Pseudoaneurisma traumático de troncos supra-aórticos: tratamiento endovascular. Casos clínicos

The traditional treatment of traumatic lesions of the aortic arch branches requires extended surgical exposures, not exempt of morbidity and mortality. Over the last decade, devices that allow a minimally invasive treatment, have been developed. The vessel can be repaired without direct exposure, using an endovascular procedure. We report three patients with traumatic pseudoaneurysms of the left subclavian, brachiocephalic and left common carotid arteries, respectively. All lesions were successfully repaired with the insertion of an endograft. Although long term results of these procedure are unknown, repair of a future stenosis or occlusion is less complicated than the treatment required by the original lesion. Endoluminal repair appears as a safe, efficient and less invasive treatment for these lesions. (Rev Méd Chile 2002; 130: 1027-32)
