The efficacy and safety of transvenous embolisation in the treatment of intracranial dural arteriovenous fistulas.

Abstract

To evaluate the role of transvenous embolisation including its efficacy and safety in the treatment of intracranial dural arteriovenous fistulas (DAVFs), we retrospectively analysed seven cases of intracranial DAVFs treated with transvenous embolisation in combination with arterial embolisation. Four DAVFs were in the cavernous sinus, two in the transverse-sigmoid sinus, and one in the inferior petrosal sinus. The transarterial and transvenous embolic agents included fibred platinum coils (FPC) and interlocking detachable coils (IDC). In all patients, the transarterial embolisation alone had failed to cure the DAVFs. After the combined transvenous embolisation, the anatomical cure was proven in five patients, and all patients were clinically cured. There were no complications in any patient. In conclusion, the transvenous embolisation is a useful and safe approach in the management of intracranial DAVFs.
