Abstract

Case:

We describe the case of a 53-year-old man who developed acute groin pain 20 days after a posterior L4-L5 interbody fusion. Despite positioning of pedicle screws within the safe zone, an L4 right lumbar artery pseudoaneurysm was found on computer tomography angiogram. Coil embolization was successfully performed.

Conclusion:

Iatrogenic lumbar artery pseudoaneurysms are a rare complication of spinal surgery. Our case is, to the best of our knowledge, the only reported case where this lesion occurred despite good positioning of the screws: It is therefore important to always suspect and exclude this complication in case of suggestive symptoms.
