Introduction: A case of lumbar artery pseudo-aneurysm after surgery forlumbar vertebra burst fracture is presented. Only two cases secondary to spinal trauma and revealed after surgery have been described in the literature. A review of literature was conducted and possible relationshipwith burst fracture or reduction maneuvers is discussed.

Case presentation: Here, we report a post traumatic lumbar burst facture with incomplete motor deficit of lower limbs after a fall. Surgical reduction and stabilization via posterior approach was performed. Post-operatively, an hemorrhage  through surgical wound had been noticed.Pseudo-aneurysm of the lumbar artery at L3 level was diagnosed and embolisation performed.

Conclusion: This is a rare case of pseudo-aneurysm occurring in the setting of surgical stabilisation after a trauma. It was revealed by an hemorrhage discovered as a late complication. We should be aware of such potential complication as a delayed post surgery event in order to adapt the care.
