Lumbar and ventricular CSF concentration of homovanillic acid (HVA) and 5-hydroxy-indole-acetic acid (5-HIAA) have been determined in 13 patients admitted to hospital for suspected normal pressure hydrocephalus. Low values of HVA in lumbar CSF were found in all patients with reduced CSF absorption and CSF flow inversion. The HVA lumbar concentration remained low after shunt procedure; it increased if obstruction of the shunt occurred. The ventricular CSF concentration of HVA was normal before surgery; it became higher, in two cases, after surgery. No important variations were found in the lumbar and ventricular CSF concentration of 5-HIAA. The possible mechanisms and diagnostic value of these findings are discussed.
对13名因疑似正常压力脑积水入院的患者测定了腰椎和脑室脑脊液中高香草酸(HVA)和5-羟吲哚乙酸(5-HIAA)的浓度。在所有脑脊液吸收减少和脑脊液流动逆转的患者中,腰椎脑脊液中的HVA值均较低。分流手术后,腰椎脑脊液中HVA的浓度仍较低;如果分流管发生阻塞,其浓度会升高。术前脑室脑脊液中HVA的浓度正常;术后有两例升高。5-HIAA在腰椎和脑室脑脊液中的浓度未发现明显变化。讨论了这些发现的可能机制和诊断价值。
