Insights
Cerebrospinal fluid (CSF) diversion procedures can rarely lead to pseudoaneurysms. This case highlights a pericallosal artery pseudoaneurysm after ventricular catheter placement, emphasizing a rare but serious risk.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Vascular Surgery
Background:
- Complications following cerebrospinal fluid (CSF) diversion are varied.
- Pseudoaneurysm formation after ventricular catheter placement is considered rare.
Observation:
- A child developed a pericallosal artery pseudoaneurysm after endoscopic ventricular catheter insertion for a ventriculoperitoneal shunt.
- Intraventricular bleeding indicated vascular injury, confirmed by angiography revealing a right pericallosal artery pseudoaneurysm.
Findings:
- This is the first reported case of pseudoaneurysm formation linked to ventricular catheter placement for CSF diversion.
- The patient required surgical trapping of the pseudoaneurysm and physical therapy for resulting leg weakness.
Implications:
- This case underscores a rare but significant risk associated with routine CSF shunt procedures.
- Highlights the importance of vigilance for vascular complications during and after CSF diversion surgery.
Abstract:
Complications following cerebrospinal fluid (CSF) diversion procedures are protean. The formation of pseudoaneurysms after the placement of a ventricular catheter as part of a CSF diversion procedure is presumably quite rare. The authors report the case of a child in whom a pericallosal artery pseudoaneurysm developed following the endoscopic insertion of a ventricular catheter as part of a ventriculoperitoneal shunt placement procedure. Significant intraventricular bleeding signaled vascular injury. Angiography revealed a right pericallosal artery pseudoaneurysm. The patient subsequently underwent surgical trapping of his pseudoaneurysm and physical therapy for left leg monoparesis. This appears to be the first reported case of pseudoaneurysm formation following the placement of a ventricular catheter for a CSF diversion procedure. This case underlines a rare but serious risk involved with the routine placement of CSF shunts.
