[Atheromatous aorta: clinical pitfall in cardiovascular surgery].

Research output: Contribution to journalArticlepeer-review


A highly atheromatous aorta has been reported to bring about devastating complications such as endorgan ischemia with or without aortic manipulation. One of the complications has been perioperative stroke known that almost the halves suffered have been dead even in recent era. The other of the devastating complications has been called cholesterol crystal embolization or blue toe syndrome, meaning scattered embolization by small cholesterol crystals towards splanchnic organs or lower extremities respectively, which has also known to be critical. Nowadays, new devices have encouraged cardiovascular clinician to have a plan for a safe cardiovascular intervention including aortic manipulation even with highly atheromatous aorta. Before the manipulation, modern powerful modalities such as transesophageal echocardiography, epiaortic ultrasonography and computed tomography (CT), have already become common based on many evidences. During operation, evolving techniques and technologies such as off-pump coronary artery bypass grafting (OPCAB) and axillary artery cannulation both of which are aorta non-touch techniques, which are technically demanding, has proved to reduce perioperative stroke recently even though severe complications still occur in lower percentages.
