An 83-year-old male patient with ventriculoperitoneal shunt underwent radionuclide shunt study using single-photon emission computed tomography/computed tomography (SPECT/CT) to evaluate the shunt patency. The planar images showed activity at the cranial region and spinal canal but no significant activity at the peritoneal cavity. However, SPECT/CT images clearly demonstrated accumulation of activity at the superior part of bifurcation level with no activity at the distal end of shunt as well as no spilling of radiotracer into the peritoneal cavity indicating shunt obstruction. SPECT/CT makes the interpretation of radionuclide shunt study more accurate and easier as compared with traditional planar images.

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.

Electronic address:
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.
