Objective

To demonstrate the combined endovascular and surgical treatment of intracranial arteriovenous malformations (AVM) with the novel liquid embolic agent OnyxTM.

Methods

Between 10/2001 and 10/2003, 65 patients (pt.) with 66 AVM were treated. 53 AVM were designated to be treated by a combination of endovascular and surgical therapy, 10 by embolisation and radiation and 3 by palliative embolisation alone. We present the results of 49 AVM which were treated by embolisation and surgery.

Results

A mean of 2.6 endovascular steps were performed per pt. and 3.1 feeders were embolised. 21 AVM were located in eloquent brain areas. The mean volume of AVM was 7.5ml and that of injected OnyxTM was 3.6ml per AVM. 14 AVM were eliminated by embolisation alone and 33 by combined therapy. In 2 pt. the treatment is not finished yet. The mean occlusion rate was 89±14%. A severe deficit (mod. Rankin Scale>2) appeared in 2 pt. after embolisation, in 5 after surgery. The follow-up data after a minimum of 6 months were currently collected.

Conclusions

The use of OnyxTM allows a curative embolisation in 22% and a high nidal occlusion. Multiple penetrations of OnyxTM into the nidus from the same catheter position reduces the number of feeders to be treated before surgery and allows precise and gentle resection. The angiographic and clinical results confirm this method as a safe treatment option of intracranial AVM.
