Surgical treatment of pericarditis in the dialysis patient.

Eighteen patients with pericarditis complicating chronic renal failure who were unresponsive to medical therapy underwent surgical decompression of the pericardium for either pericardial tamponade [16] or constrictive pericarditis [2]. There was one perioperative death and minimal morbidity. Preoperative pericardiocentesis in nine patients afforded only temporary relief in most of the patients and caused a life-threatening pericardial tamponade in one patient. Creation of a pericardial window through a left anterior thoracotomy was the procedure of choice in patients without signs of constrictive pericarditis or posterior loculated effusions and had excellent long-term results. We recommend early surgical treatment of uremic pericarditis in all patients with hemodynamic instability, enlarging pericardial effusion, or effusion that is unresponsive to intensive medical therapy.
