OBJECTIVE
To illustrate the importance of preoperative duplex varicose vein scan for the selection of operation and as a guide to surgery.


METHODS
Illustration of varicose patterns and anatomical details provided by duplex but difficult or impossible to obtain by other means.


CONCLUSIONS
Routine preoperative duplex evaluation is mandatory if varicose vein surgery is to be done on patients with accurate diagnosis.
