Curative effect and complication of neuronavigation guided puncture ventricle peritoneal shunt and traditional ventriculoperitoneal shunt for hydrocephalus

Abstract

Objective To compare the accuracy of placement of ventricular shunt tube, the efficacy and complications of the neuronavigation-assisted ventriculoperitoneal shunt (group A) and traditional ventriculoperitoneal shunt (group B). Methods A retrospective study was made on 40 cases of hydrocephalus managed with neuronavigation-assisted ventriculoperitoneal shunt or ventriculoperitoneal shunt from January 2012 to June 2016. There were 18 cases [12 males, 6 females; (47.5±8.5) years of age] in group A and 22 cases [14 males, 8 females; (44.5±7.5) years of age] in group B. Therapeutic effect and complications were analyzed postoperatively. The accuracy rate in ventricular end shunt placement that was free from the frontal horn of lateral ventricle and flush the Moro hole had also been studied. Results The position of ventricular shunt of all the patients were postoperative timely review of the CT view, and hospital outpatient follow-up periodical for 3-24 months after discharge from hospital. Patients with postoperative timely review of head CT and found that group A of ventricular end of the shunt tube position reach a set position in 16 cases, 2 cases had not reached the set position, the accuracy rate was 88.89%. There were 8 cases in group B reach to the set position and 14 cases did not and the accuracy rate was 36.36%. After the statistical analysis there were significant differences (P 0.05). Postoperative complications included bleeding, infection, obstruction of the shunt, excessive shunt, shunt insufficiency and so on. During follow-up, group A appeared excessive shunt in 1 case; group B incision infection in 1 case, 4 cases of shunt obstruction, excessive shunt in 1 case, 2 cases of deficiency of shunt. Two groups of patients were recovery well through the drainage tube pressure adjustment or set it once again. The incidence of complications in group A was 5.56%, group B was 36.36%. There was no significant difference between group A and group B (P>0.05). In group A, there was no obstruction of shunt tube, ventricular end of the shunt tube blockage occurred in 4 cases in group B, the incidence rate was 18.18%(P>0.05). Conclusion Neuronavigation guided ventriculoperitoneal shunt placement to the accuracy of position setting has significant advantages over traditional ventriculoperitoneal shunt in the ventricular end of the shunt tube and it has some advantages in reducing postoperative complications.
