Superficial venous interventions: assessing the risk of DVT.
OBJECTIVE
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.


CONCLUSIONS
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.
