透析患者における手根管症候群再発例の検討

Abstract

Over a three year period (1994-1996), we performed 18 carpal tunnel releases in long-term hemodialysis patients. Six of these patients were a second carpal tunnel release group, with their symptoms recurring 1 to 8 years (mean: 4.3 years) after their first carpal tunnel release. In this study we reviewed the difference between the first carpal tunnel release group and the recurrent group.Although, there was no significant difference between the two groups in regard to preoperative objective symptoms and the number of distal motor latencies, complications appeared to be a prominent feature in the recurrent group.Microscopic examination showed amyloid depositions in the membranous tissue surrounding the median nerve in the recurrent group and this may cause the recurrence of symptoms.We conclude that it is necessary to follow patients after re-operation because factors which prevent recurrence are still unclear.
