Radiation exposure and fluoroscopy time in mechanical thrombectomy of anterior circulation ischemic stroke depending on the interventionalist's experience-a retrospective single center experience.

• There is a significant influence of interventionalist's experience on procedure time, fluoroscopy time, and radiation exposure in mechanical thrombectomy in the anterior circulation. • Interventionalists' learning curve is steepest during the first 25 cases. • These circumstances should be considered when reference levels or guide values are established and in training of physicians performing mechanical thrombectomy to promote optimization of patient doses in the future.
