Abstract

OBJECTIVES: This study aimed to prove the safety and efficacy of the contact aspiration using non-penetrating of thrombus (CANP) technique for the initial procedure for acute ischemic stroke and to increase operator familiarization with the technical aspects of the CANP technique.

MATERIALS AND METHODS: A total of 103 patients with large-vessel stroke who were treated using thrombectomy alone at our institution between April 2019 and March 2021 were included in this study. CANP technique was performed using a large lumen catheter (inner diameter, ≥0.060 in.) without penetrating a thrombus. Results of the CANP technique, including the procedure time; first-pass effect (FPE); angiographical recanalization; functional independence; thrombus migration; and intracerebral hemorrhage (ICH) were compared with combined technique.

RESULTS: A total of 77 patients (74.8%) were scheduled to undergo the CANP technique for initial procedure, and 50 (64.9%) attempted the CANP technique. Of 50 patients with CANP technique, 33 (66.0%) achieved angiographically good recanalization using CANP technique alone. FPE was achieved in 31 patients (62.0%) in CANP technique group; the rate of FPE was significantly higher (p = 0.008). Asymptomatic ICH were significantly smaller in the CANP technique group (p = 0.008). The median interval of only the CANP technique was 20 (IQR, 16-29.5) min for groin puncture to final recanalization, and was significantly faster (p < 0.001).

CONCLUSIONS: CANP technique was safe with low risk of hemorrhagic complication and effective for the initial procedure of acute ischemic stroke.
