Resumo

O tratamento endovascular da doença aneurismática da artéria renal tem sido, cada vez mais, aceito como uma alternativa à cirurgia convencional, especialmente em casos de aneurismas complexos intra-parenquimatosos ou que comprometam a bifurcação da artéria renal. Os autores relatam a experiência do tratamento endovascular de uma paciente com aneurisma sacular da bifurcação da artéria renal direita, associado à hipertensão renovascular de difícil controle. Foi realizada a cateterização seletiva da artéria renal, com a inserção de micromolas no saco aneurismático. O aneurisma foi completamente ocluído com preservação total do fluxo sanguíneo renal. A evolução clínica foi satisfatória com redução significativa das medicações anti-hipertensivas. A angio-tomografia de controle, após o oitavo mês do procedimento, confirmou o sucesso do tratamento.

Abstract

Endovascular treatment of renal artery aneurysmal disease has been increasingly accepted as an alternative to conventional surgery, especially in cases of renal artery bifurcation or complex intrarenal aneurysms. The authors report a case of endovascular treatment of a saccular aneurysm of the right renal artery bifurcation associated with poorly controlled renovascular hypertension. Selective catheterization of the renal artery was performed and microcoils were inserted into the aneurysmal sac. The aneurysm was completely obliterated with total preservation of renal blood flow. Clinical evolution was satisfactory with significant reduction in anti-hypertensive drugs. Control tomographic angiography, after eight months, confirmed treatment success.
