3.3 Perioperative and early clinical outcomes
Significantly shorter ICU and hospital stay was observed in the FLS
group, while other parameters were not statistically significant between
the two groups. In per-protocol analysis, only hospital stay was
significantly shorter in the FLS group compared with the conventional
group (Table 3).
No myocardial infarctions, prosthesis endocarditis, respiratory
failures, or deaths were observed in either group. One patient in the
FLS group had mild PVL, whereas 4 patients in the conventional group had
PVL (one mild, 2 moderate, and one severe). However, there was no
significant difference in PVL incidence between the two groups, based on
either in intention-to-treat (P=0.483) or per-protocol analysis
(P=0.609). 2 patients in FLS and 6 patients in conventional groups
experienced cerebrovascular events during perioperation. Although the
number of cerebrovascular events was
far more in the conventional group, there was no statistical difference
between two groups. Cerebrovascular events progressed to permanent
strokes in 2 patients from the conventional group, whereas the other 6
patients had no sequelae.
