Most coil-induced aneurysmal ruptures during endovascular treatment occur in small, recently ruptured aneurysms, and after placement of at least one coil. In cases where the distal part of the microcatheter cannot move back due to its straightness and tightness, the last coil deployed may advance towards the aneurysmal wall through intercircles of deposited coils. To solve this problem, after complete occlusion of the sac is obtained, the microcatheter is slightly. withdrawn until the tip of the catheter is placed in the neck, and then the neck is occluded with the appropriate coil.
