Per article: a (b)(6) female presented to the emergency department after a traumatic fall with symptoms of an acute stroke.Iv access failed and humeral io access was obtained using the ezio device and placement confirmed (no size of needle indicated).Contrast media was injected at 3.5 ml/sec and during scan an extravasation of approximately 20 ml of contrast was noted within the gleno-humeral joint.The patient denied post procedural pain, and physical exam failed to reveal a neurological or vascular deficit, either immediately after the scan, the following day or one-week post-procedure.The exact cause of the extravasation was unknown with possible causes being 1) the humeral io needle can pass through the subdeltoid bursa during placement.Contrast passing retrograde along the ion tract could then enter the joint space via its connection to the bursa 2) a change in orientation of the driver during placement may have widened the needle tract 3) contrast passed directly into the joint space through an interruption in the periarticular bone.
