Tóm tắt

Evaluation of the results of mechanical thrombectomy (MT) with acute ischemic stroke (AIS) due to large vessel occlusions (LVO) at Bach Mai hospital. 227 patients with acute ischemic stroke due to large vessel occlusion were treated at Bach Mai Radiology Center from January 2018 to June 2019. Patients were divided into sub-groups depending on the treatment method. Successful recanalization rate (TICI 2b-3), good clinical recovery (mRS ≤2) after 3 months and other clinical and imaging features were analyzed and compared. The mean age was 65 ± 13 with 55% males. The NIHSS, ASPECTS and pc-ASPECTS baseline were 14.3, 7.7 and 7.6 with the distribution of occlusion sites as 23.8% ICA, 41.9% M1, 13.2% M2, 11.5% Tandem and 9.7% BA. The ratio of good revascularization (TICI 2b-3) was 84.6% after first-choice devices of 93 stent retriever (41%), 90 aspiration (40%) and 44 Solumbra (19%) – no significant difference seen (p > 0.05). 3 months after treatment, patients with good clinical recovery (mRS ≤ 2) accounted for 65.2% while intracranial symptomatic hemorrhage rate was only 3.5%. Thrombectomy for AIS patients due to LVO is very effective with high rate of good revascularization and clinical recovery. Using different mechanical devices at first pass (stent, aspiration or solumbra) do not correlated to any significantly different results.
