Multiple experimental and review studies confirm that macrophages and microglia actively phagocytose and clear extravasated blood cells following internal bleeding events such as intracerebral hemorrhage.
Bexarotene treatment enhances macrophage erythrophagocytosis and hematoma clearance in experimental intracerebral hemorrhage models.

The analysis
The retrieved papers consistently demonstrate across multiple models (intracerebral hemorrhage, stroke, and cardiovascular pathologies) that macrophages and microglia perform erythrophagocytosis and efferocytosis to clear extravasated blood cells and hematomas. There are no papers refuting this well-established biological function.
Efferocytosis describes the phagocytic clearance of dying cells by phagocytes, including macrophages, following cardiovascular and cerebrovascular injuries.
Microglia/macrophage-mediated erythrophagocytosis plays a crucial role in hematoma clearance and is modulated by cytoskeletal dynamics after intracerebral hemorrhage.
