Abstract
INTRODUCTION: Many patients seen in the emergency department (ED) have central venous access placed or previously established placement. Catheters inadvertently placed in the arterial circulation may lead to complications or adverse events. CASE REPORT: We present a case of hemiplegia in a 63-year-old man following intravenous fluid administration through a malpositioned catheter that was initially unrecognized. The patient initially presented to the ED for stroke-like symptoms and was discharged following workup. On a subsequent visit for similar symptoms, intra-arterial placement of the catheter was diagnosed. CONCLUSION: It is important for emergency physicians to be aware of this potential complication of central venous cannulation and that arterial malposition of a previously placed central line may go unrecognized with the potential to cause cerebral ischemia when cerebral blood flow is reduced by the infusion of intravenous fluids or medications.
