Stopping CSF leaks at external ventricular drain exit sites: a technical note.

Area of Science:

• Neurosurgery
• Infectious Disease Prevention

Background:

• Cerebrospinal fluid (CSF) leaks at external ventricular drain (EVD) sites are a significant risk factor for serious infections.
• Preventing CSF leaks is crucial for improving patient outcomes and reducing complications associated with EVD placement.

Purpose of the Study:

• To present a novel surgical technique designed to minimize the incidence of CSF leaks at the EVD exit site.
• To offer a solution for high-risk patients susceptible to EVD-related complications.

Main Methods:

• The technique involves the circumferential placement of vertical mattress sutures around the EVD catheter tract beneath the skin.
• These sutures aim to effectively close the potential pathway for CSF migration towards the exit site.

Main Results:

• Case examples demonstrate the efficacy of this surgical approach in successfully halting existing exit-site CSF leaks.
• The technique proved beneficial in managing and resolving CSF leakage complications.

Conclusions:

• The described surgical steps serve as valuable adjuncts in EVD placement procedures.
• This technique should be strongly considered for all high-risk patients requiring EVD insertion to mitigate leak risks.
