Introduction
Ultrasound examinations to exclude the presence of lower limb deep venous thrombosis (DVT) are very commonly performed procedures. Many patients present for postoperative screening or for unilateral painless leg swelling, and these are quite appropriate clinical symptoms suggestive of DVT. There is also a subgroup of patients, who present with a clinical history suggestive of alternative pathology, in particular, a history of medial calf pain. In these patients I would advocate a five-minute extension of the standard DVT exclusion examination to assess the possible presence of a variety of alternative pathologies.
