Emergency embolization of a ruptured renal artery aneurysm (RAA). (A) Renal arteriogram demonstrated the ruptured RAA (arrow) with four efferent branches (arrowheads). (B) Renal arteriogram after coil embolization showed occlusion of the aneurysm with patent branches, and the classification of occlusion was classified as class II as per the Modified Raymond-Roy Classification (MRRC). (C) Two years later, recurrence of the aneurysm and increased contrast filling in the aneurysmal neck was detected on digital subtraction angiography (DSA). (D) DSA after re-embolization showed complete embolization of the aneurysm and classified as MRRC class I.
