Abstract

Background: Off-pump coronary artery bypass grafting surgery (OPCABG) is a minimally invasive technique and is recognized for its good results. We present our experience in performing this technique on a routine basis using Doppler ultrasound during surgery on 33 patients at Military Hospital 175. Objective: To evaluate the results of OPCABG surgery using Doppler ultrasound during surgery at Military Hospital 175. Subjects and methods: Longitudinal observational study on a group of 33 patients undergoing OPCABG surgery using Doppler ultrasound during surgery from May 2022 to March 2023. Results: There were 21 male patients, accounting for 64%. The mean age was 60,7 ± 9.9 years old (44 to 82 years old). The stenosis of the left main coronary artery was found in 8 cases (24,2%) and all patients had 3-vessel disease. The mean bypass was 2,36 per patient. In-hospital mortality was 0%. The intraoperative Doppler ultrasound parameters (PI and Flow) are respectively: LIMA-LAD: 1,7 ± 0,3; 29,2 ± 10,5; RIMA-OM: 2,4 ± 0,5, 19,2 ± 7,2; GSV-OM: 1,5 ± 0,3, 25,3 ± 5,5 GSV-PDA: 1,7 ± 0,2, 37,3 ± 3,5. Ventilation time was 10,4 ± 4,6 hours; postoperative time was 12,5 ± 5,9 days. Conclusion: OPCABG surgery using Doppler ultrasound during surgery is safe and effective.
