While it mimics atherosclerosis, it should be suspected in young patients without traditional risk factors who present with sudden claudication or dynamic, exercise-dependent flow inhibition. Surgical management via 360-degree resection and venous interposition currently provides the most reliable long-term results and protection against local recurrence.
