    Notes: Summary We report a case of vertebral arteriovenous fistula, in which embolization was complicated by migration of two coils and a partially inflated balloon. In order to relieve compression to the spinal cord, the displaced balloon was punctured percutaneously. For both relieving compression to the spinal cord and obliterating the residual fistula, the dislodged coils in the partially thrombosed epidural venous sinus were removed percutaneously and placed in the fistula, and more coils were implanted in the fistula percutaneously through the needle. CT follow-up half a year later showed complete resolution of compression of the spinal cord and complete recovery from myelopathy was clinically apparent.

    Notes: Abstract The discrete evasion game with a three-move lag, formulated over thirty years ago, was one of the earliest games with time-lag complications. This game remains unsolved, even though it is well-known that the game has a value. By considering the bomber-battleship duel and by constructing an explicit strategy for the bomber, we bound the value from below as 0.28648. This is believed to be the best lower bound known.
