- β-Trace Protein as a Potential Biomarker for CSF-Venous Fistulas
This prospective study of patients with CVF compared the levels of β-trace protein (BTP) in paraspinal veins near the CVF with those in the peripheral blood and in the peripheral blood of controls. Venous blood at the site of the CVF was shown to have higher BTP values compared with peripheral blood in most patients with CVF. It was also found that patients with CVF had a lower peripheral blood BTP level compared with controls.
