    We read the article by Kim et al with immense interest.1 The authors provide a compelling retrospective matched-pair analysis of 110 thrombectomy cases with a 1:1 ratio of patients with ischemic stroke who were managed using either balloon-guided catheters (BGC) or non-BGCs. To evaluate short- and long-term patient outcomes associated with BGC use, the investigators used relevant and thoughtful matching parameters including proceduralists, age, sex, stent retriever+aspiration device versus aspiration-only, and site of occlusion to control for confounding variables. The results suggest that BGC use potentially offers some notable advantages over non-BGC use, including higher likelihood of modified Rankin Scale score ≤2 at discharge and a significantly higher first-pass effect in aspiration-only cases (100% vs 50%, P=0.01).

    We wish to congratulate the authors on their …
