There appear to be no reports to date indicating any relationship between the use of alternate-day steroid therapy and thromboembolic phenomena, let alone the relationship of these factors to temporal arteritis. We report two cases of thromboembolic complications occurring during prednisone treatment of temporal arteritis. Demonstration of a causal link awaits further study, for the association reported here may be due to chance. Our intent is only to alert other physicians to the possibility of such a link.
