Rationale
The stale [@esvs2019-aaa] citation in the Guidelines bullet was replaced with [@esvs2024-editors], which is the directly superseding 2024 ESVS guideline covering the same recommendation for duplex ultrasound as first-line imaging in AAA surveillance. No other content changes were required as the new guideline supports the same claim without introducing materially different information for this section.

Content Changes
- Principle: Combines B-mode imaging with Doppler waveform analysis to provide both anatomic and hemodynamic information.
- Applications:
- Carotid artery stenosis grading (using NASCET and ESVS criteria); see 7Ch. 7 for complete grading tables and management thresholds.
- peripheral arterial disease (PAD) severity assessment and lesion localization (Gornik 2024).
- abdominal aortic aneurysm (AAA) diameter measurement and surveillance; see 4Ch. 4 for screening/surveillance protocols (Isselbacher 2022).
- Venous disease: reflux assessment (valve incompetence) and deep vein thrombosis (DVT) detection.
- Post-intervention graft surveillance (e.g., after bypass surgery or endovascular aneurysm repair (EVAR)).
- Advantages: Portable, non-invasive, relatively inexpensive, and repeatable without radiation or nephrotoxic contrast.
- Limitations: Operator-dependent technique with reduced accuracy in obesity, presence of bowel gas, or extensive vascular calcification.
- Guidelines: Recommended as first-line imaging for carotid disease, venous disease, AAA surveillance, and PAD diagnosis (Moneta 2010)📄 (Grant 2003) (Naylor 2018)📄 (ESVS 2024) (Wittens 2015)📄 (Almasri 2018)📄 (Aburahma 2019)📄 (Isselbacher 2022) (Gornik 2024).

Reviewer Notes
Approved after replacement-first stale-guideline regeneration review. Clean same-family replacement of stale guideline citation with the known 2024 ESVS AAA superseding guideline.
