Abstract:
A 77-year-old woman with a previous history of median sternotomy and collagen disease, presented with chief complaints of resting dyspnea as a result of recurrent pericardial effusions or restrictive ventilatory impairment. She experienced significant symptom amelioration after undergoing pericardioperitoneal fenestration. We weighed the positive against the negative of various pericardial effusion drainage methods in this study. This operative procedure is not innovative, but favorable because it can be carried out conveniently and safely, enabling early rehabilitation without appreciable postoperative complications.
