Patients with High Hematocrit Undergoing Coronary Artery Bypass Graft Surgery: A Case Report and Literature Review

Abstract

Patients undergoing coronary artery bypass graft (CABG) surgery with elevated hematocrit levels can face unique challenges related to increased blood viscosity, compromised tissue perfusion, and impaired oxygen delivery. This case report presents a 45-year-old male patient with very high hematocrit levels who underwent CABG surgery. Preoperative optimization, intraoperative monitoring, and postoperative management were implemented to mitigate the risks associated with high hematocrit. The patient’s hematocrit, blood gases, and cerebral saturation were continuously monitored during the procedure, demonstrating adequate perfusion. The patient had an uneventful postoperative course and was extubated the same day. A literature review revealed limited evidence regarding the management of high hematocrit patients undergoing cardiac surgery, emphasizing the need for further research. Tailored management strategies, including preoperative hematocrit optimization and individualized antithrombotic therapy, are crucial for optimizing outcomes in this patient population.
