Insights
Ventriculoperitoneal shunting for hydrocephalus can lead to abdominal pseudocysts (APC), a rare but serious complication. This case highlights APC diagnosis and management in a pediatric patient, emphasizing prompt surgical intervention.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Gastroenterology
Background:
- Ventriculoperitoneal (VP) shunting is a primary treatment for hydrocephalus.
- Complications associated with VP shunts are well-documented, with abdominal pseudocysts (APC) being uncommon yet significant.
- Understanding APC is crucial for managing VP shunt patients.
Observation:
- A 9-year-old boy presented with symptoms including abdominal distension, pain, malaise, and appetite loss.
- Abdominal pelvic computed tomography confirmed the presence of an abdominal pseudocyst.
- The patient underwent a laparotomy for APC management and VP shunt repositioning.
Findings:
- Abdominal Pseudocyst (APC) is a rare complication of Ventriculoperitoneal (VP) shunting.
- Clinical presentation includes abdominal symptoms like distension and pain.
- Imaging (CT scan) is key for diagnosis, followed by surgical intervention.
Implications:
- Early diagnosis and surgical management of APC are vital for patient recovery.
- Repositioning the VP shunt is often necessary after APC treatment.
- This case underscores the importance of considering APC in VP shunt patients with abdominal complaints.
Abstract:
Ventriculoperitoneal (VP) shunting is mostly used in the treatment of hydrocephalus and many complications have been reported with this method. Abdominal Pseudocyst (APC) are relatively uncommon but important complications in patients with VP shunts. We herein report the case of a 9-year-old boy with VP shunt who presented with abdominal distension, abdominal pain, malaise, and decrease of appetite. Abdominal pelvic computed tomography confirmed a diagnosis of APC. Laparotomy was done and VP shunt was placed into the other side of peritoneal cavity again. Also here, etiology, presentation, diagnosis, and treatment of APC were reviewed.
