Introduction: One of the nightmares of placing a shunt in patients with friable skin is an exposed shunt or shunt valve with risk of infection of the hardware which may lead to meningitis or ventriculitis with poor outcome. Another feared complication is cerebrospinal fluid (CSF) leak from the wound with subsequent wound dehiscence. The patients at risk of shunt hardware exposure include children who have fragile skin or skin at risk (either from prematurity, malnutrition, steroid therapy or very large head with pressure on the skin).
Method/technique: This technique involves making a scalp incision with the pericranium taken in one layer with the galea or if the galeal flap has been raised, a pericranial incision is made and a pericranial flap is raised. A subpericranial pouch is developed and a shunt passer used to tunnel the shunt to the abdomen. The pericranial layer is closed, the galea and subcutaneous layer also approximated, and a continuous subcurticular stitch applied.
Result: We present a malnourished infant with postinfective hydrocephalus having a thin skin requiring a ventriculoperitoneal shunt. A subpericranial technique was used and the patient did well.
Conclusion: This technique is simple and provides a water-tight wound cover, with the pericranium giving reinforcement and better tensile strength, as well as a fairly good protection for the shunt valve. This is useful in preventing CSF leaks and exposure of the shunt with the associated morbidity and mortality.

Nonadjustable state of programmable shunt valve: obstruction of middle cranial fossa arachnoid cyst-peritoneal shunt.
Chin Neurosurg J

Department of Neurosurgery, Hebei Children's Hospital, Hebei Medical University, Shijiazhuang, Hebei, China.
Background: A nonadjustable state of the programmable shunt valve is a rare phenomenon. This case report aims to explore the cause of pressure adjustment dysfunction in a programmable shunt valve in a middle cranial fossa arachnoid cyst-peritoneal shunt patient and to underscore this dysfunction as an indicator of shunt valve obstruction.
Case Presentation: A child with a ruptured giant arachnoid cyst in the left middle cranial fossa presented with acute intracranial hypertension following head trauma.
Intraoperative Hemodynamic Instability in a Patient With Ebstein's Anomaly Complicated With Eisenmenger Syndrome.

Ebstein's anomaly is a rare congenital displacement of the tricuspid valve resulting in atrialization of the right ventricle. About half of the patients with Ebstein's anomaly also have atrial septal defects, which may lead to chronic shunting and development of Eisenmenger syndrome. We describe a case of a sexagenarian male patient with a history of Ebstein's anomaly complicated with Eisenmenger syndrome undergoing robotic laparoscopic adrenalectomy who presented hemodynamic instability, hypoxemia, and likely right-to-left shunting intraoperatively, as well as the actions taken to correct it and have a successful outcome.

Background: In patients with adult congenital heart disease (ACHD), significant atrioventricular valve regurgitation is an important risk factor for poor outcomes, such as heart failure. However, in many cases, transcatheter intervention may reduce the risk profile to avoid a high surgical risk.
Case Summary: A 44-year-old man with complex ACHD in the form of a double-inlet left ventricle, congenitally corrected transposition of the great arteries, pulmonary atresia, atrial septal defect, and patent ductus arteriosus was referred for the treatment of severe tricuspid regurgitation.
The evolution of ventriculoperitoneal shunt valves and why they fail.
World Neurosurg
December 2024
Department of Mechanical, Aerospace, and Biomedical Engineering, The University of Tennessee, Knoxville, Tennessee, United States of America. Electronic address:
This paper reviews the historical progression of ventriculoperitoneal shunt valve designs with the goal of providing an understanding of their functionality and failure mechanisms. While shunting is the predominant treatment for hydrocephalus, the statistics of overall shunt failure remain high, and valve failure is responsible for a significant percentage of revision surgeries. Therefore, this review spans valve evolution from an engineering perspective with an emphasis on discussing potential failure mechanisms and patient specific valve selection.

A circular shunt, initially described by Shone et al. in 1962, refers to abnormal blood recirculation through complete intracardiac or intra- and extracardiac communications, bypassing the capillary beds. This pathophysiological condition is most commonly associated with complex congenital heart defects, such as Ebstein's malformation, pulmonary atresia, Gerbode defect, and so on.
