Israeli doctors separated heads of one year old cojoined twins , a rare condition called craniopagus twins.  Their heads were attached at the back.  Dozens of staff members were involved in the 12 hour proceedure.  3D modeling, virtual reality and special monitoring devices were brought to the hospital especially for the proceedure.  50 professionals were on call to be ready for the operation.  After the sepatation of the blood vesels was successful, the bones were separated.  The doctors then split into two teams working in parallel in two separate operating rooms, performing a reconstruction of the scull of each of the girls and closing the skin.  They continue to be closely monitored.  It was a first for Israel!  GOD BLESS ISRAEL
