Peripheral Cannulation vs. Conventional Methods in Redo Cardiac Surgery: A Single-Center Experience

Objectives: This study aims to compare the outcomes of peripheral cannulation (PC) and central cannulation (CC) techniques in redo cardiac surgeries. Materials and Methods: A retrospective analysis was conducted on 104 patients who underwent redo cardiac surgery between January 2010 and January 2023. Patients were divided into two groups based on the cannulation technique used: PC (n=56) and CC (n=48). Preoperative, intraoperative, and postoperative parameters were collected and analyzed. Results: Significant differences were observed in cardiopulmonary bypass time (127.1±13.6 minutes for PC vs. 120.1±15.4 minutes for CC, p=0.021) and total operation time (295.7±40.4 minutes for PC vs. 249.9±39.5 minutes for CC, p<0.001). The incidence of procedure-related injuries was significantly lower in the PC group (5.4% vs. 31.2%, p=0.036). Overall complications were also significantly lower in the PC group (10.7% vs. 35.4%, p<0.001). Postoperative ventilation duration was shorter in the PC group (5.4±1.1 hours vs. 6.0±1.5 hours, p=0.036). Hemoglobin, C-reactive protein, and ejection fraction levels pre- and postoperatively showed no significant differences between the groups. These findings suggest that PC may offer a safer alternative with fewer complications in redo cardiac surgeries. Conclusion: PC may offer a safer alternative with fewer complications in redo cardiac surgeries compared to CC. These findings suggest the potential benefits of using PC in reducing procedure-related injuries and overall complications.
