Objective: Aneurysm formation of the pulmonary trunk is rare and there is c
ontroversy about optimal treatment for this disease. The aim of this articl
e is to report four patients with pulmonary trunk aneurysm which were manag
ed by surgical repair, Materials and methods: From 1986 to 1997, we perform
ed surgical repair for pulmonary trunk aneurysm in four patients. There was
one male and three female patients with a mean age of 63.3 years (range: 5
4-78 years). Concomitant diseases were cardiac valvular disease in four pat
ients, thoracic aortic dissection in two, atherosclerotic abdominal aortic
aneurysm in two, and coronary artery disease in one. All patients were in N
ew York Hear? Association functional class LII preoperatively. Surgical pro
cedures for the pulmonary trunk aneurysm included Dacron graft replace ment
in two patients and aneurysmorrhaphy in two. Associated procedures were ca
rdiac valvular operation in three patients with four lesions and right vent
ricular outflow tract reconstruction (RVOTR) in one. Results: There were no
operative mortalities and no late deaths with a mean follow-up period of 6
.6 years (range: 2.4-10.0 years). One female patient developed recurrent pu
lmonary trunk aneurysm 9.5 years after aneurysmorrhaphy, and underwent a se
cond operation where Dacron graft replacement of the aneurysm including pul
monary valve replacement was performed successfully. All patients are now l
eading normal lives. Conclusions: Surgical management should be considered
for large aneurysm of the pulmonary trunk regardless of its etiology and un
derlying disease to prevent possible rupture with fatal result if the patie
nt has an acceptably low operative risk. (C) 2000 Elsevier Science B.V. All
