[Coronary reoperations].

BACKGROUND: We report our experience with 85 patients undergoing a second time CABG in our institution, highlighting surgical techniques and results. METHODS: Eighty five patients underwent a second coronary artery revascularization between 1971 and 2002 at Vilnius University Hospital Santariskiu Clinics. There were 78 men (91.8%); the mean age was 56.5 years (range 40-75). The reason for the second operation was graft failure in 89.4% of the cases. RESULTS: Direct myocardial revascularization was performed in all patient with a mean of 2.4 graft per patient (range 1-4). The internal mammary artery was utilized 17.6%. Hospital mortality was 1.1%. CONCLUSION: Our data suggest that a second - time coronary revascularization can be justified, with gratifying operative success and good results.

[Coronary artery revascularization without cardiopulmonary bypass].

OBJECTIVE: We sought to report our recent experience with off-pump coronary artery revascularization. MATERIAL AND METHODS: Between July 1998 and July 2002, 80 off-pump beating heart operations were performed at Vilnius University Hospital Heart Surgery Clinic, representing 4.05% of all coronary artery revascularization. This cohort of patients was compared with 241 patients operated on with cardiopulmonary by pass. RESULTS: Mean age and preoperative risk factors were comparable for the two groups. On average, 2.02+/-0.86 and 4.09+/-1.09 grafts per patient were completed in the beating and cardiopulmonary bypass groups, respectively. Operation time was shorter in the beating heart group (169+/-41 vs. 215+/-59 minutes). Similarly, the need for transfusion was significantly smaller in the beating heart group (beating heart operations, 10%; cardiopulmonary bypass, 28%; p<0.001). CONCLUSIONS: In majority of patients, off-pump coronary artery revascularization is an acceptable alternative to conventional operations with good results.
