Rationale
The stale [@esvs2019-aaa] citation was replaced with the superseding ESVS 2024 AAA guidelines [@esvs2024-editors] for the same claim regarding CTA technical standards supporting planning and surveillance protocols. No other content changes were warranted as the new guideline covers the same recommendation domain. The ESVS abbreviation was expanded on first use in the closing sentence per abbreviation rules.

Computed tomography angiography (CTA) Technical Parameters for Aorta and Peripheral Arteries
Optimal CTA imaging requires attention to specific technical parameters that vary by anatomic region:
Aortic and endovascular aneurysm repair (EVAR) imaging: High-quality aortic CTA employs submillimeter collimation (≤1 mm) with multiphasic acquisitions including non-contrast, arterial phase (using bolus tracking), and delayed phase for endoleak detection. ECG-gating is applied for thoracic aorta imaging when assessing the aortic root or ascending aorta to minimize motion artifact (Isselbacher 2022). Standardized contrast delivery protocols (4–6 mL/s with bolus tracking) ensure consistent arterial enhancement.
Lower extremity CTA: Imaging parameters including table speed and reconstruction kernels are optimized for distal runoff vessel assessment in patients with lower extremity peripheral artery disease (PAD), ensuring adequate visualization of tibial and pedal arteries (Gornik 2024).
These technical standards support the planning and surveillance protocols outlined in the European Society for Vascular Surgery (ESVS) 2024 Clinical Practice Guidelines on the Management of Abdominal Aorto-Iliac Artery Aneurysms and recent multisociety recommendations for aortic and peripheral vascular disease.
