Injury to the vertebral artery during anterior cervical discectomy is rare but potentially fatal. We report a case of cerebellar infarction after endovascular embolization for iatrogenic vertebral artery injury at C5-C6 during an anterior cervical discectomy and fusion. A 61-year-old man had an intraoperative injury of the right vertebral artery that occurred during anterior cervical discectomy and fusion at C5-C6. Hemorrhage was not controlled successfully by packing with surgical hemostatic agents. While the patient was still intubated, an emergency angiogram was performed. The patient underwent endovascular occlusion of the right V2 segment with coils. After the procedure, his course was uneventful and he did not show any neurologic deficits. Brain computed tomographic scans taken 3 days after the operation revealed a right cerebellar infarction. Anti-coagulation medication was administered, and at 3-month follow-up examination, he had no neurologic sequelae in spite of the cerebellar infarction.
Key Words: Cervical discectomy; Vertebral artery injury; Endovascular occlusion; Cerebellar infarction
