Minimally invasive direct coronary artery bypass grafting: Report of 33 cases / 中国微创外科杂志

ABSTRACT

Objective To discuss the feasibility and safety of minimally invasive direct coronary artery bypass grafting (MIDCABG). Methods A total of 33 patients underwent small incision, off-pump, single-vessel direct coronary artery bypass grafting in this hospital from March 2001 to September 2003. Left anterior small thoracotomy was adopted in 14 patients, whereas partial midline sternotomy was conducted in 19 patients. The left internal mammary artery was anastomosed to the anterior descending artery in 31 patients, construction of the aorta root-anterior descending artery anastomosis using the great saphenous vein was carried out in 1 patient, and the right gastroepiploic artery was anastomosed to the posterior descending artery in 1 patient. Results The operative mortality was a zero. The intraoperative blood loss was 163?120 ml, and the postoperative drainage, 193?169 ml. The assisted respiration time after operation was 6 4?5 5 hours and the duration in ICU was 17 8?4 4 hours. Follow-up for 14 7?7 4 months found no deaths. Conclusions MIDCABG is a safe and reliable procedure, offering minimal invasion, less blood loss and fewer complications.
