title: Effects of prophylactic indomethacin treatment on postoperative pericardial effusion after aortic surgery.
abstract: OBJECTIVE
  This prospective, randomized study assessed the prophylactic effects of indomethacin treatment on pericardial effusion after aortic surgery.
  
  
  METHODS
  Eighty-five patients were found eligible to participate in this double-blind study. Patients were assigned to a control group receiving oral placebo or to an indomethacin group receiving 25 mg oral indomethacin 3 times daily for 7 days preoperatively. After aortic surgery, patients were followed up clinically and evaluated for pericardial effusion with transthoracic echocardiography on the first and seventh postoperative days during hospitalization and at the second and sixth weeks after discharge.
  
  
  RESULTS
  The demographic and the operative data were similar between groups. The surgical interventions included Bentall procedure in 63 patients, valve-sparing procedures in 7 patients, and supracoronary ascending aorta replacement in 15 patients. Hemiarch replacement was performed in 16 patients. No patient in either group had pericardial effusion after the first postoperative day. At the end of the first week, however, 2 patients had pericardial effusion, at the end of the second week after discharge, 3 patients had pericardial effusion, and at the end of the sixth week after discharge, 4 patients had PEs. One of the patients who had PE at the end of the sixth week received indomethacin; the others were all in the control group, a significant difference (P=.019). Five patients underwent transthoracic echocardiographically guided pericardiocentesis; 4 underwent surgical pericardiocentesis.
  
  
  CONCLUSIONS
  Indomethacin may have beneficial effects on the outcomes and incidence of postoperative pericardial effusion after aortic surgery.
