Abstract:
The advent of duplex ultrasound (DU) has changed vascular practice over the years. Venous anatomy, valve function and obstruction can be evaluated in real time using DU. It is a low cost, portable, non-invasive, safe and operator-friendly device that can be used for diagnosis, treatment guidance and follow-up. This paper defines the patterns, location and characteristics of venous reflux and also provides insightful information on acute and chronic venous obstruction.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
