Patient 4 (tongue AVM). A) Arterial injection of the lingual artery into Envoy DA and Scepter C (arrowhead) demonstrating prominent parenchymal blush over the dorsum of the tongue (arrow) with no distinct nidus, most in keeping with a predominant low flow venous malformation. b) Pressure cooker technique with occlusion of arterial inflow using the Scepter C balloon catheter (arrowhead) with percutaneous access using a Chiba needle (arrow) and injection of 4 ml 3% liquid sodium tetradecyl sulphate. C) Unsubtracted image demonstrating embolic material in situ with stasis of flow. Envoy DA catheter (arrow) and Scepter C (arrowhead) are also visible d) Final check angiogram shows no evidence of residual venous malformation
