Subxiphoid partial pericardiectomy with or without sclerosant instillation in the treatment of symptomatic pericardial effusions in patients with malignancy.

Twenty-two patients with malignant pericardial effusions were treated with subxiphoid partial pericardiectomy between 1984 and 1989. Thirteen patients also had a sclerosing agent instilled intrapericardially. Tamponade was relieved by pericardiocentesis before administration of general anesthesia. In 18 patients (82%), the effusions were controlled for longer than 30 days, and two patients died before 30 days without effusion. There were two recurrences at 1.5 and 7 months. There was one death due to hemorrhage from a laceration in a heavily infiltrated pericardium, and one patient had persistent dyspnea after the procedure. Complications included transient atrial arrhythmias (two patients), chest pain after sclerosant instillation (three patients), and fever greater than 37.5 degrees C after sclerosant (five patients). The survival range was 0.1 to 18 months (median, 5 months). Subxiphoid partial pericardiectomy with or without intrapericardial sclerosant is a safe and efficacious treatment for malignant pericardial effusions.
