Introduction Venous structure and function are different from their arterial counterparts. Although they both transport blood, the veins perform multiple different functions. Their tasks include transporting blood back to the…
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…
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…
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 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 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 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…
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…
