ObjectiveOpen surgical reconstruction for supra-aortic trunk occlusive disease persists despite advances in endovascular therapy. Although extrathoracic reconstructions developed as a safer alternative to transthoracic reconstructions, contemporary national data evaluating relative rates of operative outcomes are lacking.MethodsWith use of the National Surgical Quality Improvement Program (2005-2011), patients who underwent transthoracic or extrathoracic reconstruction were evaluated. Patients with nonocclusive indications were excluded. The primary outcome was a composite end point of stroke/myocardial infarction (MI)/death. Secondary outcomes were 30-day postoperative complications. Univariate and multivariable regression analyses were performed.ResultsOverall, 83 patients (10.7%) underwent transthoracic reconstructions and 692 patients (89.3%) underwent extrathoracic reconstructions. Vascular surgeons performed most transthoracic (96%) and extrathoracic (97%) reconstructions. The most common extrathoracic reconstructions were carotid-subclavian bypass (68%), carotid-carotid bypass (14%), and subclavian transposition (7%). Less commonly, axillary-axillary bypass (6%), subclavian-axillary bypass (2%), subclavian-subclavian bypass (1%), and carotid transposition (1%) were performed. At the time of operation, 10% (transthoracic reconstructions) and 8% (extrathoracic reconstructions) of patients had a concurrent carotid endarterectomy (P < .60). Analysis of more than 20 characteristics showed that the groups did not differ significantly. The two groups had similar rates of postoperative stroke (1.2% in the transthoracic reconstruction group vs 2.2% in the extrathoracic reconstruction group; P > .99), MI (0% vs 1.3%; P = .61), death (2.4% vs 1.3%; P = .33), and stroke/MI/death (3.6% vs 3.8%; P > .99). Transthoracic reconstruction patients had longer hospital stays (6.3 days vs 4.0 days; P < .0002), received more transfusions (8.4% vs 2.5%; P < .0096), and had higher rates of postoperative sepsis (3.6% vs 0.3%; P < .01) and venous thromboembolic complications (3.6% vs 0.4%; P < .02). After adjustment for other factors, including surgical approach, stroke/MI/death was significantly associated with postoperative pneumonia (odds ratio [OR], 26.0; 95% confidence interval [CI], 6.29-108.28; P < .0001), postoperative ventilator dependence (OR, 12.45; 95% CI, 2.74-56.48; P = .001), and postoperative return to the operating room (OR, 4.75; 95% CI, 1.67-13.54; P = .004).ConclusionsAt U.S. hospitals, extrathoracic reconstruction is the more common reconstruction for supra-aortic trunk occlusive disease. Both approaches carry acceptably low rates of death, MI, and stroke. Transthoracic reconstruction results in more resource utilization because of its postoperative complications and greater complexity.Copyright © 2014 Society for Vascular Surgery.
