The deployment of balloon-mounted stents presents an expedient approach with renewed feasibility in the modern era of supple intermediate catheters.Methods A prospectively maintained endovascular stroke database was searched for patients undergoing intracranial stenting with balloon-mounted stents for acute LVO. Demographic, angiographic, and clinical data were extracted to determine procedural technique and success, measured both angiographically and clinically.Results Sixty patients underwent stenting for acute LVO secondary to ICAD. Mean presenting National Institutes of Health Stroke Scale (NIHSS) score was 18 and 62% of treated sites were in the posterior circulation. Cases were performed under IV conscious sedation unless the patient was already intubated. Successful recanalization was achieved in 93% of cases (Thrombolysis in Cerebral Infarction (TICI) grade 2b in 48% and TICI grade 3 in 45%). Mean improvement in NIHSS score on post-procedure day 1 was 3.4. Good outcome (modified Rankin Scale score 0–2) at 3 months was 34% and the mortality rate was 34%. The rate of peri-procedural symptomatic hemorrhage was 8% and the rate of acute/subacute stent thrombosis was 7%. In this small cohort, patient age, sex, presenting NIHSS, comorbidities, smoking, tissue plasminogen activator administration, and stent location were not significant predictors of recanalization or good outcome.Conclusion Treatment of acute LVO stroke with balloon-mounted stents for ICAD has reperfusion rates and clinical outcomes comparable to thrombectomy, with higher rates of hemorrhage and mortality. Because stent placement was performed after attempted thrombectomy, a trial of primary stenting versus thrombectomy should be considered in patients suspected of underlying ICAD. ER -
