Background: Endovascular therapy for dural arteriovenous fistulas (DAVFs) is not without any risks, although it has been generally accepted to be a safe procedure. In this paper, we report a very rare complication: metachronous DAVF around a jugular valve 4 months after transvenous embolization.
Case description: A 43-year-old woman presented with left proptosis, chemosis, and double vision. Cerebral angiography demonstrated a left cavernous DAVF. The patient's symptoms resolved almost completely after embolization with platinum coils via the superior ophthalmic vein. Four months later, angiography revealed a metachronous DAVF around a jugular valve.
Conclusion: To our knowledge, only four such cases have been reported in the literature. Careful follow-up of patients treated with transvenous embolization and accumulation of such cases are needed to understand the pathogenesis of multiple DAVFs.
