Chronic posttraumatic aneurysm of descending aorta with fistulous communication into pulmonary artery.

Abstract

We report an unusual case of presumed posttraumatic chronic proximal descending aneurysm associated with a fistula into the pulmonary artery. Review of the literature showed that a fistula of the descending aorta into the pulmonary artery is uncommon and that only a few patients have survived. This rare entity is best treated with open repair; however, in patients at high risk an endovascular stent graft is an option.
