Abstract
Despite the decrease in the over all incidence of complications after
CABG ,yet the incidence of postoperative strokes remains the same and the
risk is a direct function of the patient’s age ranging from 0.2 % in patients less
than 45 years old and up to 8% in patients above 75 years old, where the
current increase in the mean age of CABG patients highlights the stroke risk.
The causes of perioperative stroke are multifactorial but mainly:
1. Aortic causes:
Due to iatrogenic mobilization of calcified aortic plaques (during
cannulation or cross-clamping ) leading to cerebral embolization.
2. Carotid stenosis:
Which is the only anatomic situation about which the surgeon can
routinely take action to remove the pathology (hence its importance).
3. Other causes:
Air or fat embolism , peripheral vascular disease (PVD), hypothermia ,
hemodynamic fluctuations ,systemic inflammatory response …etc
Cost of perioperative stroke:
Post operative stroke remains a catastrophic and costly complication with
up to 10 fold increase in mortality and 3 fold increase in hospital stay as
compared to non-complicated patients.
