Use of the PED in a case of coil compaction and recanalization. (a) Right ICA angiography shows coil compaction with recanalization of the aneurysm neck. (b) A 4.25 × 14 mm Pipeline classic was successfully placed across the aneurysm neck. (c) Follow-up angiography showed proper device placement with coverage of the aneurysm neck and patency of the PComA. (d) Contrast stagnation was seen within the aneurysm lumen during the venous phase. (e) Six-month follow-up angiography demonstrates residual filling of the aneurysm neck. (f) One-year follow-up angiography shows stable residual filling of the aneurysm neck. PED: Pipeline embolization device; ICA: internal carotid artery; PComA: posterior communicating artery.
