Pleural effusion in a child with a ventriculoperitoneal shunt and congenital heart disease

Chronic Pleural Effusion in Ventriculoperitoneal Shunt due to Diaphragmatic CSF Fistula: Report of a Case Treated by Endoscopic Choroid Plexus Coagulation and Literature Review

INTRODUCTION

Chronic pleural cerebrospinal fluid (CSF) effusion is a rare complication after ventriculoperitoneal (VP) shunt insertion and only 18 cases in children and adults have been described so far without catheter dislocation to the intrathoracic cavity.

CASE PRESENTATION

We report on a 4-year-old girl with a complex history of underlying neurogenetic disorder, a hypoxic-ischemic encephalopathy after influenza A infection with septic shock and severe acute respiratory distress syndrome, followed by meningitis at the age of 10 months. In consequence, she developed a severe cerebral atrophy and post-meningitic hydrocephalus requiring placement of a VP shunt. At age 4, she was admitted with community-acquired mycoplasma pneumonia and developed increasing pleural effusions leading to severe respiratory distress and requiring continuous chest tube drainage (up to 1,000-1,400 mL/day) that could not be weaned. β trace protein, in CSF present at concentrations >6 mg/L, was found in the pleural fluid at low concentrations of 2.7 mg/L. An abdomino-thoracic CSF fistula was finally proven by single photon emission computerized tomography combined with low-dose computer tomography. After shunt externalization, the pleural effusion stopped and the chest tube was removed. CSF production rate remains high above 500 mL/24 h. An atrial CSF shunt could not be placed, since a hemodynamically relevant atrial septum defect with frail circulatory balance would not have tolerated the large CSF volumes. Therefore, she underwent a total bilateral endoscopic choroid plexus laser coagulation (CPC) within the lateral ventricles via bi-occipital burr holes. Postoperatively CSF production rate went close to 0 mL and after external ventricular drain removal no signs and symptoms of hydrocephalus developed during a follow-up of now 2.5 years.

CONCLUSION

In summary, pleural effusions in patients with VP shunt can rarely be caused by an abdomino-thoracic fistula, with non-elevated β-trace protein in the pleural fluid. The majority of reported cases in literature were treated by ventriculoatrial shunt. This is the 2nd reported case, which has been successfully treated by radical CPC alone including the temporal horn choroid plexus, making the child shunt independent.

Management of Hydrocephalus in Children: Anatomic Imaging Appearances of CSF Shunts and Their Complications

OBJECTIVE. This article addresses the management of hydrocephalus and the CSF shunts used to treat this entity. CONCLUSION. CSF shunts have a high failure rate. Imaging plays a pivotal role in assessing CSF shunt failure and determining the need for surgical revision. An in-depth knowledge of CSF shunt components, their failure modes, and the corresponding findings on anatomic imaging studies is necessary to ensure timely diagnosis and prevent permanent neurologic damage.

Ventriculoperitoneal shunts: What nurses need to know

A ventriculoperitoneal shunt (VPS) is the most common type of implanted cerebrospinal fluid shunt system. Nurses may care for patients who have undergone shunt placement or revision. This article discusses the indications for VPS placement in adults, possible complications, and nursing care for patients following a shunt placement procedure.

[Hydrothorax as a complication of a ventricle peritoneal shunt. A case report]

The ventricle peritoneal (VP) shunt is commonly used in the treatment of hydrocephalus. It is a relatively simple and effective technique, but around 70% of the patients with a VP shunt have a complication in their lifetime. Most of these complications are due to infection or mechanical dysfunction. The thoracic complications are rare. The present case is one of the small number of them found in the literature, describing hydrothorax as a complication of a VP shunt without catheter migration and without ascites. The case is presented of a 2 year-old girl with VP shunt. The patient was diagnosed with pleural effusion compatible with hydrothorax. After finding beta-2-transferrin in the pleural fluid, it was it was shown to be from cerebrospinal fluid. Cranial CT showed the catheter in a proper position, and the Xray and ultrasound showed the catheter correctly positioned in the peritoneum.
