Saccular true aneurysm of the ascending aorta 19 years after aortic cannulation: report of a case.
A 61-year-old woman who had undergone surgery for a right ventricular myxoma 19 years earlier was admitted to our hospital for treatment of a saccular aneurysm of the ascending aorta at the site of the previous aortic cannulation. We resected the aneurysm completely and closed it with a polyester patch. Pathologic examination revealed an aortic wall saccular aneurysm, without atherosclerotic changes or bacterial cultures, consisting of elastic fibrous tissue and artificial material. There were inflammatory changes at the top of the aneurysm, with continuity of medial elastic fibrous tissue inside. These pathological findings strongly suggested a true aneurysm with continuity of medial elastic fibrous tissue. We report this extremely unusual case of a saccular true aneurysm at a previous aortic cannulation site.
