A Case of Secondary Stent-grafting for Rupture of Pararenal-abdominal Aneurysm Three Year after EVAR using a Fenestrated Stent Graft and Covered Renal Stent

Abstract

We report a case of rupture of pararenal abdominal aneurysm after endovascular abdominal aneurysm repair (EVAR), using the covered bi-renal stent and fenestrated Zenith stent graft. A 74-year-old man, had polycystic kidney disease, complained the sudden abdominal pain and shock in ambulance to our hospital. Computed tomography showed a type III endoleak between the covered stent inserted in right renal artery and main body of fenestrated stent graft, and aneurysm ruptured. The patient was treated by secondary endovascular stent grafting with obstruction for bilateral renal artery. After EVAR, the blood dialysis required. If the new appearance of type III endoleak is seen after EVAR, surgical treatment should be considered for the endoleak immediately.
