abstract = "Background and Purpose: In acute ischemic stroke, mechanical thrombectomy allows flow restoration in the majority of cases. In case of an unsuccessful retrieval, little is known about how many retrieval attempts should be performed before stopping the procedure. This study assessed the recanalization rate and clinical outcome per retrieval maneuver.Methods: In this analysis, 330 patients with acute large vessel occlusion treated exclusively with stentrieval devices were included. Successful recanalization was defined as Thrombolysis in Cerebral Infarction 2b-3, a good clinical outcome was defined as modified Rankin Scale at 90 days of ≤2.Results: The median number of retrieval attempts was 1 (interquartile range, 1–2, maximum 8). Recanalization rates per retrieval attempt were highest for the first retrieval (46.8%) and lowest for the fifth retrieval (22.7%). After 3 retrieval attempts, 67.9% of patients were successfully recanalized. Patients with 1 to 3 retrieval attempts had higher rates of good clinical outcome (28.9% versus 7.4%; P=0.018).

Further attempts had good recanalization rates, but the rate of favorable clinical outcome did not improve.",
