A novel proximal end stenting technique for assisting embolization of a complex true posterior communicating aneurysm

• We treated a wide-neck irregular posterior communicating aneurysm using an adapted stent-assisted coiling embolization technique.
• We used the proximal end of the stent for neck protection and let its flared end open into the aneurysm sac.
• Follow-up indicated that the aneurysm was stable without coil migration, although the neck of the aneurysm was only partially protected by the stent.
• This stenting technique is an option for treating wide-neck aneurysms located at the origin of a tortuous and thin vessel.

Stent-assisted coiling has been widely used for endovascular treatment in recent years with satisfying clinical outcomes. The implantation of a stent using the regular approach, however, may not be safe or effective for certain aneurysms with complex structures. In this study, we report a novel stenting technique utilizing the proximal end of the stent for assisting embolization of a wide-neck irregular true posterior communicating aneurysm. This new method is a potential treatment strategy for wide-neck aneurysms located at the origin of a tortuous and thin vessel.
