A Sequela of Gastrointestinal Perforation Due to Small-Medium Vessel Vasculitis

Background: Systemic vasculitis resulting in inflammation of vessel walls may progress to ischemic damage of major dependent organs, including the gastrointestinal system. Polyarteritis nodosa (PAN) is a vasculitis that is known to present with necrotizing vasculitis in small-medium arteries, leading to life-threatening injury and surgical emergencies.
