What were the percentages of patients undergoing mechanical thrombectomy in the Anterior Cerebral Artery (ACA) and Posterior Cerebral Artery (PCA) territories in the ESCAPE (Efficient Study of Contrast Agent and Post-thrombectomy Evaluation) trial?

From the Research

Mechanical Thrombectomy in ACA and PCA Territories

• The ESCAPE (Efficient Study of Contrast Agent and Post-thrombectomy Evaluation) trial is not directly mentioned in the provided studies.
• However, study 1 discusses mechanical thrombectomy of acute distal posterior cerebral artery occlusions, which may be relevant to the PCA territory.
• Study 2 analyzes mechanical thrombectomy in anterior circulation (AC) and posterior circulation (PC) large vessel occlusions, but does not provide specific percentages for the ACA and PCA territories.
• Studies 3, 4, and 5 do not provide information on the specific percentages of patients undergoing mechanical thrombectomy in the ACA and PCA territories.

Available Data on Mechanical Thrombectomy

• Study 2 reports that out of 137 patients, occlusion was found in the M1 segment (44.5%), carotid T occlusion (37.2%), and basilar artery (18.2%).
• Study 1 includes 35 consecutive patients who underwent mechanical thrombectomy for acute distal PCA occlusion, with 25 patients (71.4%) having occlusions of the P2 segment and 10 patients (28.6%) having occlusions of the P3 segment.
• Study 5 analyzes 184 patients who underwent mechanical thrombectomy or standard medical treatment for primary distal occlusion of the posterior cerebral artery (PCA) of the P2 or P3 segment.

Limitations of Available Data

• The provided studies do not specifically report the percentages of patients undergoing mechanical thrombectomy in the ACA and PCA territories in the ESCAPE trial.
• The available data may not be directly applicable to the ESCAPE trial, and more specific information may be required to answer the question accurately 2, 1, 3, 4, 5.
