Cerebral aneurysms

Case overview

Imaging identified a saccular aneurysm of the left posterior communicating artery. Under general anesthesia, EVO stent-assisted coil embolization was performed. The first coil entered the distal lobule, followed by further partial packing and partial deployment of the distal stent segment. Once packing was largely complete and the coil microcatheter had been withdrawn, stent deployment was completed.

Immediate post-procedure angiography showed no opacification of the aneurysm, with preserved opacification of the posterior communicating artery.
