Surgical treatment of double aortic arch malformation combined with descending aortic arch dissection in adults: a case series

Background: Double aortic arch (DAA) combined with descending aortic arch dissection (DAAD) in adults is a rare aorta vascular disease. Due to the abnormal anatomy of the double arch and arch vessels, the clinical symptoms and surgical methods differ from those of typical aortic dissection. Methods: : This study was retrospective analysis of a case series involving three patients (mean age, 47.3 years) with DAA combined DAAD underwent total arch replacement or hybrid aortic repair from September 2010 to June 2019. The patients’ demographics, initial symptoms, comorbidities, surgical procedures, and outcomes are summarized. Results: : Total arch replacement plus frozen stent implantation under deep hypothermic circulatory arrest was performed for 2 patients，one of them developed disseminated intravascular coagulation and multiple organ failure postoperatively. Case 3 underwent a hybrid procedure with left subclavian artery revascularization and thoracic endovascular aortic repair. The symptoms of hoarseness and dysphagia were obviously improved during the follow up. Conclusion: In addition to typical sudden chest and back pain, patients with DAA and DAAD may have hoarseness and dysphagia. Based on the development of DAA, total arch replacement or hybrid surgery may be is an optional treatment.
