Coil embolization of an appendiceal artery bleed leading to appendicitis and surgical resection

Background: Appendiceal bleeding is an infrequent cause of lower gastrointestinal bleeding (LGIB), accounting for only 0.014% of cases. Case report: We present the case of a 48-year-old male on heparin who developed an acute LGIB from the appendicular artery requiring coil embolization and subsequently developed appendicitis. Conclusion: This case highlights appendicitis as a potential complication of appendiceal artery embolization. Careful patient selection and consideration of alternative approaches, including upfront surgery or endoscopic therapy, are essential in managing appendiceal artery bleeds. LEARNING POINTS: Expands the internist's differential and management strategy for obscure lower gastrointestinal bleeding.Identifies appendicitis as a real, not theoretical, complication of appendiceal artery embolization.
