Thoracic endovascular aortic repair for traction-induced aortic avulsion injury in neurofibromatosis type 1

Abstract

Rupture of intercostal artery aneurysms has been reported in patients with neurofibromatosis type 1. Many reports have demonstrated the efficacy of endovascular interventions. Herein, we present a case of successful treatment with thoracic endovascular aortic repair for traction-induced avulsion injury of the previously embolized intercostal artery. We further report the potential postoperative risk of rapid aneurysmal enlargement, possibly owing to changes in the thoracic arterial regional network. Even after successful treatment, vascular surgeons should pay attention to other aneurysmal events in the acute phase and avulsion injuries in the chronic phase. Close follow-up is essential.
