Conclusion: Consideration of the higher residual tumor rate in patients who received non-standard operations,the re-operations were necessary.Contrast-enhanced CT positive predictive value was high for residual tumor and it was important for re-operation.展开更多

We describe reconstruction of an extended root and ascending aorta using our current strategy. Patients and Methods: Between March 2011 and December 2012, 15 (11 men;mean age, 70.1 ± 7.3 years) patients underwent root reconstruction with hemi-arch replacement under hypothermic circulatory arrest with antegrade selective cerebral perfusion. The maximum diameter of the aortic root was 52.5 ± 4.4 mm. The distal ascending aorta just below innominate artery was moderately dilated to 41.7 ± 1.4 mm in diameter. Results: Operative outcomes excluding the diameter of the distal ascending aorta did not significantly differ from those of patients who had undergone root reconstruction under distal ascending aortic clamping during the same period. Postoperative computed tomography confirmed complete resection of the dilated ascending aorta in the patients, and did not develop neurological dysfunction or stroke. Conclusion: Postoperative computed tomography confirmed complete resection of dilated ascending aortae. We considered that complete resection under hypothermic circulatory arrest and selective cerebral perfusion might help to avoid repeated surgery to treat dilation of the distal ascending aorta over the long-term.展开更多

Methods The data of 312 patients (average age 65±9 years) who had CABG operation in Hartford hospital were collected and analyzed. The mean duration follow up after the first CABG was 11.8±4.5 years. A total of 1069 bypass grafts were performed. Among them, 386 were arterial grafts such as internal mammary artery, radial artery and gastroepiploic artery; 682 were venous grafts and 1 Gore-Tex graft. Results The operative mortality was 4.5%. Fifteen patients ( 4.8%) had peri-operative myocardial infarction and 46 patients (15%) had low cardiac output syndrome. Intra-aortic balloon pump (IABP) was used in 131 patients before, during and after operation. One hundred and nineteen patients weaned off IABP and recovered. Conclusion Although the difficulties and risk factors were increased, the results of redo CABG were still good.展开更多
