Among the varied methods of diagnosis in vascular medicine, duplex ultrasonography remains the primary modality, and continues to evolve as an accurate, reproducible, and inexpensive method to diagnose and follow patients with arterial and venous disorders. Duplex ultrasonography also remains the best diagnostic technique for extracranial carotid artery disease. Most atherosclerotic disease is limited to the origin and proximal internal carotid artery, and at this location, the vessel is commonly straight. This CD-ROM advances the field of multimedia education, presenting every aspect of carotid duplex ultrasonography in this unique format, including anatomy and physiology, the basics of ultrasound, and the performance of carotid duplex scanning. Following this, several real-life cases are presented, and the user is instructed to answer questions, such as which probe to use, what the study reveals, etc. All aspects of duplex scanning, including non-atherosclerotic carotid disorders (fibromuscular dysplasia, spontaneous dissection, etc) and carotid stent-supported angioplasty, are reviewed in-depth.
