Vascular Fundamentals - Haemodynamics of Venous Disorders - Part 4
Welcome to the final episode of our ESVS Vascular Fundamentals podcasts. In the last episode, we looked at some basic venous physiology. In this podcast, we will be looking at the haemodynamics of specific venous disorders such as acute venous thrombosis, primary varicose veins and chronic venous insufficiency. Ever wondered why exactly a DVT causes limb swelling? What happens to the venous physiology in phlegmasia? Why do people get varicose veins? What are the haemodynamic consequences of chronic venous insufficiency? Lots more burning questions that we will answer! Stay tuned!With Justin Woolgar and Joanna Halman.

Vascular Fundementals Part 3 - Venous Haemodynamics
Welcome to Part 3 of our ESVS Vascular Fundamentals series of podcasts. In the last two podcasts we concentrated on arterial haemodynamics; now it's the turn of the venous system.In this episode we look at what constitutes venous pressure and flow. How does blood flow in this low pressure system with what are effectively collapsible tubes. We explain what happens to venous pressure on standing and during exercise. What is ambulatory venous pressure? How does the cardiac cycle affect venous pressure? We will also explain how important the calf muscle pump is in reducing venous pressure and returning blood to the heart. What role do venous valves play? All basic principles in understanding venous patho-physiology.With Justin Woolgar and Joanna Halman.

Vascular Fundamentals: Arterial Haemodynamics - Part 2
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.

Vascular Fundamentals: Arterial Haemodynamics - Part 1
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.

BASIL-3 RCT with M. Popplewell, lead investigator
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!Read the full text- article open access through this link:https://www.bmj.com/content/bmj/388/bmj-2024-080881.full.pdf And check out the companion BASIL Prospective Cohort Study mentioned in the podcast:https://www.ejves.com/action/showPdf?pii=S1078-5884%2823%2900804-3
The ESVS offers resources for vascular surgeons, nurses, trainees and more so we may fulfil our mission of improving vascular health for the public benefit.ESVS has received sponsorship for the inclusion of some topics to be addressed in some podcasts, but the focus, content and development of all podcasts are fully independent.
