title: Cold induced vasospasm in replanted digits: a comparison between different methods of arterial reconstruction.
abstract: Nineteen patients each of whom had had a single digit replanted were examined after replantation. The arterial reconstruction had been done with long grafts (n = 10) or short grafts or no graft (n = 9). The effect of local or whole body cooling on the replanted and uninjured opposite digits was monitored (9-46 months after the replantation), and the patients were given a questionnaire (9-95 months after replantation) designed to explore the development of their cold related symptoms in relation to time. All patients were troubled by cold intolerance, and improvement occurred in only 60% of the cases. Pathological (vasospastic) arterial reactions to cold measured as finger systolic pressure, were less common after replantation with long grafts. Perceived cold intolerance was significantly more pronounced in the group of patients (60%) who had evidence of cold induced arterial spasm in the replanted finger.
