**2.4 Targeted embolization**

Intranidal aneurysm that may cause recurrent bleeding is the main target for embolization if a complete or near complete obliteration is not feasible (**Figure 4**). Aneurysms are more frequently seen in AVMs located in the frontal and occipital lobes. Deep arterial feeders not accessible by surgery are also a good target for embolization. Obliteration of the fistulous component of an AVM and decreasing AVM size by embolization may improve the cure rates after radiosurgery.
