Background and PurposeExperienced multidisciplinary stroke team and well-organized hospital management are considered necessary to achieve good results after mechanical thrombectomy (MT) in acute ischemic stroke patients. We analyzed the technical results of MT performed in the Czech Republic in the year 2016 to provide relevant data for further quality improvement.Material and MethodsAll centers performing MT in the CR were called for detailed technical and clinical data from year 2016, which were anonymously analyzed and relevant technical key time intervals were compared. Clinical outcomes were assessed according to the HERMES meta-analysis.ResultsIn the 2016, 1053 MTs were performed in the CR. Of 15 dedicated centers, the data from 12 centers and from 886 (84%) patients (49.2% males, mean age 69.812.3years) were analyzed. The overall median of time from hospital arrival to groin puncture (GP) was 77min with a range from 40 to 109min among individual hospitals, from GP to first passage of stent retriever 20 (15-40) min and from GP to maximal reached recanalization 42 (33-80) min. The median of recanalization time was 240 (219-320) min. The recanalization (TICI 2b-3) was achieved in 81.7% of patients, 44.1% of patients had a good 3-month clinical outcome and 6.3% suffered from symptomatic intracerebral hemorrhage. Peri-procedural complications were recorded in 89 (10%) patients.Conclusion Despite achieved good overall results, a great variability in some of the analyzed key time intervals among individual centers performing MT warrants further quality improvement.
