Percutaneous CT-guided facet joint synovial cyst rupture: Success with refractory cases and technical considerations.

Overview

Percutaneous image-guided rupture of lumbar facet synovial cysts can improve clinical outcomes and obviate the need for open surgery. This series describes eleven patients who had successful CT-guided lumbar facet synovial cyst ruptures, 82% of which experienced excellent pain relief at a minimum of one-year follow-up. Of the five patients who failed prior fluoroscopic-guided synovial cyst rupture, 80% had a successful CT-guided rupture and one-year sustained pain relief. These findings reinforce minimally invasive CT-guided treatment as an excellent option to improve patient symptoms and potentially avoid open surgery.
