[Incidental durotomy: intraoperative aid in ten steps]

Area of Science:

• Neurosurgery
• Spinal Surgery
• Microsurgery

Background:

• Incidental durotomy (ID) is a common complication during spinal surgery.
• Effective management of ID is crucial for preventing complications like cerebrospinal fluid (CSF) leaks.

Purpose of the Study:

• To evaluate the effectiveness of surgical techniques for managing incidental durotomy (ID).
• To compare the outcomes of an individual surgical technique (InT) versus a ten-step technique (10 ST) for ID closure.

Main Methods:

• Retrospective analysis of 4020 spinal surgeries with microscopic assistance.
• Evaluation of 195 incidental durotomies (IDs).
• Comparison of single-stage closure rates between InT and 10 ST, particularly in primary and revision surgeries.

Main Results:

• The overall prevalence of ID was 4.4%, with higher rates in revision procedures (14.5%).
• The 10 ST achieved 100% single-stage closure in virgin surgeries and 100% in revision surgeries after initial failures.
• The InT achieved 89.7% single-stage closure in primary and 85.7% in revision surgeries.

Conclusions:

• The ten-step technique (10 ST) is highly effective for single-stage closure of incidental durotomy (ID).
• The 10 ST shows significant improvement over the individual technique (InT), especially in challenging revision cases.
• Optimized ID management is essential for minimizing complications and improving surgical outcomes.
