The rupture of the giant renal aneurysm into the renal pelvis with successful emergency arterial embolization : A case report

　76歳女性．遊技店で倒れているところを発見され，CTで長径8cm大の右腎動脈瘤および膀胱タンポナーデを認め，救急搬送となった．腎動脈瘤破裂の診断でTAEを施行した．TAE前後で腎機能の著明な低下を認めず，腎摘出術を回避できた症例を経験したので，若干の文献的考察を加えて報告する．

Abstract

We report a case of ruptured renal artery aneurysm which was successfully treated by trancatheter arterial embolization (TAE). A 76-year-old woman was brought to the ambulance because computed tomography (CT) scan revealed a ruptured right renal artery aneurysm with 8 cm in diameter and blood clots in the bladder. Emergent TAE using micro coils was performed. Her condition has stabilized and renal function was not significantly deteriorated after TAE. We consider that TAE for the rupture of the renal artery aneurysm would become the treatment option (Rinsho Hinyokika 73 : 767-770, 2019).
