RESUMO
Adequate myocardial protection is crucial for a successful cardiac surgery. In type A aortic dissection, standard methods of delivery of cardioplegic solution may not be adequately effective. Ineffectiveness may happen due to both features of the anatomy of the dissection and to peculiarities of the delivery method itself. We present a new method of delivering a cardioplegic solution using a Foley catheter through the orifice of the brachiocephalic trunk or the left common carotid artery.
RESUMO
BACKGROUND: The method of coronary-coronary bypass grafting was described in 1987 but has not been widely used, and there are only a few studies that report good short-term and mid-term results as well as some individual cases of long-term follow-up. In our medical institution, we carried out an analysis of the long-term results of coronary-coronary bypass grafting, which are presented in this study. METHODS: This was a retrospective single-center study on 95 patients who underwent coronary-coronary bypass grafting as a supplement to the standard coronary bypass grafting procedure. All patients underwent angiographic assessment of the coronary bypass grafts during the long-term follow-up period. The observation period was up to 123 months. Angiographic assessment of 109 coronary-coronary grafts was carried out. RESULTS: Twelve (7.6%) arterial and 11 (19.3%) venous conduits were found to be occluded, and 8 (10.3%) arterial and 10 (31.3%) venous coronary-coronary grafts were occluded during the observation period. CONCLUSION: Arterial coronary-coronary artery bypass grafting represents an alternative technique that allows complete myocardial revascularization.
