Development of a dural arteriovenous fistula around the jugular valve after transvenous embolization of cavernous dural arteriovenous fistula.

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.
