  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). Post-hoc comparison: RAA: CT-A vs. other: p = 0.05, CT-A vs. no CT: p = 0.04, other CT vs no CT: p = 1.00; Chitwood clamp: CT-A vs. other: p = 0.82, CT-A vs. no CT: p < 0.01, other CT vs no CT: p = 0.03; intra-aortic balloon: CT-A vs. other: p = 1.00, CT-A vs. no CT: p < 0.01, other CT vs no CT: p < 0.01
