Técnicas e Táticas no Tratamento Endovascular do Aneurisma da Artéria Renal

Técnica de remodelamento com uso de stents em T e molas para tratamento de aneurisma renal complexo

“… 7 Although rupture is a relatively infrequent phenomenon (5 to 10%), it is associated with high mortality rates (80%). 1 In our case, the RAA was an incidental finding during investigation of refractory SAH of renovascular etiology.…”

“… 1 , 2 , 5 This disease is more common in females, because of the strong association with renal fibromuscular dysplasia, 1 , 6 but it is also linked to atherosclerosis, infections, trauma, Kawasaki disease, Marfan Syndrome, vascular dysplasias, and polyarteritis nodosa (PAN). 1 , 3 The majority of patients are asymptomatic, but some present with symptoms such as SAH, renal ischemia, hematuria, and flank pain, but the relationships are not well established. Complications involve renal vascular hypertension, renal thrombosis and emboli, renal infarct, and rupture.…”

“…The number of cases diagnosed has been increasing because of wider use of imaging methods such as Doppler ultrasonography and computed tomography angiography (CTA). 1 , 2 …”

“… 2 As endovascular techniques evolved, treatment of RAA using percutaneous repair became possible, offering reduced surgical trauma, shorter postoperative hospital stay, and lower morbidity, when compared to open surgical treatment. 1 , 4 However, treatment of complex RAA in which it is necessary to preserve branches emerging from the aneurysm that supply the poles of the kidneys remains a therapeutic challenge. 1 - 4 New techniques and materials developed within interventional neurology appear to offer promising options for treatment of these complex RAA.…”
