pCONus is a stent-like endovascular device which aids in retention of coils within wide-necked bifurcation aneurysms. It is retrievable even after complete deployment and is detached electrolytically. The pCONus aided coiling of wide-necked bifurcation aneurysms has a high technical success rate and a good safety profile. Different complications have been described in literature with the usage of pCONus. This case report describes a unreported complication of inappropriately deployed pCONus device.
