Summary
Iatrogenic dural tears occurred in 3.9% of lumbar surgeries. Secondary surgeries doubled the risk, increasing surgery time and hospital stay for patients experiencing this complication.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Surgical Complications
Background:
- Iatrogenic dural tears with cerebrospinal fluid leakage are known complications of lumbar spine surgery.
- Reported incidence in the literature ranges from 3% to 16%.
Purpose of the Study:
- To determine the incidence of iatrogenic dural tears during lumbar neural decompressive surgery.
- To identify risk factors and outcomes associated with dural tears.
Main Methods:
- Retrospective review of 634 patient records undergoing lumbar neural decompressive surgery between September 2007 and June 2008.
- Data collected included surgeon-documented dural tears, patient demographics, surgical details, and length of stay.
Main Results:
- The overall incidence of dural tear was 3.9% (25 out of 634 operations).
- Secondary surgeries had a significantly higher risk (7.9%) compared to primary surgeries (3.3%).
- Patients with dural tears were older (mean 65.9 vs 58.1 years), surgery duration was longer (72 vs 56 minutes), and length of stay increased by 1.1 days.
Conclusions:
- The incidence of iatrogenic dural tear in this cohort was 3.9%.
- Secondary surgery significantly increases the risk of dural tears.
- Dural tears are associated with prolonged surgery and increased hospitalization.
