Abstract

Objective: Since 2018, in our institution, we adopted computed tomography (CT) of the chest as a routine pre-operative before CABG. We aimed to determine its impact on the rate of peri-operative CVA and surgical approach.

Method: We retrospectively analyzed the data of 548 patients who underwent isolated CABG at the Townsville University Hospital, between 2015 and 2019. The data was obtained from a prospectively maintained regional registry. Two cohorts were formulated based on whether they had a CT chest as part of their preoperative work-up.

Results: The total number of peri-operative strokes observer were four (0.77%), three (1.33%) in the Pre-op CT cohort and one (0.31%) in the No Pre-op CT cohort (p=0.311). The difference in the mortality rate between the group is statistically insignificant (Pre-op CT: 5 (2.23%) vs No Pre-op CT: 3 (0.93%) p=0.283). The three patients from the pre-op CT group who developed peri-operative strokes had severe calcification of the aortic arch and/or ascending aorta. The surgical approach was modified in 26 patients due to the findings of the pre-op CT. Those changes were composed of On-Pump beating heart CABG (14 patients) and Off-pump CABG with or without partial Cross-clamp or the aorta (12 patients).

Conclusion: Overall, this study reinforces the finding of current literature, that pre-op CT scan should be performed in high-risk patients. The findings of the pre-op CT scans influenced dramatically the surgical approach. CT scans are a simple tool that allows surgeons to better plan a surgical strategy for an individual patient.
