Abstract
This retrospective study was designed to investigate the prevalence, characteristics and natural history of cold intolerance after the use of the reverse digital artery flap. A total of 123 patients were treated between 2010 and 2013. After excluding patients who were lost to follow-up, 87 patients were studied. The mean follow-up time was 34 months (range 14–61). Cold intolerance occurred in 60% (52) of patients after the reverse digital artery flap procedure. The condition improved in only 15% (8) of the patients. Significant differences were observed in the age and the specific digit involved between the groups with and without cold intolerance. There was a lower incidence in younger patients, and the ring finger group showed a lower incidence than in other fingers. Furthermore, the Cold Intolerance Symptom Severity score was positively correlated with the temperature at which cold intolerance was triggered.
