Oxalosis in chronic renal failure.

The incidence and severity of oxalate deposition as a complication of chronic renal failure in a retrospective study of 73 patients is presented. The reason for this study was the occurrence of a syndrome characterised by multiple shunt-complications, muscle weakness and peripheral ulceration in three haemodialysis patients. This syndrome seems to be caused by an obliterative vasculitis due to oxalate deposition in the media of peripheral vessels (Figure 1).
