OBJECT The purposes of this study were to evaluate the frequency with which children presented with ventriculoperitoneal (VP) shunt perforations of the gastrointestinal (GI) tract, to determine the type of shunts that caused the perforations, and to compare the stiffness of perforating catheters with the stiffness of catheters from other manufacturers. METHODS Medical records were reviewed of 197 children who were admitted with VP shunt malfunction. Catheter stiffness was evaluated by measuring relative resistance to cross-sectional compression, resistance to column buckling, and elasticity in longitudinal bending. Catheter frictional force was measured per unit length. RESULTS Six children were identified whose VP shunts had perforated the GI tract; 2 shunts subsequently protruded through the anal orifice, 1 protruded through the oral cavity, and 3 presented with subcutaneous abscesses that tracked upward from the intestine to the chest. All perforating shunts were Chhabra shunts. Catheter stiffness and resistance to bending were greatest with a Medtronic shunt catheter, intermediate with a Codman catheter, and least with a Chhabra catheter. Frictional force was greatest with a Chhabra catheter and least with a Medtronic catheter. CONCLUSIONS The frequency of perforations by Chhabra shunts appears to be higher than the frequency associated with other shunts. The increased frequency does not correlate with their stiffness but may reflect their greater frictional forces.

The objective of this study was to evaluate the demographic, clinical, laboratory, and microbiological features of ventriculoperitoneal shunt (VPS) infections through a 13-year retrospective study. VPS bacterial agents and their antibiotic susceptibility were also investigated through the occurrence of single VPS (SVPS) and recurrent VPS (RVPS) infections. This study included 110 patients with SVPS infections and 55 patients with RVPS infections.

Background/objectives: Ventriculoperitoneal shunting is a validated procedure for the treatment of idiopathic normal-pressure hydrocephalus. To select shunt-responsive patients, infusion and tap tests can be used. Only gait is evaluated after the procedure to establish a potential improvement.

Shunt dependence syndrome is a serious long-term complication characterized by symptoms and signs of increased intracranial pressure with normal-sized lateral ventricles after several years of arachnoid cyst-peritoneal shunting. It is easy to misdiagnose and overlook when combined with sinus stenosis, thus delaying treatment. Here, we present a 35-year-old man with an unexplained headache and binocular horizontal diplopia with high intracranial pressure.

Objective: This study was conducted to evaluate the time gap between earliest head CT with a significant Radscale score and ventriculo-peritoneal (VP) shunt placement.
Material And Methods: The study is a retrospective observational analytic study. The study population includes idiopathic normal pressure hydrocephalus (iNPH) patients treated with a VP shunt in a single center between the years 2016 and 2022 and have at least 2 CTs, one in proximity to diagnosis and another obtained at an earlier time point.

Background: The optimal duration of external ventricular drain (EVD) in patients with aneurysmal subarachnoid hemorrhage (aSAH) is debatable. We sought to determine the association of EVD duration and output with outcomes, including cerebral infarct.
Methods: We performed a retrospective study of a prospectively collected cohort of consecutive patients with aSAH who were admitted to an academic center from 2016 to 2023.
