Routine use of PACs for perioperative monitoring with the above protocol during aortic surgery is not beneficial and may be associated with a higher rate of intraoperative complications. Preoperative tune up does not prevent postoperative cardiac, renal, and other complications. Variables such as cardiac risk factors and adenosine thallium scintigraphy may be more important predictors of cardiac events in patients who undergo aortic operations.

Ocular symptoms and findings are poor predictors of CAOD. Amaurosis fugax, Hollenhorst plaques, and venous stasis retinopathy demonstrated moderate predictive value, whereas all other ocular findings demonstrated no predictive value in identifying CAOD.
