Re-treatment of an unruptured anterior communicating artery aneurysm using the new pCONus 2 device: Description of a case

Endovascular approach represents today the first option in treatment of ruptured and unruptured cerebral aneurysms. Nevertheless, wide-neck bifurcation aneurysms still represent a technical challenge for endovascular treatment due to the need to protect vessels arising next to the aneurysmal neck. A variety of devices have been implemented to ensure adequate assistance for coiling of these lesions. Among these devices, the new pCONus 2 represents an evolution of the well-known pCONus; compared to the previous one in fact, it allows a degree of articulation and flexibility between the shaft and the distal part (crown), making it more suitable for treatment of aneurysms presenting an angle between the longitudinal axis of the dome and parent vessel. We report our first case using pCONus 2 in the re-treatment of an unruptured anterior communicating artery aneurysm in a 57-year-old man, showing evident recanalization two years after coiling.
