Shunt Dependence after Intraventricular Hemorrhage and Intraventricular Fibrinolysis with uPA versus rt-PA.

BACKGROUND: We compare the effect of urokinase (urokinase-type plasminogen activator [uPA]) versus alteplase (recombinant tissue plasminogen activator [rt-PA]) for intraventricular fibrinolysis (IVF) in patients with intraventricular hemorrhage (IVH) on ventriculoperitoneal shunt (VPS) dependence, functional outcome, and complications in the management of IVH. METHODS: We retrospectively reviewed the patients admitted with IVH or intracerebral hemorrhage (ICH) with IVH within 7 years in three different departments and found 102 patients who met the inclusion criteria. The primary end points were VPS dependence and Glasgow outcome score (GOS) at 3 months. Secondary end points were rate of rebleeding under IVF and incidence of treatment-related complications. Patients were divided into three groups: group I comprised patients treated with external ventricular drain (EVD) and IVF with uPA; group II comprised patients treated with EVD and IVF with rt-PA; and group III comprised patients treated with EVD alone. RESULTS: In all, 9.8% patients needed VPS: 12.2% in group I and 15.0% in group II, with no statistically significant difference. VPS patients had higher values of the modified Graeb score (mGS), IVH score, and IVH volume. We saw a trend for a better outcome in group II, with six patients achieving a GOS of 4 or 5 after 3 months. The mortality rate was higher in groups I and III. We found no statistical difference in the complication rate between groups I and II. Logistic regression analysis revealed that higher mGS and age predicted worse prognosis concerning mortality. The risk for death rose by 7.8% for each year of age. Any additional mGS point increased the chances of death by 9.7%. CONCLUSION: Our data suggest that both uPA and rt-PA are safe and comparable regarding incidence of communicating hydrocephalus, and age and mGS are predictive for mortality.

Atypical Presentation of Neurobrucellosis as Infection of Ventriculoperitoneal Shunt.

Brucellosis is a frequent zoonosis in some regions of the world and may cause various symptoms. Neurobrucellosis is a rare but serious complication of the infection. Our case report describes the course of neurobrucellosis in a patient who had received a ventriculoperitoneal shunt in his native country 13 years prior to diagnosis of brucellosis. He initially presented to us with symptoms of peritonitis, which misled us to perform abdominal surgery first. After the diagnosis of neurobrucellosis was confirmed and appropriate antibiotics were initiated, the symptoms soon disappeared. Although the ventriculoperitoneal shunt was subsequently removed, the patient did not develop a symptomatic hydrocephalus further on. This case displays the challenges in diagnosing an infection that occurred sporadically in Europe and may be missed by currently applied routine microbiological workup. Considering the political context, with increasing relocation from endemic areas to European countries, it is to be expected that the cases of brucellosis and neurobrucellosis will rise. Brucellosis should be considered and adequate investigations should be performed.
