Description
Chitta Ranjan Mohanty and co-authors write a 2026 letter about a surprise blood vessel found during a nerve block. A thirty-year-old man needed finger bone repairs, and the team planned regional anesthesia for his left hand. Ultrasound guiding the median nerve block revealed a pulsing vessel hugging the nerve in the forearm.
Doppler checks confirmed arterial flow, and tracing showed the vessel sprang from the ulnar artery and ran beside the median nerve without straying. That steady parallel course marks a persistent median artery, a leftover vessel most people lose before birth. Finding it mattered: missing it could have meant a punctured artery during the block or later cannulation. The authors stress that point-of-care ultrasound, used with care, catches such variants and keeps nerve blocks both safe and successful.
