Clasificación y posibilidades terapéuticas de los aneurismas saculares de arteria renal

Summary Introduction The treatment of saccular aneurysms of the renal artery, at the present time, may include various options which are both conservative (percutaneous) and surgical. Objective To review our experience and classify saccular aneurysms of the renal artery so as to facilitate their management and treatment. Patients and methods Analysis of data recorded prospectively showed that eight patients had been treated for saccular aneurysms of the renal artery situated in the main trunk, first bifurcation or lobular branch between January 1978 and June 2000. They represented 30.7% of all aneurysms of the renal artery. Results Three types of saccular aneurysms were differentiated mainly on therapeutic criteria: type I, aneurysm of the ostium of the renal artery, generally associated with an aneurysm of the aorta (two cases); type II, broad-basedpediculated saccular aneurysm (four cases) and type III, narrow-basedpediculated saccular aneurysm (two cases). Conclusion The classification of saccular aneurysms of the renal artery into the three types described may facilitate decisions regarding the different options for treatment. We believe that, at the present time, types I and II require basically surgical treatment. Type III cases may be initially treated percutaneously.
