Abstract
BACKGROUND
The perioperative outcomes following off-pump multi-vessel minimally invasive surgery (MICS) coronary artery bypass grafting (CABG) via a single left intercostal space incision has not been well evaluated.
METHOD
From July 2019 to January 2022, a total of 444 patients with multi-vessel coronary artery disease (CAD) were enrolled and divided into MICS (n = 179) and sternotomy CABG (n = 265). Perioperative outcomes were compared between these two groups, including intraoperative blood loss, postoperative first 24 h drainage, ventilation duration, length of stay (LOS) in ICU and total LOS in hospital. Intraoperative blood flow of graft vessels were measured by transit-time flow measurement after vascular anastomosis and mean flow (MF) and pulsatile index (PI) were compared.
RESULTS
There were no significant differences in preoperative profiles between these two groups except younger and lower proportion of female in MICS. No significant difference in the number of graft vessels was observed between MICS (3.18 ± 0.74) and sternotomy CABG (3.28 ± 0.86). Compared to sternotomy CABG, patients with MICS showed longer operation duration [(4.33 ± 0.86) h versus (5.10 ± 1.09) h], fewer intraoperative blood loss [700 (600, 900) mL versus 500 (200, 700) mL], fewer postoperative first 24 h drainage [400 (250, 500) mL versus 300 (200, 400) mL], shorter postoperative ventilation duration [16.5 (12.5, 19.0) h versus 15.0 (12.0, 17.0) h], LOS in ICU [20.0 (16.0, 23.0) h versus 18.0 (15.0, 20.0) h] and total LOS in hospital [(14.5 ± 3.9) d versus (12.6 ± 2.7) d] (all p < .001). MI and PI of graft vessels were similar and no significant differences in major perioperative complications and mortality were observed between MICS and sternotomy CABG (all p > .05).
CONCLUSION
Off-pump multi-vessel MICS may be an alternative treatment for patients with multi-vessel CAD with better perioperative outcomes than sternotomy CABG.
