In the matching process, situations arose where an already matched PA treated AcomA was selected as the most similar in additional cases. Among the seven unruptured cases (highlighted in blue), one pterional approached AcomA exhibited the closest similarity to two different interhemispheric approached AcomA. Similarly, among the seven ruptured cases (highlighted in yellow), two cases involved pterional approached AcomA identified as the most similar to two different interhemispheric approached AcomA. To resolve these cases, the second and third matches were evaluated by two independent neurosurgeons to determine the final match. No disagreements occurred between the investigators during this process
