  1. Patients with preoperative CT angiography (CT-A, n = 63) compared to patients with non-contrast CT (other CT, n = 35) and patients without preoperative CT scan (no CT, n = 45). Only CT-A was able to offer all the displayed information
  2. LAA left axillary artery, LFA left femoral artery, RAA right axillary artery, RFA right femoral artery
