Final answer:
Cerebral edema is the condition that occurs when changes in capillary endothelial tissue permeability allow plasma to seep into the extracellular spaces, typically in the context of a hemorrhagic stroke.
Step-by-step explanation:
The complication that results from changes in capillary endothelial tissue permeability, allowing plasma to seep into the extracellular spaces, is cerebral edema. This condition is often associated with hemorrhagic strokes, where a damaged blood vessel leads to bleeding in the brain. As the blood accumulates, it raises the pressure within the cranial vault, causing tissue damage and leading to the breakdown of the blood-brain barrier. This breakdown permits additional fluid to accumulate in the region, resulting in edema.
