Acute deep venous thrombosis (DVT) of the lower extremities is a serious an
d potentially fatal disorder which often complicates the course of severely
ill, hospitalized patients but may also affect ambulatory and otherwise he
althy people. It is uncommon in young individuals and becomes more frequent
with advancing age. The clinically important problems associated with DVT
are death from pulmonary embolism (PE), morbidity resulting from the acute
event, the post-thrombotic syndrome, and the inconvenience and side-effects
of investigations and treatment. Furthermore, an often underemphasized pro
blem is the anxiety that may occur in those patients who have suffered a th
rombotic episode.
