OBJECTIVES Indications and techniques of repair for symptomatic or aneurysmal aberrant subclavian arteries (ASA) are controversial. This study analyses presentation, treatment and outcome of patients with symptomatic and/or aneurysmal ASA. METHODS Retrospective analysis of consecutive adult patients undergoing symptomatic and/or aneurysmal ASA repair between January 2000 and June 2016. RESULTS Of 12 patients (4 females) with a median age of 66 years (range 24–75), 10 had right ASA and 2 had left ASA originating from a right aortic arch. Six patients (50%) had Kommerell’s diverticulum and 6 patients had aneurysmal dilatation of the ASA itself. Six patients presented with symptoms (dysphagia n = 4, chest pain n = 1, recurrent aspiration n = 1). Nine patients (75%) were treated by open ASA resection/ligation with or without aortic repair. Three patients (25%) underwent hybrid repair using thoracic endovascular aortic repair to exclude the aberrant artery. ASA revascularization was achieved by subclavian–carotid transposition (n = 7), carotid–subclavian bypass (n = 1), aorto-subclavian bypass (n = 3) or reimplantation after aortic graft replacement (n = 1). Thirty-day mortality was 8% (n = 1). The median follow-up duration was 44 months (range 24–151). Symptoms were relieved in 4 and persisted partially in 1, while symptom relief remained unknown in 1 patient who died during follow-up. Imaging after a median of 34 months (range 2–134) after the operation showed patent ASA revascularization in all patients and no endoleaks in the hybrid group. CONCLUSIONS Surgical and hybrid repair allows satisfying results in patients with symptomatic and/or aneurysmal ASA. The optimal procedure has to be defined on an individual patient basis. Further studies, preferably with a multicentre approach, are required to answer more specific questions on the management of these patients and especially to assess long-term results following hybrid repair.
