Indeed, there is a significant risk of venous migration of the embolic agent used to occlude the AV shunt, leading to a subsequent risk of nidus bleeding due to impairment (slowdown or even occlusion) of the bAVM{\textquoteright}s venous drainage.2Various endovascular techniques have been developed to avoid the risk of such inopportune impairment of the venous drainage during attempts to occlude a direct intranidal AV shunt.3{\textendash}5 We present in this Technical Video (video 1) different endovascular strategies to occlude such direct AV shunts using dual-lumen balloons with various liquid embolic agents, or using occlusion plugs.Video 1}, issn = {1759-8478}, URL = {https://jnis.bmj.com/content/early/2021/04/20/neurintsurg-2021-017317}, eprint = {https://jnis.bmj.com/content/early/2021/04/20/neurintsurg-2021-017317.full.pdf}, journal = {Journal of NeuroInterventional Surgery} }
