1. spontaneous peripheral venous thrombosis, suggestive of visceral carcinoma, especially carcinoma of the lung or gastrointestinal tract. 2. a sign for tetany in which carpal spasm can be elicited by compressing the upper arm and causing ischemia to the nerves distally. Trousseau's sign. From Polaski and Tatro, 2000. See illustration.
