Objective: The effects of difference in the guiding system on the results of stent thrombectomy were investigated.

Methods: Of the patients who underwent intracranial thrombectomy using a stent retriever in 2015 and 2016, those with lesions in the internal carotid artery (ICA) or the horizontal (M1) segment of the middle cerebral artery were divided into a group treated with a balloon guide catheter (BGC) alone and a group treated with a combination of BGC + distal access (aspiration) catheter (DAC), and 1) the time from puncture to recanalization, 2) number of passes, 3) frequency of occurrence of embolization to new/distal territory (ENT/EDT), and 4) percentage of complete recanalization were compared.

Results: The subjects were 17 patients consisting of 6 in the BGC group and 11 in the BGC + DAC group. The results concerning the above items were 1) 80.0 vs. 46.7 min (p = 0.03), 2) 2.8 vs. 1.5 times (p = 0.03), 3) 50% vs. 0% (p = 0.03), and 4) 66.7% vs. 90.9% (p = 0.52), respectively.

Conclusion: In the BGC + DAC group, the time until recanalization was shorter, the number of passes was fewer, and the frequency of ENT/EDT was lower, suggesting that more favorable results may be obtained by BGC + DAC.
