Chimney technique for left subclavian artery restoration -Two cases presentations-

Abstract

Introduction: Left subclavian artery revascularization (LSAR) is performed in the setting of thoracic endovascular repair (TEVAR). In recent years, the chimney technique is an effective method of LSAR. Cases: Two case reports analyze our experience in the chimney technique for the LSAR. In the first case, a young male underwent in a TEVAR due to an aortic isthmus rupture. In the second case, a male underwent in elective endovascular repair of thoracic aortic aneurysm and in the second time he underwent in an endovascular abdominal aortic aneurysm repair. In 3 months postoperatively, the second man’s follow-up CTA showed that the stents were well formed and no obvious endoleak was noticed. Conclusion: The LSAR in patients who underwent in TEVAR decreases the risk of stroke and upper limb ischemia. Several minimally invasive procedures have been employed to manage this, one of them is the chimney graft technique.
