Abstract
O rim em ferradura é uma das anomalias urológicas congênitas mais comuns e está presente em cerca de 0,12% dos pacientes com aneurisma de aorta abdominal. O reparo cirúrgico convencional está associado a dificuldades técnicas que provavelmente aumentam a morbidade e a mortalidade, mas que podem ser evitadas com o tratamento endovascular. Relatamos um caso de um paciente de 64 anos com rim em ferradura e aneurisma de aorta abdominal, que foi submetido ao reparo endovascular do aneurisma com sucesso.
Highlights
Horseshoe kidney is a very frequent congenital abnormality, with an incidence of one in every 600 to 800 individuals[1]
According to Ferko et al, horseshoe kidneys are found in every 200 cases of patients with abdominal aortic aneurysms (AAA) treated surgically[2]
Resection of an AAA associated with horseshoe kidney involves two basic problems: first, renal parenchyma are present, often covering the aneurysm and making its exposure more difficult; second, aneurysm resection is usually very difficult because the lesion is present in anomalous arteries
Summary
Horseshoe kidney is a very frequent congenital abnormality, with an incidence of one in every 600 to 800 individuals[1]. Resection of an AAA associated with horseshoe kidney involves two basic problems: first, renal parenchyma are present, often covering the aneurysm and making its exposure more difficult; second, aneurysm resection is usually very difficult because the lesion is present in anomalous arteries. In this scenario, endovascular therapy emerges as a very attractive procedure for the treatment of AAAs in patients with horseshoe kidneys, especially because of its less aggressive nature and increased effectiveness in this type of patient. The problem has only been addressed with a focus on conventional surgical treatment[3]
