The control of hemorrhage is one of the most important and yet difficult problems in all extensive craniotomies. The tourniquet, hemostatic stitch and pedicle clamp have been replaced largely by the multiple forceps method now commonly used.

This is by the use of stockinet and Michel clips. We experimented on various metal clips, but finally settled on the Michel type, for they are already available, are inexpensive, are easily applied and control hemorrhage efficiently.
