Complications of aortic atherosclerosis: atheroemboli and thromboemboli

Area of Science:

• Cardiovascular Medicine
• Vascular Surgery

Background:

• Severe aortic atherosclerosis significantly increases the risk of stroke and embolic events.
• Established therapies to prevent emboli originating from aortic plaque are lacking.
• Identifying and aggressively managing patients with atherosclerosis or embolic disease risk factors is critical.

Purpose of the Study:

• To review current understanding and management strategies for embolic complications in patients with severe aortic atherosclerosis.
• To highlight the importance of risk factor modification and explore procedural considerations.

Main Methods:

• Review of retrospective data on severe aortic plaque and stroke prevention.
• Analysis of iatrogenic embolization risks during vascular procedures and surgery.
• Evaluation of alternative procedural approaches and prophylactic measures.

Main Results:

• Retrospective data suggest statins may reduce stroke risk in severe aortic plaque patients.
• Aggressive management of blood pressure, glucose, and smoking cessation are important.
• Off-pump coronary artery bypass grafting (CABG) is a viable alternative for selected patients.
• Brachial arterial access may reduce embolic risk during angiography in specific cases.

Conclusions:

• Patients with severe aortic atherosclerosis require aggressive medical management and careful consideration of procedural risks.
• Statins, aspirin, smoking cessation, and control of hypertension and diabetes are key preventive strategies.
• Procedural modifications, such as off-pump CABG and brachial artery access, can mitigate embolic risks.
