Abstract
A high origin of the radial artery (brachio-radial artery; BRA) is the most common variation in the upper extremity. However, the clinical significance of this variation is rarely recognized in daily practice. We experienced a case of anastomotic aneurysm of an arterio-venous graft (AVG), which had been created between the BRA and brachial vein. Preoperatively, the AVG was mistakenly interpreted as the one between the brachial artery and vein. Such arterial variants in the upper extremity should be recognized when encountering unusual situations in vascular and endovascular interventions.
