Successful use of thoracoscopic pericardiectomy in elderly patients with massive pericardial effusion caused by uremic pericarditis.

摘要

We report the use of thoracoscopic pericardiectomy to treat two elderly patients with massive pericardial effusion caused by uremic pericarditis. A 79-year-old man, admitted to our hospital complaining of dyspnea, was diagnosed with end-stage renal failure and began maintenance hemodialysis. Although intensive hemodialysis was performed, the patient could not remain on hemodialysis because of severe hypotension during the procedure. Echocardiography revealed massive pericardial effusion and severe hypokinesis of the left ventricular wall. Pericardiocentesis was performed first, without success, followed by thoracoscopic pericardiectomy under general anesthesia. One month after the pericardiectomy, episodes of hypotension during hemodialysis improved, and dyspnea diminished. Echocardiography showed no pericardial effusion and improvement of left ventricular wall motion. Pericarditis is a fatal complication in patients with end-stage renal failure and patients on maintenance hemodialysis. The second patient received the same procedure with a similar improvement of clinical symptoms. These cases suggest that thoracoscopic pericardiectomy is a safe and effective treatment of pericardial effusion caused by uremic pericarditis in elderly patients on hemodialysis.
