The aim of this paper is to compare the immediate follow-up of
patients (pts) operated upon with and without cardiopulmonary
bypass (CPB) .
We divided 239 pts submitted to CABG in 3 groups (G): G I - OPCAB
with aortic approach (63 pts); G II - OPCAB with no aortic approach
(64 pts); G III CABG with CPB (95 pts). The number of bypass/pt
was 2.17, 1.16 and 3.27 respectively and reoperations, emergency
surgery and pts over 80 years were excluded.
Total morbidity was 7.9%, 12.5% and 13.7%, respectively (p=0.225).
Regarding neurological complications, there were 2 (2.1%) strokes
in G III and none in the other groups (p=0.017). The mortality
rate was : 3.17% in the G I; zero in the G II and 3.16% in the
G III (p=0.472).
In conclusion, in these pts the OPCAB groups presented less neurologic
complications when compared with CPB group and the total morbidity
and mortality rates were not reduced when compared the 3 groups.
