Key Words: Radial artery • Ulnar artery • Atherosclerosis

We thank Dr Chong [1] for his comments on our recent article [2] and congratulate its group for the nice studies on the effect of radial artery harvesting on the forearm vasculature and haemodynamics.

Removal of the RA anatomically reduces to half the forearm vasculature and the fact that overall forearm flow remains constant is related to the development of ulnar artery collateral flow, as expressed by the increase in systolic velocity in this artery that ourselves and Dr Chong's group have already described.

It is this increase in ulnar flow that could (at least theoretically) have contributed to the development of the ulnar artery atherosclerosis that we have found at long-term follow-up.

However, Dr Chong is not correct when stating that no flow limiting lesions were reported in our study, as overt ulnar atherosclerosis was instead detected in a significant proportion of cases in the operated arm.
