Surgical treatment of recurrence of an aneurysm of aberrant right subclavian artery.
Overview
abstract
A 52-year-old woman underwent incomplete resection of an aneurysm of the aberrant right subclavian artery. Three years later she was hospitalized because of a right superior mediastinal mass on the chest X-ray and a new angiography revealed dilatation of the remaining part of the aberrant right subclavian artery near its origin and involving the adjacent thoracic aorta and the distal aortic arch. At surgery, a left posterolateral thoracotomy in the fourth intercostal space was performed. Using deep hypothermia and circulatory arrest the aneurysm was excised and the aortic tract adjacent to the aneurysm was replaced with a Dacron prosthesis.
