This brief technical report describes our initial experience using the FlowGuard valved introducer sheath during the insertion of tunneled hemodialysis catheters in 15 patients. The incorporation of a silicone valve into the introducer sheath is intended to minimize blood loss and decrease the risk of air embolism during the catheter insertion procedure. Our preliminary experience demonstrated that the FlowGuard sheath is a substantial improvement when compared to standard introducer sheaths. However, an asymptomatic air embolus did occur in one patient. This article describes several caveats for the use of this new product.
