Introduction The upper extremity arterial system requires a different diagnostic approach than that used in the lower extremity. Although progression of focal atherosclerosis or acute arterial emboli are almost always…
Overview The current trends in vascular imaging are to increase the reliance on noninvasive approaches, to minimize complications linked to invasive imaging, and to reserve invasive techniques for therapeutic interventions….
Introduction Vascular emergencies require a prompt diagnosis, as timely intervention is often critically important. Delays of minutes or hours in diagnosis may mean the difference between life and death, or…
Introduction Noninvasive testing for lower extremity arterial disease provides objective information that can be combined with the clinical history and physical examination to serve as the basis for decisions regarding…
Introduction In this chapter, we will review the normal anatomy and sonographic appearances of the abdominal arteries and veins. We will include an analysis of the normal Doppler waveforms of…
Introduction Endovascular aneurysm repair (EVAR) uses endografts, also called endovascular grafts, covered stent-grafts, or transluminally placed endovascular grafts to isolate an aortic aneurysm from the circulation. EVAR is preferred to…
Introduction Venous thromboembolism is a major health problem, especially among the hospitalized, the elderly, and the patient with underlying hypercoagulable states such as cancer. Deep vein thrombosis (DVT), defined as…
Introduction This chapter serves as an introduction to the physical and technical aspects of vascular sonography, including the following: (1) ultrasound principles, (2) transducers, (3) instruments, (4) advanced features, and…
Introduction Carotid occlusion is one of the most important diagnoses that is made in the vascular laboratory or imaging department. The distinction between carotid occlusion and near-total occlusion or high-grade…
Introduction The identification of carotid artery stenosis is the most common indication for cerebrovascular ultrasound. The majority of stenotic lesions occur in the proximal internal carotid artery (ICA); however, other…
