Ultrasound Screening for Vascular Disease
Introduction Medical screening is the process of using a diagnostic algorithm to detect a disease or the susceptibility to develop a disease. A screening process can consist of a medical…
Credentialing, Accreditation, and Quality in the Vascular Laboratory
Introduction Ensuring the quality of studies performed and interpreted in the vascular laboratory is a cornerstone of vascular laboratory management. This chapter will review the processes for credentialing of personnel…
Anatomy and Normal Doppler Signatures of Abdominal Vessels
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…
Ultrasound Assessment Following Endovascular Aortic Aneurysm Repair
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…
Ultrasound in the Assessment and Management of Arterial Emergencies
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…
Ultrasound Diagnosis of Lower Extremity Venous Thrombosis
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…
Ultrasound Assessment During and After Carotid and Peripheral Interventions
Introduction Noninvasive imaging during and following carotid artery and peripheral arterial interventions can improve procedural and patient outcomes. Duplex ultrasound imaging alone or in conjunction with extremity systolic blood pressure…
Ultrasound Diagnosis of Venous Insufficiency
Introduction The term chronic venous insufficiency most often refers to venous valvular incompetence in the superficial, deep, perforating and/or the nonsaphenous veins of the lower limb. Although it is thought…
Nonvascular Findings Encountered During Venous Sonography
Introduction It is not unusual to encounter incidental findings during the course of a venous examination. Some of these findings may be the cause of extremity pain or swelling apart…
Assessment of Upper Extremity Arterial Disease
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…
