ABSTRACT
Abstract Takayasu's arteritis is a type of primary systemic vasculitis that affects medium and large arteries, including the aorta and its main branches, as well as the pulmonary and coronary arteries. Although rare in children, it is the third most common vasculitis in the pediatric population, often with delayed diagnosis due to the nonspecific presentation of clinical symptoms in its initial phase. This is a case of a 16-year-old girl with a giant ruptured abdominal aortic aneurysm, who needed surgery on an emergency basis. The etiological aspects involved in aneurysms in young patients are also addressed.

ABSTRACT
O avanço tecnológico da cirurgia endovascular no tratamento de aneurismas de aorta vem permitindo que uma maior quantidade de pacientes, antes considerados inaptos para essa abordagem, beneficie-se dessa modalidade terapêutica. Apesar da atual disponibilidade de endopróteses com alta conformabilidade, casos com anatomia desfavorável permanecem um desafio para os cirurgiões. Descrevemos um caso anatomicamente desfavorável, resolvido com sucesso pela técnica endovascular, utilizando-se uma manobra não convencional.
The advances in endovascular surgery for treatment of aortic aneurysms have allowed a greater number of patients, who were previously considered unsuitable for the approach, to benefit from this therapeutic modality. Despite the current availability of highly comfortable endografts, cases with unfavorable anatomy remain a challenge for surgeons. We report a case with difficult anatomy that was successfully managed using an unconventional endovascular technique.
