The episode discusses the evolving approach to treating asymptomatic carotid artery stenosis in light of modern medical therapies and recent trial data.

For decades, a tight carotid stenosis felt like a ticking time bomb — a plaque waiting to throw an embolus and cause the next stroke. We were taught that severe narrowing meant surgery, and trials like ACAS and ACST-1 seemed to prove it. But medicine has changed. Statins, antiplatelets, tighter blood pressure control, even PCSK9 and GLP-1 therapies have quietly slashed stroke risk, and now newer data from CREST-2 suggest that for many asymptomatic patients, the knife — or the stent — may not add much at all. So if modern medical therapy works better than ever… who actually benefits from intervention anymore? Today, we unpack the evidence, the controversies, and how to counsel the patient who feels perfectly fine but has high-grade stenosis. Hosts: Carolyn Judge, Andrew Huang, Luciano Delbono, Frank Davis, Robert Beaulieu Institution: University of Michigan, Department of Surgery, Section of Vascular Surgery Learning objectives: Describe how modern intensive medical therapy has transformed the natural history of asymptomatic carotid stenosis and explain why contemporary patients experience substantially lower annual stroke risk than those in earlier eras. Interpret and compare the…
