摘要
Introduction: Constrictive pericarditis is a disease caused by a chronic inflammatory process, which is characterized by the pericardium's loss of flexibility, inhibiting the function of the heart, ultimately causing heart failure. The only definitive therapy is surgical. Total pericardiectomy, which is the most common surgical approach, is a lengthy pro-cedure with up to 18% operative risk, and it often requires the use of cardiopulmonary bypass. Objective: The evaluation of the effectiveness, results and possible advantages of a surgical technique, "turtle cage" pericardiectomy, which is described in the literature, although rarely used, mainly in addition to conventional peri-cardiectomy. Method: Between 2008 and 2021, we performed 33 "turtle cage" procedures on patients with constrictive pericarditis in our Institute. We compared the results of the 30-day postoperative period with internationally published data from multiple sources. Results: Based on intraoperative findings, the procedure was successful in all cases, there were no instances when the use of cardiopulmonary bypass was required (0%). During the 33 procedures, we lost 1 patient (3%), reoperation was necessary for postoperative bleeding in 1 case (3%), and postoperative dialysis was necessary in 4 cases (12.1%). These results are comparable to those published by high-volume centres, and significantly better than those of one of the European centres published. Conclusion: The "turtle cage" pericardiectomy, as performed in our Institute, is suitable for the treatment of constrictive pericarditis on its own. With its use, we were able to minimize the use of cardiopulmonary bypass and the operative risk. Our results with this technique are comparable to those of the high-volume, highly experienced centres.
