Cognitive impairment and associated risk factors in older adult hemodialysis patients: a cross-sectional survey.

The clinical epidemiological features of cognitive impairment in Chinese older adult patients undergoing hemodialysis are not clear, we aimed to identify the extent and patterns of cognitive impairment among those patients. We conducted a cross-sectional study of 613 hemodialysis patients aged 50 to 80 from 11 centers in Beijing. A neuropsychological battery of 11 tests covering domains of attention/processing speed, executive function, memory, language, and visuospatial function was applied, patients were classified as none, mild, or major cognitive impairment according to the fifth version of the Diagnostic and Statistical Manual of Mental Disorders criteria for cognitive impairment.

One-year patency rate of native arteriovenous fistulas reconstructed by vascular stripping in hemodialysis patients with venous neointimal hyperplasia.

Objective: There are limited therapeutic measures for stenosis of arteriovenous fistulas (AVFs) due to venous neointimal hyperplasia (VNH). In the current retrospective study, we reviewed the clinical data of hemodialysis patients who underwent AVF reconstruction by VNH stripping. The primary measure of interest was the secondary patency rate of the restored AVF.

Restoration of autologous arteriovenous fistula by vascular stripping in a hemodialysis patient with venous neointimal hyperplasia.

A significant number of arteriovenous fistulae fail because of venous neointimal hyperplasia-associated vascular blockage. We developed a surgical technique for repairing arteriovenous fistulae by surgically removing neointimal hyperplasia and vessel re-anastomosis. Here, we report the successful treatment of a case that developed arteriovenous fistula stenosis because of venous neointimal hyperplasia.
