Effect of cumulative case volume on procedural and clinical outcomes in endovascular thrombectomy

This is the first paper addressing the question of how the number of mechanical thrombectomies affects recanalization and outcome in the modern era of large vessel occlusion endovascular treatment. The authors processed all data from Korean cases between 2011-2015, and stratified results in several groups related within the number of cases done.

In a determined hospital, its data could fit in different groups depending on which period of their experience was done. As one could expect (but now proved) there was a direct correlation between a greater number of cases done and better recanalization rates and 3 months outcome (mRS ≤ 2). Moreover, a negative correlation with hemorrhagic complications and mortality was observed when more cases were performed.
