True radial artery aneurysm: A rare cause for finger ischaemia

A 60-year-old man presented to the emergency department with 48 h of pain in the right hand and fingers including the thumb. Examination revealed dusky fingertips with a capillary refill time of 5 s. Both radial and ulnar pulses were present. The patient denied any previous trauma or arterial punctures to the area. Allen’s test suggested radial artery dominant supply. Computed tomography angiography revealed a partially thrombosed aneurysmal segment of radial artery at the wrist (Fig. 1). Duplex ultrasound revealed a heavily calcified 9-mm radial artery aneurysm (RAA) and a 60% ulnar artery stenosis at the wrist. Under regional anaesthetic, the patient underwent a right RAA repair with ipsilateral reversed cephalic vein interposition graft.
