Welcome to the second episode of our ESVS Vascular Fundamentals podcast series. In the last episode, we looked at the relationship of pressure, flow and resistance and how they interact in the circulation. In part 2, we will be examining how these parameters are affected during exercise, intermittent claudication and limb ischaemia. We will also examine the haemodynamics of vascular grafts and aortic aneurysms. Some of the questions we will explore include why exercise is recommended for claudication, flow dynamics at the graft-arterial anastomosis and why aneurysms rupture. With Justin Woolgar and Joanna Halman.

Join us for the first of our series of Vascular Fundamentals podcasts. In our first episode, we will be breaking down the basics of arterial haemodynamics looking at the physiology of the circulation and how an understanding of it aids our decision making as vascular surgeons. We will attempt to explain the relationship between pressure, flow and peripheral resistance and how they are affected in vascular disease. What role does blood viscosity and Poiseuille's Law play in affecting blood flow? What actually is peripheral resistance? At what point does a stenosis become a significant stenosis and why? Some of the important questions we will explain. With Justin Woolgar and Joanna Halman.

In this podcast, Prof. Matthew Popplewell, lead investigator, discusses the BASIL-3 RCT, diving into the trial's design, the recruitment challenges, the statistical power, and the relevance of its findings to current clinical practice. The discussion also touches on the demographics of the patient population involved in the trial, the underrepresentation of women in vascular trials, the mortality toll of these patients, the recurrent nature of chronic limb-threatening ischemia and the implications for generalizability of the results. Unmissable!

Nationally and internationally, there is a growing awareness of radiation exposure, safety, and protection. In 2023, the ESVS issued a new guideline on radiation safety. In addition, there is growing attention to pregnant healthcare workers. This paper openly discusses the intersection of radiation safety and pregnancy. It was published as an Editor’s Choice paper in EJVES December 2024.

Here is Part 1 in our podcast series focussing on the recently published ESVS Vascular Trauma Guidelines, the first of its kind. Join us today for a personal Q&A session with the chairs of the writing committee, Professors Carl Wahlgren and Karim Brohi, themselves for an in depth look at section 2 of the guidelines: General considerations in vascular trauma. We discuss who should perform vascular trauma, what is the role of endovascular trauma, and how does the new ESVS vascular trauma classification system work, and much more.
Enjoy!

During the ESVS Annual Meeting in Kraków, we had the lovely opportunity to exchange with Flavia Gentile and Roberta Brambilla, respectively the former and current ESVS Academy Pathway Leads for Dialysis.
Together, we dig deeper into the gaps of evidence in vascular access obstruction. In this second part of this discussion.

In today's podcast, Laurence Bertrand and Suzanne Stokmans dissect this multicentre observational study from Japan recently published in the EJVES looking at infra popliteal revascularisation in CLTI. This study focuses on choosing the appropriate target lesion to achieve infrapopliteal revascularisation. They compare targeting in line flow to the wound based on personalised angiograms as opposed to in line flow to the foot based on the traditional angiosome concept.

Here is a teaser of some of what you can expect from ESVS this year... Happy 2025!

Chronic venous disease, which affects almost 70% of the population, has recently been proved to be associated with increased prevalence of cardiovascular risk factors and all-cause death. We explore the evidence sustaining this statement, potential pathophysiological pathways underlying the association, and implications for everyday clinical practice with Dr. Joana Ferreira. You'll be surprised, and inspired, by this paradigm shift!

This podcast with Prof. Robert Hinchliffe and Prof. Stephen Black gives some extra information on the EVeR registry, an initiative aimed at advancing our understanding and treatment of venous diseases. This registry is a collaborative effort between leading vascular specialists, researchers, and healthcare institutions across Europe. The registry was developed in collaboration with the European Vascular Research Collaborative (EVRC).
Deep venous diseases affect millions of people worldwide. Despite their prevalence, many aspects of these conditions remain poorly understood. EVeR will play a crucial role in addressing this knowledge gap by:
- Collecting comprehensive data: Gathering detailed information on patients with venous diseases, including their symptoms, medical history, treatments, and outcomes.
- Evaluating treatment effectiveness: Assessing the efficacy of different treatment options for venous diseases.
- Improving patient care: Ultimately, EVeR will help to improve the treatment and management of venous diseases
If you are a healthcare professional treating patients with venous diseases, we encourage you to join EVeR. By contributing data to the registry, you can help to improve the lives of patients with these conditions.
