Surgical management of right aortic arch with tailored surgical approach.
OBJECTIVE
Right-sided aortic arch is a rare congenital anomaly for which different surgical approaches have been reported. This study reviewed our experience with several techniques.


METHODS
We retrospectively reviewed 17 patients undergoing right-sided arch repair at the Cleveland Clinic from 2001 to 2010. Computed tomographic angiograms of the aorta and its branches were reviewed and correlated with patient presentation and surgical approach.


RESULTS
Fourteen patients had type II right aortic arch with aberrant left subclavian artery. Fifteen patients presented with obstructive symptoms. Surgical approach included right thoracotomy (11 patients), left thoracotomy (two patients), full sternotomy (one patient), and hybrid repair (three patients). Cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest was used in 11 patients, and two patients had partial CPB. Left subclavian artery bypass was performed in seven patients. Median duration of intubation was 1.9 days. Average length of intensive care unit stay was three days and average hospital stay 11 days. Postoperative outcomes included respiratory failure (one patient), renal failure (one patient), bloodstream infection (two patients), and death (one patient). No patient had stroke or paraplegia. In-hospital death occurred in one patient, and all survivors were alive and asymptomatic for a mean of 38 months.


CONCLUSIONS
The surgical treatment for right-sided aortic arch can be performed with excellent perioperative outcomes when tailored to patient presentation and anatomic configuration. Patients with obstructive symptoms benefit from open or hybrid surgical treatment, with immediate relief of compression. Patients with aneurysmal dilatation without compression symptoms can be managed with open, endovascular, or hybrid surgical intervention.
