- Abstract
- (en) INTRODUCTION: aortic aneurysms involving the renal and visceral arteries are endovascular challenges, especially for emergencies. We report a case of ruptured thoracoabdominal aortic aneurysm (TAAA) in a morbidly obese 71-year-old man. The patient was admitted with a stable hemodynamic state. A computed tomography angiogram (CTA) revealed a contained ruptured TAAA with an occluded celiac trunk and left renal artery due to previous nephrectomy. Due to the emergency and his comorbidities, we performed an endovascular aortic repair with the sandwich technique and 2 chimneys. Two bridging stents (chimneys) were deployed between the aorta and the target vessels (superior mesenteric and right renal arteries) in a space created in-between 2 aortic straight endografts. Ten days postoperative, acute renal failure appeared and right renal stent occlusion was diagnosed on CTA. Unfortunately, no adequate kidney revascularization could be obtained, requiring permanent hemodialysis. At a 3-month follow-up visit, the patient did well with stable aneurysm dimensions. CONCLUSIONS: encouraging outcomes of chimney-EVAR techniques, comparable to those in published reports of fenestrated-EVAR and branched-EVAR, support this procedure as a valid off-the-shelf available alternative in emergency situations. Nevertheless, only few midterm results achieved are actually available and long-term outcomes are actually unknown.
