Injury of common iliac vein related to lumbar discectomy is a rare complication. We report a patient who sustained injury of common iliac vein during lumbar discectomy for extraforaminal lumbar herniated disc. In this case, she had hypovolemic shock due to massive bleeding, and underwent emergent interventional treatment and open laparatomy. Although the vascular injuries were successfully repaired, it could be a fatal complication. We report the clinical features and early management, emphasizing the need for rapid diagnosis, immediate intervention and treatment for favorable outcome.
