Cerebrospinal fluid Leakage, Elective posterior fossa surgery


Objective:  This descriptive case series anticipated to explore the occurrence and related factors of CSF leaks in patients undergoing elective posterior fossa surgery, highlighting on identifying possible risk factors and exploring treatment modalities.

<Materials & Methods:  Included 97 patients undergoing elective posterior cranial fossa surgery at Lady Reading Hospital, Peshawar, from July 2021 and January 2022. Thorough patient demographics, surgical indications, and outcomes were precisely documented and investigated.

Results: 70 patients experienced symptoms for one month or fewer, whereas 27 patients underwent symptoms for longer durations, emphasizing a predominant manifestation of short-term symptoms. 43 patients had a BMI of 27 Kg/m2 or less, even though 54 patients had a BMI exceeding 27 Kg/m2. With reference to patients with diabetes mellitus, 17 patients were diabetic, with the bulk, comprising 80 patients, being non-diabetic. 20 patients were hypertensive, while 77 patients were non-hypertensive. 46 patients were diagnosed with hydrocephalus, while 51 patients showed symptoms related to loss of consciousness. The study established that 15% of patients experienced CSF leaks postoperatively, with males including a greater proportion of affected individuals. Conclusion:  The results highlight the significance of comprehensive preoperative assessments and surgical techniques to minimize the risk of CSF leakage. Whereas conservative methods such as re-suturing the wound and CSF lumbar drainage were first employed, surgical repair became compulsory in some cases. This exploration offers a valuable understanding of the incidence and management of CSF leaks succeeding posterior fossa surgery, proposing guidance for healthcare professionals in elevating patient outcomes.
