Correção endovascular de aneurisma da artéria renal com a técnica de Moret: caso clínico

Abstract

Resumo O aneurisma da artéria renal é uma patologia rara, presente em 0,01-1,30% da população e está frequentemente associado a hipertensão arterial. Pela sua elevada taxa de sucesso, o tratamento endovascular é considerado a primeira opção terapêutica. Os autores apresentam um caso de um aneurisma da artéria renal de 36 mm de diâmetro, corrigido através da técnica de Moret. Esta consiste na embolização do aneurisma, enquanto o colo é temporariamente ocluído com um balão. Os autores discutem as vantagens das diferentes técnicas endovasculares e relacionam-nas com as características anatómicas do aneurisma, fundamentando assim a opção terapêutica tomada.Abstract Renal artery aneurysm is a rare pathology, present in 0.01-1.30% of the population and it is frequently associated with hypertension. Endovascular treatment is the first option due to its low morbidity and mortality. The authors report a clinical case of a renal artery aneurysm with a 36 mm of diameter treated with Moret's technique. It consists in aneurysm embolization while neck is temporary occluded with a balloon. The authors discuss the advantages of the endovascular techniques and relate them with the aneurysm anatomy, justifying their therapeutic option.

Ruptured Renal Artery Aneurysm in a Pregnant Woman: Case Report and Literature Review

“…4,5 However, the prognosis of a ruptured RAA is not favorable, mainly for pregnant women, with maternal death rates varying between 50 and 92%, and fetal death rates ranging between 82 and 100%. 6 The most common RAA etiology is that the disease results from the loss of elastic fibers and from the decrease of the smooth muscle tissue of the middle layer 1 The risk factors include systemic arterial hypertension (SAH), atherosclerosis, fibromuscular dysplasias, changes in collagen metabolism, inflammatory diseases, penetrating or blunt trauma, female gender, being 60 years old, and pregnancy. 3,4 It is believed that the increase of plasma volume, intra-abdominal pressure, hormonal-metabolic changes, and hyperdynamic state in pregnancy may be contributing factors not only for the increased size but also for the rupture of these aneurysms.…”

“…The most accepted etiology is that the disease results from the loss of elastic fibers and from the decrease of the smooth muscle tissue of the middle layer. 1 Pregnancy has characteristics that may contribute to the increased size and rupture of RAAs, such as the hyperdynamic state and increased intraabdominal pressure. 2 The rupture of RAAs may cause symptoms that can be confused with other common conditions during pregnancy.…”
