Study Design and Patients
An institutional database was used to identify all patients who underwent proximal aortic operations at a single referral aortic center (Duke University Medical Center, Durham, NC) from June 2005 to March 2014. Proximal aortic operations were defined as ascending aortic replacement with or without aortic root replacement, with or without aortic valve repair or replacement, or with or without aortic arch replacement. Patients who underwent reoperations after having undergone an index proximal
Patient Characteristics
From June 1, 2005, to March 15, 2014, 869 patients at our institution underwent proximal aortic operations. Reinterventions occurred in 4.3% of patients (n = 37). Baseline characteristics of all patients at the time of the index proximal aortic operation are reported in Table 1, stratified by whether patients ultimately went on to have a reintervention. Among patients who subsequently required reinterventions, there was a higher frequency of baseline hypertension, history of stroke or transient
Comment
In the current analysis we demonstrate that thoracic aortic surgical reinterventions among patients who undergo proximal aortic operations are uncommon, occurring at a frequency of 4.3% over a 9-year study period. For both patients with an index proximal aneurysm operation or type A dissection repair, the most common indication for surgical reintervention was the metachronous development of an aneurysm of the descending or thoracoabdominal aorta, which occurred at an overall median time of 2.8
