During a single stroke in a patient, two pathological processes, vascular hemorrhage and infarction, can occur simultaneously or sequentially in the brain, called mixed stroke. This is mainly due to hematoma formation during cerebral hemorrhage, which compresses or obstructs the microcirculation; subarachnoid hemorrhage stimulates small arteries and capillary spasm; and cerebral vascular rupture where the distal intravascular pressure drops, blood flow decreases, and local ischemia and hypoxia. The above three conditions can lead to vascular infarction. In the case of cerebral infarction, the permeability of damaged blood vessels increases, and bleeding and a small amount of hemorrhage can occur. Therefore, vascular hemorrhage and infarction can be causal and occur one after another.
