Mid-term results of coronary artery bypass surgery assessment by multisliced CT scan at Dong Nai General Hospital

Abstract

Introduction: Coronary artery bypass grafting is a major surgery that uses different grafts to bypass atherosclerotic lesions causing stenosis or occlusion of coronary arteries. There are two types of techniques: coronary artery bypass grafting with cardiac arrest and without cardiac arrest. MSCT 256 is a good means of assessing graft patency.

Methods: Case series report, retrospective of patients undergoing coronary artery bypass surgery at Dong Nai general hospital. Patients who meet the selection criteria will have an MSCT 256 scan with contrast to evaluate the level of graft patency.

Results: 40 patients were included in the study from May 2021 to August 2024. Average age is 62 years old, men account for 75% of patients. The average number of anastomoses was 3.05, the average surgery time was 243 minutes. The early mortality rate is 2.5%, early complications include acute myocardial infarction (2.5%), reoperation due to bleeding (2.5%), sternum infection (5%), and pneumonia requiring mechanical ventilation > 24 hours. hours (10%). The medium-term mortality rate was 5.1%, with cardiovascular mortality. The coronary graft patency was good, there was 1 case of unclear image of the vein - obtuse artery - posterior descending artery bypass.

Conclusion: Coronary artery bypass surgery at Dong Nai General Hospital has good mid-term results, showing the effectiveness of the program to transfer open heart surgery techniques from Cho Ray Hospital to Dong Nai General Hospital.  Implementing this technique helps reduce the load on central hospitals and enhances the reputation of local teams. Coronary CT Scan helped assessing the patency of CABG in stable postoperative patients.
