Acute ischemic stroke resulting from tandem lesions — insights from a Thrombectomy Capable Stroke Center in Kashubia region (Poland). The frequency, causes, procedural intricacies, and complications of tandem lesions compared to isolated intracranial

In the analyzed cohort of interventionally treated AIS patients, the presence of tandem lesions was correlated with poor clinical outcomes and associated with the presence of atherosclerosis risk factors. Endovascular procedures in these cases were more complex and involved extended time intervals. Conversely, patients with isolated intracranial lesions were generally older, with atrial fibrillation being the primary risk factor. In these patients, endovascular procedure times were shorter and resulted in more favorable clinical outcomes.
