Inclusion Criteria

CT imaging with contrast agent and at least one arterial phase
• Presence of thrombotic occlusion or arterial hemorrhage (evidenced by CT imaging)
• DSA was performed following CT imaging
• In case of arterial bleeding detected on CT, evidence of spontaneous hemostasis on DSA (i.e. no more bleeding on DSA)
