BACKGROUND: Excision of coil mass during clipping of recurrent or residual aneurysms after prior endovascular coiling is challenging. We evaluated the use of the carbon dioxide laser for safe and effective removal of coils during aneurysm surgery. Two cases are presented.
CASE DESCRIPTION: The first patient was a 56-year-old man with a previously coiled ruptured anterior communicating artery aneurysm. Angiography at 3-year follow-up showed recurrent aneurysm, which could not be coiled again owing to technical reasons. An aneurysm clip could not be safely applied owing to the weight of the coil mass compromising the parent vessel lumen. Laser-assisted coil mass resection was performed before permanent clip application. Intraoperative cerebral angiography showed complete obliteration of the aneurysm. The second patient was a 69-year-old woman with a previously coiled unruptured middle cerebral artery aneurysm. Angiography at 2-year follow-up showed recurrence of the aneurysm, which could not be coiled again owing to technical reasons. Laser-assisted coil mass resection was performed before the aneurysm was safely clipped. Intraoperative angiography showed complete obliteration of the aneurysm. No complications occurred using the carbon dioxide laser. At 1-year follow-up, both patients were asymptomatic with no evidence of aneurysmal recurrence.
CONCLUSIONS: Excision of coil mass is required while treating recurrent and/or residual intracranial aneurysms that were previously treated by endovascular technique. The use of carbon dioxide laser assistance while retrieving these coils is safe and effective.
