*6.3.6 Complications of embolization*

Stroke and ICH are the most common complications of endovascular embolisation. The ischemic stroke is most likely secondary to thromboembolic complications of catheterization and nontarget embolization, while ICH may occur secondary to vascular injury or AVM rupture. Arterial feeders' injury and perforation occur when a microcatheter or wire is introduced through tiny tortuous pial arteries. Accidental closure of draining veins before elimination of the nidus during embolization may cause nidal rupture and ICH [23, 35, 36].
