False aneurysm in the palmar segment of the ulnar artery: report of a case.

A case demonstrating a false aneurysm in the palmar segment of the ulnar artery caused by a Fogarty's catheter, which had been inserted during a thrombectomy, is described. The diagnosis was suspected based on a clinical examination, and duplex ultrasonography and computed tomography (CT) confirmed an aneurysm in the palmar segment of the ulnar artery. The patient underwent a successful aneurysmectomy with end-to-end reanastomosis.
