CSF diversion in benign intracranial hypertension using a lumbo-atrial shunt

Area of Science:

• Neurosurgery
• Bariatric Surgery
• Medical Device Management

Background:

• Management of benign intracranial hypertension (BIH) in obese patients often involves cerebrospinal fluid (CSF) shunting.
• Lumbo-peritoneal (LP) shunting is a common surgical intervention for BIH.
• Obesity and prior abdominal surgeries can increase the risk of intra-abdominal adhesions.

Observation:

• A patient with obesity and BIH experienced recurrent LP shunt failures.
• These failures were attributed to dense peritoneal adhesions following a bilopancreatic diversion procedure for obesity management.
• The existing shunt system required revision due to the complications arising from adhesions.

Findings:

• Successful conversion of the failed LP shunt system to a lumbo-atrial (LA) shunt was achieved.
• The LA shunt provided a viable alternative when peritoneal complications compromise LP shunt function.
• This case highlights the importance of considering alternative shunt pathways in patients with complex abdominal conditions.

Implications:

• Lumbo-atrial shunting can be an effective alternative for managing benign intracranial hypertension when abdominal adhesions prevent successful lumbo-peritoneal shunting.
• Surgical planning for obese patients undergoing bariatric procedures should consider potential impacts on existing CSF shunts.
• This approach may improve long-term outcomes for patients requiring CSF diversion in the presence of significant intra-abdominal pathology.
