Purpose: Red blood cell distribution width (RDW) evaluates the variation (size heterogeneity) in red blood cells. Elevated RDW has been identified as a predictor of poor functional outcomes for acute ischemic stroke. The association between elevated RDW level and poor functional outcome in stroke patients undergoing mechanical thrombectomy has not been reported before. This study aims to investigate this relationship.Materials and Methods: This was a multicenter retrospective study involving the prospectively and consecutively collected data of 205 adult stroke patients who underwent mechanical thrombectomy for anterior circulation large vessel occlusion (middle cerebral artery M1, anterior cerebral artery A1, tandem ICA-MCA, carotid T) between July 2017 and December 2019. RDW cut off levels were accepted as >16%. The effect of elevated RDW on poor functional outcome (modified Rankin scale 3–6) was investigated using bivariate and multivariate regression analysis.Results: Elevated RDW was significantly associated with poor functional outcome in bivariate and multivariate analysis (odds ratio [OR] for RDW >16%, 2.078; 95% confidence interval [95% CI], 1.083–3.966; P=0.027 and OR for RDW >16%, 2.873; 95% CI, 1.342–6.151; P=0.007; respectively).Conclusion: These findings suggest that elevated RDW may be an independent predictor of poor functional outcomes in ischemic stroke patients undergoing mechanical thrombectomy.

Purpose: In a minority of cases, the transfemoral approach cannot be performed due to unfavorable anatomical barriers. In such cases, direct common carotid artery puncture (DCCAP) is an important alternative for rescue mechanical thrombectomy. The purpose of this study was to evaluate the efficacy and safety of DCCAP in patients with an unaccessible femoral route for mechanical thrombectomy.Materials and Methods: This is a retrospective study using data in the Turkish Interventional Neurology Database recorded between January 2015 and April 2019. Twenty-five acute stroke patients treated with DCCAP were analyzed in this study. Among 25 cases with carotid puncture, 4 cases were excluded due to an aborted thrombectomy attempt resulting from unsuccessful sheath placement.Results: Patients had a mean age of 69±12 years. The average National Institutes of Health Stroke Scale score was 16±4. Successful revascularization (modified Thrombolysis In Cerebral Infarction 2b-3) rate was 86% (18/21), and 90-day good functional outcome rate (modified Rankin Scale 0–2) was 38% (8/21).Conclusion: DCCAP is a rescue alternative for patients with unfavorable access via the transfemoral route. Timely switching to DCCAP is crucial in these cases.
