STUDY DESIGN: A retrospective analysis. OBJECTIVE: To evaluate the association between early postoperative dural sac cross-sectional area (DCSA) and @entity158 . SUMMARY OF BACKGROUND DATA: The correlation between postoperative magnetic resonance imaging (MRI) findings and postoperative @entity16 after lumbar decompression surgery is controversial. METHODS: This study included 115 @entity1 who underwent lumbar decompression surgery followed by MRI within 7 days postoperatively. There were 46 @entity1 with early @entity282 , regardless of whether the @entity158 was mild or similar to that before surgery. The intervertebral level with the smallest DCSA was identified on MRI and compared preoperatively and postoperatively. Risk factors for @entity282 were determined using univariate and multivariate analyses. Subanalysis according to absence/presence of a residual suction drain also was performed. RESULTS: Multivariate regression analysis showed that smaller postoperative DCSA was significantly associated with early @entity282 (per -10 mm; odds ratio, 1.26). The best cutoff value for @entity158 was early postoperative DCSA of 67.7 mm. Even with a cutoff value of <70 mm, sensitivity and specificity are 74.3% and 75.0%, respectively. Early postoperative DCSA was significantly larger before suction drain removal than after (119.7  10.1 vs. 93.9  5.4 mm). CONCLUSIONS: Smaller DCSA in the early postoperative period was associated with @entity158 after lumbar decompression surgery. The best cutoff value for @entity282 was 67.7 mm. Absence of a suction drain at the time of early postoperative MRI was related to smaller DCSA.
