Major (cardiovascular) surgery is frequently associated with cerebral dysfunction postoperatively. Major surgical procedures account for substantial systemic inflammatory activation. Interestingly, animal models have shown that surgery rather than anaesthetics trigger a neurocognitive decline. An increase of pro-inflammatory cytokines and activation of immune cells mediate this post operative cognitive decline. There is growing support that systemic inflammation can activate the innate immune system of the brain leading to inflammation in the brain ('neuroinflammation'). This neuroinflammation is suggested to play a pivotal role in postoperative delirium and postoperative cognitive decline due to surgery-related systemic inflammation. However little evidence is available on the extend of the neuroinflammation and which biochemical pathways are dysregulated in the brain after surgery. Thoracic aortic surgery offers the unique opportunity to study the trajectory of protein expression in CSF prior to and after surgery in a non-invasive matter. It is standard of care that an external lumbar drain (ELD) is placed the day prior to surgery and this ELD will remain in place during three postoperative days. To advance the understanding of the impact of major surgery to the brain, the investigators wish to study the trajectory of protein expression prior to and after thoracic aortic surgery.
