ABSTRACT
Objective To develop a capacity-controlled ventriculoperitoneal shunt device to relieve the symptoms of hydrocephalus patient.Methods The device was composed of head-end shunt tube,middle reservoir and celiac shunt tube.The ends of the reservoir were equipped with one-way valve to drive cerebrospinal fluid to celiac shunt tube in case of the pressure on the reservoir.The capacity-controlled drainage of cerebrospinal fluid was implemented through the times of the pressure.Results The device drained cerebrospinal fluid to relieve the symptoms of hydrocephalus patient,and the complications due to over-or under-drainage were eliminated.Conclusion The device gains advantages in design and easy operation,and is an effective and safe shunt choice for types of hydrocephalus patients.
ABSTRACT
Objective To explore the efficacy of minimally invasive surgery in elderly patients with cerebral hemorrhage.Methods Clinical data of hypertensive cerebral hemorrhage patients who were older than 65 years were retrospectively analyzed,and they were divided into two groups by different surgical methods.Regular group:from March 2010 to February 2011,123 cases of conventional bone window surgery.Minimally invasive group:from March 2011 to February 2012,136 cases of minimally invasive surgery.One month after surgery,two groups of patients with the scores of Glasgow outcome scale (GOS) to determine the prognosis.Results The better prognosis rate in minimally invasive group was higher than that in regular group [39.7％(54/136) vs.29.3％(36/123)],but there was no significant difference (P ＞0.05).The incidence rate of death in minimally invasive group was significantly lower than that in regular group [17.6％ (24/136) vs.28.5％ (35/123)],and there was significant difference (P ＜ 0.05).Conclusion For elderly patients with cerebral hemorrhage,the minimally invasive surgery can significantly improve the prognosis.
