Abstract
Objective: We describe how to use different hemostasis valves to improve the operability of coil embolization for cerebral aneurysms by a single surgeon.
Methods and Results: Between October 2007 and May 2015, a single surgeon performed coil embolization for 50 cerebral aneurysms using different suitable types of hemostasis valves in guiding-catheter and microcatheter.There was no excessive bleeding from the guiding-catheter during coil insertion, and the delicate operation of microcatheter and coil insertion could be performed by both hands in all cases.
Conclusion: We performed coil insertion using the two-handed technique safely and delicately by using different suitable hemostasis valves.
