Middle cerebral artery aneurysm surgery after stent misplacement: A case report

Abstract

<jats:p> Stent misplacement during endovascular treatment of middle cerebral artery (MCA) aneurysms can cause challenges and be problematic, if clipping becomes necessary. This article reports on a 56-year-old woman with an unruptured, multi-lobulated MCA aneurysm, whom primarily refused surgery; therefore, she was scheduled for stent-assisted coiling. After successful deployment of the stent, it unfortunately then became snagged by the microcatheter and was pulled backwards. The subsequent surgical procedure (i.e. clipping of the MCA aneurysm) was challenging, due to the position of the dislodged stent. Such as misplacement of the stent is rarely documented: It resulted in the difficult handling of a MCA aneurysm. Aneurysms of the MCA should primarily be considered for surgical clipping. In conclusion, an increased risk for eventual surgery should be considered, in cases where endovascular treatments with stents are performed. </jats:p>

“…The vascularization in SF can be highly complex because of which the dissection may be difficult [2, 14-16]. The MCABAs are explained according to the dome projection with different positions in this study.…”

“…Third, its local drug delivery capability would minimize the possible systematic side effects. Finally, its position could be adjusted actively if misplacement or dislodgement 48 during the endovascular operations or migrations after the surgeries occurs 49 – 51 , e.g., as flow diverters to treat wide-neck aneurysms. For the detailed point-to-point experimental justifications of these advantages, please refer to Supplementary Note 5 .…”
