Abstract: 
Background: Hydrocephalus is a condition in which there is an abnormal build-up of cerebrospinal fluid within the ventricles and/or subarachnoid space, which leads to elevated intracranial pressure (ICP). VEGF is the prime hypoxia inducible angiogenic factor. We assumed that increased ICP leads to reduced oxygen tension in brain tissue, which triggers VEGF gene transcription so, in the current work we aimed to study VEGF alternation in hydrocephalus.
Material and Method: Measurements were performed on CSF and serum aliquots obtained from control (n=20) and hydrocephalic patients (n=25), ageand sex-matched, were collected by lumbar puncture (LP) in the children hospital medical center of Tehran from 2006 to 2008. VEGF and total protein concentrations were determined by enzyme-linked immunosorbent assays (ELISA) and Bradford method, respectively.
Results: VEGF and total protein concentrations were significantly elevated in hydrocephalus CSF samples compared with those in controls (p<0.05, p<0.001, respectively). There was only a slight insignificant elevation in serum VEGF concentrations.
Conclusion: Under normal conditions there is only diffuse expression of VEGF in the brain. In contrast, under local or systemic hypoxia, neurons, astrocytes, and microglial cells all show enhanced VEGF expression. The present study shows that VEGF concentrations are much higher in the CSF of children with hydrocephalus than in control samples and VEGF may be involved in hydrocephalus pathophysiology.
