To observe the effects of the minimally invasive removal of an intracerebral hematoma on the glutamate concentration, blood-brain barrier (BBB) permeability and brain water content in the brain tissue surrounding the hematoma and to provide a theoretical basis for minimally invasive removal of intracerebral hematomas.Thirty rabbits (2.8-3.4 kg body weight) were selected to establish a model of intracerebral hemorrhage, and they were randomly divided into a model control group and a minimally invasive group after the model was prepared successfully. The intracerebral hematoma was evacuated by stereotactic procedures in minimally invasive group 6 h after the model was established. The glutamate content, the permeability of the BBB and the brain water content in perihematomal brain tissues were determined and compared between the two groups.The glutamate content, the permeability of the BBB and the brain water content in the perihematomal brain tissues were significantly decreased compared to the model control group 1, 3, and 7 days after the minimally invasive removal of the intracerebral hematoma.Minimally invasive surgery for removal of an intracerebral hematoma could significantly reduce the glutamate content, BBB permeability and the brain water content in perihematomal brain tissues.
