摘要

Objective

To introduce acellular dermal matrix (ADM) suturing as a novel repair method for intraoperative high-flow cerebrospinal fluid (CSF) leakage during transsphenoidal surgery (TSA), aiming to replace autologous fat/fascia lata grafts and reduce surgical morbidity.

Methods

Five patients (2 invasive pituitary adenomas, 2 craniopharyngiomas, 1 epidermoid cyst) underwent total sellar/suprasellar tumor resection and presented intraoperative high-flow CSF leakage. ADM grafts were tailored to dural defects and sutured directly to native dural edges. Outcomes included repair integrity, operative efficiency, and postoperative complications (CSF leakage, infection).

Results

All cases achieved dural closure without autologous tissue harvesting. Mean operative time was reduced by avoiding graft harvest procedures. No postoperative CSF leakage or intracranial infections occurred. At 30-day follow-up, all patients exhibited satisfactory recovery with stable skull base reconstruction.

Conclusion

ADM suture repair eliminates donor-site morbidity and shortens operative time while providing robust dural sealing. This technique may be a promising alternative to conventional autologous grafts for high-flow CSF leakage management, warranting larger-scale validation.
