Answer

If an invasive radiologic procedure is necessary, the risk of inducing cholesterol embolism must be considered. If the patient is at high risk, with known or suspected severe aortic atherosclerosis or aortic aneurysm, the Judkins (ie, brachial) approach or a radial artery approach may be used for introducing the catheter into the aorta. However, some investigators found that the approach made no difference, which led them to suspect the ascending aorta as a major source of atheroemboli.

Gentle handling of the severely diseased aorta during cardiac or aortic surgery can reduce the risk of cholesterol embolism. Careful clamping techniques and careful selection of aortotomy sites may minimize disruption of the atherosclerotic plaque.
