Abstract:
Anatomical variations in the superficial and deep palmar arches are common, but rarely lead to digital necrosis. We report the case of necrosis of the third digit caused by a 'watershed' effect in the context of atherosclerotic disease and rare congenital variations of the superficial and deep palmar arches.
