Abstract:
Pulmonary trunk aneurysm is generally associated with congenital cardiac defects, pulmonary hypertension, or infection. Idiopathic pulmonary trunk aneurysm without any associated diseases is a rare lesion and has seldom been reported. Here, we report a case of a 68-year-old woman with idiopathic pulmonary trunk aneurysm. The maximum diameter of the aneurysm was 53 mm while she was 142 cm in height. We successfully performed aneurysmorrhaphy and her postoperative course was uneventful. Aneurysmorrhaphy was an effective technique for idiopathic pulmonary trunk aneurysm without pulmonary hypertention.
