Abstract

The aberrant right subclavian artery or arteria lusoria (AL) is the most frequent anatomical variation of the supra-aortic trunks (SAT). Treatment is only warranted in the presence of an aneurysm because of the risk of rupture, or in symptomatic cases with signs of compression of the esophagus or the trachea, with embolisms causing right upper limb ischemia of vertebrobasilar cerebrovascular accidents. The conventional surgical treatment of AL is the closure of the origin of AL and the revascularization of the right subclavian artery through a left thoracotomy. With the appearance of endovascular techniques, some of these patients can be treated with minimally invasive hybrid techniques. The aim of this study is to evaluate the feasibility of the endovascular treatment of AL based on the radioanatomical analysis of the thoracic angio-computed tomographies. We analyzed 180 thoracic angio-computed tomographies using millimeter cuts (<1.2 mm) performed between 2010 and 2015 in the Nancy University Hospital in which an AL was fortuitously discovered. Symptomatic ALs and pediatric patients were excluded. The diameters of the SATs and the aorta and the distances between the SATs were measured. The data were processed with the t-test ...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
