| pubmed-article:18325424 | pubmed:abstractText | Historically, hyponatremia in patients with varying brain diseases was termed cerebral salt wasting. Hyponatremia secondary to CSW was reported to be a distinct entity from SIADH, with the distinguishing feature of decreased extracellular fluid volume. Brain natriuretic peptide, a peptide with natriuretic, vasorelaxant, and aldosterone-inhibiting properties, was recently implicated in aneurysmal SAH patients with CSW. Here, we describe 2 cases of CSW in TBI patients with elevated BNP levels. This phenomenon has not been previously described. | lld:pubmed |
