Duplex Ultrasound Linked to Lower Stroke Risk After CEA

A VQI registry analysis of over 208,000 carotid endarterectomies (2012-2024) compared completion imaging modalities—none, Doppler, duplex ultrasound, and angiography. Among patients requiring intraoperative re-exploration, duplex was associated with significantly lower adjusted odds of postoperative stroke compared with no imaging, Doppler, and angiography, while angiography had the highest re-exploration and stroke rates. The study notes that despite this safety signal, duplex remains underused, with most CEAs over the past 15 years relying on Doppler or no completion imaging.

Most relevant for: Surgeons performing carotid endarterectomy and making intraoperative decisions about completion imaging technique.
