Objective: The aim of this study is to present experience with 10 patients with symptomatic aberrant subclavian artery (ASA) and aneurysm of ASA who underwent surgical treatment. Methods: From 2008 to 2011 10 patients with symptomatic aberrant subclavian artery (mean age 60 years [range 24-90 years]) were studied. Symptoms were dysphagia (n = 7), dyspnea (n = 4), acute chest pain (n = 1), respiratory distress syndrome (n = 1), superior cava syndrome, and shock (n = 1). Six patients had aneurysm formation of the ASA (mean diameter of 7.1 cm [range 3.0-12.4 cm]; rupture [n = 1], dissection [n = 1]). All data were analyzed retrospectively. Results: Treatment was performed as a hybrid procedure in eight patients. This included thoracic endoluminal graft exclusion with revascularization of the ASA, a pure endovascular procedure with two occluders in one patient, and an open procedure in one patient with ligation of the aberrant artery through a thoracotomy. Three patients died during the early postoperative period owing to pulmonary complications. All three suffered from a symptomatic aneurysm, and two were treated as an emergency procedure. Median follow-up was 20 months (range 12-49 months). Conclusion: A symptomatic ASA and its associated aneurysmal formation should be excluded after diagnosis. In most cases, a hybrid procedure consisting of thoracic endografting and revascularization of the ASA is feasible.
