Y-stent-assisted coiling for large wide-neck dysplastic middle cerebral artery bifurcation aneurysm: An update to procedural technique.

ABSTRACT:

Background

The endovascular treatment of complex middle cerebral artery (MCA) aneurysms, particularly dysplastic large MCA bifurcation aneurysms, can pose significant technical challenges. We aim to present three cases illustrating the technical nuances and challenges often encountered in Y-stent-assisted coiling (Y-SAC) for such aneurysms and provide an update on technical nuances.

Methods

We present three consecutive cases of dysplastic MCA aneurysms, each >10 mm with a wide neck. We successfully performed Y-SAC in all cases on the first attempt using the "around the world" technique and used Neuroform Atlas Stent (Stryker Neurovascular, California, USA) as a distal anchor to reduce the microcatheter loop. Immediate final digital subtraction angiography showed adequate occ
