Total Thrombosis of Bifurcated Endoprosthesis: A Rare Complication of Endovascular Treatment of Abdominal Aortic Aneurysm

摘要

Background : Aortic stents are a therapeutic alternative to open surgery of abdominal aortic aneurysms. We report a case of treatment of an abdominal aortic aneurysm with a bifurcated stent, complicated by total thrombosis. Aim : The purpose of this presentation was to understand the causes, mechanisms, incidents and accidents that contributed to this complication. Case Presentation : A 48-year-old man patient with a history of high blood pressure, ischemic heart disease, chronic obstructive pulmonary disease, who was found during a surveillance check-up, an infra-renal abdominal aorta aneurysm measured at 56 mm in diameter, asymptomatic but progressive. The indication of an endovascular treatment by the placement of a bifurcated prosthesis was posed and accepted. Thrombosis of the two limbs was intra-operative, upper-end migration without endoleak at 4 months postoperative, total thrombosis of the stent at 13 months postoperatively. Explantation of the stent followed by aortobi-iliac bypass was finally performed in the 15~(th) month. Conclusion : The cardiopulmonary antecedents, the anatomical and evolutionary characteristics of the aneurysm could have played a role in the occurrence of the complications observed in this patient.
