title: Varicose ulcer of the upper extremity.
abstract: Serious complications of local venous hypertension occur rarely in the upper extremity. These are most frequently the result of a dysfunctional arteriovenous fistula and may produce changes indistinguishable from those of chronic lower-extremity venous insufficiency. A combination of arterial and venous contrast imaging is essential for identifying major venous outflow obstruction and for planning appropriate surgical therapy.
