Surgical and endovascular treatment of symptomatic aberrant right subclavian artery (arteria lusoria).

Right aberrant subclavian artery, also called arteria lusoria, is one of the most common intrathoracic arterial anomalies. Although mostly asymptomatic, the retroesophageal and retrotracheal course of the lusorian artery might result in unspecific thoracic pain, dysphagia, dyspnea, arterioesophageal or arteriotracheal fistulae with hematemesis or hemoptysis, and aneurysmal formation with relevant risk of rupture. The purpose was to present our experience with six patients with a symptomatic aberrant right subclavian artery, two patients with dysphagia or dyspnea caused by a nonaneurysmal lusorian artery, and four patients with arteria lusoria aneurysms. The operative procedures performed are described and discussed in view of the data reported in the literature. According to the classification of the lusorian artery pathology, a combined intervention with right subclavian artery transposition, distal or proximal lusorian artery ligation or proximal endovascular occlusion for nonaneurysmal disease, or endovascular thoracic aortic stent graft implantation for lusorian artery aneurysms seems to be an additional and minimally invasive approach with promising midterm results.
