BACKGROUND: During transsphenoidal surgery for pituitary adenomas with large suprasellar extension, cerebrospinal fluid (CSF) leakage commonly develops from a defect at the arachnoid recess between the resected dura margin and the anterior edge of a normal pituitary gland (type 1 CSF leakage).
OBJECTIVE: To evaluate the usefulness of a direct suture technique of the normal gland edge on the incised dural margin to repair intraoperative CSF leakage from the arachnoid recess.
METHODS: Between November 2005 and December 2012, 861 patients with pituitary adenomas were operated on with transsphenoidal surgery, and intraoperative CSF leakage was encountered in 432 patients. Type 1 CSF leakage developed in a total of 122 patients, and their defects were repaired with the direct suture technique in 51 patients, whereas a fleece-coated fibrin glue patch alone was applied onto the defect in the other 71 patients. This direct suture technique required an additional 5 to 20 minutes in most cases.
RESULTS: We experienced no case of postoperative CSF rhinorrhea in the 51 patients whose defects were repaired by the direct suture technique and only 1 case of CSF rhinorrhea in 71 patients whose defects were repaired with a fleece-coated fibrin glue patch alone. There was no statistical difference in the outcome between 2 groups. Postoperative lumbar CSF drainage was not performed in any case.
CONCLUSION: Our 2 different repair techniques for arachnoid recess tears are very reliable methods for managing this type of CSF leakage. The direct suture technique may be more appropriate for type 1 CSF leakage with a wider gap and more prominent CSF leakage.
