[The spinal catheter in aortic surgery : Implications for anesthesia]

Area of Science:

• Neurosurgery
• Cardiovascular Surgery
• Neurology

Background:

• Aortic surgeries carry a risk of spinal cord ischemia, potentially leading to paraplegia.
• Spinal cord ischemia can result from aortic cross-clamping or overstenting of critical arteries.
• Current prophylactic and treatment methods for spinal cord ischemia include spinal catheter use.

Purpose of the Study:

• To evaluate the efficacy and risks associated with spinal catheter use in preventing and treating spinal cord ischemia during aortic surgery.
• To highlight the importance of a thorough risk-benefit assessment for spinal catheter procedures.
• To emphasize the need for adequate training and adherence to parameters for safe perioperative handling.

Main Methods:

• Review of existing literature on spinal catheter use in aortic surgery.
• Analysis of complication rates and types associated with spinal catheters.
• Discussion of clinical presentation differences between catheter-associated complications and ischemic spinal cord injury.

Main Results:

• Spinal catheters are effective in regulating cerebrospinal fluid pressure for spinal cord ischemia prophylaxis and treatment.
• Spinal catheters have a high complication rate, including cerebrospinal fluid leakage, headaches, infections, intracranial bleeding, meningitis, and neuraxial hematomas.
• Complications can manifest with a significant latent period post-procedure.

Conclusions:

• Detailed risk-benefit assessment is mandatory before spinal catheter use.
• Adequate personnel training and strict adherence to drainage parameters are critical for enhancing procedural safety.
• Clinical vigilance is necessary as catheter-associated complications can mimic ischemic spinal cord injury.
