What is Inverted stent deployment technique for stent assisted coiling of wide-necked posterior communicating artery aneurysm: Technical report about?

## Background: Wide-necked aneurysms of the posterior communicating artery associated with a fetal posterior cerebral artery that arises from the neck or dome of the aneurysm is a clinical scenario that poses a challenge to endovascular methods. ## Case description: A patient presented with spontaneous subarachnoid hemorrhage and was found to have a 4 × 3 × 3 mm posterior communicating artery aneurysm. of note the aneurysm projected superiorly and a fetal posterior communicating artery aneurysm arose from the neck of the aneurysm. after multidisciplinary discussion a treatment strategy of endovascular stent-assisted coiling was chosen. given the unique morphology of the aneurysm a novel stent-inversion maneuver was used, in which the stent was deployed from the posterior communicating artery into the distal supra-clinoid internal carotid artery. the patient tolerated the procedure well and complete aneurysm occlusion was achieved. ## Conclusions: This case demonstrates a novel stent inversion technique that can be used for stent-assisted coiling of certain challenging aneurysms.
