A Cost-Effective Delivery System for FloSeal During Endoscopic and Microscopic Brain Surgery

Abstract

To share our experience with a new delivery system for the flowable hemostatic matrix, FloSeal, in endoscopic and microscopic skull base surgery. We prospectively analyzed the use of FloSeal with a hemostatic delivery system in transnasal endoscopic and microscopic skull base procedures performed at the authors' institution from January 1, 2015, to June 30, 2015. In all cases the number of aliquots was noted for the entire operation, and the total number of FloSeal ampules of 5 mL was also recorded. Our device allowed controlled application of small amounts (0.5-1 mL) of FloSeal to the site of bleeding. This controlled application resulted not only in increased visibility during its application, but it also reduced the amount of FloSeal required during the procedure. We were able to use 5-10 applications per 5-mL ampule of FloSeal within an individual procedure. No procedure required more than one 5-mL ampule of FloSeal. Therefore, the use of our device results in a reduction of costs. Prior to the use of our device, we were often only able to use 1 vial of 5 ml of material for 1 or 2 applications, especially in transnasal endoscopic procedures when working along a deep corridor. Our results indicate that our delivery device of FlowSeal can effectively control hemostasis by applying small amounts of FlowSeal to the site of bleeding. This results in increased visibility during hemostasis and a reduction of cost.
