title: Lumbar artery pseudoaneurysm after percutaneous vertebroplasty: a unique vascular complication.
abstract: Complications from percutaneous vertebroplasty (PV) and kyphoplasty are rare and are most commonly related to cement leakage. Pseudoaneurysm of the segmental arteries has not been reported as a complication of PV in the literature. In this article, the authors describe 2 patients who presented with a lumbar pseudoaneurysm after undergoing PV at other institutions. The authors also review the optimal technique to avoid such vascular complications.
