Cerebral venous thrombosis in nephrotic syndrome.

This report describes cerebral venous sinus thrombosis, a rare and perhaps under-diagnosed complication of nephrotic syndrome. We review the pathophysiology of the coagulopathy associated with nephrotic syndrome including abrupt renal loss of antithrombin III. We propose a rationale approach to treating this condition with low-molecular-weight heparin and antithrombin III replacement.
