Inoue balloon pericardiotomy for patients with recurrent pericardial effusion.

The results and follow-up data for 11 patients with recurrent effusion due to various etiologies who underwent balloon pericardiotomy with the Inoue balloon catheter between May 1992 and July 1994 are described. Inoue balloon pericardiotomy was successful in 10 patients (91%), who remained free of pericardial effusion at a mean follow-up duration of 4.2 months. All patients tolerated the procedure well with minimal discomfort and with no complications. Despite good symptomatic relief, 9 patients (82%) eventually succumbed to disease dissemination, with a mean survival time of 1.4 months. It is concluded that Inoue balloon pericardiotomy is a safe and useful alternative to surgical pericardial windowing for the symptomatic treatment of recurrent pericardial effusion.
