Background: We report a rare case of delayed, symptomatic thoracic endograft thrombosis after the initial thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury which was successfully retreated with a redo TEVAR, followed by open conversion due to recurrent partial occlusion of the distal edge of the endografts. Methods: Two years ago, a 22-year-old man had undergone an emergency TEVAR for blunt thoracic aortic injury. A Zenith Cook 22 × 100 mm (Cook Incorporated, Bloomington, IN) endograft was used. Six months later, he underwent an emergency endovascular relining of the endograft using the same type of device. The multiorgan perfusion was completely restored except for the spinal cord injury. After 8 months, a recurrent partial occlusion of the distal edge of the second graft was documented. The thoracic aorta was replaced with a 22-mm silver-coated graft (Maquet Spain, SLU). Results: Histology examination showed a neointimal formation and thickening and fibrosis of the inner 1/3 of the media with loss of smooth muscle cells and increase of the elastic fibers. Conclusions: The need for secondary interventions or open conversion because of potential complications after TEVAR for traumatic aortic injury is an additional consideration when weighing the risks and benefits of endovascular repair and subsequent surveillance strategies.

Abstract

Background: We report a rare case of delayed, symptomatic thoracic endograft thrombosis after the initial thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury which was successfully retreated with a redo TEVAR, followed by open conversion due to recurrent partial occlusion of the distal edge of the endografts. Methods: Two years ago, a 22-year-old man had undergone an emergency TEVAR for blunt thoracic aortic injury. A Zenith Cook 22 × 100 mm (Cook Incorporated, Bloomington, IN) endograft was used. Six months later, he underwent an emergency endovascular relining of the endograft using the same type of device. The multiorgan perfusion was completely restored except for the spinal cord injury. After 8 months, a recurrent partial occlusion of the distal edge of the second graft was documented. The thoracic aorta was replaced with a 22-mm silver-coated graft (Maquet Spain, SLU). Results: Histology examination showed a neointimal formation and thickening and fibrosis of the inner 1/3 of the media with loss of smooth muscle cells and increase of the elastic fibers. Conclusions: The need for secondary interventions or open conversion because of potential complications after TEVAR for traumatic aortic injury is an additional consideration when weighing the risks and benefits of endovascular repair and subsequent surveillance strategies.
