Can we now dispense with DSA in the evaluation of aneurysm occlusion even in the most crucial first follow-up after endovascular treatment?

Endovascular embolization is nowadays the treatment of choice for many cerebral aneurysms [1 –3] but has several shortcomings. One drawback is the possibility of aneurysm recurrence with time [4,5], which occurs in about 13 to 20% of coiled aneurysms [4–6–8]. Even in aneurysms that appear completely occluded after initial endovascular coiling, aneurysm recurrence may occur as a result of coil compaction, coil migration, aneurysm growth or dissolution of an intraluminal thrombus [9–13]. Additional embolization is often possible and may prevent growth and subsequent potential subarachnoidal hemorrhage (SAH) [10,14,15].
