Surgical treatment of an aneurysm of the aberrant right subclavian artery involving an aortic arch aneurysm and coronary artery disease.

A 55-year-old man presented with clinical signs of an aortic arch aneurysm. Angiography, MRI and CT demonstrated an aortic arch aneurysm and an aneurysm of the aberrant right subclavian artery. Coronary angiography revealed 95% stenosis in the right coronary artery. Right common carotid artery-right subclavian artery bypass, arch graft replacement and coronary artery bypass grafting were performed successfully. The use of internal shunt tube, hypothermic circulatory arrest and selective cerebral perfusion were useful methods in prevention of cerebral ischemia during surgical reconstruction of the aortic arch. To our knowledge, this is the first report in the literature of a successfully managed case with an aneurysm of an aberrant right subclavian artery involving an aortic arch aneurysm and coronary artery disease.
