Point-of-care Ultrasound for the Evaluation of Acute Arterial Pathology in the Emergency Department: A Case Series

INTRODUCTION: The use of point-of care ultrasound (POCUS) in the evaluation of vascular emergencies including abdominal aortic aneurysm and deep vein thrombosis is well established. However, no current guidelines exist to outline the use of POCUS in the management of acute peripheral arterial pathology. CASE SERIES: Here, we present a case series that illustrates the utility of POCUS in the assessment of both traumatic and nontraumatic peripheral arterial disease. Direct visualization of the vasculature via B-mode, color Doppler, and pulsed-wave Doppler assisted in the diagnosis of the following: 1) an acute, post-catheterization thrombus of the proximal radial artery; 2) a complete, traumatic radial artery transection; 3) a forearm hematoma with active arterial extravasation; 4) a traumatic arteriovenous fistula; 5) an acute thrombosis of an artery bypass graft; and 6) an infected pseudoaneurysm. CONCLUSION: The incorporation of POCUS into patient care allowed for rapid identification of significant peripheral arterial pathology and led to changes in clinical management, expedited patient care, and circumvented potentially harmful complications.
