PREOPERATIVE DEPOSITION OF AUTO BLOOD IN THE DEPARTMENT OF VASCULAR SURGERY FOR PATIENTS WITH CONCOMITANT TYPE 2 DIABETES MELLITUS

Introduction. The increasing number of complications with blood transfusions has led to an increased risk of mortality and the need for complex, expensive, long-term treatment. Auto blood is an alternative method for managing intraoperative blood loss, potentially reducing these risks. Preoperative auto-blood deposition minimizes the need for allogeneic blood transfusions in various surgical procedures. Studies have shown mixed results regarding its efficacy and safety. The aim of the study: To evaluate the benefits of preoperative auto-blood collection followed by intraoperative infusion for patients diagnosed with abdominal aortic aneurysms and T2DM, especially when compared to alternative methods of blood loss management. Materials and methods: 341 case histories of patients aged 56 to 73 years were carefully analyzed, with a distribution of 67 women and 274 men. The treatment was performed in the Department of Vascular Surgery of the Lviv Regional Clinical Hospital for ten years, from 2014 to 2024. Results. A retrospective analysis showed that successful surgical outcomes and postoperative recovery were strongly associated with proper blood loss management during surgery. Patients who underwent preoperative auto-blood collection did not have problems related to blood transfusions, unlike those who received donated blood. Conclusions. Using auto blood significantly reduces the likelihood of perioperative complications in patients with type 2 diabetes mellitus. This approach demonstrates a significant advantage over the use of allogeneic transfusions for patients undergoing surgery for uncomplicated abdominal aortic aneurysms.
