSF) leakage is a crucial problem. this study, we explored the accurate diagnosis and effective non-surgical management of postoperative CSF leakage.Methods: We reviewed 749 patients who underwent MVD from August 2018 to April 2022. Although significantly reduced problem by using triple-layer closing technique (TLCT), was still in few cases. managed these with same diagnostic flow treatment regimen lumbar drain (LD).Results: Among cohort, 11 (1.4%) had leakage, each those cases presented rhinorrhea. Five (45.5%) symptom on first day, two (18.2%) second one patient (9.1%) third three (27.3%) fifth day after surgery. After conservative including drainage via LD for 5.4 days average, none recurrent symptoms suggesting leakage; thus, there no need wound repair surgery.Conclusion: Despite diligent attempts prevent open microsurgery, leaks inevitably occur some are more frequent cannot fully should limit complication ensure that it does not progress into other severe problems, meningitis. A TLCT useful, but early also important.
