73-year-old woman with HTN, cardiac history and COVID pneumonia whose course was complicated by sepsis and duodenal ulcer perforation requiring surgical repair. She developed a cool right hand after right radial arterial line placement. Longitudinal Doppler Ultrasound image shows an elongated non-occlusive echogenic clot (arrow) with preserved peripheral flow (arrowhead) in the radial artery. The line was removed and hand ischemia improved with conservative measures.
