CT angiography can rapidly and accurately confirm the diagnosis.Survival is associated with rapid diagnosis and surgical treatment, which involves restoring perfusion and removing necrotic bowel.Advances in imaging, operative techniques, and critical care have led to a steady decline in overall mortality.
