Abstract
Introduction: A case of lumbar artery pseudo-aneurysm after surgery for lumbar 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 a possible relationship with burst fracture or reduction maneuvers was 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 were performed. Post-operatively, a hemorrhage through surgical wound had been noticed. Pseudo-aneurysm of the lumbar artery at L3 level was diagnosed and embolisation was performed. Conclusion: This is a rare case of pseudo-aneurysm occurring in the setting of surgical stabilisation after a trauma. It was revealed by a 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.

Summary
Lumbar arteries arise from the dorsal aspect of great vessels and are committed to supplying vertebrae, para spinal and posterior abdominal muscles. They divide into 3 branches: anterior, posterior and middle. These arteries can be subject to many lesions (infections, tumors or pseudo-aneurysms...). Pseudo-aneurysms are usually met after a penetrating trauma, rarely following a blunt traumatic mechanism [1]. After surgery, delayed hemorrhage through the surgical wound was noticed and L3 lumbar artery pseudo-aneurysm was discovered and excluded. Hemostasis was achieved with gauze packing and immediately after a selective angiography was ran and showed a pseudo-aneurysm of the left lumbar artery at L3 that was immediately embolized (Figure 5).
