INTRODUCTION: @entity2294 and @entity955 occur commonly after coronary artery surgery. AIM OF THE STUDY: A prospective randomized clinical trial was conducted to evaluate the effects of posterior pericardiotomy on the occurrence of @entity2294 , tamponade, and @entity955 . MATERIAL AND METHODS: The study group consisted of 96 @entity1 (77 male and 19 female) at a mean age of 58.1    9.8 years. The @entity1 were randomly assigned to one of three study groups: @entity1 undergoing posterior pericardiotomy (group I, n = 30), controls (group II, n = 33), and @entity1 with additional posterior pericardial drainage tubes (28 mm) who did not undergo posterior pericardiotomy (group III, n = 33). RESULTS: Postoperative hospitalization (p = 0.03; 11.56    10.64) and reoperation due to tamponade (p = 0.019; 12.1%) were significantly higher in group II. Extensive pericardial effusions were detected in one @entity1 on the first postoperative day (group II, n = 1), in one @entity1 on the fifth postoperative day (group III, n = 1), and in one @entity1 on the 30(th) day after the operation (group III, n = 1). @entity2294 exhibited regression in group I on postoperative day 30 (p = 0.028). A higher rate of postoperative @entity955 was noted in group I, but no significant differences were found between the groups with regard to postoperative @entity955 . CONCLUSIONS: @entity1 who did not undergo posterior pericardiotomy or did not receive posterior chest tubes exhibited @entity2294 , required longer hospitalization, and had to be reoperated due to tamponade. Both posterior pericardiotomy and the use of posterior tubes are effective in the early postoperative period.
