Vasculitic Lesion: A lesion associated with an inflammatory condition of the
blood vessels that is characteristic of certain systemic diseases or that is caused by an
allergic reaction.
Venous Eczema: Eczema associated with the development of venous ulcers. Also known
as venous or stasis dermatitis.
Venous Hypertension: Back pressure on the venous system exerted either from central
or pulmonary sources, or from extrinsic compression syndrome. Example, a mass, tumour
or tight girdle.
Venous Insufficiency: An obstruction which blocks outflow, valvular incompetence,
which permits retrograde flow, or muscle pump failure, resulting in incomplete emptying of
the venous system in the lower leg.

Venous Leg Ulcers: Wounds that usually occur on the lower leg in people with venous
insufficiency disease. Venous Leg Ulcers are also known by such terms as venous stasis ulcer
and venous insufficiency. Ulcers result from chronic venous hypertension caused by the
failure of the calf muscle pump (Blair, Wright, Backhouse, Riddle & McCollum, 1988).
Venous Ulcer: Partial to full thickness ulceration of the lower leg precipitated by venous
hypertension and venous insufficiency.
Vessicles: Elevated, circumscribed, superficial fluid filled blister less than 1 cm in diameter.
