Study Design:
Single-center series.
Objective:
Intraspinal facet joint cysts can lead to nerve root compression symptoms with severe discomfort and disability. Permanent improvement can be achieved by surgical resection of the cyst. However, cerebrospinal fluid (CSF) leakage is a common problem in resection of facet joint cyst.The aim of the study was to investigate the frequency of CSF leak after resection of a joint cyst and to determine predictive factors.
Methods:
A total of 176 consecutive patients underwent surgery for lumbar spinal facet joint cyst in our institution between 1997 and 2018. Patients with a CSF leak were compared with patients without a CSF leak (control group).
Results:
CSF leakage occurred in 14 patients (8.0%) In 2 of the cases (14.3%), the CSF leak was recognized only postoperatively, in 12 cases (85.7%), the CSF leak was detected intraoperatively. Despite intraoperative dura repair, 4 of these 12 patients (33.3%) presented with CSF leakage postoperatively. Altogether 6 patients had postoperative CSF leakage. Compared with patients without CSF leak, there were no differences in preoperative symptoms, surgical technique, complications, or postoperative findings. Adhesion of the cyst to the dura mater was present in all 14 patients with CSF leakage (100%), but only 61.7% of the control group ( P <0.005). All patients in the CSF leak group showed an improvement of their preoperative symptoms.
Conclusions:
The rate of CSF leakage in resection of spinal facet joint cyst was 8% in the present study. The occurrence of a CSF leakage was independent of clinical factors, level, or side of the cyst, but significantly correlated to dural adhesion of the cyst.Since neither clinical recovery nor recurrence rates do depend on complete removal of the cyst, aggressive resection of dural adherend parts of the cyst wall should be avoided to prevent CSF leakage.
