One of its most beneficial contributions to the bedside care of these patients comes from its ability to visualize vascular anatomy. As technology has become more operator-friendly and economical tissue resolution has also improved allowing vascular structures of all sizes to be clearly evaluated and interrogated in real-time. Two indications that have been studied extensively in the ultrasound-focused literature include the diagnosis of deep venous thrombosis DVT and the placement of vascular access. Once the observation of unilateral lower-extremity swelling is made confirming the diagnosis of DVT by means of invasive venogram has since been replaced by ultrasound examination.

This chapter analyzes the data surrounding these common practices and makes recommendations on how best to incorporate ultrasound into daily practice. Anatomy In order to be successful in vascular ultrasound one needs a comprehensive understanding of the venous and arterial
