BackgroundEmbolization of thrombus fragments in new or downstream vascular territories is a potential adverse event in neurothrombectomy, requiring additional repeated thrombectomy attempts. This study aims to describe technical results of the thrombectomy with clamping embolus technique (TCET) method in acute ischemic stroke. This study also aims to evaluate the efficiency of mechanical thrombectomy by TCET, and to compare it with conventional stent retriever thrombectomy (CSRT).Materials And MethodsA retrospective analysis was performed in 52 consecutive patients treated between January 2015 and October 2016 for intracranial large vessel occlusion by stent retriever thrombectomy. Recanalization rates, procedure durations, and thrombectomy attempts were compared between the TCET and the CSRT groups.ResultsSuccessful recanalization (thrombolysis in cerebral infarction [TICI] 2b or 3) with TCET was achieved in 91.7% (22 of 24) versus 92.9% (26 of 28) in the CSRT group (P = .921). To preserve the restored patency of severely affected atherosclerotic intracranial vessels, 7 and 8 patients received angioplasty or stenting in the TCET and CSRT groups, respectively. In embolic cases, the number of thrombectomy attempts with TCET was significantly lower than that obtained with CSRT (1.7 ± .2 versus 2.6 ± .5, respectively; P = .001); the one-pass thrombectomy rate was significantly higher in the TCET group than in the CSRT-treated patients (58.8% versus 25.0%, respectively; P = .014). Procedure duration was significantly shorter by TCET than by CSRT (35.8 ± 5.8 minutes versus 55.5 ± 7.2 minutes, respectively; P = .001).ConclusionsThe efficiency of mechanical thrombectomy by TCET in acute ischemic stroke might be improved compared with CSRT.Copyright © 2018 National Stroke Association.
