[Perioperative strokes in cardiac surgery]

Area of Science:

• Cardiology
• Neurology
• Surgical Sciences

Background:

• Perioperative stroke occurs in up to 10% of cardiovascular surgery patients, particularly after coronary artery bypass grafting and valve replacement.
• Risk factors include embolism from atherosclerotic plaque, hypotension, arrhythmias, and hypercoagulation.
• Minimizing aortic manipulation and optimizing intraoperative blood pressure and saturation are key preventive strategies.

Purpose of the Study:

• To review the incidence, risk factors, and management strategies for perioperative stroke in cardiovascular surgery.
• To highlight the importance of preoperative assessment and intraoperative monitoring in stroke risk reduction.
• To emphasize the role of timely diagnosis and mechanical thrombectomy in managing perioperative stroke.

Main Methods:

• Review of existing literature on perioperative stroke in cardiovascular surgery.
• Analysis of risk factors, including patient-specific and surgical variables.
• Discussion of current preventive measures and treatment options, including mechanical thrombectomy.

Main Results:

• Perioperative stroke incidence can be significant, especially following major cardiac procedures.
• Preoperative patient assessment and meticulous surgical technique, including limited aortic manipulation, can mitigate stroke risk.
• Early identification of stroke and prompt reperfusion therapy, primarily mechanical thrombectomy, are critical for patient outcomes.

Conclusions:

• Proactive risk factor management and optimized surgical practices are essential for reducing perioperative stroke in cardiac surgery.
• Timely diagnosis and intervention, such as mechanical thrombectomy, offer the primary therapeutic approach for perioperative stroke.
• Further research into advanced preventive and therapeutic strategies is warranted to improve patient safety in cardiovascular surgery.
