Background And Purpose: Shunt infection represents a particularly morbid condition, which can also result in mortality. In order to decrease the high morbidity and mortality rates, prevention is an essential step. The purpose of this study was to compare the prophylactic use of ceftriaxone and trimethoprim-sulfamethoxazole (SXT) for the prevention of ventriculoperitoneal (VP) shunt infection.
Methods: In this prospective, single-institution, randomized clinical trial, 107 children with hydrocephalus and an indication for shunting were randomly assigned to prophylaxis with ceftriaxone (n = 50) or SXT (55), each administered as a single dose during anesthesia and two divided doses postoperatively. Patients were followed up for at least one year.
Results: The mean age of patients was 15 months, and 85% were aged 6 months or younger. During the first postoperative year, meningitis occurred in 13.5% of patients receiving ceftriaxone and 14.5% of the SXT group, with no statistically significant difference between the groups. Younger age, presence of cerebrospinal fluid leakage and aqueductal stenosis as a cause of hydrocephalus showed significant correlation with meningitis occurrence on univariate analysis. However, only the latter 2 factors were associated with meningitis on multivariate analysis. The risk of shunt infection did not correlate with the gender of the patient, time of VP shunt surgery, or duration of hospitalization for shunting.
Conclusion: Ceftriaxone and SXT showed similar efficacy in preventing shunt infection. Cerebrospinal fluid leakage before or after VP shunt placement and aqueductal stenosis were independent risk factors for meningitis after VP shunt.

Objective: Intraventricular hemorrhage (IVH) is a serious condition with high mortality rates and poor functional outcome in survivors. Treatment includes external ventricular drains (EVDs), which are associated with several complications. This study reports the clinical outcome and complication rate in patients with primary IVH (pIVH) and secondary IVH treated with EVDs.

Ventriculoperitoneal shunts (VPSs) have been proven to be life-saving procedures, but their complications pose challenges, particularly in this era of rising antibiotic resistance. We report a critically ill case with VPS infection due to colistin-resistant that was treated with intraventricular tigecycline as salvage therapy without adverse events, resulting in microbiologic cure and clinical response. The use of intraventricular tigecycline in the treatment of colistin-resistant appears promising; however, appropriate dosage adjustments and evidence-based recommendations are needed.

Purpose: Arachnoid cysts constitute approximately 1 % of intracranial mass lesions, with quadrigeminal cistern arachnoid cysts being 5-18 % of those. This study presents a series of 31 cases of quadrigeminal cistern arachnoid cysts, constituting the most extensive series reported to date.
Methods: A retrospective analysis was conducted on 31 patients diagnosed with quadrigeminal cistern arachnoid cysts, focusing on clinical presentation, demographics, treatment approaches, and outcomes.

Objective: The key to increasing the success rate of limb preservation lies in timely restoration of the blood supply to the severed limb, This study examines the clinical effect of a disposable intravenous infusion device as a temporary vascular shunt device which can quickly restore blood circulation in the replantation of severed limbs.
Methods: A retrospective review of all amputated major limbs in our department from May 2005 to May 2022. Patients treated with intravenous infusion tubes as temporary vascular shunt devices were included in group A(shunt group ) and those who could not use temporary intravascular shunt devices were included in group B (no shunt group).

BACKGROUND Ventriculoperitoneal (VP) shunt surgery is a widely used procedure for managing hydrocephalus; however, postoperative infections remain a serious complication, increasing morbidity and mortality. Known risk factors include prior surgeries, steroid use, and concurrent procedures. However, the role of liver cirrhosis, a condition that compromises immune function and predisposes patients to infections, has not been fully investigated in the context of neurosurgery.
