Embolization of Wide Neck Cerebral Aneurysms using pConus Stent ? Our Experience

Bifurcation aneurysms with wide neck present a challenge to the traditional endovascular procedures even nowadays. (1) Various modified endovascular approaches are being used to maintain the patency of vital artery vessels and to stabilize the web of coils, placed into the aneurysm. The most commonly used methods in treating this type of aneurysm are stent-assisted coiling, balloon-assisted coiling, use of two stents in Y configuration, double micro-catheter technique, etc. (2-5) A new device type for endovascular treatment of this pathology is the aneurysmal stent pCONus (phenoh, Bohum, Germany). It has been recently developed deliberately to enhance the safety of endovascular treatment in this aneurysm type and comes as a reliable alternative to Y stenting and balloon-assisted coiling in the majority of cases. (6-7) The pCONus implant is in fact a stent like intracellular device for wide neck intracranial aneurysm management. It is designed so that via its most distal segment to allow the stable placement of coils in complex aneurysms creating mechanical barrier at the level of the aneurysmal neck, while the most proximal segment or its intracellular portion acts like an anchor and keeps the stent in the afferent arterial vessel.
