DAVID VERSUS BENTALL – A COMPARISON OF EARLY POSTOPERATIVE COMPLICATIONS

Abstract

The aim of the work: to analyze and compare the early postoperative complications in patients operated due to the presence of aneurysms of the root and ascending aorta and aortic valve pathology by the David and Bentall technique. Materials and Methods. It was a retrospective study. There were 107 patients who were routinely treated surgically at the Heart Institute of the Ministry of Health of Ukraine from 2015 to 2023. Patients were divided into two groups depending on the type of surgical intervention: in group A – David operation was performed, in group B – Bentall operation. All data were collected and compared in preoperative, intraoperative, and postoperative period. Results and Discussion. According to the duration of operations, the indicators are higher in patients of group A. Thus, the total duration of the operation was (291.23±12.67) minutes in group A and (244.418±7.67) min. in group B, respectively (p 0.001). The total duration of artificial blood circulation was (170.28±8.77) minutes in group A and (138.73±6.47) min. in group B, respectively (p 0.003). Aorta clamping time – (122.02±5.92) min. in group A and (95.82±4.79) min. in group B, respectively (p 0.000). Patients of group A had faster extubation. They spent less days in the intensive care unit and in the hospital in general. Among the early postoperative complications, it is important to note a greater proportion of arrhythmias in patients after Bentall operation. The share of acute respiratory failure with repeated reintubation is statistically higher in group B. Other indicators did not differ statistically among patients. The frequency of cell saver use was almost the same in the two groups of patients. The rate of reoperations due to bleeding did not differ statistically and was 3 (5.66 %) for group A and 6 (10.91 %) for group B (p 0.328).
