Surgery-related neurological impairment can be distressing for patients and their families. Importantly, unlike other organs like the kidney (dialysis machine, transplant), heart (ventricular assist device, transplant), liver (transplant), lungs (extracorporeal membrane oxygenation, transplant), or skeletal system (extracorporeal membrane oxygenation, transplant), there is neither a temporary nor sustainable alternative to native neurological function (artificial joints). It might be claimed that despite the significance of the central and peripheral nervous systems, the field of anaesthesiology has routinely disregarded neural function in the lead-up to surgery.

A significant cause of patient morbidity and mortality following heart surgery is brain damage. Because more senior patients are being treated, the association between the risk of brain injury and advanced age predicts that these complications will occur more frequently.

The frequency of peri-operative stroke, a fatal complication, varies significantly depending on the type of operation. The frequency of stroke is less than 1% for the majority of non-cardiac, non-neurological, and non-major vascular procedures.   The frequency of major vascular and cardiac surgery is substantially higher. In a large series, patients who underwent multiple cardiac valve operations had the highest stroke rate (9.7%), followed by patients who underwent isolated mitral valve surgery (8.8%), combined coronary artery bypass graft (CABG) with valve surgery (7.4%), isolated aortic valve surgery (4.8%), and isolated CABG surgery (3.8%). 5. Given the high-risk patient groups receiving transcatheter aortic valve replacement (TAVR), the occurrence of stroke following this operation has attracted particular attention. following the treatment.

Due to the fact that delirium frequently appears when patients are no longer directly under the care of an anaesthetist, they have historically not given it much attention. Delirium upsets patients and their families and is a challenging issue for doctors because there are no cures to lessen its occurrence or shorten its length. Numerous pathogenic pathways, such as neurotransmitter imbalance, neuroinflammation, endothelial dysfunction, poor oxidative metabolism, and altered availability of big neutral amino acids, have been linked to delirium, which makes it challenging to prevent or cure.

Seizures, perioperative delirium, and postoperative cognitive dysfunction (POCD) are additional neurological side effects following surgery. Focused or generalised seizures might present as behavioural abnormalities, altered levels of consciousness, or tonic or clonic motor activity, among other indications.

Postoperative cognitive dysfunction describes declines from baseline in a range of cognitive abilities, including verbal fluency, executive function, memory, attention, focus, and/or visual spatial ability. The psychometric testing battery used, patient age, education level, kind of procedure, timing of the testing, and the diagnosis of cognitive decline are only a few of the variables that affect POCD frequency. Comparison of the data between institutions is complicated by the substantial variation in these characteristics between research. When examined 1 month following cardiac surgery, 10% to 30% of patients generally report having POCD. The risk for POCD following TAVR operations has not been sufficiently studied.
