Experimental subarachnoid hemorrhage (SAH) was induced in adult rabbits by three repeated cisterna magna injections of autologous nonheparinized blood. One week after the last blood injection the animals were sacrificed and examined for morphological change. No vasculopathy was noted in the basilar arteries and no periarterial thrombus was seen around the majority of these arteries. Gross and microscopic changes were observed in both the ventricles and choroid plexus. Ventricular changes included dilation of the lateral ventricles, destruction of ciliated ependymal cells, and deposition of small amounts of blood throughout the ventricular system. These ventricular changes are similar to the pathological sequelae of SAH in patients. Choroid plexus changes included electron-dense cytoplasmic inclusions and dilation of the lateral and subcellular spaces. The ventricular surface and the choroid plexus are both affected by the intracisternal injection of blood. The hydrocephalus that follows SAH may be potentiated by ependymal disruption and loss of ciliated activity in the ventricles. Changes in choroid plexus function may also occur.
