Audible Bleeding contributor and vascular surgery fellow Richa Kalsi (@KalsiMD) is joined by vascular fellow Eva Urrechaga (@urrechisme),  fourth year medical student Leona Dogbe (@ldogbe4), JVS Editor-in-Chief, Dr. Thomas Forbes (@TL_Forbes), and JVS-VS editor Dr. John Curci (@CurciAAA) to discuss two great articles in the JVS family of journals. The first article analyzes amputation trends over 12 years in Oklahoma, and identifies risk factors that can be used to target intervention strategies. The second article explores the role of toll-like receptor 4 in skeletal muscle damage caused by chronic limb-threatening ischemia.  This episode hosts Dr. Kelly Kempe (@KellyKempe) and Dr. Ali Navi (@VascularChap), authors of these two papers.

Articles:

Part 1: “Analysis of Oklahoma amputation trends and identification of risk factors to target areas for limb preservation interventions” by Drs. Kempe, Nelson, and colleagues.

Part 2: “Role of toll-like receptor 4 in skeletal muscle damage in chronic limb-threatening ischemia” by Drs. Navi, Tsui, and colleagues.

Underlying disease featured in episode - peripheral arterial disease

1. Pathophysiology/etiology
   1. narrowing of peripheral arteries caused by atherosclerotic plaques causing arterial insufficiency distal to the point of occlusion. This reduces oxygen supply to the muscles.
   2. When oxygen demand increases but cannot be met, it leads to an imbalance such as pain and poor wound healing. 
   3. Risks: smoking, diabetes, hypertension, dyslipidemia, and older age
   4. Equal prevalence in men and women, peak incidence age 60-80
   5. Coexists with CAD, DM, stroke, Afib, and renal disease
2. Patient Presentation
   1. 20-50% asymptomatic, rest can be intermittent claudication, rest pain, or tissue loss
   2. claudication=pain or discomfort felt in the legs due to a lack of blood flow, especially during physical activity. 
   3. CLTI=chronic limb threatening ischemia: rest pain lasting greater than 2 weeks or nonhealing ulcers and gangrene
   4. Physical exam: 
      1. decreased skin temperature, less hair on the legs, brittle nails, atrophied muscles, shiny skin, livedo reticularis.
      2. Absent or diminished pulses
      3. Buerger sign
3. Diagnosis
   1. Ankle brachial index:

In this episode Abena Appah-Sampong (@abenasamp) and Leana Dogbe (@leanadogbe) partner with Vaiva Dabravolskaite ([email protected]) from ESVS to host an episode discussing social deprivation in vascular surgery. Dr. Tara Mastracci and Dr. Olamide Alabi join us to offer insights into how social deprivation drives disparities in outcomes and steps to how we can shift practice paradigms to better address our patient needs.

Dr. Tara Mastracci (@aorticsurgeon) is a vascular surgeon with over 15 years of experience treating and managing complex aortic pathologies. She is currently working at St. Bartholomew’s Hospital in London, UK, on the Cardiothoracic Team doing complex aortic surgery. On top of her clinical duties, Dr. Mastracci is dedicated to studying the social and non-clinical factors influencing vascular outcomes. 

Dr. Olamide Alabi (@OAlabiMD) is an Associate Professor of Surgery in the Department of Surgery at Emory University School of Medicine. Her clinical effort focuses on the full scope of vascular disease for patients at Emory University Hospital and the Atlanta VA HealthCare System, however, her academic portfolio and funded research is focused primarily on the intersection of peripheral artery disease, quality, and health equity.
