ABSTRACT
Objective: To present our experience and demonstrate that right thoracotomy in patients with previous sternotomy is and option that may decrease morbidity and mortality in cardiosurgical reinterventions. Place: Third-level attention hospital. Design: Study of cases and controls. Statistical analysis: Pearson’s chi-square test. Material and methods: It was reviewed the cases of reinterventions for mitral valve surgery performed during the period going from January 1st 1997 and December 31st 2000 on patients who had been subjected to right thoracotomy and they were compared with a similar group that had been operated using sternotomy. Surgical time, associated morbidity and mortality were compared. Results: Forty patients having similar demographic characteristic were operated. Ten of then were operated through right thoracotomy, while 30 patients were operated by means of median sternotomy. The survival was of 90% in those patients that were subjected to right thoracotomy and 70% for the patients of the sternotomy. The time of pulmonary derivation was of 94.8 minutes in the right thoracotomy, against 121.4 minutes when considering the sternotomy. The re-exploration by post-operative bleeding was of 0% for the thoracotomy group, and it was of 13% for the sternotomy (p ‹ 0.01). The blood transfusion was of 5.3 units for the thoracotomy group, while it was of 11.4 units for the sternotomy group (p ‹ 0.05). The 12-years follow-up period up to 12 years in the group of patients who had been subjected to thoracotomy did not show any difference that could be attributed to the surgical approach.Conclusion: Right thoracotomy is a safe surgical option and it also offers less morbidity and mortality in those cases where there is a background of one or two previous sternotomies.REFERENCES
