摘要

Abstract

Objective

To analyze the short-term outcomes of redo coronary artery bypass grafting (CABG) using on-pump and off-pump CABG techniques.

Methods

From January 2003 to August 2013

non-randomized 80 patients were treated with redo CABG in the Department of Cardiac Surgery

Peking University Third Hospital. Among these patients

40 underwent on-pump CABG technique (redo-ONCAB group) and 40 underwent off-pump CABG technique (redo-OPCAB group). Furthermore

transmyocardial laser revascularization was performed in high-risk patients who were not suitable to conventional grafting. Clinical data of the two groups were recorded and analyzed including operation time

coronary grafts

incomplete revascularization

postoperative ventilation

perioperative stroke

and low output syndrome

etc.

Results

There were no significantly differences in age

gender distribution

incidences of hypertension

stroke

and other clinical characteristics between redo-OPCAB group and redo-ONCAB group (all

0.05)

except for incidences of renal dysfunction and pulmonary disease (all

0.05). The number of grafting vessels in the redo-ONCAB and redo-OPCAB groups was 2.1 ± 0.74 and 1.4 ±0.52 respectively. There was significant difference between the two groups (

=0.0243). Compared with the redo-ONCAB group

there was shorter operation time (

=0.0045)

postoperative ventilation (

=0.0211) and intensive care unit stay (

=0.0400)

as well as fewer use of platelet (

=0.0338) and blood transfusion (

=0.0034) in the redo-OPCAB group. The incidence of incomplete revascularization (

=0.0253) and the use of transmyocardial laser revascularization (

=0.0052) were higher in the redo-OPCAB group than those in the redo-ONCAB group (all

0.05). However

no significant differences were showed for the incidence of the use of intra aortic balloon pump and continuous renal replacement therapy

perioperative stroke

low output syndrome

and in-hospital mortality between the two groups (all

0.05).

Conclusion

Redo CABG is the safety and efficacy surgical procedure

and redo-OPCAB technique with better outcomes is commended especially in high-risk patients.
