The retrograde pressure cooker technique for transvenous embolization of a residual arteriovenous malformation following stereotactic radiosurgery.

Abstract

Residual brain arteriovenous malformations (BAVMs) following stereotactic radiosurgery are not uncommon and the optimal subsequent management remains undetermined.1-3 Endovascular embolization has been reported as an effective treatment for residual BAVMs after radiosurgery,4 5 and has the advantage over repeat radiosurgery in selected cases as angiographic weak points can be secured immediately and the risk of radiation-induced complications is less of a concern.6 7 In this technical video (video 1), we demonstrate the transvenous embolization of a previously-irradiated arteriovenous malformation and a persistent venous pouch using the retrograde pressure cooker technique, with emphasis on the important recommendations for avoiding periprocedural complications. neurintsurg;16/12/1213/V1F1V1Video 1Video demonstrating Onyx embolization of the residual brain arteriovenous malformation using the retrograde pressure cooker technique.
