Large saccular aneurysm and A-V fistula of the brachial vessels.

This paper reports a 39-year-old patient who developed an unusually large saccular false aneurysm and A-V fistula of the brachial vessels following a neglected penetrating wound. Rapid enlargement to 15 cm appeared after one year and the aneurysm was then stable for the six months prior to operative repair. The aneurysm was excised and lateral closure of the vessels restored continuity with uneventful recovery.
