Rationale
The stale Wanhainen A, et al citation in the Guidelines bullet was replaced with ESVS, 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.

* **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 [[Cerebrovascular Disease|Ch. 7]] for complete grading tables and management thresholds. * peripheral arterial disease (PAD) severity assessment and lesion localization [@svs2024-gornik]. * abdominal aortic aneurysm (AAA) diameter measurement and surveillance; see [[Aneurysmal Diseases|Ch. 4]] for screening/surveillance protocols [@aha2022]. * 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 [@moneta2010] [@sru2003] [@esvs2018-esvs] [@esvs2019-aaa][@esvs2024-editors] [@esvs2015] [@almasri2018] [@evar2019] [@aha2022] [@svs2024-gornik].
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.
