This retrospective clinical study reports our results with surgical treatment of chronic median nerve compression at the wrist in 27 hemodialysis patients with a mean follow-up of 22 months. Due to the high incidence of amyloidosis in our patient population, an extensive tenosynovectomy was done in all patients. Statistically significantly (P = .03) better results were obtained when a microsurgical internal neurolysis was added to the procedure, than simple decompression alone (82% vs. 63% good to excellent results).
Ten patients of a population of 319 on chronic intermittent treatment with Cuprophan dialyzers have undergone surgery for carpal tunnel syndrome (CTS). Since 1971 the dialysis schedule for all patients has been 4 m2/h three times per week. All patients were anuric. The operated patients represent 16% of the total population. In comparison with a dialysis population in other units described in the literature (12), 8 m2/h performed three times per week, with similar dialysis aging and a CTS incidence of 47%, it appears that the duration of the dialysis session per se increases the frequency of CTS and leads to the problem of the consequences of blood membrane interaction.
The etiopathology, clinical features, and treatment of carpal tunnel syndrome (CTS) in long-term hemodialyzed patients, are discussed in the light of new clinical findings. Conclusions summarizing the specific characteristics of CTS in hemodialyzed patients include the following. 1) There is a relatively equal sex ratio of patients. 2) The pathogenesis is complex and includes a) the presence of hemodynamic alterations related to the AV fistula; b) the presence of beta 2 M amyloid deposits related to biocompatibility of the dialysis membranes; and c) a correlation between CTS and the duration of hemodialysis related to years and hours/week. 3) A dramatic increase of CTS incidence occurs after five years of dialysis treatment. Prevention as a realistic goal in dialysis CTS is discussed, and specific recommendations are offered by the authors.
We report a case of multiple spontaneous arteries dissection in a 52-year-old female; the patient had a relevant family history of vascular complications and typical features so we hypothesized vascular Ehlers-Danlos syndrome (EDS) that was confirmed by genetic analysis of COL3A1 gene. We adopted a conservative approach: the patient was treated with heparin in the acute phase followed by aspirin and then celiprolol was started on the basis of a recent trial that demonstrates a reduction in arterial events in EDS patient treated. A careful follow-up was done with Doppler ultrasound and computed tomography scan, as non-invasive diagnostic techniques are preferred in these patients, and no other vascular symptomatic events have occurred. We tested all living relatives: half of them had COL3A1 mutation, they were referred to another center specialized in rare diseases and EDS for long-term follow-up and genetic counseling. This case demonstrates as a careful evaluation of clinical signs, clinical history of the patient and his family has allowed a definitive diagnosis, proper management of the patient during the acute event and in terms of prophylaxis of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
