Beschreibung

A comprehensive, quick-reference guide to the diagnosis and management of peripheral artery disease for non-specialists

With an aging population subject to an increasing number of health risks, peripheral artery disease (PAD) is on the rise throughout the world. Because of PAD's direct links to heart attack and stroke, it is critical that internists, surgeons, cardiologists, radiologists, gerontologists, GPs, and family practitioners know how to recognize it and make the best treatment recommendations for their patients. This book provides all the expert, practical information and guidance they need to do just that. 

Edited by two thought leaders in PAD diagnosis and treatment, and comprising chapters written by subject matter experts, Peripheral Artery Disease, Second Edition provides clinicians with guidance on how to diagnose and treat one of the most under-diagnosed conditions affecting millions of patients. This updated and revised edition of the popular guide distills the complexities of PAD into clear, actionable advice for busy medical practitioners, providing them with the information they need—when they need it.

  • Provides clinicians with essential information for recognizing and treating this under-diagnosed condition that affects millions of patients
  • Distills the complexities of PAD, from diagnosis to traditional and emerging treatment options, into clear, actionable advice for clinicians
  • Covers PAD epidemiology, office examination, imaging, laboratory evaluation, medical therapy, surgical interventions, endovascular treatments, and much more
  • Reflects the latest PAD Guidelines and Performance Measures established by leading specialty societies
  • Features contributions from internists and surgeons, all recognized experts in PAD

Peripheral Artery Disease, Second Edition is an important working reference for internists, cardiologists, radiologists, and surgeons, as well as fellows and residents in those fields.

Chapter 3: Vascular Laboratory Evaluation of Peripheral Artery Disease

Figure 3.1 (a) Normal Doppler signal showing triphasic flow. (b) Monophasic Doppler signal obtained distal to a hemodynamically significant arterial lesion. The wave is dampened and delayed. Note the absence of forward flow in late diastole.

Figure 3.2 A series of pulse-volume recording cuffs placed at multiple levels of the limb(s).

Figure 3.3 (a) Normal pulse-volume recording (PVR) waveform. The “notch” in the down-slope (dicrotic notch) results from the reflected pulse wave during diastole. (b) PVR obtained distal to a hemodynamically significant arterial lesion. The amplitude is reduced and the contour has changed.

Figure 3.4 The ankle–brachial pressure index (ABI) for a limb is obtained by dividing the ankle pressure (using the higher of the dorsalis pedis or posterior tibial pressure) by the arm pressure (the higher obtained from either arm).

Figure 3.5 Exercise study in patient with left lower limb peripheral artery disease (PAD). In normal limbs (right), both the arm and leg pressure rise with exercise. In limbs with PAD (left) the arm pressure rises but the ankle pressure falls. The exercise capacity, post-exercise pressure fall, and pressure recovery time reflect the severity of the PAD.

Figure 3.6 Transcutaneous oximetry electrodes are placed over points of interest and sealed to the skin with air-tight tape.

The profunda femoris branches are incompletely filled due to the timing of the image. (b) Unsubtracted angiogram of the same study shows the adjacent bone. (c) Carbon dioxide DSA of the right hip shows severe stenosis of the origin of the right superficial femoral artery (arrow), along with multifocal stenosis of the superficial femoral artery (curved arrow). There are also several areas of stenosis in the profunda femoris artery and its branches. (d) DSA of the distal thigh and knee shows motion artifact limiting (arrow) vascular evaluation.

Figure 4.4 Intravascular ultrasonography (IVUS) of the lower extremity. (a) Normal IVUS image of the superficial femoral artery showing a normal echogenic intima (arrow) and hypoechoic media (arrowhead). (b) IVUS image shows eccentric intimal plaque (arrowheads) in the superficial femoral artery.

Preface

Peripheral artery disease (PAD) is unfortunately infrequently recognized. The treatment of PAD continues to evolve but is fundamentally focused on control of risk factors in order to prevent the associated risk of heart attack, stroke, and premature cardiovascular death as well as improvement in exercise performance and limb preservation. The pathophysiology of progressive atherosclerotic plaque in the extremities is thought to involve plaque hemorrhage and rupture, but few data support this presumption. Clinical research is needed to develop agents designed to halt progression of atherosclerotic disease in the peripheral arterial system. Despite these current limitations in understanding and treating PAD, new lipid modifying agents and new antiplatelet treatment of risk factors and strategies to improve pain-free walking distance have emerged, including the use of emerging endovascular strategies. In addition, with the rapid evolution of technology to improve arterial perfusion with minimally invasive catheter-based strategies, options for revascularization of patients with advanced symptoms and signs of PAD are improving.

The primary objective of Peripheral Artery Disease is to provide the reader with the most current information on diagnosis and treatment of PAD.

We hope that this reference provides an easy-to-use resource for the practicing clinician, ultimately resulting in better care for our patients. In addition, we would like to dedicate this entire book to Alan T. Hirsch, MD, who died suddenly and unexpectedly in April 2017. It minimizes his impact on the field and all vascular specialists to discuss his publications, presentations, and advocacy. Alan was a tireless voice for patients around the World who suffered from PAD. It was through his efforts that exercise and guidelines-based medical therapies have become primary in the management of these patients. We will forever miss his enthusiasm, humor, expertise and care, but most importantly, the World is a bit smaller with his passing.
