Transforaminal epidural steroid injection and infraneural approach

Transforaminal epidural steroid injections are a common intervention in the treatment of radicular pain. Complications are rare, but can be catastrophic. One of the potentially devastating complications is occlusion of the artery of Adamkiewicz (AKA). This report is a description of an approach to avoid the complication of injury to the AKA related to transforaminal epidural injection. A 71-year-old male patient presented at the clinic with radiculopathy secondary to lumbar disc hernia. A transforaminal epidural steroid injection was planned. After a radiocontrast injection, vascular filling was detected. The needle was repositioned and an inferior entrance to the epidural space was used. No vascularity was seen and dexamethasone was administered to the patient. A transforaminal epidural steroid injection is an effective interventional treatment for radicular pain, but it requires careful attention due to the possible complications. The AKA was located in the upper half of the foramen. Keeping the wide variation in the anatomy of the AKA in mind is very important in order to prevent spinal cord ischemia.
