Abstract:
Objective:To observe the clinical characteristics of pressure regulation frequency of shunt pump in patients with hydrocephalus after ventriculoperitoneal shunt, and explore the correlation between frequencies of shunt pump and prognoses of these patients.Methods:One hundred and one patients underwent ventriculoperitoneal shunt in our hospital from January 2018 to December 2018 were selected. According to the frequencies of postoperative pressure regulation of these patients, they were divided into non-pressure regulation group, low-frequency pressure regulation group (1-2 times) and high-frequency pressure regulation group (2 times or more). The relations of high-pressure hydrocephalus/normal pressure hydrocephalus with pressure regulation frequency, and relation between causes of pressure regulation and pressure regulation frequency were compared, and the prognoses of patients with different pressure regulation frequencies were analyzed.Results:Among the 101 patients with implanted adjustable pressure shunt, 34 had no pressure regulation after surgery, 52 had low-frequency pressure regulation, and 15 had high-frequency pressure regulation. The percentages of patients accepted low-frequency pressure regulation and high-frequency pressure regulation in patients with high-pressure hydrocephalus were significantly higher than those with normal pressure hydrocephalus ( P<0.05). The proportions of patients with insufficient shunt, excessive shunt or magnetic field interference in the low-frequency pressure regulation group were significantly higher than those in the high-frequency pressure regulation group ( P<0.05), while the proportions of patients with abnormal shunt (stagger of insufficient shunt, excessive shunt) in the low-frequency pressure regulation group were significantly lower than those in the high-frequency pressure regulation group ( P<0.05). There were 7 patients with poor curative effect, including 4 patients from the low-frequency pressure regulation group and 3 from the high-frequency pressure regulation group. The prognoses of patients with different pressure regulation frequencies were statistically different( P<0.05), the good prognosis rate of patients in the non-pressure regulation group, low-frequency pressure regulation group and high-frequency pressure regulation group decreased successively. Conclusion:About 66.3% patients need pressure regulation treatment again after hydrocephalus-ventriculoperitoneal shunt; the rate of poor efficacy in patients accepted high-frequency pressure regulation is obviously higher than that in patients accepted low-frequency pressure regulation, which needs clinical attention.
