Objectives:
Understand the potential consequences of deep vein thrombosis (DVT) in patients undergoing superficial venous interventions, the proper way to assess DVT risk in patients with superficial venous disease and the appropriate management of patients stratified by risk level.
Methods:
Review of published literature
Results:
Because DVT can have major long-term consequences, DVT risk should be assessed as a routine part of the preprocedure evaluation of venous disease. Chronic venous disease may have multiple contributing factors amenable to treatment in both the superficial and deep venous systems.
Conclusion:
Superficial venous interventions should be deferred in patients at particularly high risk for DVT, but may be performed with appropriate countermeasures for DVT prophylaxis in patients at moderate risk.

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...
