“…The most consistently referred advantage ( n = 24 studies) was the ability to immediately assess outcomes. Examples included confirmation of safe aneurysm clip positioning, complete obliteration of aneurysm [ 10 , 12 , 14 , 28 , 31 , 49 , 54 , 66 , 67 , 72 , 74 ] or fistulae [ 14 , 29 , 35 , 48 , 72 , 77 ], and correct screw placement [ 4 , 9 , 17 , 21 , 25 , 26 , 32 , 33 , 52 , 61 , 69 ].
