Characteristics and clinical significance of aortic ulcer signs on computed tomography angiography in patients with Takayasu's arteritis

Key Points

• To explore the characteristics and clinical significance of aortic ulcers in patients with Takayasu's arteritis.
• Analyzed computed tomography angiography (CTA) images of Takayasu's arteritis patients
• Assessed the correlation between aortic ulcers and clinical features, including Numano V
• Evaluated the role of systemic activity in relation to aortic ulcers
• Aortic ulcers were independently associated with Numano V classification
• No significant correlation was found between aortic ulcers and current systemic activity
• Indicates that aortic ulcers might reflect long-term structural changes.
