Indications for surgery on renal artery aneurysms.

Indications for an operation on renal artery aneurysms include patients 1) with a rupture or an impending rupture, 2) with a possibility of pregnancy, 3) with hypertension and renin differentials suggesting remediable disease and 4) with functional or symptomatic impairment traceable to the aneurysm proper. If the aneurysm is calcified some temporization may be justified, although this observation alone should be only of secondary importance. The size of the aneurysm is likewise generally of secondary value. Of course, the patient's picture and expectancy need balancing in the decision. Conservative management in other situations is acceptable, particularly for the elderly.
