Chopstick Injury: Successful Stent-Graft Therapy for Traumatic Left Subclavian Artery Aneurysm.

Traumatic chopstick injury is very rare, especially in the vascular system. We present an unusual case of a 19-year-old man who presented at the emergency department after being stabbed with a chopstick by his elder brother. Computed tomography revealed a left subclavian artery pseudoaneurysm, which increased from 4 mm to 7 mm in diameter within 47 days. We successfully deployed a Niti-S stent graft for the increasing aneurysm, thereby avoiding a surgical operation. Balloon angioplasty was added for re-stenosis 8 months after the first intervention.
