Safe sternal reentry in patients with large thoracic aortic pseudoaneurysms.

Sternal reentry for ascending aorta pseudoaneurysm repair presents a formidable challenge because of the risk of aneurysm rupture and hemorrhage. We describe two cases of large pseudoaneurysms at high risk for rupture during sternal reentry in which the chest was safely entered by use of an anterior sternal retraction technique. Several other methods for sternal reentry have been reported; however, the reliability and efficiency of the described technique make it the preferred method for sternal reentry for pseudoaneurysms at our institution.
