[Surgical treatment of constrictive pericarditis].
Since 1957, 30 patients with constrictive pericarditis have been treated surgically in Kyushu University Hospital. The surgical approaches were the left anterolateral thoracotomy in 17 patients (group I); the median sternotomy without cardiopulmonary bypass (CPB) in 6 patients (group II); and the median sternotomy with CPB in 7 patients (group III). The hospital mortality was 3.3 percent. The mean postoperative follow-up period was 11.7 years (longest 30 years). The actuarial survival rate at 5 years postoperatively was 88% in total cases (100% in group I, 82% in group II and 52% in group III), 88% at 10 years, 75% at 15 years and 67% at 20 years. Several patients in group III, who underwent complete pericardiectomy using CPB showed severe congestive heart failure and arrhythmia postoperatively. The comparative study between an poor result group (patients who died within 10 years post-operatively) and a good result group (patients who survived more than 10 years postoperatively revealed that preoperative hepatomegaly, atrial fibrillation and the interval between the onset of symptoms and the pericardiectomy influenced the survival rate significantly. These results suggested that pericardiectomy using CPB was a safe method for removing the calcified pericardium in the patient with severe constrictive pericarditis. However, a careful long term follow-up was necessary for the patient with severe myocardial damage even though the complete pericardiectomy was performed.
