Abstract

<p>Background. Obtaining intra-operative watertight closure of the dura is considered important in reducing post-operative cerebrospinal fluid (CSF) leak. The purpose of this study was to evaluate a fibrin sealant as an adjunct to sutured dural repair to obtain intra-operative watertight closure in cranial neurosurgery. Methods. This randomized, controlled multicenter study compared a fibrin sealant (EVICEL<sup>®</sup>Fibrin Sealant [Human]) to sutured dural closure (Control). Subjects underwent supratentorial or posterior fossa procedures. Following primary dural repair by sutures, the closure was evaluated for intra-operative CSF leak by moderately increasing the intracranial pressure. If present, subjects were randomized to EVICEL<sup>®</sup>or additional sutures (2:1 ratio), stratified by surgical approach. Following treatment, subjects were successful if no CSF leaks were present during provocative challenge. Safety was assessed to 30 days post-surgery, including incidence of CSF leakage. Results. One hundred and thirty-nine subjects were randomized: 89 to EVICEL<sup>®</sup>and 50 to Control. Intra-operative watertight closure was achieved in 92.1% EVICEL<sup>®</sup>-treated subjects versus 38.0% controls: a treatment difference of 54.1% (p <0.001). The treatment differences in the supratentorial and posterior fossa strata were 49.1% and 75.7%, respectively (p <0.001). The incidence of adverse events was similar between treatment groups. No deaths or unexpected serious adverse drug reactions were reported. CSF leakage within 30 days post-operatively was 2.2% and 2.0% in EVICEL<sup>®</sup>and control groups, respectively. In addition, 2 cases of CSF rhinorrhoea were observed in the EVICEL<sup>®</sup>group. Although not associated with the suture line where EVICEL<sup>®</sup>was applied, when combined with the other CSF leaks, the observed leak rate in the EVICEL<sup>®</sup>group was 4.5%. Conclusions. These results indicate that EVICEL<sup>®</sup>is effective as an adjunct to dural sutures to provide watertight closure of the dura mater in cranial surgery. The study confirmed the safety profile of EVICEL<sup>®</sup>.</p>
