Cerebrospinal fluid leak after anterior cervical discectomy, fusion rare but serious
Although uncommon, cerebrospinal fluid leak following cervical discectomy and fusion is a serious complication; however, repair is usually possible, according to study findings.
In a retrospective study, researchers reviewed case logs from 1,223 anterior cervical discectomy and fusion procedures to identify cases where cerebrospinal fluid (CSF) leaks were encountered. The researchers then determined how the leaks were managed through a review of medical records, operative reports and imaging.
Of the 1,223 anterior cervical discectomy and fusion procedures performed, 13 resulted in CSF leaks. Nine of the leaks were able to be repaired through surgery and four were treated with postoperative lumbar drainage, of which one of the cases was successful. The other three patients underwent neck re-exploration and delayed repair, according to the researchers.
In a review of the literature, the researchers found seven case reports of CSF leak following anterior cervical discectomy and fusion, and only one article reviewing the prevalence and management of this complication.
The researchers concluded that indirect repair in patients who experience this complication is usually successful; however, in the cases that are not, reoperation or lumbar drainage may be required.
