Acute digital ischemia not due to thromboembolism may be the result of either a primary vasospastic disorder (Raynaud's disease, acrocyanosis, livedo reticularis) or vasospasm associated with a systemic, regional, or traumatic disorder (Raynaud's syndrome, cold injury). Raynaud's disease versus syndrome is distinguishable up to 95% of the time from clinical criteria.
