Abstract | STUDY DESIGN: Retrospective review OBJECTIVE: To determine the efficacy of management of cerebrospinal fluid (CSF) leakage after the anterior thoracic approach. SUMMARY OF BACKGROUND DATA: CSF leakage after incidental durotomy commonly occurs after anterior thoracic ossification of posterior longitudinal ligament (OPLL) surgery. Pseudomeningocele will invariably form under such circumstances. Among them, uncontrolled CSF leakage with a fistulous condition is problematic. As a solution, we have managed these durotomies with chest drains alone without any CSF drainage by the concept of a "volume-controlled pseudomeningocele." METHODS: Between 2001 and 2009, CSF leakage occurred in 26 patients (37.7%) of the total 69 patients who underwent anterior decompression for thoracic OPLL. In the initial 11 cases, subarachnoid drainage was utilized as an augmentive measure in combination with chest tube drainage in the postoperative period (group A). In the subsequent 15 cases, the durotomy was managed in a similar manner but in the absence of any subarachnoid drainage (group B). Various parameters such as the duration of postoperative hospital stay, clinical outcome score, drainage output, resolution of CSF leakage, complications, and additional surgery performed were analyzed and compared between the 2 groups. A resolution of the CSF leakage grading system was also proposed for the residual pseudomeningocele that formed in each group. RESULTS: There were statistically no significant differences in the outcome parameters between the 2 groups and also in patients with grade I or grade II residual pseudomeningocele of the new grading system. Two complications occurred in group A. No reexploration for persistent CSF leakage was required in both groups. CONCLUSIONS: CSF leakage managed with controlled chest tube drainage can produce a comparable result with those with additional subarachnoid drainage when watertight dural repair is impossible. The concept of controlled pseudomeningocele may be a useful and practical technique for the treatment of CSF leakage after anterior thoracic OPLL surgery.
