Acute ischemic stroke is common in elder patients. This study investigates whether using the balloon-guided catheter (BGC) would improve effect of stent thrombectomy (Solitaire FR With Intracranial Support Catheter for Mechanical Thrombectomy, SWIM) patients with acute due to large vessel occlusion (AIS-LVO).The data 209 AIS-LVO underwent SWIM were collected retrospectively from January 2017 June 2021. These divided into two groups based on they used BGC or not. The propensity score matching (PSM) analysis was compare differences first pass (FPE), successful recanalization, embolus escape rate, symptomatic intracranial hemorrhage (sICH), 90-day clinical favorable outcome, all-cause mortality, and complications treated combined conventional catheter.Among patients, 44 165 After matching, a total 111 included. results showed that there no statistical difference FPE (35.1% non-BGC group compared 24.3% group, matched RR, 0.59; 95% CI, 0.24-1.44), recanalization (89.2 vs. 91.9%, 1.37; 95%CI, 0.34-5.51), (6.8 8.1%, 1.22; 0.28-5.40), sICH (8.1 13.5%; 1.77; 95%CI 0.50-6.24), outcome (48.7 54.1%, 1.11; 0.51-2.46), mortality (17.6 21.6%, 1.29; 0.48-3.47), incidence 5.4%, 0.79 0.15-4.27). indicate as first-line treatment AIS-LVO, significance FPE, final distal emboli, sICH, procedural time, without BGC.Balloon-guided does not affect result AIS-LVO. Our will guide daily practice, adoption use guided balloon.
