Summary
Spinal fusion hardware near large arteries can cause dangerous aortic lacerations. If unavoidable, remove the implant after spinal fusion to prevent complications.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Neurosurgery
Background:
- Anterior spinal fusion and instrumentation are common procedures for treating lumbar burst fractures.
- Metallic implants are used to stabilize the spine during the fusion process.
Observation:
- A patient developed a severe retroperitoneal hemorrhage six weeks post-anterior spinal fusion for a second lumbar burst fracture.
- The hemorrhage was caused by an aortic laceration attributed to the metallic spinal implant.
Findings:
- The metallic implant directly caused a laceration of the aorta.
- This complication occurred six weeks after the spinal fusion surgery.
Implications:
- Placement of spinal fusion hardware in close proximity to major arteries poses a significant risk.
- Consideration should be given to removing spinal implants once spinal fusion is achieved if placed near large arteries.
- This case highlights the critical need for careful implant placement and potential prophylactic removal to prevent life-threatening vascular complications.
