Coil Retrieval: Stent-Assisted Retrieval Techniques

Balloon-assisted coiling was undertaken for a right MCA bifurcation aneurysm in a 45-year-old male patient. After detachment of the third coil, the fourth coil was introduced. However, there was resistance while trying to deliver the fourth coil, and the coil would neither come out of the tip of the microcatheter nor could be with drawn into the microcatheter. Therefore, the microcatheter had to be pulled back. During the process, the previous coil tip was noted to be stuck to the tip of the microcatheter. Therefore, the microcatheter along with the previous coil attached to the tip of the microcatheter was gradually withdrawn into the distal end of the guiding catheter (Fig. 52.1).
