Work-Related Vascular Injuries of the Hand — Hypothenar Hammer Syndrome

Abstract

Figure 1. A 47-year-old construction worker reported a two-month history of blanching of the second to fifth fingers and a recent ulcer on the tip of the third finger of his right hand. One week before the onset of symptoms, he had straightened a slab of iron with a hammer. Angiography (Panel A) revealed an aneurysm of the distal ulnar artery measuring 5 mm in diameter (large arrowhead) and occlusions of digital branches presumed to be secondary to thromboembolism (small arrowheads). Surgery revealed a partially thrombosed false aneurysm of the ulnar artery, which was resected. The postoperative course was uneventful, . . .
