Abstract

Background: Recurrent anterior communicating artery (Acomm) aneurysms pose significant challenges in management because of their complex anatomy and the repair around the previous treatment. This case report seeks to elucidate the technical points involved in coiling for a recurrent Acomm aneurysm after failed clipping and wrapping 15 years previously.

Case Summary: An elderly male had an Acomm aneurysm wrapped after failed clipping 15years ago and presented on referral for a follow-up MRA which showed an enlargement of the aneurysm, a hypoplastic left A1, a 2.0 mm right A1, and a 1.3 mm left A2. To preserve flow to the left A2, a Neuroform Atlas stent was placed from the left A2 to the right A1 and using the jailing technique, the aneurysm was coiled. A repeat DSA on table showed a well-positioned coil mass in the aneurysm and there were no intra-procedural complications.

Discussion: Despite the small size of the left A2, we were able to successfully deploy a 3.0x20 mm stent into it, without intra- or post-procedural complications as also attested to by other authors.

Conclusion: Appropriate stent size is important in preventing some intra-procedural complications such as in-stent thrombosis. This report shows that careful case selection in situations of limitation of stent sizes can still produce excellent results.
