Management of neuroform stent dislodgement and misplacement

Abstract

A self-expanding stent has recently been introduced for the treatment of wide-neck aneurysms. We describe two cases of stent malposition within large aneurysms. In the first case, the stent was dislodged during microcatheterization. This was managed by placement of a second stent through the interstices of the first followed by aneurysm coiling. In the second case, after deployment, the proximal portion of the stent moved into the aneurysm as the exchange guidewire was removed. This patient was treated by vessel sacrifice.

B, Anteroposterior radiograph showing markers of the two stents: the porximal markers are in the carotid artery, the distal markers of the second stent are in the parent artery distal to the aneurysm. The first coil has been deployed and is about to be detached. C, Lateral right ICA at the completion of coiling shows filling of the center of the aneurysm. D, Aneurysm model with the end of the stent displaced into the aneurysm. E, Aneurysm model with a deployed second stent through the first stent without narrowing of either stent.
