Prof. René Chapot is a world-renowned neurointerventionalist and a leading expert in the treatment of arteriovenous malformations (AVMs). He currently serves as the Head of the Department of Neuroradiology and Endovascular Therapy at the Alfried Krupp Krankenhaus in Essen, Germany.
Trained in Paris, Prof. Chapot began his medical career at the prestigious Hôpitaux de Paris, specializing in radiology and later focusing on interventional neuroradiology at Lariboisière Hospital. From 2003 to 2006, he held a professorship in Neuroradiology at the University of Limoges, France, before assuming his current position in Essen in 2007.
Prof. Chapot has pioneered numerous groundbreaking techniques in neurointervention. These include early adoption of aspiration thrombectomy for stroke, the venous remodeling balloon technique for dural fistulae, the “Pressure Cooker Technique” and transvenous approaches for AVMs, as well as advanced stenting and coiling strategies for aneurysms. His innovative work has had a major impact on the evolution of minimally invasive therapies for cerebrovascular disease.
A prolific researcher, physician and educator, Prof. Chapot has authored over 270 scientific publications, holds several patents in endovascular device design, and is a highly sought-after speaker and faculty member at leading neurointerventional conferences worldwide.

4D Angios for understanding brain arteriovenous malformations (ONLINE)

Arteriovenous malformations (AVMs) present one of the most complex challenges in neurovascular treatment, requiring a deep understanding of both vascular anatomy and dynamic flow patterns. In recent years, Prof. René Chapot has pioneered a paradigm shift in AVM management through the development and refinement of transvenous embolization, a technique that relies on detailed hemodynamic insight and precise imaging.
This talk will provide a comprehensive overview of state-of-the-art AVM imaging in the angiography suite, focusing on the practical application of 4D angiographic techniques and fusion imaging of hyperselective series. These tools are critical for visualizing the AVM nidus, identifying optimal access routes, and evaluating flow direction and pressure gradients—key factors that determine the success of transvenous approaches.
Drawing on years of clinical experience and innovation, Prof. Chapot will present an introduction to the imaging techniques, share practical tips, procedural pearls, and common pitfalls, and discuss their role in transforming AVM therapy. The session is essential for neurointerventionists aiming to expand their capabilities in complex AVM treatment and to better understand the dynamic physiology behind these challenging lesions.
