Abstract
Cancer was diagnosed in 15 patients among 300 consecutive patients with intermittent claudication. The cancer-associated claudication is characterized by a more accelerated course of claudication, more often requires vascular sur gery, and moreover, the lasting relief of claudication depends upon the effi ciency of cancer therapy. It is the authors' impression that cancer-associated claudication is predetermined by atherosclerosis and aggravated by cancer through the chronic hypercoagulability state secondary to neoplasm. The clini cal picture is characterized by rapid progression, with the frequent necessity of vascular surgery for limb salvage and a higher incidence of graft occlusion. Awareness of this possibility of hidden malignancy may be related to the clinical picture of hemodynamic deterioration of the underlying arterial insufficiency. A high index of suspicion leads to earlier diagnosis of neoplasm. Effective onco logic therapy will often bring the symptomatic relief of ischemic symptoms in the lower extremities. This report indicates that associated neoplasm has a more vicious course of the underlying arterial insufficiency and intermittent claudica tion.
