ICA luminal restoration was achieved in all cases. An average of 2 FDS were deployed telescopically to cover the dissection. Balloon angioplasty was performed in two cases to improve opening of the implant. Adjunctive carotid stents were deployed in all cases to secure the proximal end of the FDS. LVOs were addressed after ICA reconstructions by combined technique and ingestion of the stentriever in the aspiration catheter, that was advanced within the construct and positioned distally to it without issue in all cases (TICI scores: 2b-3). All patients received intra-operative eptifibatide, bridged subsequently to dual antiplatelet therapy (aspirin + ticagrelor). Acute, non-occlusive in-stent thrombus was noted in 2 cases, while wire access was lost in one case, significantly increasing operative time. Hemorrhagic transformation of an acute infarct was seen in 2 (33%) patients. A good outcome (mRS 0-2 at 90 days) was achieved in 5 (83%) patients, while one died of malignant brain edema shortly after intervention. Imaging follow-up was available for 4/5 surviving patients (80%, median: 18 months) and showed complete stent patency. Conclusions FDS appear to be a safe and effective tool for reconstruction of a symptomatic dissection in tortuous cervical ICAs. Their flexibility allows conformation to complex anatomies and they can be traversed multiple times by aspiration catheters/stentrievers. We found excellent patency at follow up. The unique challenges posed by utilization of high-profile stents in acute stroke require appropriate technical execution and medical management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
