post-catheterization radial pseudoaneurysm at the external surface of the distal forearm measuring 6 x 5 cm in diameter; cyanotic appearance medially represents local ischemic changes due to long-standing severe skin tension (preoperative photo-oblique view)

On clinical examination a remarkable mass was seen, pulsatile and tender, sizing 6 x 5 cm (Figure 1, Figure 2 A, B).

On clinical examination a remarkable mass was seen, pulsatile and tender, sizing 6 x 5 cm (Figure 1, Figure 2 A, B).
both the proximal and distal radial artery have been looped and clamped with bulldog clamps; the sac of the aneurysm is dissected free from the superimposed skin

Under local anaesthesia we removed the sac and evacuated the thrombus (Figure 3, Figure 4, Figure 5, Figure 6).
the fibrous wall of the sac (pseudo-capsule) is opened with a sharp blade; wall thrombus is seen through the incision

Under local anaesthesia we removed the sac and evacuated the thrombus (Figure 3, Figure 4, Figure 5, Figure 6).
part of the sac is removed as well as the thrombus

Under local anaesthesia we removed the sac and evacuated the thrombus (Figure 3, Figure 4, Figure 5, Figure 6).
the lumen of the proximal and the distal radial artery is clearly seen (arrows); a partial transection of the radial artery from the sheath was presumably the causative process for aneurysm formation
