Background:
Previous findings from a clinical trial demonstrated noninferiority of Leukocyte- and platelet-rich fibrin (L-PRF) compared to commercially available fibrin sealants in preventing postoperative cerebrospinal fluid leakage, necessitating intervention. This cost-effectiveness evaluation aims to assess the value-for-money of both techniques for dural closure in supratentorial and infratentorial surgeries.
Methods:
Cost-effectiveness was estimated from a health care payer's perspective alongside a randomized clinical trial comprising 328 patients. The analysis focused on clinical and health-related quality of life outcomes, as well as direct medical costs including inpatient costs, imaging and laboratory costs, and outpatient follow up costs up to twelve weeks after surgery.
Results:
Clinical and health-related quality of life data showed no significant differences between L-PRF (EuroQol five dimensions questionnaire 0.75 ± 0.25, 36-item Short Form Survey 63.93% ± 20.42) and control (EuroQol five dimensions questionnaire 0.72 ± 0.22, 36-item Short Form Survey 60.93% ± 20.78) groups. Pharmaceutical expenses during initial hospitalization were significantly lower in the L-PRF group (€190.4, interquartile range 149.9) than in the control group (€394.4, interquartile range 364.3), while other cost categories did not show any significant differences, resulting in an average cost advantage of €204 per patient favoring L-PRF.
Conclusions:
This study demonstrates L-PRF as a cost-effective alternative for commercially available fibrin sealants in dural closure. Implementing L-PRF can lead to substantial cost savings, particularly considering the frequency of these procedures.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
