| We herein review the early results
of minimally invasive coronary artery bypass (MIDCAB). From April
1994 to November 1998, 23 patients underwent MIDCAB, and 12 patients
underwent coronary artery bypass grafting with cardiopulmonary
bypass (CABG). We compared and analyzed the findings of these
two groups. Regarding preoperative factors, the MIDCAB group
included elderly patients, while the CABG group consisted of
younger patients. However, the frequency of hemodialysis, respiratory
disorders and cerebral vascular accidents did not differ significantly
between the 2 groups. Regarding perioperative factors, the MIDCAB
group needed a shorter operation time, and also had a lower bleeding
volume, and a low incidence of blood transfusion. Regarding the
postoperative course, the MIDCAB group needed a shorter artificial
respiration time, and a shorter postoperative hospital stay,
and no mortality was observed. The graft patency of the MIDCAB
group was lower (88%) than the CABG group (100%). However, the
graft patency of the MIDCAB group reached 94% after we used a
stabilizer in the operation. In conclusion, the operation results
of the MIDCAB group were comparatively better than those of the
CABG group. Thanks to recent technological advances, the results
of MIDCAB continue to improve. Though MIDCAB remains an invaluable
operative modality for the treatment of one-vessel disease, surgeons
must be careful to select appropriate candidates for this operative
method. Jpn. J. Cardiovasc. Surg. 29: 309-314 (2000) |
