Objectives
To characterise the safety, efficacy and cost of direct carotid-cavernous fistula (CCF) treatment using polyvinyl alcohol copolymer or detachable balloons.
Methods
We reviewed retrospectively patients with direct CCFs treated with either a detachable balloon or polyvinyl alcohol copolymer at our hospital from 2005 to 2015 and identified 94 patients with 105 CCFs. All patients had follow-up angiograms. The CCF occlusion rate, procedure complication rate, treatment expense and operation time were recorded.
Results
With a mean of 5.4 months of angiographic follow-up, the complete occlusion rate and recanalisation rate of the polyvinyl alcohol copolymer group was not significantly different from that of the detachable balloon group. The treatment expense was much higher and the operation time was much longer in the polyvinyl alcohol copolymer group than the detachable balloon group (P < 0.001).
Conclusions
Embolisation of CCF with polyvinyl alcohol copolymer is as safe and effective as detachable balloon but has a much higher cost and longer operation time.
Key Points
• Carotid-cavernous fistula results from a damaged carotid artery.
• Detachable balloons have been used with success for many years.
• Some reported excellent outcomes after embolisation with polyvinyl alcohol copolymer.
• Treatment expense is much higher in the polyvinyl alcohol copolymer group.
