| Popis: | Objective To evaluate the effectiveness of micro-clamping stent-retriever thrombectomy (MSRT) in patients with acute ischemic stroke with intracranial large vessel embolism (ILVE), and compare it with that of conventional stent-retriever thrombectomy (CSRT). Methods We retrospectively evaluated 108 patients with ILVA treated by MSRT (n = 52) or CSRT (n = 56) from the 2 participating institutions between January 2016 and November 2017. The rates of successful (Modified Thrombolysis in Cerebral Infarction [mTICI] grade 2b or 3) and complete reperfusion (mTICI grade 3), time from guide catheter placement to reperfusion, rates of first-pass success, and the number of passes for reperfusion were compared between the MSRT and CSRT groups. Results The complete reperfusion (mTICI 3) rates by MSRT were significantly higher than those achieved with CSRT (78.8% [41/52] vs. 57.1% [32/56], respectively; P = 0.016). Successful reperfusion (mTICI 2b or 3) rates were 92.3% (48/52) in the MSRT group and 83.9% (47/56) in the CSRT groups (P = 0.181). The mean number of passes for reperfusion was significantly lower with MSRT compared with CSRT (1.5 ± 0.2 vs. 2.5 ± 0.5, respectively; P = 0.001). The first-pass success rates were significantly higher in the MSRT group than in the CSRT group (65.4% [34/52] vs. 28.6% [16/56]; P = 0.0001). The mean time from guide catheter placement to reperfusion was significantly shorter in the MSRT group (20.5 ± 6.6 minutes vs. 46.3 ± 7.6 minutes; P = 0.001). Conclusions These findings suggest that the complete reperfusion rates and mechanical thrombectomy efficiency in patients with ILVE are better after MSRT compared with CSRT. |
