Background
Acute limb ischemia is often seen in the setting of embolic or chronic peripheral arterial disease. Though not as common, acute limb ischemia may also occur due to diffuse arterial limb ischemia, commonly in the setting of drug abuse. As the condition is often not diagnosed correctly, devastating complications can occur, including limb amputation. We aim to increase awareness of this condition and to describe a novel interventional strategy utilizing intra-arterial vasodilator infusion.

Educational Goals / Teaching Points
This exhibit aims to provide a brief overview of the pathology and imaging of diffuse arterial vasospasm resulting in acute limb ischemia; discuss and showcase a novel and efficacious interventional treatment strategy for acute limb ischemia secondary to vasospasm utilizing intra-arterial infusion of vasodilator medications; and provide a case-based format to illustrate the above.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes a brief overview of patient presentation and imaging of acute diffuse vasospastic limb ischemia and review of novel intra-arterial technique to treat diffuse vasospastic arterial limb ischemia (technical overview of intra-arterial vasodilator infusion and pictorial overview of patient outcomes).

Conclusion
Acute limb ischemia secondary to diffuse vasospasm may be challenge to diagnose clinically and can have devastating complications, often in younger patients. Proper identification can guide effective treatment. Intra-arterial vasodilator infusion is a novel technique for management of this underrecognized and potentially reversible condition.
