1. Reperfusion Injury: When blood flow is restored to ischemic tissues, it can lead to hemorrhage and red infarction. The influx of blood into previously ischemic tissue can cause damage and leakage of blood into the necrotic area.
2. Dual Blood Supply: Organs with a dual blood supply, such as the lungs (pulmonary and bronchial arteries) and intestines (mesenteric and collateral arteries), are more susceptible to red infarcts. If one blood supply is obstructed, the other can still deliver blood, potentially causing hemorrhage into the infarcted area.
