One commonly used commercial product as adjunct for dural closure is the collagen-bound fibrin sealant TachoSil\u00ae. We analysed whether the addition of TachoSil has beneficial effects on postoperative complications and outcomes. Our prospective, institutional database was retrospectively queried, and 662 patients undergoing craniotomy were included. Three hundred fifty-two were treated with dural suture alone, and in 310, TachoSil was added after primary suture. Our primary endpoint was the rate of postoperative complications associated with CSF leakage. Secondary endpoints included functional, disability and neurological outcome. Systematic review according to PRISMA guidelines was performed to identify studies comparing primary dural closure with and without additional sealants. Postoperative complications associated with CSF leakage occurred in 24 (7.74%) and 28 (7.95%) procedures with or without TachoSil, respectively (<jats:italic>p<\/jats:italic>\u2009=\u20090.960). Multivariate analysis confirmed no significant differences in complication rate between the two groups (aOR 0.97, 95% CI 0.53\u20131.80, <jats:italic>p<\/jats:italic>\u2009=\u20090.930). There were no significant disparities in postoperative functional, disability or neurological scores. The systematic review identified 661 and included 8 studies in the qualitative synthesis. None showed a significant superiority of additional sealants over standard technique regarding complications, rates of revision surgery or outcome. According to our findings, we summarize that routinary use of TachoSil and similar products as adjuncts to primary dural sutures after intracranial surgical procedures is safe but without clear advantage in complication avoidance or outcome. Future studies should investigate whether their use is beneficial in high-risk settings.<\/jats:p>","DOI":"10.1007\/s10143-022-01886-1","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T08:03:03Z","timestamp":1667376183000},"page":"3779-3788","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Collagen-bound fibrin sealant (TachoSil\u00ae) for dural closure in cranial surgery: single-centre comparative cohort study and systematic review of the literature"],"prefix":"10.1007","volume":"45","author":[{"given":"Alessandro","family":"Carretta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirka","family":"Epskamp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linus","family":"Ledermann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor E.","family":"Staartjes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian C.","family":"Neidert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Regli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin N.","family":"Stienen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,11,2]]},"reference":[{"key":"1886_CR1","doi-asserted-by":"publisher","first-page":"52","DOI":"10.3171\/jns.2007.106.1.52","volume":"106","author":"GR Cosgrove","year":"2007","unstructured":"Cosgrove GR, Delashaw JB, Grotenhuis JA, Tew JM, Van Loveren H, Spetzler RF, Payner T, Rosseau G, Shaffrey ME, Hopkins LN, Byrne R, Norbash A (2007) Safety and efficacy of a novel polyethylene glycol hydrogel sealant for watertight dural repair.
