A330 captain experiences failure of the landing gear to retract after takeoff followed quickly by failure of the green hydraulic system. Maintenance can offer no solution and the flight returns after burning down to landing weight. Upon touchdown the green hydraulic system restored itself to normal. Maintenance had been performed on the green system prior to departure.

Narrative:
On takeoff was unable to raise landing gear up. Shortly after that [we] got a green hydraulic pump low pressure ECAM message; both number 1 and number 2 green engine hydraulic pumps had faulted with the resulting green system hydraulic low pressure. We followed ECAM and QRH procedures and contacted dispatch on the sat phone to confer with maintenance control. As we could not restore the green hydraulic system; we informed dispatch that we would hold to burn off fuel to landing weight. On landing; green hydraulic system restored itself to normal and we taxied to gate. Maintenance had worked on the green system before departure and possibly had not bleed the system before return to service; according to them.
