The outcome of unilateral occipital lobectomy in 12 foetal lambs in about the 100th day of gestation: a preliminary report.
In this study occipital lobectomies were carried out on 12 foetal lambs on about the 100th day of gestation. Three lambs were born alive and had computed tomographic (CT) scans performed on the 13th or 18th day of life. One lamb was found to have hydrocephalus due to ventriculitis. All three lambs had low attenuation areas on their CT scans suggesting that scarring rather than regeneration of the cerebral tissues had taken place. There was no evidence that accelerated bone healing of the skull had occurred. It is speculated that the lack of regeneration cerebral tissues and poor bone healing may have been due to the procedure being performed at a comparatively late stage of gestation.
