The publication of CREST-2 has reignited one of the longest-standing debates in vascular medicine: should asymptomatic carotid stenosis still be treated invasively in the era of modern best medical therapy? In this episode, Laurence Bertrand and Rosalinda D'Amico discuss the trial with Barbara Rantner and Caitlin Hicks, exploring its methodology, controversial findings, and the implications for the management of asymptomatic carotid stenosis.
Full name of guests:
Dr. Barbara Rantner – TUM University Hospital, Munich, Chair of ESVS and DGG guideline writing committee
Dr. Caitlin Hicks, Johns Hopkins University School of Medicine, Member of the writing committee ESVS and SVS guidelines

How should we approach intervention thresholds, repair strategies, and lifelong surveillance in patients with genetic aortopathies? Prof. Sherene Shalhub (Oregon Health & Science University) and Prof. Rana Afifi (McGovern Medical School at UTHealth Houston) discuss the practical challenges, controversies, and unanswered questions that shape decision-making in the management of these complex patients.

Recorded live at the ESVS Vascular Graft and Endograft Infection Workshop in Groningen, this episode explores one of the most challenging complications in vascular surgery. We spoke with Prof. Ben Saleem, Prof. Xavier Berard, and workshop participants about diagnosis, treatment strategies, difficult clinical decisions, and the key lessons learned from this unique hands-on course. A practical discussion on managing vascular graft infections, featuring expert insights and real-world experience from across Europe.

In this podcast, we are joined by Dr Alex Crichton, researcher at the Trisha Roy Vascular laboratory at Houston Methodist Hospital, Texas, to discuss how QISS MRA can be used to image tibial vessels that are often missed by more conventional forms of imaging such as CT angiography, ultrasound duplex imaging or digital subtraction angiography. Diabetic patients can be especially challenging in selecting target vessels for treatment because of the presence of calcium in the vessel wall and the distal nature of the disease. Furthermore, many of these patients have impaired renal function where the use of contrast media can be detrimental. In this episode, Dr Crichton explains the work being done with QISS MRA to enable visualisation of these so called “hibernating vessels” and also how it can be used to characterise plaque morphology and the suitability for endovascular intervention.

Rosalinda D’Amico interviews Prof. Kevin Mani on one of the key controversies in EVAR follow-up: is aneurysm sac shrinkage truly a marker of success, or can it sometimes provide false reassurance? They discuss the current definition of sac regression, the importance of timing and sac stability and whether sac shrinkage should influence surveillance strategies. The episode also explores the role of CTA versus duplex ultrasound and the future potential of volumetric and AI-based assessment in EVAR surveillance
