Background: One of the most feared complications of hydrocephalus is shunt migration. Although rare, bowel migration is the most commonly encountered type of migration. The relatively high frequency of this occurrence allowed us to gather a substantial number of reports for study.
Objectives: The aim of this study was to better understand this complication and aid in decreasing its incidence.
Methods: The PubMed and Scopus databases were searched for cases of anal shunt migration. In total, 49 records describing 56 clinical cases were included in this review. Additionally, we present and include the clinical case of a patient managed by our team; therefore, 57 cases were included in this study. Relevant parameters were collected, organized, analyzed, and discussed. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement from 2009.
Results: Extrusion through the anus was observed in 82% of cases, 68% of which were in males. The age range varied from 1 month to 75 years. Congenital hydrocephalus was the etiology in 66% of cases. The time interval between shunt insertion and migration varied from 12 days to 19 years. In 70% of patients, the tube was pulled out through the anus, whereas a laparotomy or laparoscopy was used in 14% of cases. Infectious complications were noted in 35% of patients. The overall outcome was mostly favorable; two patients died as a complication of the migration.
Conclusions: Bowel and anal shunt migration is a relatively rare complication occurring predominantly within the initial weeks after the initial surgery. This condition leads to infectious complications, which can potentially be life-threatening. Urgent management is required, and in most cases, the removal of the shunt through the anus is sufficient. Early intervention generally results in favorable outcomes.

Background: Children and young people (CYP) with primary brain tumour (PBT) are at high risk for developing late effects, potentially affecting long-term quality of life (QoL). In low-income and middle-income countries, QoL has not been studied in depth in CYP. In the present study, CYP treated for PBTs in Pakistan were evaluated regarding (A) mean change in QoL scores pretreatment and 12 months post-treatment and (B) predictors of change in QoL scores 12 months post-treatment.

Background: Intrathoracic migration of a ventriculoperitoneal shunt (VPS) is a phenomenally rare complication, with the supradiaphragmatic intercostal variant even more so. Whereas it can prove debilitating or even fatal via massive hydrothorax, the causative mechanism and proper management of this occurrence are undefined.
Case Presentation: A 17-month-old girl who had undergone VPS insertion at one month of age was brought to our department for somnolence and dyspnea, which had a sudden onset.

Article Synopsis
- - Arteriovenous fistula (AVF) is the ideal vascular access for patients undergoing hemodialysis, created by surgically connecting an artery and vein, but research indicates that many do not function beyond a year.
- - This study utilized fluid-structure interaction (FSI) modeling to analyze non-Newtonian blood flow in a specific type of AVF over a 15-week and 1.5-year period, assessing both hemodynamic changes and wall alterations through ultrasound.
- - Key findings included the presence of counter-rotating vortices affecting pressure, different patterns of blood flow characteristics over time, minimal low-wall shear stress in healthy AVFs, and shifts in areas of maximum wall deformation as time
Purpose: Based on an initial hypothesis that the abdominal radiograph is rarely useful in the radiographic shunt series (SS), this study sought to determine which components of the SS are useful in identifying and diagnosing shunt dysfunction. This enquiry broadened to evaluate which modalities were most clinically useful in patients who ultimately underwent shunt revision for their suspected dysfunction.
Methods: Arm1: Abdominal radiographs (AXR) performed over a 2-year period were reviewed retrospectively to identify shunt abnormalities.
