Rupture of the Remaining Renal Artery Aneurysm While Waiting for Stage 2 Surgery for a Patient with Bilateral Renal Artery Aneurysms and Multiple Aneurysms.

A 21-year-old man was referred to our department for treatment of multiple aneurysms, including bilateral renal artery aneurysms. He was clinically diagnosed with Loeys-Dietz syndrome. So, we developed a 2-stage surgical strategy. The first surgery involved reconstructing the right renal artery and replacing part of the abdominal aorta, bilateral common iliac artery, and bilateral internal and external iliac arteries with a synthetic graft. Although stent grafting of the left renal artery aneurysm had been scheduled for the second surgery, sudden rupture of the left renal artery aneurysm forced us to perform emergency renal artery reconstruction.
