Intentional Intra-arterial Injection of Heroin: A Case Report.

Abstract

Intravenous injection of drugs is associated with a host of medical complications, notably soft-tissue infections. On the contrary, intra-arterial injections of drugs have also been reported, largely restricted to inadvertent injections. Here we describe a patient who engaged in repeated intra-arterial injections of heroin when she exhausted most of her venous access, and presented acutely with a radial artery occlusion requiring thrombolytic therapy. Clinicians should have a high index of suspicion for intra-arterial injection in injection drug users who present with limb pain, ischemia, and motor/sensory deficits. Given the reluctance patients may have in discussing their injection practices, clinicians should proactively discuss and counsel patients about safe injection practices and the dangers of intra-arterial injections.
